Research in help seeking has identified parent-child communication and self-stigma of seeking help as significant predictors. However, much of the research surrounding help seeking has focused on help-seeking attitude or intention, rather than actual help-seeking behavior. To address the gap in literature, the purpose of the present study was to examine the direct effect of parent-adolescent communication regarding mental health issues on actual help-seeking behaviors of young adults as well as exploring its indirect effect through self-stigma of seeking help. Additionally, we examined whether perceived support from peers would moderate the link between parent-adolescent communication on mental health issues and actual help seeking behaviors. Participants included 531 emerging adults from the Southwest U.S. who completed the research questionnaires with selected instruments assessing variables of interest. The results supported a significant indirect effect, b = .034, 95%CI [.012, .061]. Specifically, findings indicated that parent-adolescent communication on mental health issues significantly predicted self-stigma of self-seeking, b = -.159, t = -3.545, p < .001, 95%CI [-.247, -.071], and that both self-stigma (b = -.212, t = -4.313, p < .001, 95%CI [-.308, -.115]) and parent-adolescent communication (b = -.216, t = -4.221, p < .001, 95%CI [-.317, -.116]) were significant predictors for actual help-seeking behavior in the final model. However, the moderator effect was not supported (b = .087, t = 1.126, p = .261, 95%CI [-.065, .238]). Drawing from these findings, a tentative conclusion is that when participants have had better communication with parents regarding mental health issues during adolescence, they are more likely to engage in actual help-seeking behaviors as young adults and that this influence can be explained by participants' lower self-stigma of seeking help. Future research directions, limitations, and clinical implications of the study will be elaborated in the presentation.
