A systematic scoping review of carer accommodation in eating disorders.

Background: 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. Methods and results: 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. Conclusion: 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. Plain English Summary: Eating disorders are complex mental health conditions which also significantly affect the physical health of patients and the carers who support these patients. In this systematic scoping review, the authors have examined the impact of eating disorders on carer's emotional reactions and behaviour towards the eating disorder symptoms, namely accommodating and enabling behaviour towards the illness. For this review the authors searched for published studies that examined accommodating behaviour in carers of people with any type of eating disorder, which includes studies such as randomized trials, longitudinal studies, cross-sectional studies and qualitative studies. Higher levels of accommodation in carers was associated with higher levels of their emotional distress, anxiety and fear. Accommodating and enabling behaviours reduced with treatment although no single type of intervention was more effective in this regard than others. There was mixed evidence for the impact of accommodating and enabling behaviour in carers on the outcome of eating disorders in the patients. [ABSTRACT FROM AUTHOR]
