[Impact of work place stresses on work ability index in patients with depressive disorders].

INTRODUCTION

Depression seriously affects one's ability to perform work tasks and function at work. We studied the impact of both the individual and work factors on work ability index in patients suffering from depression.

MATERIAL AND METHODS

The prospective study, which was conducted by using questionnaires, included 210 patients with depression, who had been on sick leave from 60 to 360 days. The individual factors were evaluated by the standardized abridged form of Occupational Stress Questionnaire, while the work place factors in relation to work ability were evaluated by the work ability index.

RESULTS

Poor work ability was observed in 151 (71%) of subjects suffering from depression. All workplace stresses, lack of support by colleagues and supervisors, ergonomically not adjusted work and huge work load are statistically associated with poor work ability index (P=0.001). More than 95% of variables of the evaluated work ability index are the result of varying in the group of stresses at work place (R2=0.95). Perception of bad health condition (Rsq=0.412, P=0.001), low level of life satisfaction (Rsq=0.309, P=0.001), low level of motivation and work knowledge (Rsq=0.309, P=0.001) are predictors for poor work ability. The work ability cannot be related with age and sex.

CONCLUSION

The key activities for maintaining the work ability at the times when epidemic of depression emerges, as it is nowadays, are timely carrying out the psycho-treatments, mental and professional rehabilitation, occupational therapy and adapted work place.
