Background and Aim. Family accommodation has been identified as a maintaining factor of eating disorders, with families often caught up in the rigid behaviours that characterise the illness. Given that parents often accommodate symptoms of their child’s eating disorder to reduce family conflict and the young person’s distress, levels of parents’ distress tolerance may help explain the variability seen in family accommodation. This study aimed to investigate the relationship between parental distress tolerance (specifically tolerance of negative emotions and intolerance of uncertainty) and family accommodation and assess the role of illness severity, caregiver burden, and parents’ mental health on this association.
