Parent-based Treatment for Youth With Anxiety and Obsessive-compulsive Disorder

Anxiety and obsessive-compulsive disorders are the most common mental health disorders in childhood and adolescence. Parental accommodation of their children's avoidance, escape, safety behaviors are a set of parenting behaviors that have been most strongly associated with child anxiety and obsessive-compulsive disorder. Developing and testing parent-led interventions that target accommodation and parenting styles associated with anxiety has the potential to improve treatment outcomes and reach families who may not otherwise access care (for example, for youth who refuse to attend therapy). A parenting intervention for youth with anxiety has been recently developed to address these goals called Supportive Parenting of Anxious Childhood Emotions ("SPACE"). In this intervention, therapists meet individually with parents to help them reduce accommodation and support adaptive behaviors in their children. SPACE was recently shown to be non-inferior to individual cognitive-behavioral therapy with 88% of youth being classified as responders to SPACE. The purpose for the proposed study is to demonstrate the treatment efficacy of SPACE compared to a low-contact, therapist-supported bibliotherapy version of this intervention, providing efficacy evidence for SPACE as delivered by an independent investigatory group.
