BACKGROUND: Work-Family Conflict (WFC) and Family-Work Conflict (FWC) are prevalent psychosocial stressors among working populations, closely associated with mental and behavioral health outcomes. However, the ways in which these conflicts relate to abnormal eating behaviors (EBS) remain insufficiently understood. Personality traits may function as psychological resources that shape individuals’ stress responses, offering a potential explanatory account. Guided by the Conservation of Resources (COR) theory, this study examined the associations between WFC, FWC, and EBS, and evaluated the independent and moderating roles of the Big Five personality traits. METHODS: A cross-sectional survey of 4579 working adults assessed WFC, FWC, EBS, and the Big Five traits (Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness). Descriptive statistics and correlation analyses were conducted. Hierarchical regression models were used to test whether WFC/FWC were associated with EBS after adjusting for the Big Five traits. To examine moderation, interaction terms were then tested for personality traits that showed significant associations with EBS in the adjusted models (agreeableness, conscientiousness, and neuroticism). All models controlled for gender, occupation, monthly household income, smoking status, and BMI. RESULTS: Both WFC and FWC were positively associated with EBS, with FWC showing a stronger association (β = 0.266, p < 0.001) than WFC (β = 0.145, p < 0.001). These associations remained significant after adjusting for the Big Five traits (WFC: β = 0.161, p < 0.001; FWC: β = 0.189, p < 0.001). In terms of personality, agreeableness and conscientiousness were inversely associated with EBS (β = -0.096 and - 0.176, both p < 0.001), whereas neuroticism was positively associated with EBS (β = 0.039, p < 0.001). Moderation analyses indicated that only the WFC × agreeableness interaction was significant (β = 0.051, p < 0.05), while other interaction terms were non-significant, suggesting a trait-specific rather than universal moderation pattern. Higher EBS scores were also observed among males, smokers, and overweight/obese individuals. CONCLUSION: This study demonstrates that work-family conflicts are robustly associated with abnormal eating behaviors, and that personality traits provide additional explanatory value in terms of independent associations and limited, trait-specific moderation. Consistent with COR theory, the findings suggest that individuals with lower agreeableness or conscientiousness and higher neuroticism may be more vulnerable to stress-related maladaptive eating. Given the cross-sectional design, these findings reflect correlational associations rather than causal effects; longitudinal research is needed to verify these relationships across cultural contexts.
