Fatigue and psychosocial distress in the working population. Psychometrics, prevalence and correlates.

Objective: The purposes of this study were: (1) to explore the relationship between fatigue and psychological distress in the working population; (2) to examine associations with demographic and health factors; and (3) to determine the prevalence of fatigue and psychological distress. Methods: Data were taken from 12,095 employees. Fatigue was measured with the Checklist Individual Strength, and the General Health Questionnaire (GHQ) was used to measure psychological distress. Results: Fatigue was fairly well associated with psychological distress. A separation between fatigue items and GHQ items was shown. No clear, distinct pattern of associations was found for fatigue vs. psychological distress with respect to demographic factors. The prevalence was 22% for fatigue and 23% for psychological distress. Of the employees reporting fatigue, 43% had fatigue only, whereas 57% had fatigue and psychological distress. Conclusions: The results indicate that fatigue and psychological distress are common in the working population. Although closely associated, there is some evidence suggesting that fatigue and psychological distress are different conditions, which can be measured independently

Lifestyle Factors as Risk Factors for Fatigue and Psychological Distress in the Working Population. Prospective Results From the Maastricht Cohort Study.

We examined potentially modifiable lifestyle factors as possible risk factors for the onset of fatigue and psychological distress after 1-year follow-up among 8833 employees who participated in the prospective Maastricht Cohort Study of "Fatigue at Work." Results showed, even after adjustment for demographics, presence of disease, other lifestyle factors, psychosocial work characteristics, and psychological distress, that overweight (body mass index, 25 to 29.9) and being physically inactive during leisure time were strongly related to onset of fatigue in men, whereas underweight (body mass index, < 18.5) in women increased the risk for future fatigue. In addition, the study suggests some differential effects of lifestyle factors in the onset of psychological distress. Certainly, these modifiable factors can be targeted in interventions, either on an individual or group level, to prevent or at least reduce the risk of developing fatigue and psychological distress in the working population

Psychosocial work characteristics as risk factors for the onset of fatigue and psychosocial distress: prospective results from the Maastricht Cohort Study.

Background. Prolonged fatigue has recently attracted attention in occupational (mental) health research since it may lead to sickness absenteeism and work disability. To date, little is known about the role of psychosocial work characteristics in the aetiology of fatigue. In this study we examined prospectively a wide range of psychosocial work characteristics as possible risk factors for the onset of fatigue and psychological distress in the working population. Methods. This study is based on 8833 employees, participating in the Maastricht Cohort Study of 'Fatigue at Work'. A wide range of psychosocial work characteristics, measured at baseline, was used to predict the onset of fatigue and psychological distress I year later. Fatigue was measured with the Checklist Individual Strength; the General Health Questionnaire was used to measure psychological distress. Results. The cumulative incidence of fatigue during 1 year follow-up was 9(.)7% (N = 492) in men, and 13(.)5% (N = 241) in women. Psychological demands at work as well as physical and emotional demands increased the risk for fatigue in men, whereas decision latitude in men and co-worker social support in women were protective against fatigue. These prospective associations remained significant after adjustments for potential confounders and baseline fatigue. As regards psychological distress, no association was found with decision latitude, while conflicts at work increased the risk of psychological distress. Conclusions. Psychosocial work characteristics were significant predictors for the onset of fatigue in the working population. The prospective associations suggest some differential effects in the aetiology of fatigue and psychological distress. Good interpersonal relationships at work and high decision authority were demonstrated to be relevant aspects that should be targeted for prevention

Development of the chronic fatigue syndrome in severely fatigued employees: predictors of outcome in the Maastricht cohort study.

Contains fulltext : 58321.pdf (publisher's version ) (Closed access)STUDY OBJECTIVE: To identify risk factors of the development of the chronic fatigue syndrome (CFS), the persistence or recurrence of fatigue, or recovery from fatigue in a large sample of fatigued employees. DESIGN: Analyses were based on the Maastricht cohort study (MCS), a prospective population based cohort study among more than 12 000 employees. Multiple regression models were used to identify predictors of CFS-like caseness (meeting research criteria for CFS), non-CFS fatigue caseness, or no fatigue caseness. SETTING: The working population in the Netherlands. PARTICIPANTS: 1143 employees with medically unexplained fatigue were followed up prospectively for 44 months. MAIN RESULTS: At 44 month follow up, 8% of the employees were CFS-like cases (none of who reported to have received a CFS diagnosis), 40% were non-CFS fatigue cases, and 52% were no longer fatigue cases. Factors that predicted CFS-like caseness compared with non-CFS fatigue caseness were high age, exhaustion, female sex, low education, and visits to the general practitioner. Factors that predicted CFS-like caseness compared with no fatigue caseness were fatigue, exhaustion, low education, visits to the GP and occupational physician, and bad self rated health. Factors that predicted non-CFS fatigue caseness compared with no fatigue caseness were fatigue, low self perceived activity, exhaustion, anxious mood, and bad self rated health. CONCLUSIONS: Unexplained fatigue among employees in some instances is a precursor of the development of CFS. The prognostic role of self rated health suggests that prevention and treatment of chronic fatigue should be aimed at changing the perception of health or illness. Less clear is the role of health care seeking or receiving a CFS diagnosis
