Digital Mental Health Interventions for Pediatric Anxiety Disorders: A Meta-Analysis of Therapist-Guided vs. Self-Guided Formats

Abstract

Introduction: Access to cognitive behavioral therapy (CBT) for pediatric anxiety disorders is limited. Digital mental health interventions (DMHIs) offer scalable alternatives, but the necessity of therapist guidance is unclear. This meta-analysis compares guided versus self-guided DMHIs for anxiety in children and adolescents.

Methods: We searched PubMed, PsycINFO, and Scopus for RCTs evaluating DMHIs (internet or app-based CBT) for anxiety disorders (separation, social, generalized anxiety) in youth ≤18 years. Primary outcome: anxiety symptom severity (standardized mean difference, SMD). Secondary: remission rates. Subgroup analysis by guidance level (therapist-guided vs. self-guided with automated reminders vs. pure self-guided). Random-effects meta-analysis.

Results: Twenty-seven RCTs (n=4,891 youth) were included. DMHIs significantly reduced anxiety versus waitlist control (SMD –0.72, 95% CI –0.89 to –0.55). Therapist-guided interventions had largest effect (SMD –0.91, –1.12 to –0.70), followed by automated-guided (SMD –0.58, –0.79 to –0.37), then pure self-guided (SMD –0.31, –0.51 to –0.11). Differences between guidance levels were significant (p<0.001). Remission rates: 48% for therapist-guided, 35% automated-guided, 22% self-guided, 12% waitlist. Dropout was lowest in therapist-guided (18% vs. 31% self-guided).

Discussion: Therapist guidance substantially improves DMHI efficacy for pediatric anxiety, likely through accountability, personalized feedback, and exposure support. Self-guided programs, while better than nothing, produce modest effects. Cost-effectiveness trade-offs favor guided DMHIs for moderate-severe anxiety.

Conclusions: Digital CBT for pediatric anxiety is effective, but therapist guidance yields superior outcomes. Clinicians should recommend guided DMHIs when available. Self-guided DMHIs are appropriate for mild anxiety or as a bridge to care.
