How are families included in the treatment of adults affected by eating disorders? A scoping review.

OBJECTIVE
The involvement of families in the treatment of adults with eating disorders is recommended as a core component of comprehensive care, yet little is known about the optimal way to implement or routinely facilitate this. This article evaluates the recent evidence on the inclusion of families in treatment programs for adults with eating disorders.


METHOD
A systematic literature search was conducted to identify evidence of family inclusive treatment approaches for adults with eating disorders. A scoping review framework was applied to assess and synthesize findings.


RESULTS
Sixty-eight studies were identified. Substantial conceptual research contributing to the theoretical basis of current practice with families of adults with eating disorders and clinical applications in current use were identified. Most research used uncontrolled studies with few experimental designs, reflecting the standing of the extant literature. Common elements of existing approaches have been distinguished and shared core components of interventions identified.


DISCUSSION
Results confirmed that family members of adults were willing to be involved with eating disorder treatment services and appeared to respond to interventions of varying intensity and duration. The impact on individual patients, and effect on treatment outcomes, are yet to be established. The localized settings of existing studies, the homogenous nature of interventions used, and the limited diversity in research subjects, make it difficult to generalize from the results to the wide range of adult eating disorder presentations seen in practice. Suggestions for future research and further clinical developments are discussed.
