OBJECTIVE There is inconclusive evidence regarding sexual identity and race/ethnicity differences in outcomes in evidence-based psychological treatments. Although dialectical behavior therapy (DBT) is well-studied, little is known about the extent to which its efficacy generalizes to sexual minority and racial/ethnic minority people. This study examined sexual identity, race/ethnicity, and their interaction as predictors of treatment outcome and retention in DBT. METHOD Data were from five clinical trials conducted in research and community settings with a variety of adult populations (N = 269) engaged in standard DBT, augmented DBT, or DBT components. Longitudinal mixed-effects models evaluated sexual identity and racial/ethnic differences in clinical outcomes (suicide attempts, nonsuicidal self-injury [NSSI], global functioning, psychiatric hospitalizations) and retention. RESULTS Sexual identity, race/ethnicity, and their interaction did not predict the average severity or the rate of change in any clinical outcome over time. Sexual minority identity was associated with decreased risk of treatment dropout (OR = .44, p < .001). However, this effect was moderated by race/ethnicity, such that non-Hispanic White sexual minority participants had the lowest rates of dropout. Exploratory analyses suggested potential differences related to NSSI for certain sexual and racial/ethnic minority subgroups. CONCLUSIONS Findings suggest no significant differences in DBT treatment outcomes when comparing between sexual minority and heterosexual individuals and between non-Hispanic White and racial/ethnic minority individuals. Sexual minority identity interacted with race/ethnicity to predict dropout, such that non-Hispanic sexual minority people were more likely to complete DBT compared to sexual minority people of color and heterosexual individuals. Further research is needed to clarify potential subgroup and intersectional differences. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

性别认同和种族/民族作为治疗结果和辩证行为治疗保留的预测因素。

目的 关于循证心理治疗结果中的性别认同和种族/民族差异，尚无确凿的证据。尽管辩证行为疗法（DBT）已得到充分研究，但人们对其功效在多大程度上推广到性少数和种族/族裔人群却知之甚少。本研究考察了性别认同、种族/民族及其相互作用作为治疗结果和 DBT 保留的预测因素。方法 数据来自在研究和社区环境中对从事标准 DBT、增强 DBT 或 DBT 组成部分的各种成年人群 (N = 269) 进行的五项临床试验。纵向混合效应模型评估了临床结果（自杀未遂、非自杀性自伤 [NSSI]、整体功能、精神病住院治疗）和保留方面的性别认同和种族/民族差异。结果 性别认同、种族/民族及其相互作用并不能预测任何临床结果随时间的平均严重程度或变化率。性别少数群体身份与治疗退出风险降低相关（OR = .44，p < .001）。然而，这种影响受到种族/民族的影响，因此非西班牙裔白人性少数参与者的辍学率最低。探索性分析表明某些性别和种族/民族亚群体与 NSSI 相关的潜在差异。结论 研究结果表明，在性少数群体和异性恋个体之间以及非西班牙裔白人和少数种族/族裔个体之间进行比较时，DBT 治疗结果没有显着差异。性少数群体身份与种族/族裔相互作用来预测辍学，因此与有色人种和异性恋者相比，非西班牙裔性少数群体更有可能完成 DBT。需要进一步的研究来澄清潜在的亚组和交叉差异。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
