Cognitive behavior therapy for adult eating disorders in routine clinical care: A systematic review and meta-analysis.

OBJECTIVE: Cognitive behavior therapy (CBT) is a recommended treatment for eating disorders (ED) in adults given its evidence, mainly based on efficacy studies. However, little is known about how CBT works in routine clinical care. The goal of the present meta-analysis is to investigate how CBT works for various ED when carried out in routine clinical settings. METHOD: Ovid MEDLINE, Embase OVID, and PsycINFO were systematically searched for articles published until June 2023. The outcome of CBT, methodological quality, risk of bias (RoB), and moderators of treatment outcome were examined and benchmarked by meta-analytically comparing with efficacy studies for ED. Fifty studies comprising 4299 participants who received CBT were included. RESULTS: Large within-group effect sizes (ES) were obtained for ED-psychopathology at post-treatment (1.12), and follow-up (1.22), on average 9.9 months post-treatment. Attrition rate was 25.5% and RoB was considerable in the majority of studies. The benchmarking analysis showed that effectiveness studies had very similar ESs as efficacy studies (1.20 at post-treatment and 1.28 at follow-up). CONCLUSION: CBT for ED is an effective treatment when delivered in routine clinical care, with ESs comparable to those found in efficacy studies. However, the evidence needs to be interpreted with caution due to the RoB in a high proportion of studies. PUBLIC SIGNIFICANCE: Eating disorders are common in the population and often lead to multiple negative consequences. CBT has been found effective for ED and is recommended in clinical guidelines. Since these recommendations are primarily based on university studies we wanted to investigate how CBT performs in routine clinical care. Our meta-analysis found that CBT worked as well in routine care as in university setting studies.

OBJETIVO: La terapia cognitivo-conductual (TCC) es un tratamiento recomendado para los trastornos de la conducta alimentaria (TCA) en adultos debido a su evidencia, basada principalmente en estudios de eficacia. Sin embargo, se sabe poco sobre cómo funciona la TCC en la atención clínica rutinaria. El objetivo de este meta-análisis es investigar cómo funciona la TCC para diversos TCA cuando se lleva a cabo en entornos clínicos habituales. MÉTODO: Se realizó una búsqueda sistemática en Ovid MEDLINE, Embase OVID y PsycINFO de artículos publicados hasta junio de 2023. Se examinaron el resultado de la TCC, la calidad metodológica, el riesgo de sesgo y los moderadores del resultado del tratamiento, y se compararon metaanalíticamente con estudios de eficacia para TCA. Se incluyeron cincuenta estudios que comprendían a 4299 participantes que recibieron TCC. RESULTADOS: Se obtuvieron tamaños del efecto (TE) grandes dentro del grupo para la patología de los TCA en el post-tratamiento (1.12) y en el seguimiento (1.22), en promedio 9.9 meses después del post-tratamiento. La tasa de abandono fue del 25.5% y el riesgo de sesgo fue considerable en la mayoría de los estudios. El análisis de comparación mostró que los estudios de efectividad tenían TE muy similares a los estudios de eficacia (1.20 en el post-tratamiento y 1.28 en el seguimiento). CONCLUSIÓN: La TCC para los TCA es un tratamiento efectivo cuando se administra en la atención clínica rutinaria, con TE comparables a los encontrados en estudios de eficacia. Sin embargo, la evidencia debe interpretarse con cautela debido al riesgo de sesgo en una alta proporción de los estudios.

The Cultural Formulation Interview as a clinical tool in the assessment of eating disorders: a pilot study.

Background: The Cultural Formulation Interview (CFI) in the DSM-5 is a person-centered instrument for systematically appraising the impact of sociocultural factors in psychiatric assessment. The CFI has been shown to be feasible, acceptable, and useful in various clinical contexts. However, to this date there is only one published report describing the use of the CFI with patients with eating disorders. Aims: To explore the potential benefits and challenges of utilizing the CFI in the assessment of eating disorders. Methods: As an addendum to an ongoing qualitative study about barriers to treatment for eating disorders for individuals with a migration background in Sweden, we utilized the CFI in the assessment of adult patients (n=8) in specialist eating disorder treatment. Interview data were analyzed employing a thematic analysis framework. Participants provided feedback using a standard form for evaluation of the CFI. Results: Certain CFI questions proved especially meaningful in this context. In response to the CFI question about patient explanatory models, previously unrecognized ideas about causation emerged. These included perfectionism-a known risk factor for eating disorders-based on immigrant parents' career expectations and experiences of strict family control over life choices. In response to the CFI questions on cultural identity and its impact, the participants provided rich descriptions including important themes such as religion, racism, and ambiguities associated with being a second-generation immigrant. The final CFI question, eliciting concern about the patient-clinician relationship, revealed numerous examples of prejudice and unfamiliarity with migrant groups among healthcare providers. Implications: The CFI can be useful in the assessment of patients with eating disorders and should be further explored as a standard tool in specialist eating disorder services.

Migration background, eating disorder symptoms and healthcare service utilisation: findings from the Stockholm Public Health Cohort.

BACKGROUND: From a global perspective, eating disorders are increasingly common, probably because of societal transformation and improved detection. However, research on the impact of migration on the development of eating disorders is scarce, and previously reported results are conflicting. AIMS: To explore if eating disorder symptom prevalence varies according to birth region, parents' birth region and neighbourhood characteristics, and analyse if the observed patterns match the likelihood of being in specialist treatment. METHOD: This study uses data from a large population-based health survey (N = 47 662) among adults in Stockholm, Sweden. A general linear model for complex samples, including adjustment for gender and age, was used to explore self-reported eating disorder symptoms. Odds ratios were calculated for individual symptoms. RESULTS: Eating disorder symptoms are substantially more common in individuals born abroad, especially for migrants from a non-European country. This holds true for all surveyed symptoms, including restrictive eating (odds ratio 5.5, 95% CI 4.5-6.7), compensatory vomiting (odds ratio 6.1, 95% CI 4.6-8.0), loss-of-control eating (odds ratio 2.6, 95% CI 2.3-3.1) and preoccupation with food (odds ratio 2.3, 95% CI 1.9-2.8). Likewise, symptoms are more common in individuals with both parents born abroad and individuals living in districts with a high percentage of migrant residents. A gap exists between district-level symptom scores and the likelihood of being in specialist eating disorder treatment. CONCLUSIONS: These findings call for oversight of current outreach strategies, and highlight the need for efforts to reduce stigma and increase eating disorder symptom recognition in broader groups.
