BACKGROUND

Internalizing disorders (IDs), primarily depression and anxiety, are highly prevalent among adolescents receiving community-based treatment for substance use disorders (SUDs). For such clients, interventions that do not holistically address both SUDs and IDs are less effective.

OBJECTIVE

This pilot treatment development study aims to develop and test a modular treatment protocol for addressing cooccurring IDs among adolescents (aged 13 to 18 years) enrolled in routine care for substance use problems: Family Support Protocol for Adolescent Internalizing Disorders (Fam-AID). As an adjunctive protocol, Fam-AID will not require clinicians to markedly alter existing base practices for SUD. It will be anchored by 3 evidence-based foundations for treating cooccurring adolescent IDs: family engagement techniques, transdiagnostic individual cognitive behavioral therapy techniques, and family psychoeducation and safety planning.

METHODS

This quasi-experimental study will proceed in 2 stages. The pilot stage will use rapid-cycle prototyping methods in collaboration with end-user stakeholders to draft protocol delivery and fidelity guidelines adapted from existing resources, solicit provider and client input on protocol content and delivery via cognitive interviewing, and pilot prototype components on 4 to 6 cases. The second stage will be an interrupted time series study for 60 comorbid SUD+ID cases across 2 sites serving diverse adolescents: 30 will receive treatment as usual (TAU); following clinician training in the protocol, 30 new cases will receive TAU enhanced by Fam-AID. For aim 1, the focus is on evaluating the acceptability of the Fam-AID protocol through therapist and client interviews as well as assessing fidelity benchmarks using therapist- and observer-reported protocol fidelity data. For aim 2, the plan is to compare the effects of TAU only cases versus TAU+Fam-AID cases on family treatment attendance and on adolescent ID and substance use symptoms, with measurements taken at baseline and at 3-month and 6-month follow-ups.

RESULTS

Study recruitment will begin in April 2025.

CONCLUSIONS

We anticipate that Fam-AID will contain 5 treatment modules that can be delivered in any sequence to meet client needs: <i>family engagement</i> of primary supports in treatment planning and services; <i>relational reframing</i> of family constraints, resiliencies, and social capital connected to the adolescent’s ID symptoms; <i>functional analysis</i> of the adolescent’s ID symptoms and related behaviors; <i>cognitive behavioral therapy</i> to address the adolescent’s ID symptoms and functional needs, featuring 3 core techniques (emotion acceptance, emotional exposure, and behavioral activation) to address negative affect and emotional dysregulation; and <i>family psychoeducation and safety planning</i> focused on education about comorbid SUD+ID and prevention of adolescent self-harm. If the abovementioned modules are found to be feasible and effective, Fam-AID will offer a set of pragmatic interventions to SUD clinicians for treating cooccurring IDs in adolescent clients.
