“…Most of the studies were published in the last decade (n = 24); the remaining studies were published between 1997 and 2010. In 29 studies, a single case design was used (Dunphy & Hens, 2018;Gaskin et al, 2012;Hetzroni & Banin, 2017;Hronis et al, 2019;Kim et al, 2014;;Lancioni, Singh, O'Reilly, Green, et al, 2014;Lancioni, Singh, O'Reilly, Sigafoos, et al, 2014;Perilli et al, 2019;Simacek et al, 2017;Singh et al, 2017;Stasolla et al, , 2015Stasolla et al, , 2017aStasolla, Perilli, Caffò, et al, 2017;. In addition, two studies used a pre-experimental design (Hoffman et al, 2017;Jonker et al, 2015) and one study used a randomized control trial (Cooney et al, 2017), while one study did not report about the study design (Monlux et al, 2019).…”
