“…At the 6-month follow-up, the parenting program reduced children's externalizing problems as reported by parents, children, and teachers. Follow-up evaluations at 6 years and 15 years found a broad range of benefits, including reductions in mental health problems and disorders, substance use and abuse, and high-risk sexual behavior (Wolchik et al, 2013;Wolchik, Sandler, Weiss, & Winslow, 2007); less involvement in the criminal justice system; and use of mental health services (Herman et al, 2015), as well as improvements in indicators of positive functioning such as self-esteem and grade point average (Wolchik et al, 2007).
