Common caregiver illness representations in the context of family-based treatment: Commentary on Marchetti and Sawrikar (2023).

Abstract

In their systematic review on parent illness representations in their children with anorexia nervosa (AN), Marchetti and Sawrikar (International Journal of Eating Disorders, 2023) integrate past research on the parental experience of the illness, investigating whether the Common Sense Model of Self-Regulation (CSM) is a useful framework for understanding parental responses to AN. Given that family-based treatment (FBT) is a first-line treatment for adolescents with eating disorders and is based upon integrating parents into the treatment process, it is especially relevant to explore how parent illness representations may impact FBT. In this commentary, we describe how FBT is designed to support parents and address many of the common unhelpful beliefs and emotions associated with parenting an adolescent with AN. We include specific examples of how parents can be supported within FBT as manualized. We also examine parental representations that may not be addressed by FBT, and how these may impact treatment outcomes in FBT, possibly via the impact of expressed emotion. Future research is needed to determine if modifications to FBT are required to address parental representations of the illness. We end by expanding upon Marchetti and Sawrikar's suggestions on how treatment could be extended to better support parents as necessary.
