Parents randomized to receive the intervention (n=238) will be assigned to a 5-session online intervention that comprise 8-12 parents per cohort. They will register their profiles via our secure, password-protected Parents ASSIST website. Parents in the intervention arm will complete one session per week where they watch two videos focused on sexual health and family communication. They will also be asked to complete homework tasks with their GBQ child. GBQ adolescents will not be intervened upon directly; rather, we will instruct parents to engage their sons based on the information and skills learned weekly through the intervention.

Control group participants (n=238 parents) will be assigned to the health promotion arm and similarly asked to register into our secure Parents ASSIST study site but will be assigned to the control group educational resources: alcohol use, bullying, sleep hygiene, tobacco use, and body image issues. Individual participants will access via the website the videos on these non-sexual health focused conditions.

Parents ASSIST 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 the i 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 specific GBQ issues 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. 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 GBQ youth.

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)

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)

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)
