A meta-analysis of the single-case research examining the efficacy of Social Story™ interventions for decreasing problem behaviours of children and adolescents with autism spectrum disorder was conducted by examining 27 outcome studies (n = 77) between 1995 and 2012 that yielded 64 intervention effects across three single-case outcome indicators. The overall mean visual analysis ratings and percentage of non-overlapping data scores indicated that the use of Social Story™ interventions resulted in small to negligible effects whereas the weighted effect size estimator ( ES = 0.79) indicated moderate to large treatment effects. Moderator analysis indicated that intervention setting, intervention agent, length of treatment, and publication status were all associated with positive effects for behavioural outcomes, although the significance of these outcomes were not consistent across indicators. Implications for practitioners and clinicians, suggestions for future research, and limitations are discussed.
IntroductionAs the referral and identification rates for autism spectrum disorder (ASD) among children and adolescents continues to rise there is a need to critically evaluate the efficacy of therapies that are intended to treat the social and behavioural symptoms that commonly present to professionals in clinical or educational settings. Although there is no empirically validated "cure" for ASD, many symptoms of the disorder can be effectively managed through a combination of psychoeducational intervention programmes. According to Sansosti, Powell-Smith, and Kincaid (2004), the primary focus of autism interventions is to reduce problem behaviours as well as improve pro-social behaviours that generalise across settings. Some authors (for example, Francis, 2007;Gentry, 2003) have suggested utilising interventions that directly teach social skills and perspective-taking to children with ASD. Social Stories are a flexible intervention strategy that successfully incorporates both of these components. In a recent meta-analysis of school-based social skills interventions for children with ASD, Chenier et al. (2012) found Social Stories to be one of the more popular intervention techniques cited within the empirical literature.
