Affirmative Family and Individual Psychotherapy for Sexual and Gender Minority Adults and Their Nonaccepting Parents

January 12, 2026 updated by: Yale University
The purpose of this study is to assess the efficacy of an LGBTQ-affirmative individual cognitive behavioral psychotherapy (CBT) and LGBTQ-affirmative family therapy (attachment-based family therapy for sexual and gender minority young adults; ABFT-SGM) delivered via telehealth to a sample of sexual and gender minority adults with nonaccepting parent(s) in New York, Pennsylvania, Connecticut, and Israel. The investigators will assess whether both treatments are associated with significant decreases in depressive and anxiety symptoms. The investigators will also assess whether and how each treatment achieves reductions in mental health symptoms through specific mechanisms (e.g., rejection sensitivity, internalized stigma, emotion dysregulation, parental rejection and acceptance).

Study Overview

Detailed Description

The purpose of this study is to assess the efficacy and purported change mechanisms in an LGBTQ-affirmative individual cognitive behavioral psychotherapy (CBT) and LGBTQ-affirmative family therapy (attachment-based family therapy for sexual and gender minority young adults; ABFT-SGM) delivered via telehealth to a sample of sexual and gender minority adults in New York, Pennsylvania, Connecticut, and Israel. In this 2-arm randomized clinical trial (RCT), participants will receive 16 weekly sessions of either LGBTQ-affirmative CBT or ABFT-SGM. Investigators will assess whether both treatments are associated with significant decreases in depressive and anxiety symptoms. Investigators will also assess whether psychosocial mechanisms (e.g., rejection sensitivity, internalized stigma, emotion dysregulation, parental rejection and acceptance) mediate reductions in psychological symptoms, and whether such mediators differ between the two treatments. Finally, investigators will assess whether participants who begin treatment with higher levels of parental rejection benefit more from ABFT-SGM than from LGBTQ-affirmative CBT, and whether participants with higher initial levels of maladaptive stress responses benefit more from LGBTQ-affirmative CBT.

  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: LGBTQ-affirmative CBT
Individuals assigned to LGBTQ-affirmative cognitive behavioral therapy will receive 16 weekly individually-delivered sessions, directly after baseline assessment, delivered via telehealth. Based on the Unified Protocol, sessions will address minority stress mechanisms underlying sexual and gender minority mental health disparities.
16-session LGBTQ-affirmative psychotherapy using cognitive behavioral techniques
Experimental: ABFT-SGM
Individuals assigned to attachment-based family therapy for sexual and gender minorities will receive a 16-session sequence of family-based therapy delivered via telehealth. This sequence will include sessions with sexual and/or gender minority adult children alone, adult children and parent(s), and parent(s) alone. Sessions will address the quality parent-child relationship in relation to child sexual orientation and gender identity to target mental health disparities.
16-session attachment-based family therapy for sexual and gender minority young adults and their nonaccepting parents

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in depression symptoms
Time Frame: Baseline, Immediate Post-intervention, 5-month Post-intervention
Depressive symptoms will be measured using the 21-item Beck Depression Inventory-II (BDI). Items are rated on a scale from 0-3 where higher scores indicate greater depression symptoms, with a maximum score of 63.
Baseline, Immediate Post-intervention, 5-month Post-intervention
Change in anxiety symptoms
Time Frame: Baseline, Immediate Post-intervention, 5-month Post-intervention
Anxiety symptoms will be measured using the 21-item Beck Anxiety Inventory (BAI). Items are rated on a scale from 0-3 where higher scores indicate greater anxiety symptoms, with a maximum score of 63.
Baseline, Immediate Post-intervention, 5-month Post-intervention

Secondary Outcome Measures

Measure Description
Time Frame
Change in emotion dysregulation
Time Frame: Baseline, Immediate Post-intervention, 5-month Post-intervention

Items are rated on a 5-point scale from 1-5; items 1, 4, and 6 are reverse coded. Items are averaged for a total maximum score of 5, where higher scores indicate higher emotion dysregulation.
Baseline, Immediate Post-intervention, 5-month Post-intervention
Change in implicit sexual orientation bias
