This cross-sectional study investigated the relationships between job stress, psychological adaptation, negative affective states and IGD among 1805 factory workers recruited by stratified multi-stage sampling between October and December 2019. Structural equation modeling was conducted to test the proposed mediation model. Among the participants, 67.3% were male and 71.7% were aged 35 years old or below. The prevalence of probable depression, probable anxiety, and IGD was 39.3%, 28.7%, and 7.5%. Being male, younger age, and shorter duration of living in Shenzhen were associated with higher IGD scores. Job stress was significantly associated with IGD (β=.11, p=.01) but not with negative affective states (β=.01, p=.77). Psychological adaptation was significantly associated with negative affective states (β=-.37, p<.001) but not with IGD (β=.09, p>.05). Negative affective states were positively associated with IGD (β=.27, p<.001). The indirect effect of psychological adaptation (β=-.10, p=.004) but not job stress (β=.003, p=.77) on IGD through negative affective states was statistically significant. The observed psychological correlates and mechanisms are modifiable, and can inform the design of evidence-based prevention programs for depression, anxiety, and IGD in this population.
