N2 - Background: Feeding and eating disorders are associated with significant illness burden and costs, yet access to evidence-based care is limited. Low intensity psychological interventions have the potential to increase such access. Methods: A systematic review and meta-analysis were conducted on the use of low intensity psychological interventions for the treatment of feeding and eating disorders. Studies comparing low intensity psychological interventions against high intensity therapies and non-eating disorder specific psychological interventions were included, as well as those with waiting list control arms. There were three primary outcomes: eating disorder psychopathology, diagnostic and statistical manual of mental disorders (DSM) severity specifier-related outcomes and rates of remission/recovery. Results: Thirty-three studies met the inclusion criteria, comprising 3665 participants, and 30 studies were included in the meta-analysis. Compared to high intensity therapies, low intensity psychological interventions were equivalent on reducing eating disorder psychopathology (g = − 0.13), more effective at improving DSM severity specifier-related outcomes (g = − 0.15), but less likely to achieve remission/recovery (risk ratio (RR) = 0.70). Low intensity psychological interventions were superior to non-eating disorder specific psychological interventions and waiting list controls across all three primary outcomes. Conclusion: Overall, findings suggest that low intensity psychological interventions can successfully treat eating disorder symptoms. Few potential moderators had a statistically significant effect on outcome. The number of studies for many comparisons was low and the methodological quality of the studies was poor, therefore results should be interpreted with caution. More research is needed to establish the effectiveness of low intensity psychological interventions for children and young people, as well as for individuals with anorexia nervosa, avoidant/restrictive food intake disorder, pica and rumination disorder.
