A comparison of the efficacy of video self-modeling interventions between individuals with disabilities: A meta-analysis of single-case research
The purpose of this dissertation is to fill a need for a meta-analysis of single-subject studies on the effectiveness of video self-modeling (VSM) with broad clinical populations. Although there has been a previous meta-analysis of VSM (Bellini & Akullian, 2007), this analysis was conducted only with studies that utilized participants with autism spectrum disorders. A combination of Kratochwill et al.’s (2010) and Horner et al.’s (2005) suggested coding factors were used to determine the inclusion of studies. A meta-analysis of 14 studies determined the results of VSM across multiple indices. PND and Cohen’s d were used to interpret results. Additional homogeneity analyses and subsequent moderator analyses were conducted. Results showed large evidence for the effectiveness of VSM with broad clinical populations. This dissertation will improve scientific knowledge by way of providing a means of determining if VSM is evidence based for populations other than autism spectrum disorder.
