Accommodation refers to the ways in which family members act to alleviate a child's symptoms and distress. In the context of youth obsessive-compulsive disorder (OCD) and anxiety, accommodation may contribute to the development and maintenance of the disorder. We review the theory and research literature on accommodation, including measures of accommodation. Findings support the idea that accommodation is not a preferred parenting strategy; the sequelae of accommodation are negative and are often associated with both parent and sibling distress. Accommodation should be assessed and targeted in treatment for youth OCD and anxiety. We conclude by identifying several areas for future research, including the development of interventions that specifically target accommodation, the evaluation of potential family factors implicated in accommodation, and the exploration of the construct of accommodation in other childhood disorders.
