Impact of working hours on depressive symptoms in working population:The mediating role of internet use
摘要
Abstract
[Background]In the context of China's rapid economic growth and social acceleration,long working hours are emerging as a key factor affecting well-being and contributing to depression. [Objective]To examine the longitudinal interaction between working hours and depressive symptoms,and evaluate potential mediating role of internet use in the relationship between working hours and depressive symptoms. [Method]This study utilized two waves of panel data from the China Family Panel Studies(CFPS)collected between 2016 and 2018.It constructed a longitudinal sample of 4900 individuals aged 18-70 years who were employed with known working hours across various occupations.Based on survey data and the Center for Epidemiologic Studies Depression Scale(CES-D),we measured and compared working hours,internet use,and depressive symptoms.Pearson correlation analysis was employed to examine the associations among key variables.Through cross-lagged panel models and a semi-longitudinal mediation model,we examined the bidirectional interactive mechanisms between working hours and depressive symptoms,with a particular focus on revealing the mediating pathways of internet use and any group heterogeneity. [Result]The study sample comprised 4900 participants,aged 18 to 70 years.Of these,43.8%were male,and 77.35%were married.In 2016,the average working hours were(48.55±22.17)h,and over half of the participants used the internet(59.84%).The average score on the depressive symptoms scale was(5.11±3.78).The cross-lagged panel models revealed a dynamic interplay between working hours,internet use,and depressive symptoms.Specifically,working hours,internet use,and depressive symptoms in 2016 all positively predicted their respective counterparts in 2018.Furthermore,working hours in 2016 positively predicted internet use in 2018(β=0.045,P<0.001)and depressive symptoms in 2018(β=0.027,P<0.05),indicating that longer working hours were associated with an increased likelihood of internet use and worsened depressive symptoms.The half-longitudinal mediation models demonstrated a significant medi-ating effect of internet use in the relationship between working hours and depressive symptoms(effect size=-0.0013,P<0.05),suggesting that internet use may buffer the adverse effects of long working hours on depressive symptoms.The subgroup analyses of the half-longi-tudinal mediation model revealed significant mediation effects of internet use within the female and married female subgroups,as well as significant mediating pathways within the older adult and employment stability subgroups.The Panel Logit regression results indicated that internet use(high or low)was associated with a lower risk of depressive symptoms compared to non-internet use,positioning internet use as a protective factor against depressive symptoms symptoms among younger adults,those with stable employment,and married women. [Conclusion]This study confirms that prolonged working hours are detrimental to psychological health.Internet use mediates the rela-tionship between working hours and depressive symptoms,effectively mitigating the psychological harm of long working hours.This me-diating effect is particularly pronounced for women,especially married women.关键词
