Exposure-based cognitive-behavioral therapy (CBT) is a well-established treatment for anxiety disorders and obsessive-compulsive disorder (OCD) in youth. Although a majority of youth respond to CBT, a substantial portion remain symptomatic and/or experience a return of symptoms after completing a course of treatment. This highlights the need for further improvements to this evidence-based treatment. Given that parent behaviors can negatively influence treatment, addressing parental behaviors in CBT serves as a novel and promising treatment target to improve youth's therapeutic outcomes. The authors review three common parent behaviors that influence anxiety and treatment outcomes: family accommodation, parent anxious behaviors, and management of disruptive behaviors. The authors then discuss each behavior, its effect on anxiety/OCD and treatment, and how to address the behavior within the context of CBT. In doing so, therapeutic learning can be optimized to improve CBT outcomes for youth with anxiety disorders and/or OCD.
