[Associations of Work-Related Strain with Subjective Sleep Quality and Individual Daytime Sleepiness].

INTRODUCTION

Mental strain at the work place involves high potential hazard for health and quality of life. The aim of this study was to examine the relationships between strain consequences of psychological strain and subjective sleep quality as well as daytime sleepiness.

METHODS

A cross-sectional study with 84 included participants was conducted. Work-related strain consequences were evaluated by means of the 3 scales Cognitive Irritation (CI), Emotional Irritation (EI) and Global Irritation (GI) of the Irritation Scale for Assessing Work-Related Strain Consequences (IS), sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and daytime sleepiness was measured with the Epworth Sleepiness Scale (ESS).

RESULTS

Regarding the assessed socio-demographical and medical data subjects with good sleep quality did not differ from subjects with poor sleep quality. In all 3 scales of the IS and in the ESS poor sleepers reached unfavourable higher scores, but the difference with respect to the ESS was not significant. Higher scores in all 3 scales of the IS correlated with higher PSQI scores but only higher scores in the EI of the IS correlated with higher ESS scores as well.

DISCUSSION, CONCLUSIONS: Work-related strain consequences and subjective sleep quality have an interrelationship with great importance in today's world of work. Considerable aspects here are job insecurity and constant availability.
