Objectives: Caregiving does not have to be a totally negative experience for the husband caregivers of breast cancer survivors (BCS). There are growing interests in exploring the positive psychological changes (aka posttraumatic growth; PTG) among husbands of BCS. Western studies have shown that coping resources, cognitive appraisal, and coping strategies are associated with PTG among caregivers of BCS. Studies in the Chinese context are limited. This study examined the psychosocial correlates of PTG among husbands of Chinese BCS. Methods: Husbands of Chinese BCS (N = 176) were recruited from two hospitals in Weifang, China to complete a cross-sectional survey. Their levels of caregiving burden, marital satisfaction, cognitive appraisals, coping strategies, and PTG were measured. Results: After controlling for covariates, hierarchical regression results indicated that higher caregiving burden (β = .29), marital satisfaction (β = .27), challenge appraisal (β = 016), and social support seeking (β = .23) were associated with higher PTG (Ps < .05). Additionally, a significant interaction between caregiving burden and positive reframing emerged in explaining PTG (β = .17, P < .05). Positive reframing was only associated with higher PTG among those with higher caregiving burden (β = .25, P = .03), but not those with lower caregiving burden (β = −.09, P > .05). Conclusions: Stress and coping variables significantly contributed to PTG among husbands of Chinese BCS. Our findings implied that addressing those husband caregivers' marital satisfaction, challenge appraisal toward the impact of breast cancer, and social support seeking could be intervention strategies to facilitate their PTG. Among husbands having higher caregiving burden, positive reframing may also facilitate their PTG.
