The prevalence of Avoidant/Restrictive Food Intake Disorder (ARFID) is unclear. This paper is the first to present meta-analysis based estimates of the prevalence of ARFID, and to assess the impact of the quality of the research on these estimates.

Design

A pre-registered (Prospero: CRD42023487621) systematic review and meta-analysis.

Methods

PubMed, PsychInfo, Web of Science and CINAHL were searched (final date of retrieval 30th July 2024) for peer reviewed papers published between 2013 and 2024. Random-effects and quality effects meta-analyses were used to compute and compare prevalence estimates and to evaluate the impact of study quality on prevalence rates. Subgroups were also considered (gender, age group, clinical status). Loney et al.'s (1998) Critical Appraisal of the Health Research Literature: Prevalence or Incidence of a Health Problem scale was used to assign each study a quality score across three categories - methodological validity (six points); interpretation of results (one point); and applicability of the results (one point).

Results

Twenty-six studies were identified (n = 122,861). Meta-analysis using random-effects indicated a prevalence of 11.14 % (95 % CI 8.16–14.5 %), whereas quality effects prevalence was 4.51 % (95 % CI 0.7–10.68 %). Similar contrasts were evident among subgroups.

Conclusions

Even taking the more conservative estimate of 4.51 %, this review demonstrates that ARFID is a common disorder, meriting further research and clinical and service developments. Future research needs to be more methodologically robust (larger samples; standardised diagnostic measures; clearer data presentation).

Digital addiction (DA) has been identified as an emerging public health problem worldwide. However, the extent and direction of the association between DA and interpersonal relationships (IRs) are unknown. Does DA have adverse effects on IRs, and how credible is the evidence for this association in published analyses of real-world data? Using the PRISMA method, we conducted a meta-analysis to quantitatively synthesize the results of the relevant studies and obtain reliable effect size estimates and performed an analysis of moderating factors. A systematic literature search identified 98 studies involving 134,593 participants and 99 effect sizes. A significant negative association was observed between DA and IRs. Importantly, our meta-analysis revealed that the DA subtype has no significant moderating effect on IRs, suggesting that combining numerous categories of DA rather than focusing on specific forms of DA may be appropriate for understanding the relationship between DA and IRs. Relative to the IR subtype, the association between DA and offline relationships is significant and negative, whereas the association between DA and online relationships is significant and positive. The strength of the relationship is also influenced by the participants' sex ratio, educational level, and measurement tools. These results may help resolve the disagreement over the magnitude and direction of the association between DA and IRs and have potential implications for the treatment of DA.

We tested the association between gender nonconformity and common mental health outcomes, including generalized anxiety symptoms, depressive symptoms, self-esteem, self-harm attempts, and suicide attempts using an exhaustive meta-analysis. PsycInfo, ProQuest Central, EBSCOhost, and PubMed were searched for eligible articles using either cross-sectional or longitudinal designs on 11th July 2024. A total number of 1975 articles were identified and selected following PRISMA. Twenty-five, 48, 32, seven, and nine studies were included on generalized anxiety symptoms, depressive symptoms, self-esteem, self-harm attempts, and suicide attempts, reaching a total sample size of 142,069, 188,681, 27,488, 47,523, and 25,573, respectively. Meta-analyses were performed using a random-effects model stratified by mental health outcomes. We found that higher levels of gender nonconformity were associated with higher levels of generalized anxiety (r = 0.06) and depressive symptoms (r = 0.11), lower levels of self-esteem (r = 0.18), and increased risk of self-harm (r = 0.17) and suicide attempts (r = 0.14). Gender nonconformity had stronger links to generalized anxiety symptoms, depressive symptoms, and self-esteem in men than in women. Behaviors-based gender nonconformity showed stronger links to depressive symptoms and self-esteem compared to traits-based gender nonconformity. The effect size for the association between gender nonconformity and depressive symptoms was significantly larger in adolescent samples than in childhood samples. There was no significant moderation by sexual orientation. While gender nonconformity is robustly associated with a range of common mental health problems, the magnitude of this association varies depending on the specific mental health outcomes considered and sex. Interventions to mitigate mental health differences and improve overall well-being among individuals who display greater gender nonconformity are needed.

Introduction

There is considerable research focusing on the negative outcomes of psychotherapy, however, there remains an overlooked population: those who appear to show no response after treatment. This qualitative evidence synthesis aimed to review the available literature exploring client and therapist experiences of psychotherapy nonresponse.

Method

Seven databases were searched for studies using qualitative approaches to explore nonresponse. Twenty-four studies met inclusion criteria and were analysed using Thematic Synthesis.

Results

Six overarching client perspective themes and 18 subthemes were identified: Hopes and fears; A difficult task; A Disconnected relationship; Staying involved; Therapy was not worth the investment and, On a trajectory for improvement. Four overarching therapist perspective themes and 10 subthemes were identified: High expectations; Experiencing a disconnect; Feeling threatened and Holding onto hope.

Discussion

A model of psychotherapy nonresponse is proposed. The experience of nonresponse appears to involve both clients and therapists finding therapy difficult, experiencing problems connecting and not being open in the therapeutic relationship. Importantly, nonresponse appears not to be an absence of effects, but a range of experiences that are potentially harmful, particularly to clients. However, there were varied experiences of nonresponse, which indicates the importance of qualitative outcome measurement.

Growing research suggests that death anxiety may be transdiagnostic, playing a key role in the development and symptomology of psychopathology. This meta-analysis examined the relationship between death anxiety and mental illness symptoms. In total, 104 papers were included, representing cross-sectional data from 99 studies (n_total = 24,434), and experimental data from 11 studies (n_total = 1372). Meta-analyses of cross-sectional studies indicated a moderate correlation (r = 0.397) between death anxiety and overall mental illness symptoms. The clinical nature of the group emerged as a significant moderator of this effect. In addition, the relationship between death anxiety and mental illness symptoms was larger for clinical samples (r = 0.580), and for anxiety-related symptoms (r = 0.506) than for depression. Additional meta-analyses of 11 mortality salience studies revealed that death reminders had an overall moderate impact on clinical symptoms (Hedge's g = 0.481). The relevance of the sample to the symptom being measured significantly predicted this relationship; that is, the effect was moderate-to-large (Hedge's g = 0.671) when excluding comparison subgroups for which the effect was not predicted by the authors. The clinical nature of the sample did not significantly moderate the effect. The experimental studies were generally of higher quality and lower risk of publication bias compared to cross-sectional studies. These findings support the strong transdiagnostic role of death anxiety across numerous disorders. Clinical implications include the potential need to treat death anxiety directly, to maximise long-term therapy benefits.

This study undertakes a scoping review of reviews on barriers to accessing mental health care for refugees and asylum seekers in high-income countries. By assessing mental health care access using the Levesque's conceptual framework, we identify barriers along the patient care pathway and highlight research gaps. Following PRISMA-ScR guidelines, 10 relevant systematic and scoping reviews were identified and analyzed. Seven common barriers were identified, that could be located across different stages of the conceptual framework. Demand-side barriers included: (1) refugees' understanding of mental illness, (2) fear of stigma, (3) lack of awareness of services, (4) attitudes towards formal treatment; while supply-side barriers comprised: (5) language barriers, (6) practical and structural issues, and (7) providers' attitudes and competence. There was a focus on demand-side barriers as key determinants for low service use. We observed a paucity of quantitative studies linking barriers and indicators of access to care. In the context of well-established mental health care systems, previous research has largely explained low access through peculiarities of refugees and asylum seekers, thereby neglecting the role of supply-side factors (including system structures and attitudes of service providers). We discuss how future research can critically question prevailing assumptions and contribute to rigorous evidence.

Introduction

Several systematic reviews and meta-analyses have been conducted on the risk and protective factors of youth crime. This study aims to consolidate this evidence using an umbrella review methodology.

Methods

A systematic electronic search was conducted using multiple electronic databases. Strength of associations was evaluated using quantitative umbrella review criteria, and AMSTAR was used to assess the quality of the studies.

Results

Among the 58 factors identified, 11 factors were supported by highly suggestive or suggestive evidence. Evidence of association was highly suggestive (class II) for substance use (odds ratio [OR] = 2·29, 95%CI 1·58–3.01), previous history of crime (OR = 2·03, 95%CI 1·62–2·45), moral development (OR = 3·98, 95%CI 3·57–4·39), psychopathology (OR = 2·22, 95%CI 1.40–2.69), adverse childhood experiences (OR = 1·37, 95%CI = 1·36–1·38), poor parental supervision (OR = 1·85, 95%CI 1·83–1·87), maltreatment or neglect (OR = 1·34, 95%CI 1·08–1·65), attachment (OR = 1·94; 95%CI 1.93–1·95), and school bullying (OR = 2·50; 95%CI 2·03–3·08); and suggestive (class III) for peer pressure (OR = 2·11, 95%CI 2·06–2·16) and supportive school environments (OR = 0·56; 95%CI 0·55–0·57).

Conclusion

The evidence-based atlas of key risk and protective factors identified in this umbrella review could be used as a benchmark for advancing research, prevention, and early intervention strategies for youth crime.
