    Therapist Experience and Knowledge Acquisition in Internet-Delivered CBT for Social Anxiety Disorder: A Randomized Controlled Trial2012Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 7, nr 5, s. e37411-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Guided internet-delivered cognitive behavior therapy (ICBT) has been tested in several trials on social anxiety disorder (SAD) with moderate to large effects. The aims of this study were threefold. First, to compare the effects of ICBT including online discussion forum with a moderated online discussion forum only. Second, to investigate if knowledge about SAD increased following treatment and third to compare the effects of inexperienced versus experienced therapists on patient outcomes. Methods: A total of 204 participants with a primary diagnosis of SAD were included and randomized to either guided ICBT or the control condition. ICBT consisted of a 9-week treatment program which was guided by either psychology students at MSc level (n=6) or by licensed psychologists with previous experience of ICBT (n=7). A knowledge test dealing with social anxiety was administered before and after treatment. Measures of social anxiety and secondary outcomes dealing with general anxiety, depression, and quality of life were administered before and after treatment. In addition, a 1-year follow-up was conducted on the treated individuals. Results: Immediately following treatment, the ICBT group showed superior outcome on the Liebowitz Social Anxiety Scale self-report version with a between group posttreatment Hedges g effect size of g=0.75. In addition, significant differences on all the secondary outcomes were observed. Gains were well maintained one year later. Knowledge, as assessed by the knowledge test, increased following treatment with little gain in the control group. Therapist experience did not result in different outcomes, but experienced therapists logged in less frequently compared to the inexperienced therapists, suggesting that they needed less time to support patients. Discussion: We conclude that guided ICBT reduce symptoms of SAD, increase knowledge about SAD and that therapist experience does not make a difference apart from the finding that experienced therapist may require less time to guide patients.

    Tinnitus and short-term serial recall in stable versus intermittent masking conditions2009Inngår i: Scandinavian Journal of Psychology, ISSN 0036-5564, E-ISSN 1467-9450, Vol. 50, nr 5, s. 517-522Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The relation between tinnitus and short-term memory performance in varying background sounds is not well understood. In the present study a sample of 18 persons with tinnitus completed a serial recall test in three conditions, silence, masking and intermittent masking. The performance of a matched control group without tinnitus was also investigated. Based on the literature on the "irrelevant sound effect" we expected that the tinnitus group would perform worse during intermittent masking and that they would score lower overall compared to the control group. Results revealed no statistically significant differences between the groups, nor any group interaction within sound conditions for the serial recall test. Groups did however differ regarding subjective measures of concentration problems, anxiety and depression. Results are discussed in relation to thought suppression and distraction from tinnitus.

    Chronic Pain in Older Adults: A Controlled Pilot Trial of a Brief Cognitive-Behavioural Group Treatment2012Inngår i: Behavioural and Cognitive Psychotherapy, ISSN 1352-4658, E-ISSN 1469-1833, Vol. 40, nr 2, s. 239-244Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Chronic pain is a common condition among older adults. While cognitive behaviour therapy (CBT) has been tested in numerous studies on adults and children there are fewer studies on older persons. The objective of this study was to investigate the effects of a six-session CBT group treatment for older persons with chronic pain. As a secondary aim we investigated whether treatment credibility was associated with outcome. Method: We included 21 persons (mean age = 72.0 years) who were randomly allocated to either a waitlist condition or treatment consisting of applied relaxation, with the addition of problem solving, assertiveness, communication strategies, sleep management, and relapse prevention. Results: Few statistically significant effects were found on measures of pain, mood, anxiety, and quality of life; however, a significant treatment effect with a between group effect size of d = 1.0 was observed with respect to perceived ability to function despite the discomfort of pain. Conclusion: The study provides some preliminary support for the use of group-based CBT with a focus on applied relaxation for older adults with chronic pain.

    Therapeutic alliance in guided internet-delivered cognitive behavioural treatment of depression, generalized anxiety disorder and social anxiety disorder2012Inngår i: Behaviour Research and Therapy, ISSN 0005-7967, E-ISSN 1873-622X, Vol. 50, nr 9, s. 544-50Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Guided internet-delivered cognitive behaviour therapy (ICBT) has been found to be effective in several controlled trials, but the mechanisms of change are largely unknown. Therapeutic alliance is a factor that has been studied in many psychotherapy trials, but the role of therapeutic alliance in ICBT is less well known. The present study investigated early alliance ratings in three separate samples. Participants from one sample of depressed individuals (N = 49), one sample of individuals with generalized anxiety disorder (N = 35), and one sample with social anxiety disorder (N = 90) completed the Working Alliance Inventory (WAI) modified for ICBT early in the treatment (weeks 3-4) when they took part in guided ICBT for their conditions. Results showed that alliance ratings were high in all three samples and that the WAI including the subscales of Task, Goal and Bond had high internal consistencies. Overall, correlations between the WAI and residualized change scores on the primary outcome measures were small and not statistically significant. We conclude that even if alliance ratings are in line with face-to-face studies, therapeutic alliance as measured by the WAI is probably less important in ICBT than in regular face-to-face psychotherapy.

    Internet-Based Exposure Treatment Versus One-Session Exposure Treatment of Snake Phobia: A Randomized Controlled Trial2013Inngår i: Cognitive Behaviour Therapy, ISSN 1650-6073, E-ISSN 1651-2316, Vol. 42, nr 4, s. 284-291Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this study, the authors compared guided Internet-delivered self-help with one-session exposure treatment (OST) in a sample of snake phobic patients. A total of 30 patients were included following a screening on the Internet and a structured clinical interview. The Internet treatment consisted of four weekly text modules which were presented on a web page, a video in which exposure was modelled, and support provided via Internet. The OST was delivered in a three-hour session following a brief orientation session. The main outcome was the behavioural approach test (BAT), and as secondary measures questionnaires measuring anxiety symptoms and depression were used. Results showed that the groups did not differ at post-treatment or follow-up, with the exception of a significant interaction for the BAT in favour of the OST. At post-treatment, 61.5% of the Internet group and 84.6% of the OST group achieved a clinically significant improvement on the BAT. At follow-up, the corresponding figures were 90% for the Internet group and 100% for the OST group (completer sample). Within-group effect sizes for the Snake Phobia Questionnaire were large (d=1.63 and d=2.31 for the Internet and OST groups, respectively, at post-treatment). It is concluded that guided Internet-delivered exposure treatment is a potential treatment option in the treatment of snake phobia, but that OST probably is better.

    Internet-Based Self-Help Versus One-Session Exposure in the Treatment of Spider Phobia: A Randomized Controlled Trial2009Inngår i: Cognitive Behaviour Therapy, ISSN 1650-6073, E-ISSN 1651-2316, Vol. 38, nr 2, s. 114-120Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The authors compared guided Internet-delivered self-help with one session of live-exposure treatment in a sample of spider-phobic patients. A total of 30 patients were included following screening on the Internet and a structured clinical interview. The Internet treatment consisted of five weekly text modules, which were presented on a web page, a video in which exposure was modelled, and support provided via Internet. The live-exposure treatment was delivered in a 3-hr session following a brief orientation session. The main outcome measure was the behavioural approach test (BAT), and as secondary measures the authors used questionnaires measuring anxiety symptoms and depression. Results showed that the groups did not differ at posttreatment or follow-up, with the exception of the proportion showing clinically significant change on the BAT. At posttreatment 46.2% of the Internet group and 85.7% in the live-exposure group achieved this change. At follow-up the corresponding figures were 66.7% for the Internet group and 72.7% for the live treatment. Within-group effect sizes for the spider phobia questionnaire were large (d = 1.84 and 2.58 for the Internet and live-exposure groups, respectively, at posttreatment). The authors conclude that guided Internet-delivered exposure treatment is a promising new approach in the treatment of spider phobia.

    Modes of Apprehension, and Indicators thereof, in Visual Discrimination of Relative Mass2009Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Perception is a fundamental function because it allows organisms to be in contact with the environment and adjust to environmental conditions. Humans also possess higher intellectual functions, which allow for elaborate handling of perceptually obtained information. The thesis concerns a distinction between an inferential ("cognitive") mode and a (direct-)perceptual mode of apprehension, and a notion of perceptual skill acquisition as a transition from the inferential to the perceptual mode. The mode distinction and the mode-transition model was formulated by Runeson, Juslin, and Olsson (2000) within the ecological direct-perception framework (Gibson, 1966, 1979).

    The modes of apprehension were investigated in an experimental paradigm that concerned visual perception of the relative mass of two colliding objects. The relative mass is specified by an optical variable in the collision movement pattern, which observers may pick up while functioning in the perceptual mode. However, novices often rely on other, nonspecifying, optical variables that may constitute cues that are used in the inferential mode (Runeson et al., 2000).

    Four tentative mode indicators were employed: participants' realism of confidence, introspective mode reports, amplitudes of brain event-related potentials, and response times. Generally, the results did not support the mode-transition model of skill acquisition. Furthermore, results suggested that reliance both on the specifying and nonspecifying variables might have occurred either in the inferential or in the perceptual mode. However, the mode indicators may not have captured mode as intended. For instance, the discriminability of used optical variables, and not the mode of apprehension, may have affected both amplitudes of event-related potentials and mode reports.

    It is argued that the mode-transition model and the distinction between two modes of apprehension should be further investigated employing other methodologies, and, furthermore, that the mode distinction has a place within an ecological framework.

    Abstract [en]

    Participants' usage of informational variables in learning visual relative-mass discrimination in collisions was tracked by means of PROBIT correlations. Four groups received feedback that was true or accorded with either of three non-specificational cue variables. A majority in each group adopted the feedback but several participants defied the false feedback. Unlike in previous research, the fit to data of the relative-mass invariant could not be bettered by post hoc linear combinations of the cues. Discriminability was lower in the use of the invariant. Analytic complexity was rejected as an explanation for discriminability differences. A "smart mechanism" for pickup of the relative-mass invariant was developed as an extension of G. Johansson's (1950/1994) vector model.

    Abstract [en]

    In dynamic event perception, one issue is whether direct perception or cue-based inferences explains learning and performance. For visual discrimination of relative mass of colliding objects, Runeson, Juslin, and Olsson (2000) found that observers change from an inferential to a direct-perceptual mode of apprehension during practice, as indicated by lower confidence in their judgments. Unlike Runeson et al. (2000), we scored confidence against the variables used in individual blocks and analyzed collision-subsets, thereby counteracting inflated confidence scores. A majority of 40 novice participants used a nonspecifying variable and functioned inferentially, as indicated by realistic confidence. Five novices used the mass-ratio invariant and were overconfident therein. Ten participants received feedback based on the most-used nonspecifying variable. Despite feedback suggesting specificity of the variable, they continued to use the variable inferentially. After practice based on the invariant, 7 out of 10 used the invariant. An unexpected  dearth of underconfidence for invariant usage is explained by fluctuations in variable usage. Methodological problems in the use of confidence as a mode indicator are discussed.

    Abstract [en]

    In visual judgments of relative mass of colliding objects observers may function in either a perceptual or an inferential mode of apprehension (Runeson, Juslin, & Olsson, 2000). This finding was based on participants’ over/underconfidence in their judgments. Also phenomenological mode reports, for which participants indicated whether they “saw” or “inferred” the relative mass in each trial, have been used as mode indicators (Andersson, Kreegipuu, Allik, & Runeson, 2009). The present study showed that over/underconfidence and mode reports are not congruent as mode indicators: in Experiments 1 and 2, participants’ over/ underconfidence was about the same in “saw” and “inferred” trials. Furthermore, in Experiment 3, unexpectedly judgments of relative exit-speed did not engender underconfidence. Hence, one or both indicators do not well enough distinguish the modes of apprehension.

    Reactions to novelties: Developmental aspects1999Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The present thesis considers different aspects of infants' and children's reactions to novelties, that is, unfamiliar persons, objects, and situations. In Study I, the developmental phenomenon stranger wariness was investigated from a temperamental perspective. Stranger wariness at age 10 months was found to be marginally predicted by 5-month individual variation in reactions to frustration, to sensory stimulation, and to novelties and to be predictive of 2-year social inhibition. These results indicate that 10-month stranger wariness does not only reflect a developmental transition but also an individual disposition to be responsive to social novelties.

    In line with what has been suggested for the behavioral inhibition construct, Study II showed that 2-year-olds' reactions to social and non-social novelties should be considered as belonging to one construct. Furthermore, the relations within and between latency, negative/inhibited and positive/approaching reactions to social and non-social novelties were found to be very similar, implying that identifying children as uninhibited means that they are disposed not only towards lack of negative/inhibited reactions, but also towards approaching/positive reactions when confronted with novelties.

    Study III concerned preschool social inhibition in relation to attachment security and social experiences in terms non-parental care. The relative contributions of the three variables to school-age social competence with peers and social self-esteem were also investigated. It was found that attachment security and social inhibition were unrelated to each other and that they made significant independent contributions to the explanation of social competence, whereas social self-esteem was only predicted by preschool social inhibition.

    Do Bettors Correctly Perceive Odds?: Three Studies of How Bettors Interpret Betting Odds as Probabilistic Information2015Inngår i: Journal of Behavioral Decision Making, ISSN 0894-3257, E-ISSN 1099-0771, Vol. 28, nr 4, s. 331-346Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper reports on three studies investigating how accurately bettors (=people who regularly bet on sports events) interpret the probabilistic information implied by betting odds. All studies were based on data collected by web surveys prompting a total of 186 experienced bettors to convert sets of representative odds into frequency judgments. Bayesian statistical methods were used to analyze the data. From the results, the following conclusions were made: (i) On the whole, the bettors produced well-calibrated judgments, indicating that they have realistic perceptions of odds. (ii) Bettors were unable to consciously adjust judgments for different margins. (iii) Although their interval judgments often covered the estimates implied by the odds, the bettors tended to overestimate the variation of expected profitable bets between months. The results are consistent with prior research showing that people tend to make accurate probability judgments when faced with tasks characterized by constant and clear feedback.

    Perception aspects on perspective aircraft displays2003Inngår i: Displays (Guildford), ISSN 0141-9382, E-ISSN 1872-7387, Vol. 24, nr 1, s. 1-13Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This report presents two experiments in the area of perspective aircraft displays. The research focus was to explore the possibilities to understand symbolic and symbol relations in the 3D environment. In the first experiment the subjects' ability to distinguish between five different aircraft symbol shapes were investigated together with the perception of their heading in the 3D space. The perspective used in this experiment was egocentric. In the second experiment the judgment of the spatial relation between an own-ship symbol and a target symbol was investigated. Thus, in this case, the perspective was exocentric and two aspect angles were used for the camera position. Both experiments were carried out in non-dynamic scenarios. The display character was topographic with a superposed grid at the ground surface. The overall conclusion from the experiments is that judgment of direction in 3D presentations is very difficult in these static scenarios. Symbol recognition of 3D pictorial symbols is problematic for complicated symbol shapes as well, depending on different appearances for various symbol headings in the 3D space.

    Readability of vertically vibrating aircraft displays1999Inngår i: Displays (Guildford), ISSN 0141-9382, E-ISSN 1872-7387, Vol. 20, nr 1, s. 23-30Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Vibrations pose a problem to the visual system. The vibrations in aircraft are mainly vertical and cause reading errors when the pilots read the instruments. In three experiments, reading capability was tested during vertical vibration of modern military aircraft, using symbols presented on a computer monitor. The results showed that complexity of symbols have a significant effect on the performance. The orientations of symbols were also of importance for their readability. Indexes made up of horizontally oriented lines were found to be especially difficult to read during vertical vibration. Orienting them 45° up or down improved readability in a significant way. The size of the symbols was found to be of importance especially when they were horizontally oriented.

    Låt inte stress hindra dig!: Hur övningar i perspektivtagande inspirerade av ACT kan öka psykologisk flexibilitet i arbetslivet samt minska stressresponsens skadeverkningar2014Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Stressade medarbetare kostar pengar, sänker produktivitet och bidrar till ohälsa. Genom perspektivtagande kan vi ändra förhållningssätt till vårt psykologiska innehåll. ”Självet-som-kontext” ingår i ”psykologisk flexibilitet” och innebär att ta perspektiv till sitt psykologiska innehåll. ”Prosocialt hjälpbeteende” är att ta ett nytt perspektiv till andra. Vår studie undersöker om interventioner i självet-som-kontext och prosocialt hjälpbeteende har effekt på psykologisk flexibilitet i arbetslivet, självupplevd stress samt självet-som-kontext. Även sambandet mellan beroendevariablerna undersöktes. Vi använde en mixad AB-design med intervention. Resultatet visade på minskad självupplevd stress (p=.005) utan effekt av interventionerna (p=.771). Vi fann skillnad mellan interventionerna på psykologisk flexibilitet i arbetslivet (p=.037), men förändringen var inte signifikant (p=.597) Effektstorleken för samtliga skillnader var låg (η2p = .1). Samtliga beroendevariabler korrelerar signifikant (p=<.001).

    Emotional Empathy, Facial Reactions, and Facial Feedback2010Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The human face has a fascinating capability to express emotions. The facial feedback hypothesis suggests that the human face not only expresses emotions but is also able to send feedback to the brain and modulate the ongoing emotional experience. It has furthermore been suggested that this feedback from the facial muscles could be involved in empathic reactions. This thesis explores the concept of emotional empathy and relates it to two aspects concerning activity in the facial muscles. First, do people high versus low in emotional empathy differ in regard to in what degree they spontaneously mimic emotional facial expressions? Second, is there any difference between people with high as compared to low emotional empathy in respect to how sensitive they are to feedback from their own facial muscles? Regarding the first question, people with high emotional empathy were found to spontaneously mimic pictures of emotional facial expressions while people with low emotional empathy were lacking this mimicking reaction. The answer to the second question is a bit more complicated. People with low emotional empathy were found to rate humorous films as funnier in a manipulated sulky facial expression than in a manipulated happy facial expression, whereas people with high emotional empathy did not react significantly. On the other hand, when the facial manipulations were a smile and a frown, people with low as well as high emotional empathy reacted in line with the facial feedback hypothesis. In conclusion, the experiments in the present thesis indicate that mimicking and feedback from the facial muscles may be involved in emotional contagion and thereby influence emotional empathic reactions. Thus, differences in emotional empathy may in part be accounted for by different degree of mimicking reactions and different emotional effects of feedback from the facial muscles.

    Abstract [en]

    This study investigates whether people High in emotional empathy are more facially reactive than are people Low in emotional empathy when exposed to pictures of angry and happy facial expressions. Facial electromyographic activity was measured from the corrugator and the zygomatic muscle regions. In accordance with the predictions, the High empathic group reacted with larger corrugator activity to angry as compared to happy faces and with larger zygomatic activity to happy faces. However, the Low empathic group did not differentiate between the angry and happy stimuli at all. The High empathic group, as compared to the Low empathic group, also rated the angry faces as expressing more anger and the happy faces as being happier. It is concluded that high empathic people are particularly sensitive in reacting with facial reactions to facial expressions and that this ability is accompanied by a higher level of empathic accuracy.

    Abstract [en]

    We studied if emotional empathy is related to sensitivity to facial feedback. The participants, 112 students, rated themselves on the questionnaire measure of emotional empathy (QMEE) and were divided into one high and one low empathic group. Facial expressions were manipulated to produce a happy or a sulky expression. During the manipulation, participants rated humorous films with respect to funniness. These ratings were the dependent variable. No main effect of facial expression was found. However, a significant interaction between empathy and condition indicated that the high as compared to the low empathic group rated the films as being funnier in a happy condition and a tendency to be less funny in a sulky condition. On the basis of the present results we suggest emotional empathy to be one important and previously ignored factor to explain individual differences in effects of facial feedback.

    People with a low but not people with a high degree of emotional empathy have been found to rate humorous films as funnier in a sulky versus a happy facial manipulation, in contrast to what the facial feedback hypothesis predicts (Andréasson & Dimberg, 2008). Experiment 1 replicated this finding with people with extra ordinary high or low degree of emotional empathy. Interestingly, when the facial manipulations were a smile versus a frown, as in experiment 2, people with low as well as high emotional empathy reacted as predicted by the facial feedback hypothesis. In conclusion, emotional empathy is suggested to be related to effects of facial feedback in some facial manipulations but not in others.

    Altered NK1-receptor availability in patients with post traumatic stress disorder2009Inngår i: [Biological Psychiatry 2009, 65(8), Suppl. 1, 118S, no. 394], 2009, s. 118S-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background: Posttraumatic stress disorder (PTSD) is an anxiety disorder that can develop after one or more traumatic events causing extreme stress or grave physical harm. The neurokinin-1 (NK1) receptor is the primary receptor for substance P (SP); a neuropeptide suggested being involved in anxiety and depression. The present study investigated differences in NK1-receptor availability between PTSD patients and healthy controls, using positron emission tomography (PET). Methods: Eleven male refugee patients (age: 41±10) with DSM-IV defined PTSD and nine healthy male control subjects (age: 33±10) were investigated using the PET-tracer [11C]GR205171, supplied by Uppsala Imanet. GR205171 is a highly selective NK1-receptor antagonist. Scans were performed during 60 minutes in the resting state. Parametric images were generated using the graphical reference Patlak method assuming irreversible binding of [11C]GR205171 from 20-60 minutes and having cerebellum as reference region. Exploratory whole brain analyses were performed using the statistical parametric mapping (SPM2) software. Results: PTSD patients had lower [11C]GR205171 binding compared to controls, in frontal cortical clusters encompassing bilaterally insula and left Brodmann area 11, reflecting lower NK1-receptor availability. No areas were found in which PTSD patients had higher [11C]GR205171 binding. Conclusions: This is the first study reporting differences in NK1-receptor availability in PTSD patients relative to controls. A tentative conclusion is that PTSD patients have a down regulation of the NK1-receptor system, which could be either a risk factor or due to emotional trauma processing.

    Stereotypes: Suppression, Forgetting, and False Memory2003Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis presents four studies investigating (1) whether incidentally primed control-related words can attenuate the impact of activated stereotypes on subsequent evaluation of a target person, (2) the impact of motivated forgetting on the recall of stereotypically congruent and incongruent information, and (3) the impact of a directed forgetting instruction on the false recall and recognition of nonpresented stereotypical information.

    In three experiments, Study I showed that participants initially primed with the social category, immigrant, and subsequently primed with words that were evocative of control or self-control made less negative impression of a target displaying ambiguous behaviors than participants not exposed to such words.

    Study II, using a directed-forgetting paradigm, demonstrated in two experiments that participants subliminally primed with Swedish facial photographs who later studied stereotypically incongruent words roughly recalled an equal number of items regardless of the forget or remember instructions.

    Study III showed that participants primed with the social category, immigrant and then studied a list of stereotypically related and unrelated words falsely recognized more nonpresented stereotypical words when they were furnished with a forget than a remember instruction. Similarly, Study IV (Experiment 2) demonstrated that participants primed with the social category, immigrant, but not with a neutral category, falsely recalled more nonpresented stereotypical words when their cognitive capacity was depleted through a concurrent memory load task.

    The thesis presents a review and a discussion of some of the theoretical underpinnings of the extant literature on stereotyping and intergroup relations and of the social implications of the present findings.

    When tolerance leads to intolerance: accessibility effects on social judgment2009Inngår i: Scandinavian Journal of Psychology, ISSN 0036-5564, E-ISSN 1467-9450, Vol. 50, nr 4, s. 325-331Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We investigated the effects of unobtrusively primed constructs that were evocative of tolerance (e.g., tolerant, nonprejudiced) on subsequent task performances and found, contrary to our expectation, contrast effects in the judgment of an ambiguous behavioral description (Study 1 and 2). Suspecting that these results might be the outcome of social-comparison processes, in Study 3, we attempted to corroborate our findings by providing the participants with either an explicit or implicit comparison standard. The results showed that the participants who were provided with the implicit comparison standard evaluated the target behavior as more intolerant as compared to those with the explicit or no comparison standard. The results are discussed in relation to the moderating role of automatic social-comparison processes in the incidence of assimilation and contrast effects and the reduction of prejudice.

    A Model of First-responder Coping: An Approach/Avoidance Bifurcation2017Inngår i: Stress and Health, ISSN 1532-3005, E-ISSN 1532-2998, Vol. 33, nr 3, s. 223-232Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The work of first responders is fraught with numerous stressors, ranging from potentially traumatic critical incidents to institutional strains. The severity and pervasiveness of these difficulties prompt a necessary consideration of the coping methods employed by first responders. The present study developed an empirical model of first-responder coping strategies, based upon a nationally representative survey sample of 6240 first responders. Participants were drawn from Swedish first responders in the following occupations: coast guard, customs control, military, emergency medical services, fire department and police services. In the final model, exposure to stress related to well-being through several indirect paths that in sum accounted for the original direct relationship between these constructs. These several indirect paths were classified theoretically as either approach or avoidance coping behaviours or subsequent health outcomes. In general, approach coping behaviours were related to better well-being; and avoidance was related to a decrease in the outcome. The size of the present sample, as well as the diverse nature of the included first responders, suggests that the resulting model may offer a unique insight into potentially adaptive pathways for first-responder coping.

    Long-Term Posttraumatic Stress in Survivors from Disasters and Major Accidents2012Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Disasters and major accidents are a significant cause of distress worldwide. High levels of posttraumatic stress can become chronic after severe and prolonged psychological trauma, raising concerns about the extent of adverse long-term consequences after single events. The present thesis aimed to describe the course and burden of posttraumatic stress in survivors from a ferry disaster in the Baltic Sea, an airliner crash-landing in Gottröra, Sweden, and a bus accident involving Swedish 6th grade schoolchildren in Måbødalen, Norway.

    The participants were surveyed 1 month to 4 years after the events and again after 14 to 20 years. The follow-up surveys included 33 ferry disaster survivors, 70 airline survivors, and 7 surviving schoolchildren with a comparison group from the same school (n = 33). Short- and long-term changes in posttraumatic stress were estimated separately in generalised regression models refined by linear splines. In-depth interviews were conducted with 22 ferry survivors 15 years after the disaster, including structured clinical interviews and thematic analysis of survivors’ descriptions of consequences of the event and social support.

    Approximately half of all survivors experienced significant posttraumatic stress at the initial assessments. Significant long-term distress was noted in one fourth of the ferry survivors and one sixth of the airline survivors. The bus crash was not associated with significant long-term posttraumatic stress. A poorer long-term outcome was noted in women and in bereaved survivors.

    The thematic analysis revealed that long-term consequences not only included negative aspects but also positive ones, including personal growth and existential awareness. There was ample availability of social support, although the need for support extended over a period of several years. Barriers to support from significant others were described in detail by the survivors.

    The results extend previous research by providing a comprehensive account of long-term consequences of disasters and major accidents in light of early reactions. The interviews provide some new insights into features of social support that warrant further study. Important future challenges include evaluating whether timely attention to survivors at risk for chronic distress and significant others can facilitate recovery.

    Abstract [en]

    This prospective longitudinal study aimed to examine posttraumatic stress in survivors 14 years after a ferry disaster, and estimate short- and long-term changes in stress associated with traumatic bereavement and acute dissociation. There were 852 people who perished in the disaster, 137 survived. The 51 Swedish survivors were surveyed with the Impact of Event Scale-Revised (IES-R) at 3 months, 1, 3, and 14 years (response rates 82%, 65%, 51%, and 69%). Symptoms decreased from 3 months to 1 year; no change was found thereafter. After 14 years, 27% reported significant symptoms. Traumatic bereavement, but not acute dissociation, was associated with long-term symptom elevation. Chronic posttraumatic stress can persist in a minority of survivors, and traumatic bereavement appears to hinder recovery.

    Disasters yield increased rates of psychological disorders decades later. Other consequences, however, have received little attention in the past.

    Objective:

    Methods:

    A mixed-methods approach was used with 22 survivors (of 49 eligible) 15 years after a ferry disaster. Data collection included audiotaped interviews with open-ended questions and diagnostic assessment of Axis-I disorders.

    Results:

    The post-disaster incidence was 54% (12/22) for Axis-I disorders, and 45% (10/22) for full or subsyndromal posttraumatic stress disorder. Thematic analysis revealed that survivor perception of the longterm consequences included positive (character change) and negative aspects (being ascribed a survivor identity). Participants’ sought social support for several years, yet many felt hindered by experiential dissimilarity and distress of significant others.

    Conclusions:

    Axis-I disorders were prevalent, but not salient to survivors’ perceptions in the long-term. Postdisaster interventions need to attend to common barriers to support.

    Abstract [en]

    Posttraumatic stress (PTS) is common in survivors from life-threatening events. Little is known, however, about the course of PTS after life threat in the absence of collateral stressors (e.g., bereavement, social stigma, property loss) and there is a scarcity of studies about PTS in the long term. This study assessed the short- and long-term course of PTS, and the influence of gender, education and age on the level and course of PTS, in survivors from a non-fatal airliner emergency landing caused by engine failure at an altitude of 1 km. There were 129 persons on board. A survey including the Impact of Event Scale was distributed to 106 subjects after 1 month, 4 months, 14 months, and 25 months, and to 95 subjects after 19 years (response rates 64–83%). There were initially high levels of PTS. The majority of changes in PTS occurred from 1 to 4 months after the event. There were small changes from 4 to 25 months but further decrease in PTS thereafter. Female gender was associated with higher levels of PTS whereas gender was unrelated to the slope of the short- and long-term trajectories. Higher education was related to a quicker recovery although not to initial or long-term PTS. Age was not associated with PTS. The present findings suggest that a life-threatening experience without collateral stressors may produce high levels of acute posttraumatic stress, yet with a benign prognosis. The findings further implicate that gender is unrelated to trajectories of recovery in the context of highly similar exposure and few collateral stressors.

    Abstract [en]

    Background: Although road traffic accidents (RTA) are a major cause of injury and a cause of posttraumatic stress (PTS) in the aftermath, little is known about the long-term psychological effects of RTA.

    Methods: This prospective longitudinal study assessed long-term PTS, grief, and general mental health after a bus carrying 23 sixth-grade schoolchildren crashed on a school outing and 12 children died. Directly affected (i.e., children in the crash) and indirectly affected children (i.e., all pupils in the sixth grade who were not in the crash) were surveyed at 9 months (N = 102), 4 years (N = 51), and 20 years (N = 40) after the event. Psychological distresswas assessed by single items, including sadness, avoidance, intrusions, and guilt. After 20 years, PTS was assessed by the Impact of Event Scale–Revised.

    Results: Stress reactions were prevalent 9 months after the event, with sadness (69%) and avoidance (59%) being highly represented in both directly and indirectly affected groups, whereas, nightmares (60%) and feelings of guilt (50%) were only frequent in those directly affected. The frequency of sadness and avoidance decreased after 4 years in the indirectly exposed (ps < .05). After 20 years, the directly affected had a higher prevalence of PTS (p = .003), but not decreased general mental health (p = .14), than those indirectly affected.

    Conclusions: The limitations preclude assertive conclusions. Nonetheless, the findings corroborate previous studies reporting traumatic events are associated with long-term PTS, but not with decreased general mental health.

    Development and Pilot-testing of the Swedish Version of the PTSD Coach2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In Sweden, four out of five people have smartphones, indicating the potential to increase the reach of low- intensity support after trauma via smartphone-apps to aid recovery. While there are many apps in the mental health field available to the general public, their effects are rarely evaluated. The PTSD Coach smartphone-app was developed by the VA ́s National Center for PTSD—Dissemination and Training Division. A Swedish version was developed by using existing code while making adjustment to the content for a Swedish context with a view for use by both civilians and veterans. A pilot study is underway and the findings will be used to inform a larger efficacy study. To date, 31 participants have been recruited to the pilot study, in which they use the Swedish version of the PTSD Coach for four weeks. Pre- and post- assessments include a structured clinical interview (MINI), PCL-5, PHQ-9 and the Swedish version of the PTSD Coach Survey. The participants’ experiences with using the app are explored in focus groups. During this presentation, the adaptation for the Swedish PTSD Coach will be outlined and experiences from the development and pilot study of the Swedish version will be described.

    Recent randomized controlled trials of psychological interventions in healthcare: A review of their quantity, scope, and characteristics2013Inngår i: Journal of Psychosomatic Research, ISSN 0022-3999, E-ISSN 1879-1360, Vol. 75, nr 5, s. 401-408Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Objective: This study aimed to describe the quantity, scope, and fundamental characteristics of recently published randomized controlled trials (RCTs) of psychological interventions.

    Methods: We queried two major databases (PsycINFO and PubMeD) for primary reports published in 2010 of RCTs of psychological interventions for participants with a medical condition. We collected data on the characteristics of the trials, participants, interventions, outcomes, and reports.

    Results: Of 3,696 retrieved reports 295 primary publications were included. About half (53%) of trials included participants with a mental disorder and more than half evaluated interventions based on a cognitive behavioral therapy (CBT) framework. A majority of trials recruited participants in North America and Europe (79%). A minority of the trials focused on children and adolescents (17%) or the elderly (8%). The median sample size of the intervention arm was n = 41. Thirty-nine percent of trials reported solely patient-reported outcomes. Only 5% of reports indicated funding from for-profit organizations. The median 2010 impact factor of the journals in which reports were published was 2.96.

    Conclusion: This snapshot of the research on psychological interventions suggests that the evidence base for psychological interventions is expanding mainly for CBT interventions for adults in high-income countries. Although the restrictive inclusion criteria limit the generalizability of these results, researchers and funding agencies might be advised to strive for greater diversity regarding interventions, geographical/cultural settings and age groups. Regularly updated reviews of this research field, with gradually refined methodology and increased scope, may further inform funders and researchers.

    Is Social Support Equally Important for Both Directly and Indirectly Affected Disaster Victims?2011Inngår i: European Journal of Psychotraumatology: Volume 2 Supplement 1, 2011, s. 72-72Konferansepaper (Fagfellevurdert)
    Abstract [en]

    There has been much research on social support and its association with both general mental and physical health, and social support is an important salutogenic factor after traumatic events. Still, the magnitude of the effect of social support on posttraumatic stress (PTS) is not fully understood. In particular, the importance of social support after disasters may be contingent on exposure severity. In a survey of Swedish tourists 14 months after the tsunami in Southeast Asia (N4910), in which the survivors were exposed to few post-disaster adversities, detailed information on exposure severity allowed for an examination of the effect of the interaction between social support and exposure severity on PTS. Social support was assessed by the Crisis Support Scale and PTS by the Impact of Event Scale-Revised. Preliminary analyses will be presented, and the size and significance of the effect will be discussed.

    Abstract [en]

    This prospective longitudinal study aimed to examine posttraumatic stress in survivors 14 years after a ferry disaster, and estimate short- and long-term changes in stress associated with traumatic bereavement and acute dissociation. There were 852 people who perished in the disaster, 137 survived. The 51 Swedish survivors were surveyed with the Impact of Event Scale-Revised (IES-R) at 3 months, 1, 3, and 14 years (response rates 82%, 65%, 51%, and 69%). Symptoms decreased from 3 months to 1 year; no change was found thereafter. After 14 years, 27% reported significant symptoms. Traumatic bereavement, but not acute dissociation, was associated with long-term symptom elevation. Chronic posttraumatic stress can persist in a minority of survivors, and traumatic bereavement appears to hinder recovery.

    Disasters yield increased rates of psychological disorders decades later. Other consequences, however, have received little attention in the past.

    Objective:

    We aimed to examine diagnostic status and survivors’ views on disaster-related consequences and social support.

    Methods:

    A mixed-methods approach was used with 22 survivors (of 49 eligible) 15 years after a ferry disaster. Data collection included audiotaped interviews with open-ended questions and diagnostic assessment of Axis-I disorders.

    Results:

    The post-disaster incidence was 54% (12/22) for Axis-I disorders, and 45% (10/22) for full or subsyndromal posttraumatic stress disorder. Thematic analysis revealed that survivor perception of the longterm consequences included positive (character change) and negative aspects (being ascribed a survivor identity). Participants’ sought social support for several years, yet many felt hindered by experiential dissimilarity and distress of significant others.

    Conclusions:

    Axis-I disorders were prevalent, but not salient to survivors’ perceptions in the long-term. Postdisaster interventions need to attend to common barriers to support.

    Social support moderates posttraumatic stress and general distress after disaster2012Inngår i: Journal of Traumatic Stress, ISSN 0894-9867, E-ISSN 1573-6598, Vol. 25, nr 6, s. 721-727Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Social support buffers the negative impact of stressful events. Less, however, is known about the characteristics of this association in the context of disaster and findings have been discrepant regarding direct and buffering effects. This study tested whether the protective effects of social support differed across levels of exposure severity (i.e., buffered distress) and assessed whether the buffering effect differed between event-specific and general distress. Participants were 4,600 adult Swedish tourists (44% of invited; 55% women) repatriated within 3 weeks after the 2004 Indian Ocean tsunami. A survey 14 months after the disaster included the Crisis Support Scale, the Impact of Event Scale-Revised (IES-R), and the General Health Questionnaire (GHQ-12). Social support buffered the negative impact of exposure on both outcomes. The support and distress association ranged from very small in participants with low exposure to moderate in those with high exposure (ηp2 = .004 to .053). The buffering effect was not found to differ between the IES-R and GHQ-12, F(2, 4589) = 0.87, p = .42. The findings suggest that social support moderates the stressor-distress relationship after disasters. This study might help explain discrepant findings and point to refinements of postdisaster interventions.

    Prospective longitudinal long-term studies 14-20 years after three disasters2011Inngår i: European Journal of Psychotraumatology: Volume 2 Supplement 1, 2011, s. 72-72Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Although clinical experience and past research have shown that posttraumatic stress (PTS) can last for decades after a disaster, long-term follow-ups are scarce and little is known about predictors of chronic PTS. In this presentation, long-term consequences of disasters will be described by a summary of the findings from three surveys of man-made/technological disasters with 2-4 assessments during the first 34-4 years and with a long-term assessment of PTSD and general mental health after 14-20 years (Ns = 33-57). Similarities and dissimilarities in the course of PTS between the disasters will be presented. The influence of traumatic bereavement, psychological or pharmacological treatment, and additional negative life events on long-term PTS will be discussed, and experiences form conducting long-term studies will be communicated.
