“…As of April 25, 2018, our search yielded 21 studies consisting of 12 nonoverlapping samples (see the appendix). The vast majority of studies were produced in English ( k = 18), and two studies were in German (Eher et al, 2013; Rettenberger, Matthes, Schilling, & Eher, 2011). Six studies reported on nonoverlapping samples, one study (Looman & Goldstein, 2015) contained two different samples that were divided into a routine and a high-risk/need sample, and a further 13 studies represented four overlapping samples, resulting in 12 unique samples.…”
