Police Officers'Work-Family Support Profiles and Its Association with Negative Emotions:Mediating Effect of Psychological Capital
摘要
Abstract
This study examined a cohort of 935 police officers in a city in Zhejiang Province using the short-form Depression Anxiety Stress Scales(DASS-21),the Work-Family Support Scale,and the Psychological Capital Questionnaire.Latent profile analysis(LPA)was employed to identify distinct patterns of work-family support among participants.We further investigated the associations between latent classes of work-family support and negative emotions,and explored the potential mediating role of psychological capital in the relationship.The results revealed that 1)LPA identified six subgroups of perceived work-family support(Entropy=0.89,LMR p=0.05,BLRT p<0.001):low support(5.03%),moderate support(20.43%),moderately high support(43.00%),work-dominant support(5.24%),family-dominant support(7.81%),and high support(18.50%).2)Higher levels of work-family support were significantly associated with lower levels of negative emotions(depression,anxiety,and stress).3)Using the low-support group as the reference,psychological capital significantly mediated the relationship between work-family support and negative emotions.关键词
