ObjectiveThis qualitative review sought to explore how young people (YP) conceptualize positive outcomes from cognitive‐behavioral therapy (CBT) and what YP perceive to be the facilitators and barriers to positive outcomes.MethodsA systematic literature search was conducted in June 2021 using six online databases. Studies were included if qualitative data were collected from participants who were aged up to 25, had internalizing mental health difficulties, and had received in‐person CBT from trained practitioners.ResultsNineteen studies were included. The Gough Weight of Evidence framework was used to assess methodological and topical quality and relevance. A thematic synthesis identified 34 conceptualizations of positive outcomes, 57 facilitators, and 49 barriers. Descriptive and analytical themes were identified. In line with the review's pragmatic perspective, the latter were worded as practice recommendations: acknowledge YP's perspectives on outcomes, teach tangible CBT techniques, balance autonomy and support, frame CBT as “upskilling,” explore nuanced barriers to engagement, and consider the power of group dynamics.ConclusionsThis review established the range of YP's views about positive outcomes from CBT, as well as facilitators and barriers to achieving these. Findings should prompt CBT practitioners to reflect and consider how their practice might be shaped through reports from YP as experts by experience.
