BACKGROUND
The objective of this study was to investigate whether work unit-levels of psychosocial working conditions modify the effect of depressive symptoms on risk of long-term sickness absence (LTSA).
METHODS
A total of 5,416 Danish female eldercare workers from 309 work units were surveyed using questionnaires assessing depressive symptoms and psychosocial working conditions. LTSA was derived from a national register. We aggregated scores of psychosocial working conditions to the work unit-level and conducted multi-level Poisson regression analyses.
RESULTS
Depressive symptoms, but not psychosocial working conditions, predicted LTSA. Psychosocial working conditions did not statistically significantly modify the effect of depressive symptoms on LTSA.
CONCLUSIONS
Psychosocial working conditions did not modify the effect of depressive symptoms on LTSA. The results, however, need to be interpreted with caution, as we cannot rule out lack of exposure contrast and non-differential misclassification of the exposure.
背景
本研究旨在探讨工作单位层面的心理社会工作条件是否会改变抑郁症状对长期病假（LTSA）风险的影响。
方法
共有 309 个工作单位的 5416 名丹麦老年护理工作女性接受了抑郁症状和心理社会工作条件的问卷调查。LTSA 是从国家登记处获得的。我们将心理社会工作条件的分数汇总到工作单位层面，并进行了多层次泊松回归分析。
结果
抑郁症状而非心理社会工作条件预测了 LTSA。心理社会工作条件并没有在统计学上显著改变抑郁症状对 LTSA 的影响。
结论
心理社会工作条件并没有改变抑郁症状对 LTSA 的影响。然而，由于我们不能排除暴露对比不足和暴露的非差异错误分类，因此结果需要谨慎解释。
