<p>This engagement award project evaluated the preliminary effectiveness of a culturally tailored psychoeducation session aimed at reducing mental health stigma among African American women and their social support networks.&#xa0;Participants included 25 community members, including African American women of reproductive age and members of their social support networks, engaged in a two-hour psychoeducation group session. This session addressed perinatal mood disorders, cultural and historical factors contributing to mental health stigma, impacts of untreated conditions, and culturally appropriate resources. Participants completed the Stigmatized Attitudes Toward Mental Illness Scale (SATMIS) before and after the psychoeducation session, along with a satisfaction questionnaire.&#xa0;Analysis revealed a large (Cohen’s <i>d</i> = 0.98), significant reduction in stigmatized attitudes toward mental illness from pre-session (<i>M</i> = 62.4, <i>SD</i> = 10.2) to post-session (<i>M</i> = 48.9, <i>SD</i> = 9.7; <i>p</i> &lt; .001). Most (92%) participants reported high satisfaction with the psychoeducation session.&#xa0;This engagement project provides preliminary evidence that a brief, culturally tailored psychoeducation group session can effectively reduce mental health stigma among African American women and their support networks. Given the disproportionate burden of perinatal mood and anxiety disorder (PMADs) and maternal mortality among African American women, this approach shows potential for addressing a significant barrier to mental health care utilization in this population.</p>
