A systematic scoping review of carer accommodation in eating disorders

The accommodation of eating disorder (ED) behaviours by carers is one of the maintaining processes described in the cognitive interpersonal model of anorexia nervosa. This systematic scoping review aimed to explore studies examining accommodating and enabling behaviour, including how it impacts upon the carer's own mental health and the outcome of illness in their loved ones.

In this systematic scoping review, five databases (PubMed, Web of Science, MEDLINE, PsycInfo, CINAHL) were searched for studies measuring accommodating and enabling behaviour in carers of people with EDs. A total of 36 studies were included, of which 10 were randomised trials, 13 were longitudinal studies, nine were cross-sectional studies and four were qualitative studies. Carers of people with EDs were found to have high level of accommodating and enabling behaviour which reduced following treatment, although no single type of intervention was found to be superior to others. Higher accommodation in carers was associated with higher level of emotional distress, anxiety and fear. There was mixed evidence around whether accommodating and enabling behaviour in carers impacted the outcome of illness in their loved ones.

Accommodating and enabling behaviours are frequently seen in carers of people with AN, and carer-focused interventions are able to reduce these behaviours, although it is unclear if any intervention shows superiority. There may be nuances in the impact of these behaviours related to interactions within the support network and variations in the forms of co-morbidity in patients. More studies with a larger sample size and which include both mothers and fathers are required.
