“…However, despite their widespread use, very little rigorous, well-designed research
has been conducted to examine their efficacy (Kasari, Shire, Factor, & McCracken, 2014). Indeed, while there
have been more than a dozen systematic reviews of GSSIs conducted in recent years
(e.g., Barry et al, 2003; Blacher, Kraemer, & Schalow, 2003; Elder, Caterino, Chao, Shacknai, & De Simone,
2006; Flynn & Healy, 2012;
Kaat & Lecavalier, 2014; Kasari & Patterson, 2012; Koenig, De Los Reyes, Cicchetti, Scahill, &
Klin, 2009; McMahon, Lerner et al,
2013; Miller, Vernon, Wu, &
Russo, 2014; Otero, Schatz, Merrill,
& Bellini, 2015; Rao, Beidel,
& Murray, 2008; Reichow &
Volkmar, 2010; Schreiber, 2011;
Spence, 2003; White, Keonig, & Scahill, 2007), there has only been
one meta-analysis to evaluate efficacy of GSSIs (Reichow, Steiner, & Volkmar, 2012). This sole meta-analysis
– which focused on well-designed randomized controlled trials (RCTs) with a
wait-list control, of which only five were evident at the time – provided
initial support for the efficacy of GSSIs for improving social competence for ASD
youth.…”
