Abstract

AbstractTasked with a wide variety of duties, police officers often encounter stressful situations and suffer from sleep disturbance. Previous studies have found that police officers with sleep disturbance generally reported lower levels of job satisfaction; however, the psychological mechanisms by which sleep disturbance is associated with job satisfaction are still relatively underexplored. This study investigated how sleep disturbance was associated with job satisfaction via the mediation of job involvement and via the moderation of resilience among police officers. Data from a sample of 827 Chinese police officers (86.9% men) was analysed. Participants completed a written questionnaire assessing sleep disturbance, job satisfaction, job involvement, resilience, and demographic information. A moderated mediation model was conducted to examine the research questions. Sleep disturbance was negatively associated with job involvement, which, in turn, was positively associated with job satisfaction. Furthermore, both direct and indirect effects of sleep disturbance on job satisfaction were moderated by resilience. Specifically, the negative association between sleep disturbance and job satisfaction was significant only for those with low levels of resilience, but not for those with high levels of resilience. In addition, the positive association between job involvement and job satisfaction was stronger for those with higher resilience compared with those with lower resilience. The findings advance understanding of the psychological mechanisms underlying the association between sleep disturbance and job satisfaction among police officers.
