Abstract

BACKGROUND: Depression and anxiety are the most common mental disorders in children and adolescents. Bibliotherapy is a treatment using written materials for mental health problems. Its main advantages are ease of use, low cost, low staffing demands, and greater privacy. Yet few meta-analyses have focused on the effect of bibliotherapy on depression and anxiety disorders in children and adolescents. METHODS: We included randomized controlled trials comparing bibliotherapy with control conditions for depression and anxiety in children and adolescents (aged ≤18 years). Five electronic databases (PubMed, Embase, Cochrane, Web of Science, and PsycINFO) were searched from inception to January 2017. Efficacy was defined as mean change scores in depression and anxiety symptoms. Acceptability was defined as the proportion of participants who discontinued the treatment. Random effects model was used. An intention-to-treat analysis was conducted. RESULTS: Eight studies with 979 participants were selected. At posttreatment, bibliotherapy was significantly more effective than the control conditions in reducing the symptoms of depression or anxiety (standardized mean difference, -0.52; 95% confidence interval [CI], -0.89 to -0.15). Bibliotherapy did not have statistically significantly more all-cause discontinuations than controls (risk ratios, 1.66; 95% CI, 0.93 to 2.95). We also performed subgroup analyses for efficacy outcomes in different categories (types of disorder, mean age, control conditions, and parental involvement) of studies and found that bibliotherapy has been more effective in depressive adolescents. LIMITATIONS: Limited studies were eligible in this review and hence there was potential publication bias. CONCLUSION: According to the findings in this review, bibliotherapy may be more beneficial in treating depression in adolescents, but shows less robust effects for anxiety in children. Further well-defined clinical studies should be performed to confirm these outcomes.

TL;DR

This meta-analysis of eight randomized trials (979 children/adolescents) found bibliotherapy significantly reduced depression or anxiety symptoms versus control at posttreatment, with a pooled SMD of −0.52 (95% CI −0.89 to −0.15). Effects were stronger for depressive adolescents than for anxious children, and the authors conclude bibliotherapy may be effective and acceptable for adolescent depression but less robust for childhood anxiety.

Key findings

  • Bibliotherapy was significantly more effective than control conditions at posttreatment for depression or anxiety symptoms: SMD −0.52 (95% CI −0.89 to −0.15; p=0.006), with high heterogeneity (I²=84%, p<0.00001).
  • All-cause discontinuation did not differ statistically between bibliotherapy and controls: RR 1.66 (95% CI 0.93 to 2.95; p=0.09), with moderate heterogeneity (I²=40%, p=0.14).
  • Subgroup analyses found bibliotherapy was significantly more beneficial for depressive patients (SMD −0.78, 95% CI −1.42 to −0.14; p=0.02) and adolescents (SMD −0.78, 95% CI −1.42 to −0.14; p=0.02), but less robust for anxiety patients (SMD −0.36, 95% CI −0.88 to 0.17; p=0.18) and children (SMD −0.36, 95% CI −0.88 to 0.17; p=0.18).
  • Sensitivity analysis excluding small studies (≤50 patients) changed the effect to SMD −0.13 (95% CI −0.36 to 0.11; p=0.30), and the Egger test indicated publication bias (t=−4.89, p=0.0014).

Methods

  • Systematic review and pairwise random-effects meta-analysis of randomized controlled trials comparing bibliotherapy alone with control conditions (wait-list, non-treatment, treatment as usual, or psychological placebo) for children and adolescents with depression and/or anxiety.
  • Five electronic databases (PubMed, Embase, Cochrane, Web of Science, PsycINFO) were searched from inception to January 2017; eight studies with 979 participants met inclusion criteria.
  • Efficacy was mean change in depression/anxiety symptoms; acceptability was all-cause discontinuation; analyses used intention-to-treat, subgroup analyses by disorder type, mean age, control condition, and parental involvement, plus sensitivity analysis excluding small samples.

Limitations

  • The paper states that limited studies were eligible and there was potential publication bias; it also notes significant heterogeneity from broad inclusion criteria, low overall study quality, lack of follow-up in six of eight studies, and no data on adverse effects or cost-effectiveness.
  • The paper states that included studies covered only adolescents with depressive symptoms or children with anxiety symptoms, so further research is needed on adolescents with anxiety and children with depression.
  • Evident from the text: the sensitivity analysis showed the efficacy result was not robust after excluding small studies, and the authors caution that small trials may exaggerate treatment effects; publication bias was also indicated by funnel plot asymmetry and the Egger test.

  • In the meta-analysis by Yuan et al., participants receiving bibliotherapy showed significant reductions in depression scores, with effects maintained during follow-up.

    “The analysis also found that participants receiving bibliotherapy appeared to showed significant reductions in depression scores, with effects maintained during follow-up.”

    From Recent developments in bibliotherapy for adolescent depression (2025) · cites this paper as [44]

    The Results (Subgroup analysis) report significantly lower depression symptoms with bibliotherapy than with controls in studies of depressive patients. But Results (Study selection and characteristics) says there were insufficient follow-up data to examine long-term effects, so the claim that the effects were maintained during follow-up is unsupported. (LLM, conf=0.92)

  • Bibliotherapy demonstrated high acceptability and low dropout rates in the meta-analysis by Yuan et al.

    “Additionally, the therapy demonstrated high acceptability and low dropout rates, making it particularly suitable for adolescents with mild to moderate depression (44).”

    From Recent developments in bibliotherapy for adolescent depression (2025) · cites this paper as [44]

    The Conclusion describes bibliotherapy as a potentially acceptable treatment for depression in adolescents. However, the Discussion says all-cause discontinuation in bibliotherapy groups remained high, contrary to the claim of low dropout. The cited passages also do not establish particular suitability for mild to moderate depression. (LLM, conf=0.88)

  • Bibliotherapy is particularly suitable for adolescents with mild to moderate depression.

    “Additionally, the therapy demonstrated high acceptability and low dropout rates, making it particularly suitable for adolescents with mild to moderate depression (44).”

    From Recent developments in bibliotherapy for adolescent depression (2025) · cites this paper as [44]

    The Conclusion says bibliotherapy may be an effective and acceptable treatment for depression in adolescents, and the Introduction reports a recommendation for mild-to-moderate depression. But the paper does not establish that it is particularly suitable for adolescents with that severity of depression. The citing sentence’s claim of low dropout rates also conflicts with the Discussion, which says discontinuation in bibliotherapy groups remained high. (LLM, conf=0.86)

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 by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-27.
