Abstract

Most substance use begins in adolescence. Both childhood trauma and associated post-traumatic stress disorder (PTSD) increase risk for early substance use, which is associated with greater eventual severity of substance use disorders (SUDs). When co-occurring, PTSD and SUD can reinforce and exacerbate each other, necessitating integrated treatment approaches. To systematically review existing literature on interventions for prevention or treatment of SUDs among adolescents (aged 10–24) with a history of trauma, with or without PTSD, we searched databases (PubMed, PsycInfo, CINAHL, Cochrane CENTRAL) using search terms related to substance use, trauma, adolescents, and interventions. Searches identified 8134 unique articles, 68 of which prompted full-text screening. Authors extracted data, applied the Effective Public Health Practice Project Quality Assessment Tool to evaluate the evidence, and synthesized findings. Thirty three articles met eligibility criteria, including 13 RCTs. Twenty studies (10 RCTs) evaluated interventions for substance use and co-occurring problems among youth with a history of trauma, predominantly via individual therapy based on cognitive-behavioral principles, although group therapy, case management, and other approaches have also been studied. Interventions with exposure-based components were infrequent but had robust results and minimal adverse outcomes. Thirteen studies examined differential response of youth with a history of trauma to standard SUD treatments, compared to youth without a history of trauma, with mixed findings. Youth with a history of trauma face elevated risk of SUDs and may respond differently to SUD treatments. Several promising interventions have been recently developed. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany 2023.

    Childhood trauma and associated PTSD raise the risk that a young person will begin using substances early.

      The Results (p. 8) report that adverse childhood experiences were associated with a higher likelihood of initiating illicit drug use in early adolescence. The paper does not establish that associated PTSD independently increases that risk; the cited evidence supports the childhood-trauma portion, not the PTSD portion. (LLM, conf=0.88)

      The Discussion (page unavailable) reports little evidence that improvement in one domain during adolescent substance-use treatment predicted better 12-month outcomes in the other. But the Introduction (page unavailable) notes some evidence that effective mental-health treatment may prevent subsequent substance-use disorders.

    Abused youth may feel different from peers and therefore gravitate to fringe social groups where substance use is more accepted.

      The Prevalence section says it is possible that children who have been abused feel “different” and withdraw toward fringe groups where alcohol use is more accepted. The citing sentence preserves that tentative explanation but broadens “alcohol use” to substance use generally, which the passage does not establish. (LLM, conf=0.84)

      The Results section reports that childhood adversities were common: 38.4%–39.1% of respondents reported at least one. The paper assessed a defined set of adversities occurring before age 18, not all potentially traumatic events among adolescents; it therefore does not support the claim that a majority of adolescents had experienced one.

      The Results report higher drug use and drug problems after maltreatment, and higher depressive symptoms after childhood-limited maltreatment; the Methods describe matching and adjustment for individual and family characteristics.

      The Discussion describes this as the first full-scale randomized trial of integrated exposure-based treatment for adolescents with co-occurring substance use problems and PTSD symptoms. The results report significant substance-use and some PTSD symptom outcomes at 18 months, but the assessments were 18 months after baseline, not 18 months after treatment. The paper does not establish that RRFT has the strongest evidence across the broader treatment literature, and overall PTSD symptom improvement did not differ significantly from treatment as usual.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
