There were seven studies employing single-subject research including multiple probe design, ABAB withdrawal design, AB design with regards to quantitative research methods (Aydeniz et al, 2012;Benedek-Wood, Mason, Wood, Hoffman & McGuire, 2014;Helman, Calhoon, & Kern, 2014;Kim & Linan-Thompson, 2013;Seifert & Espin, 2012;Thornton, McKissick, Spooner, Lo, & Anderson, 2015;Wills & Mason, 2014).…”
