Effectiveness of Interventions for Interpersonal Functioning Among Adolescents With Posttraumatic Stress Symptoms: A Meta-Analysis.
Synthesis in Journal of adolescence, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAdolescents with posttraumatic stress symptoms often experience interpersonal difficulties; however, the effectiveness of existing interventions in improving interpersonal functioning remains unclear. This meta-analysis aimed to evaluate the effectiveness of current interventions on interpersonal functioning among adolescents with posttraumatic stress symptoms.
methodsA systematic search identified 17 studies comprising 35 therapeutic effect sizes that met the inclusion criteria. Effect sizes were synthesised using meta-analytic procedures, and potential moderators, including intervention type, mode, and number of sessions, were examined.
resultsThe aggregated post-intervention effect size was small but statistically significant (g = 0.39, p < 0.001, 95% CI [0.28, 0.49]). Intervention type and mode significantly moderated outcomes. Trauma-Focused Cognitive Behavioural Therapy (TF-CBT) demonstrated the largest effect size, while mixed intervention formats involving both individual and conjoint or group sessions showed greater efficacy than group-only approaches. At the 3-month follow-up, based on six effect measurements, the aggregated effect size was medium (g = 0.54, p < 0.001, 95% CI [0.28, 0.81]). Although the number of sessions did not significantly moderate post-intervention outcomes, interventions with more sessions were associated with stronger follow-up effects.
conclusionsCurrent interventions demonstrate small post-intervention and medium follow-up effects on interpersonal functioning. However, the findings highlight a lack of robust and consistent evidence regarding the adequacy and long-term effectiveness of existing interventions. Further high-quality research is needed to examine interventions that directly target trauma-related mechanisms influencing interpersonal functioning and to rigorously evaluate their long-term effectiveness among adolescents with posttraumatic stress symptoms.
