A meta-analysis of the single-case research examining the efficacy of Social StoryTM 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 StoryTM 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.
