“…However, the limited empirical research on supervision is primarily descriptive or exploratory in nature (Hoge et al, 2011), despite findings from one study that suggest that supervision may account for 16% of the variance in client treatment outcomes—approximately double the amount commonly attributed to specific treatment interventions (8%; Callahan, Almstrom, Swift, Borja, & Heath, 2009). There also is increasing theoretical (Nadeem et al, 2013) and empirical work on a related, but distinct area, EBT-focused expert consultation (e.g., Bearman et al, 2013; Beidas, Edmunds, Marcus, & Kendall, 2012; Funderburk et al, 2015). While this is an important area of research, expert consultation is a costly resource (Herschell et al, 2010; Stewart et al, 2016), whereas providing clinical supervision of EBT through workplace-based supervision, utilizing existing supervisory staff, may provide a cost-effective, feasible alternative.…”
