Virtually delivered guided self-help for binge eating disorder and bulimia nervosa: findings from a service evaluation.

BACKGROUND: Timely intervention is beneficial to the effectiveness of eating disorder (ED) treatment, but limited capacity within ED services means that these disorders are often not treated with sufficient speed. This service evaluation extends previous research into guided self-help (GSH) for adults with bulimic spectrum EDs by assessing the feasibility, acceptability, and preliminary effectiveness of virtually delivered GSH using videoconferencing. METHOD: Patients with bulimia nervosa (BN), binge eating disorder (BED) and other specified feeding and eating disorders (OSFED) waiting for treatment in a large specialist adult ED out-patient service were offered virtually delivered GSH. The programme used an evidence-based cognitive behavioural self-help book. Individuals were supported by non-expert coaches, who delivered the eight-session programme via videoconferencing. RESULTS: One hundred and thirty patients were allocated to a GSH coach between 1 September 2020 and 30 September 2022; 106 (82%) started treatment and 78 (60%) completed treatment. Amongst completers, there were large reductions in ED behaviours and attitudinal symptoms, measured by the ED-15. The largest effect sizes for change between pre- and post-treatment were seen for binge eating episode frequency (d = -0.89) and concerns around eating (d = -1.72). Patients from minoritised ethnic groups were over-represented in the non-completer group. CONCLUSIONS: Virtually delivered GSH is feasible, acceptable and effective in reducing ED symptoms amongst those with bulimic spectrum disorders. Implementing virtually delivered GSH reduced waiting times, offering a potential solution for long waiting times for ED treatment. Further research is needed to compare GSH to other brief therapies and investigate barriers for patients from culturally diverse groups.

National roll-out of early intervention for eating disorders: Process and clinical outcomes from first episode rapid early intervention for eating disorders.

AIM: First Episode Rapid Early Intervention for Eating Disorders (FREED) is an early intervention model for young people with recent-onset eating disorders (ED). Promising results from a previous single-centre study and a four-centre study (FREED-Up) have led to the rapid national scaling of FREED to ED services in England (FREED-4-All). Our aim was to evaluate duration of an untreated ED (DUED), wait time target adherence, and clinical outcomes in FREED-4-All and compare these to the (benchmark) findings of the earlier FREED-Up study. METHOD: FREED services submit de-identified data to the central FREED team quarterly. The current study covers the period between September 2018 and September 2021. This FREED-4-All dataset includes 2473 patients. These were compared to 278 patients from the FREED-Up study. RESULTS: DUED was substantially shorter in the FREED-4-All dataset relative to the FREED-Up study (15 vs. 18 months). Adherence to the wait time targets was comparable in both cohorts (~85% of engagement calls attempted in <2 days, ~50%-60% of assessments offered in <14 days, ~40% of treatment offered in <28 days). Patients in the FREED-4-All dataset experienced significant improvements in ED and general psychological symptoms from pre- to post-treatment that were comparable to the FREED-Up study. These findings should be interpreted cautiously as only 6% of FREED-4-All patients had post-treatment data. CONCLUSIONS: Data from the FREED-4-All evaluation suggest that FREED is replicating at scale. However, these data are flawed, uncertain, proximate, and sparse and should therefore be used carefully alongside other evidence and clinical experience to inform decision making.
