Objective: Depression and anxiety are the most prevalent mental health problems in youth, yet almost nothing is known about what outcomes are to be expected at the individual level following routine treatment. This paper sets out to address this gap by undertaking a systematic review of outcomes following treatment as usual (TAU) with a particular focus on individual-level outcomes. Method: MEDLINE, Embase and PsycInfo were searched for articles published between 1980 and January 2019 that assessed TAU outcomes for youth depression and anxiety accessing specialist mental health care. Meta-analysis considered change at both group-level preÀpost effect size (ES) and individual-level recovery, reliable change, and reliable recovery. Temporal analysis considered stability of primary and secondary outcomes over time. Subgroup analysis considered the moderating effect of informant; presenting problem; study design; study year; mean age of youth; use of medication; intervention dosage and type of treatment offered on outcomes. A protocol was preregistered on PROSPERO (CRD42017063914). Results: Initial screening of 6,350 publications resulted in 38 that met the inclusion criteria, and that were subsequently included in meta-analyses. This resulted in a final full pooled sample of 11,739 young people (61% of whom were female, mean age 13.8 years). The preÀpost ES (Hedges' g) at first/final outcome (13/26 weeks) was À0.74/À0.87. The individual-level change on measures of self-report was 38% reliable improvement, 44% no reliable change, and 6% reliable deterioration. Outcomes varied according to moderators, informant, problem type and dosage. Conclusion: Poor data quantity and quality are limitations, but this is the first study that indicates likely rates of reliable improvement for those accessing TAU. We propose the need for improved reporting of both individual-level metrics and details of TAU to enable greater understanding of likely current outcomes from routine care for youths with depression and anxiety in order to allow the potential for further improvement of impact.

Background. Many young people with anxiety or depression drop out of treatment early, and/or leave treatment without showing measurably improved symptom levels. To enhance treatment engagement and effectiveness, it is critical to better understand how young people's perceptions of the symptoms, causes, consequences, treatability, and course of their anxiety and depression influence engagement.Aim. This study aimed to provide a qualitative account of illness perceptions among youth with anxiety and depression by applying the Common Sense Model of Self-Regulation (CSM), which was developed in physical health contexts.Methods. Semi-structured interviews were conducted with 26 young people (aged 16-24, 73% female) with a history of anxiety and/or depression. Interviews were analysed using a combination of theory-and data-driven analysis techniques, consisting primarily of deductive thematic analysis.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
