Abstract:

Over the past two decades, the understanding of Oppositional Defiant Disorder (ODD) has advanced substantially, revealing it to be more severe and impairing than previously recognized. While Parent Management Training (PMT) remains the gold standard treatment, its limitations, including persistent symptoms in about 50% of youth and high attrition, highlight the need for more effective and acceptable alternatives. Concurrently, shifts in parenting philosophies have led to an increased interest in relationship-based approaches. This thesis examines the efficacy and acceptability of Collaborative and Proactive Solutions (CPS) as an alternative to PMT in treating youth with ODD. The first study replicated and extended Ollendick et al.’s (2016) randomized controlled trial using a hybrid design reflecting real-world community care. Among 160 children aged 7–14, CPS was found to be as effective as PMT in reducing ODD symptoms and improving functioning, with gains maintained six months post-treatment. The second study explored treatment acceptability from parents’ perspectives, examining adherence, satisfaction, perceived demands, and therapeutic alliance. Both interventions were rated highly acceptable, though PMT scored slightly higher on some measures. Together, these findings support CPS as a viable, evidence-based, and philosophically aligned alternative to PMT, expanding effective treatment options for families and clinicians.
