Abstract
Despite the established efficacy of Parent Management Training (PMT) for conduct problems in youth, evidence suggests that up to half of all treated youth still display clinical levels of disruptive behavior post-treatment. The reasons for these unsatisfactory outcomes are poorly understood. The aim of the present review was to provide an updated analysis of studies from the past 15 years that examined parental and familial predictors and moderators of improvement in PMT for conduct problems. A systematic literature review of indicated prevention (children with conduct problem symptoms) and intervention (children with clinical diagnoses) studies published between 2004 and 2019 was conducted. This 15-year time period was examined since the last systematic reviews were reported in 2006 and summarized studies completed through mid-2004 (see Lundahl et al. in Clin Psychol Rev 26(1):86–104, 2006; Reyno and McGrath in J Child Psychol Psychiatry 47(1):99–111, 2006). Risk of bias indices was also computed (see Higgins et al. in Revised Cochrane risk of bias tool for randomized trials (RoB 2.0), University of Bristol, Bristol, 2016) in our review. A total of 21 studies met inclusion criteria. Results indicated that a positive parent–child relationship was most strongly associated with better outcomes; however, little additional consistency in findings was evident. Future PMT research should routinely examine predictors and moderators that are both conceptually and empirically associated with treatment outcomes. This would further our understanding of factors that are associated with poorer treatment outcome and inform the development of treatment components or modes of delivery that might likely enhance evidence-based treatments and our clinical science.
