“…Over the past 30 years, research has advanced the treatment of serious mental health disorders during childhood and adolescence such as depression, anxiety, and disruptive behavior disorders (Hoagwood et al, 2014; Mufson & Moreau, 1999). However, few research-supported treatments (RSTs) reach children in need (Marques et al, 2016; Park, Moskowitz, & Chorpita, 2018; Ringle et al, 2015). Beyond access issues-an oft cited statistic suggests that up to 65% of children and adolescents with serious mental health problems never access the mental health service system (Agency for Healthcare Research and Quality, 2010), and 60% of youth who initially engage in treatment drop out prematurely (Gopalan et al, 2010), RSTs are not commonly available in real-world community mental health settings (Marques et al, 2016).…”
