An Identity-Affirming Web Application to Help Sexual and Gender Minority Youth Cope With Minority Stress: Pilot Randomized Controlled Trial

BACKGROUND: Efficacious mental health interventions for sexual and gender minority youth have had limited reach, given their delivery as time-intensive, in-person sessions. Internet-based interventions may facilitate reach to sexual and gender minority youth; however, there is little research examining their efficacy. OBJECTIVE: This study aims to describe the results of a pilot randomized controlled trial of imi, a web application designed to improve mental health by supporting lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority identity affirmation, coping self-efficacy, and coping skill practice. METHODS: Sexual and gender minority youth (N=270) aged 13 to 19 (mean 16.5, SD 1.5) years and living in the United States were recruited through Instagram advertisements. Approximately 78% (210/270) of the sample identified as racial or ethnic minorities. Participants were randomized in a 1:1 fashion to the full imi intervention web application (treatment; 135/270, 50%) or a resource page-only version of the imi site (control; 135/270, 50%). The imi application covered four topical areas: gender identity; lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority identity; stress and coping; and internalized homophobia and transphobia. Participants explored these areas by engaging with informational resources, exercises, and peer stories at a self-guided pace. Both arms were assessed via web-based surveys at baseline and 4-week follow-up for intervention satisfaction, stress appraisals (ie, challenge, threat, and resource), coping skills (ie, instrumental support, positive reframing, and planning), and mental health symptoms among other outcomes. Main intent-to-treat analyses compared the arms at week 4, controlling for baseline values on each outcome. The treatment arm showed significantly greater improvement in challenge appraisals (ie, belief in one's coping abilities) than the control (Cohen d=0.26; P=.008). There were no differences between the arms for threat (d=0.10; P=.37) or resource (d=0.15; P=.14) appraisals. The treatment arm showed greater increases in coping skills than the control arm (instrumental support: d=0.24, P=.005; positive reframing: d=0.27, P=.02; planning: d=0.26, P=.02). Mental health symptoms improved across both the treatment and control arms; however, there were no differences between arms. Within the treatment arm, higher engagement with imi (≥5 sessions, >10 minutes, or >10 pages) predicted greater improvement in stress appraisals (all P values <.05). CONCLUSIONS: The results provide initial evidence that asynchronous psychosocial interventions delivered via a web application to sexual and gender minority youth can support their ability to cope with minority stress. Further research is needed to examine the long-term effects of the imi application. TRIAL REGISTRATION: ClinicalTrials.gov NCT05061966; https://clinicaltrials.gov/ct2/show/NCT05061966.
