An interventional study of The Gender Inclusive Sexuality Talks Program and GIST Control in HIV/STI Incidence and Communication About Health Information, sponsored by University of Pennsylvania. Recruiting at 1 site in United States. Open to participants aged 12 Years to 100 Years. Per ClinicalTrials.gov, last updated 2026-09-17.

The study is centered on helping parents answer and meet the sexuality-specific questions and needs of transgender, gender diverse, lesbian or bisexual female youth. This study seeks to test the efficacy of the GIST Program as a parent-child sexuality communication intervention that educates and trains parents to be purveyors of inclusive health information as transgender, gender diverse, lesbian or bisexual female youth come of age at home.
Parental acceptance after youth come out as transgender, gender diverse, lesbian or bisexual is a protective factor for the health of this youth group; however, parents lack support in initiating and sustaining sexuality discussions inclusive of their teens' attractions, behaviors and identities. Thus, in the absence of skills and supports, adolescents' and parents' mental health, health behaviors and overall family functioning tend to be negatively impacted after sons come out as gay or bisexual. The overall objective of this study is to test the efficacy of the GIST Program (Gender Inclusive Sexuality Talks), a sexuality communication intervention for parents, after youth disclose transgender, gender diverse, lesbian or bisexual identities.
We will conduct a randomized controlled trial with parent and youth dyads (N=300) to establish the efficacy of the GIST Program as a hybrid 5-session online intervention that educates parents about germane sexuality-specific topics and provide communication skills for family discussions. Our Specific Aims are to (1) determine whether the GIST Program enhances parent-adolescent sexuality communication quality (e.g. parent- and child-reported comfort) and quantity (e.g. frequency and range of topics discussed) compared to the control group, (2) establish whether the GIST Program results in decreases in mental health symptomology (e.g. depressive and anxiety symptoms) among parents and youth, increases dyadic health behavior (e.g. accessing preventive health services, health screening behaviors), and improves family functioning (e.g. affective response, communication, general functioning) over 12 months of follow-up, and (3) examine how theory-based variables (e.g. attitudes and norms, self-efficacy and intentions to discuss sexuality with transgender, gender diverse, lesbian or bisexual child) mediate the intervention effects on adolescent and parent mental health, parent-adolescent health behavior and family functioning over time.

Parents randomized to this arm will receive five, online based group sessions.
Behavioral: The Gender Inclusive Sexuality Talks Program
Parents randomized to this arm will have individual access to an online series of five modules that they can complete at their own pace. The content for each module are LGBTQ-specific health issues such as sleep hygiene, bullying, tobacco and alcohol use, and body image concerns.
Behavioral: GIST Control
The GIST Program is a 5-session intervention where an interventionist will facilitate sessions that will include 8-12 parents per group. Each parent will have access to intervention content (e.g., videos, activities) across five synchronous sessions. Session I will focus on the issue of coming out and its impact on the family as well as on youth mental health. Session II centers on communication-based content. Sessions III and IV focuses on topic-centered content to address the knowledge gap parents have reported regarding general LGBTQ concerns and builds on the communication skills learned in Session I. Session V provides a communication recap and focuses on how parents may have follow-up conversations with healthcare providers. In between the sessions, asynchronous interactive homework assignments will be provided to review concepts learned in the previous sessions and to initiate joint activities between parents and youth.
The control arm consists of access to five online modules. Parents in this condition will be able to view video content focused on health issues germane for LGBTQ youth that are not focused on sexual health. These outcomes are on bullying, alcohol and tobacco use, sleep hygiene and body image concerns.
Parent-Adolescent Communication Quantity
The Parent- Teen Sexual Risk Communication Topic Scale will be adopted and used to measure the quantity of topics discussed. Participants are asked if they had ever discussed the topics with their child/parent, and if so, which ones. To measure quantity, sample questions would be "To what extent have you ever discussed any of the following topics with your mother/father?" Sample items: coming out/disclosure of sexual orientation, using a condom, peer pressure and sexual pressure from dating partners, penilevaginal or other types of intercourse. Response options: (1) none, (2) a little, (3) some, (4) a lot, or (5) extensive. (8 items; alpha = .85-.95)
Time frame: Baseline, 1 week, 3 months, 6 months
Parent-Adolescent Communication Quality
The quality of sexuality-sensitive communication will be determined using the Family Sexuality Communication Quotient - a measure of a general family orientation to discussion about sexuality between parents and children; this is an 18-item scale with options (1-Strongly Agree to 5-Strongly Disagree). The first subscale on comfort measures the perceived degree of openness with which sexuality is discussed in the family (e.g., I feel free to ask my parents questions about sexuality). The second subscale on information measures perception of the amount of information learned and shared during discussions (e.g., I feel better informed about sexuality if I talk to my parents.) (18 items; alpha = .91)
Time frame: Baseline, 1 week, 3 months, 6 months
Adolescent and Parent Mental Health (Depression)
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression. In addition to making criteria-based diagnoses of depressive disorders, the PHQ-9 is also a reliable and valid measure of depression severity. These characteristics plus its brevity make the PHQ-9 a useful clinical and research tool. This 9-item questionnaire lists varying depression symptoms and inquires about how much each depression symptom has been noted as bothersome within the past two weeks. Response options are: (0) not at all, (1) several days a week, (2) more than half the days, (3) nearly every day. (9 items; alpha = .95)
Time frame: Baseline, 1 week, 3 months, 6 months
Adolescent and Parent Mental Health (Anxiety)
The GAD-7 is a valid and efficient tool for screening for Generalized Anxiety Disorder and assessing its severity in clinical practice and research. There was good agreement between self-report and interviewer-administered versions of the scale. This 7-item questionnaire lists varying anxiety symptoms and inquires about how much each symptom has been noted as bothersome within the past two weeks. Response options are: (0) not at all, (1) several days a week, (2) more than half the days, (3) nearly every day. (7 items; alpha = .92)
Time frame: Baseline, 1 week, 3 months, 6 months
Parent-Adolescent Health Behavior (Wellness Appointment)
We will measure successful setting up by both parent and child of screening appointments with an LGBTQ-competent provider during each follow-up survey. Three questions will asked: (1) Since the last survey, have you and your parent/child looked up LGBTQ-friendly health providers in your area? (Yes/No); (2) Since the last survey, have you and your parent/child made an appointment for a wellness appointment? (Yes/No); and (3) Since the last survey, have you and your parent/child seek out a healthcare provider to be screened for a sexually-transmitted infection? (Yes/No).
Time frame: Baseline, 1 week, 3 months, 6 months
Family Functioning
The Family Assessment Device (FAD) is based on the McMaster Model of Family Functioning (MMFF), a clinically oriented conceptualization of families. It is a screening instrument consisting of 60-items. The model identifies seven dimensions of family functioning and this study will use the questions from three subscales (affective response, communication and general functioning). Response categories are as follows: strongly agree, agree, disagree, and strongly disagree. Scores range from 1 to 4 with 1 reflecting healthy functioning and 4 reflecting unhealthy functioning. (24 items; alpha = .92)
Time frame: Baseline, 1 week, 3 months, 6 months
