“…In addition, another study showed a significant relationship between the number of treatment sessions (more than 8) and improvement in psychiatric symptoms (measured with the Child and Adolescent Psychiatric Assessment) at follow-up (Angold, Costello, Burns, Erkanli, & Farmer, 2000). However, other studies reported different findings, including no association between treatment and improved outcomes at followup (J€ org et al, 2012;Zwaanswijk, Verhaak, Van Der Ende, Bensing, & Verhulst, 2006), a very limited association (Trask & Garland, 2012), improvement limited to some subgroups, namely children with low to moderate externalizing problems (Tabone, Thompson, & Wiley, 2010), and even worse mental health outcomes after increased provision of treatment (Yampolskaya, Sharrock, Clark, & Hanson, 2017). A reason for these heterogeneous findings may include a rather crude assessment of treatment, that is, only dichotomized as yes/no treatment (Tabone et al, 2010;Trask & Garland, 2012;Zwaanswijk et al, 2006).…”
