    Reliability and validity study of Persian modified version of MUSIC (musculoskeletal intervention center) - Norrtalje questionnaire2007Ingår i: BMC Musculoskeletal Disorders, ISSN 1471-2474, E-ISSN 1471-2474, Vol. 8, s. 88-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    Musculoskeletal disorders (MSDs) are a major health problem in the world. Self-reported questionnaires are a known method for estimating the prevalence of MSDs among the population. One of the studies concerning MSDs and their relation to work-related physical and psychosocial factors, as well as non-work-related factors, is the MUSIC-Norrtalje study in Sweden. In this study, the research group developed a questionnaire, which has been validated during its development process and is now considered a well-known instrument. The aim of this study is to validate the Persian version of this questionnaire.

    Methods

    The first step was to establish two expert panel groups in Iran and Sweden. The Focus Group Discussion (FGD) method was used to detect questionnaire face and content validity. To detect questionnaire reliability, we used the test-retest method.

    Results

    Except for two items, all other questions that respondents had problems with in the focus group (20 of 297), had unclear translations; the ambiguity was related to the stem of the questions and the predicted answers were clear for the participants. The concepts of 'household/spare time' and 'physical activity in the workplace' were not understood by the participants of FGD; this has been solved by adding further descriptions to these phrases in the translation. In the test-retest study, the reliability coefficient was relatively high in most items (only 5 items out of 297 had an ICC or kappa below 0.7).

    Conclusion

    The findings from the present study provide evidence that the Persian version of the MUSIC questionnaire is a reliable and valid instrument.

    Adaptation of Questionnaire Measuring Working Conditions and Health Problems Among Iranian Nursing Personnel2011Ingår i: Asian Nursing Research, ISSN 1976-1317, Vol. 5, nr 3, s. 177-182Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: To adapt a questionnaire in the Persian language measuring working conditions and health problems among nursing personnel. A further aim was to test the validity and reliability of the questionnaire. Methods: The adapted questionnaire was based on three well-established questionnaires. Physical working conditions items were from Nurse Early Exit Study. Psychosocial working conditions scales were included from Copenhagen Psychosocial Questionnaire which contains two scales on general and mental health as well. The Nordic Musculoskeletal Questionnaire was the origin of the musculoskeletal disorders questions. During the culture adaptation process, an expert panel method was used. To achieve equivalence between the sources and target version, some changes were made by the expert panel. Then the questionnaire was examined in the field for face validity and construct validity (n = 92) among Iranian nursing personnel from two hospitals. Construct validity was assessed using a priori hypothesized correlations of the outcomes with exposures. Finally the adaptation process was completed by reliability assessment using Cronbach's alpha and Intra-class Correlation Coefficient (ICC). Results: The construct validity result was the correlation of the health outcome with the work-related exposure (physical r(s) = .71 and psychosocial r(s) = .66). In the reliability assessment, Cronbach's alpha and ICC were .60 and .70 respectively. Conclusion: The findings show that the adapted questionnaire has an acceptable conceptual structure and provides reliable information from the nursing profession. Consequently, the questionnaire is applicable to work situation studies among nurses and other health care workers.

    Assessment of the Psychosocial Work Environment among Health Care Workers and Its Association with Work and Socioeconomic Status2017Ingår i: Archives of neuroscience, ISSN 2322-3944, Vol. 3, artikel-id UNSP e13576Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The health care sector constitutes one of the largest sources of employment worldwide.

    Objective: The aim of this study was to describe the psychosocial status of health care workers and its association with different covariates.

    Methods: Health care workers from different universities, hospitals, clinics, urban and rural health centers took part in this cross-sectional study. The medium version of COPSOQ was used to evaluate the association between COPSOQ and covariates. The multivariate analyses of variance and covariance were employed to determine multivariate and univariate associations between all psychosocial dimensions and covariates.

    Results: Most COPSOQ scores showed a good internal consistency and reliability, with total Cronbach’s alpha of 0.76. The study population comprised 7,027 health care workers among whom 64% were female. The results indicated that nurses are more exposed to the psychosocial work environment compared to the other groups of workers within the health care settings.

    Conclusions: Nurses had a significantly higher risk regarding almost all the psychosocial factors. Considering that the main shortage of human resources in our study population belonged to the nursing group, this bad situation is not surprising. Healthcare workers, especially nurses, are facing various psychosocial factors more than other workers are, because all these factors are in the healthcare environment at the same time.

    Effect of psychosocial factors on low back pain in industrial workers2008Ingår i: Occupational Medicine, ISSN 0962-7480, E-ISSN 1471-8405, Vol. 58, nr 5, s. 341-347Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim To test the hypothesis that workplace psychosocial factors such as demand, control, support, job satisfaction and job appreciation can predict the future onset of disabling low back pain (LBP). Methods The present study involved a prospective cohort of 4500 Iranian industrial workers. Data were gathered by means of a self-reported questionnaire about LBP, as well as working life exposure, lifestyle factors, social exposures, co-morbidity, life events and psychosomatic complaints in 2004. All new episodes of disabling LBP resulting in medically certified sick leave during the 1-year follow-up registered by occupational health clinic inside the factory. Results The participation rate was good (85%). A total of 744 subjects reported current LBP (point prevalence cases). A total of 52 (< , 2%) new episodes of disabling LBP were observed during the 1-year follow-up (incident cases). Male employees reported higher demands, lower control and lower support than female employees. Employees with high demands, low control, job strain, low job satisfaction and low job appreciation showed increased odds ratios, and these results were statistically significant. Conclusions Few prospective studies in this field have been published, but all of them are related to industrialized countries. This prospective study suggests the aetiological role of job strain for LBP. The findings of this study indicate a substantial potential for disease prevention and health promotion at the workplace.

    Sleep Quality among Health Care Workers2013Ingår i: Archives of Iranian Medicine, ISSN 1029-2977, Vol. 16, nr 2, s. 100-103Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Sleep problems are common complaints in health care workers that can affect quality of life and productivity, both in patients and healthy individuals. This study evaluates the prevalence of low sleep quality in health care workers with no health issues or complaints of sleep problems. Methods: In this cross-sectional study was conducted on healthy employees of a health care organization in Tehran. The presence of physical and mental health issues and satisfaction from their sleep quality was assessed by means of a self-administered questionnaire. Sleep quality was evaluated by the Persian version of the Pittsburgh Sleep Quality Index (PSQI). PSQI scores of 5 or less were considered as good sleep quality. Results: From 925 participants, 56.9% were good sleepers. There was a significant association between poor sleep quality and female sex, divorced, shift-working, and age; it was not associated with education level. Self-rated health (SRH) had a significant positive correlation with sleep quality. Conclusion: Poor sleep quality is common in our study population and associated with a lower SRH. The high prevalence of poor sleep quality in a group of healthy non-complaining employees can be an important early sign of underlying physical or mental health issues. Providing screening and monitoring programs to detect the underlying health conditions and their consequent treatment can promote health and productivity of employees and improve society's health, both directly and indirectly.

    Reliability and validity of Persian version of World Health Organization health and work performance questionnaire in Iranian health care workers2012Ingår i: The international journal of occupational and environmental medicine, ISSN 2008-6520, Vol. 3, nr 1, s. 33-38Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND:

    The effect of health status on productivity has widely been studied and discussed in literature. Valid and reliable tools are needed to evaluate the levels of health and productivity and provide detailed information, before any intervention is implemented. World Health Organization Health and Work Performance Questionnaire (HPQ) is a widely used instrument in estimating the workplace costs of health problems in terms of reduced job performance, sickness absence, and work-related accidents and injuries.

    OBJECTIVE:

    To assess the reliability and validity of Persian version of HPQ in Iranian health care workers.

    METHODS:

    The questionnaire was translated to Persian and back translated. 102 health care workers completed the questionnaire. Absence and sick-leave data was extracted from administrative records.

    RESULTS:

    Factor analysis revealed acceptable validity for the questionnaire in part A (health). Cronbach's alpha was >0.73 for all scales of Parts B (work) and C (demographic). Questions targeting days of absence and sick-leave had acceptable correlation with administrative records (Pearson's r >0.75), while questions on total hours worked showed lower correlation.

    CONCLUSION:

    Persian version of HPQ can be considered a reliable and valid tool in Iranian health workers.
