Abstract: Background Adolescent mental health needs remain largely unmet, particularly among youth in geographically underserved communities. Digital peer support is a promising approach to expanding access to mental health support, yet real-world evidence on engagement patterns and clinical outcomes remains limited. Objective The purpose of this study was to characterize engagement patterns and real-world outcomes among adolescents and young adults enrolled in a commercially available, text-based peer support platform. Methods This retrospective observational study analyzed secondary data from 5673 adolescents and young adults enrolled in a commercially available digital peer support platform from January 29, 2023, through June 3, 2026. Engagement was operationalized as communication days per month. Standardized clinical outcome measures (Patient Health Questionnaire-9 [PHQ-9], Generalized Anxiety Disorder-7 [GAD-7], and World Health Organization-Five Well-Being Index [WHO-5]) were administered as part of routine measurement-based care. Ordinary least squares regression was used to examine predictors of engagement, and complete-case pre-post change scores were evaluated across 4 assessment windows among participants with paired assessments. Results The sample was predominantly female (4600/5673, 81.1%) with a mean age of 16.4 (SD 2.1) years and moderate-to-severe symptom burden at baseline (PHQ-9: mean 12.6, SD 6.1; GAD-7: mean 10.7, SD 5.0; WHO-5: mean 44.8, SD 21.0). Of enrolled adolescents and young adults, 98.1% (5565/5673) had at least one recorded engagement with the platform, with a mean of 4.56 (SD 6.12) communication days per month. Female sex was a significant positive predictor of engagement intensity (β=.64, SE 0.22; P =.004). Hispanic and Latino adolescents and young adults engaged significantly more frequently than White or non-Hispanic adolescents and young adults (β=.61, SE 0.26; P =.02). Health Professional Shortage Area (HPSA) shortage score was significantly and positively associated with engagement intensity (β=.08, SE 0.02; P <.001). Baseline symptom severity was not associated with engagement intensity (β=.094, SE 0.23; P =.68). Among participants with complete baseline and follow-up data (1437/5673, 25.3%), an exploratory complete-case analysis found within-measure paired scores improved significantly from baseline to follow-up across the PHQ-9, GAD-7, and WHO-5. At last assessment, 31.9% (237/742), 36.6% (222/606), and 37.8% (168/442) of adolescents and young adults met clinically meaningful improvement thresholds on the PHQ-9, GAD-7, and WHO-5, respectively. Conclusions Text-based peer support shows preliminary promise as a scalable approach to expanding mental health access for underserved adolescents, though clinical improvement estimates are based on the subpopulation exposed to the digital peer support platform and may not generalize to the full enrolled population. Prospective, controlled studies with more complete outcome ascertainment are needed to establish causal efficacy.
