Comparing treatment response between LGBQ and heterosexual individuals attending a CBT- and DBT-skills-based partial...

Despite a greater need for mental health treatment in individuals identifying as lesbian, gay, bisexual, queer, and other sexual minority identities (LGBQ+), no prior study has examined mental health treatment outcomes for LGBQ+ populations receiving standard care. We compared individuals identifying as LGBQ+ or heterosexual on treatment outcomes following a partial hospital program based on cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT).

A total of 441 participants (19% LGBQ+; mean age = 34.42 years; 56% female, 42% male, 2% nonbinary) attending a partial hospital program completed measures at admission and discharge as part of standard care. We compared LGBQ+ and heterosexual individuals on symptom outcomes (24-item Behavior and Symptom Identification Scale, 7-item Generalized Anxiety Disorder Scale, 9-item Patient Health Questionnaire), program dropout due to inpatient hospitalization, clinical global improvement, and perceived quality of care, controlling for baseline characteristics using propensity score adjustment.

Controlling for baseline demographic and clinical variables and a 10% false discovery rate, LGBQ+ and heterosexual individuals did not differ on treatment outcomes. However, when examining sexual identity subgroups, bisexual individuals reported more self-injurious and suicidal thoughts and worse perceptions of care at posttreatment compared to all other sexual identities.

Findings support the comparable effectiveness of CBT- and DBT-skills-based hospital treatment for LGBQ+ and heterosexual individuals overall but suggest specific treatment disparities for bisexual individuals. Future research is needed to establish the effectiveness of traditional evidence-based treatment in other settings and to determine whether LGBQ+ affirmative treatments for specific LGBQ+ subgroups are superior to traditional treatments.
