Alcohol consumption is prevalent in Chinese culture and alcohol-related problems are a considerable social issue in China. Exposure to potentially traumatic events may increase the risk of alcohol-related problems. Social support often buffers this exposure. This study examined the relationship between trauma exposure and alcohol misuse and explored whether social support moderated this relationship. Data were collected through a face-to-face interviews with a stratified cluster sample of 692 Chinese adults living in Guangzhou, China. The Life Events Checklist-5 measured trauma exposure, the AUDIT was used to examine problematic alcohol use and the social support rating scale measured subjective and objective social support. Spearman correlation results indicated that trauma exposure (rs=.15) perceived family support (rs=-11) and perceived friend support (rs=.15, p<.01) were associated with alcohol misuse. Negative binomial regression models adjusting for potential confounds, demonstrated that trauma exposure remained associated with alcohol misuse, but social support did not modify this relationship.
