Stigma-related stress and inflated perceptions of substance use norms are positioned in the literature as theoretically distinct explanations for disproportionate substance use among sexual minorities. As research has yet to examine how these variables may interact in an intervention context, this study examined the impact of recent experiences with violence and harassment due to sexual minority status (i.e., interpersonal stigma exposure) on the effectiveness of a culturally adapted personalized normative feedback intervention for lesbian, bisexual, and queer (LBQ) women. A sub-sample of 499 moderate-to-heavy drinking LBQ women were randomized to receive personalized normative feedback (PNF) on alcohol use or control topics within a broader digital competition designed to challenge negative LBQ stereotypes. At baseline, recent interpersonal stigma exposure strengthened the relationship between perceived LBQ alcohol-related norms and participants’ own alcohol-related behaviors (i.e., consumption and consequences). At follow-up, 3 months later, recent interpersonal stigma exposure moderated the effectiveness of alcohol PNF with substantially less drinking and consequences among participants in the treatment condition reporting recent violence or harassment due to sexual minority status, relative to those reporting no such experiences. Underscoring the utility of PNF for LBQ women and potentially other heavy drinking stigmatized populations, findings suggest that a greater tendency to conform to over-estimated ingroup drinking norms may be another way in which minority status-based violence and harassment contributes to alcohol consumption in stigmatized populations.

与耻辱相关的压力和对物质使用规范的夸大看法在文献中被定位为对性少数群体中不成比例的物质使用的理论上不同的解释。由于研究尚未检验这些变量在干预环境中如何相互作用，本研究检验了最近因性少数身份（即人际污名暴露）而遭受暴力和骚扰的经历对适应文化的个性化规范反馈有效性的影响对女同性恋、双性恋和酷儿 (LBQ) 女性的干预。499 名中度至重度饮酒 LBQ 女性的子样本被随机分配，以在旨在挑战负面 LBQ 刻板印象的更广泛的数字竞赛中接受关于酒精使用或控制主题的个性化规范反馈 (PNF)。在基线，最近的人际污名暴露加强了感知到的 LBQ 酒精相关规范与参与者自身的酒精相关行为（即消费和后果）之间的关系。在 3 个月后的随访中，最近的人际间污名暴露降低了酒精 PNF 的有效性，与那些报告没有此类经历的人相比，在报告最近因性少数身份而遭受暴力或骚扰的治疗条件参与者中，饮酒和后果显着减少。强调 PNF 对 LBQ 女性和其他潜在的重度饮酒耻辱人群的效用，
