Exploring Mechanisms of Mental Illness Stigma Reduction in Asian Canadian Men.

Objective: Although there is evidence of effective stigma reduction by various psychological and educational interventions, the mechanisms of change remain unclear. In this article, we examine hypothesized processes that might have mediated reductions in stigma observed among Asian men who had received in mental health promotion interventions in Greater Toronto Area, Canada. Method: Our sample consisted of 495 Asian men, who received either acceptance and commitment therapy (ACT; n = 133), contact-based empowerment education (CEE; n = 149), combination of ACT and CEE (n = 152), or psychoeducation (n = 61). Group differences on intervention outcomes, including stigmatizing attitudes (Community Attitudes toward the Mentally Ill), internalized stigma (Internalized Stigma of Mental Illness), valued living (Valued Living Questionnaire), and attitudes to engage in social change (Social Justice Scale) were hypothesized to be due to the impact of the different interventions and mediated by changes in specific underlying psychological processes. These process-related changes were modelled using measures of mindfulness (Freiburg Mindfulness Inventory), psychological flexibility (Acceptance and Action Questionnaire version II), and empowerment (Empowerment Scale [ES]). Their pre- and post changes were analyzed with repeated measures analysis of variance, and mediational analyses were performed. Results: Findings from mediational analyses suggest that empowerment (ES) mediated a significant portion of the effects observed in reduction in stigmatizing attitudes and internalized stigma across intervention groups (t = 3.67 to 3.78 for CEE groups, and t = 4.32 to 4.56 for ACT groups). For the ACT groups, reduction in internalized stigma might also have been partly mediated by psychological flexibility, an intervention-specific psychological process. Conclusions: Results from the current study suggest that different stigma reduction interventions may be mediated by increased empowerment as a common mechanism of change, while intervention-specific mechanism of change, improved psychological flexibility through ACT, may also contribute to improvement in internalized stigma.
