Abstract

The purpose of the current study was to conduct a thorough review of the literature on the Interview Informed Synthesized Contingency Analysis (IISCA) developed by Hanley et al. (2014) and its subsequent treatments. A total of 39 articles were identified as including an IISCA to assess the function of participants’ destructive problem behavior. Twenty-nine articles also conducted function-based interventions designed from the results of the IISCAs. Within those 39 studies, 235 participants participated in 293 synthesized contingency analyses (SCA) and 111 treatment evaluations. Results indicated that 95.56% of SCAs in the included studies were reported to be differentiated. Likewise, Tau-U coefficients for 96.14% of graphs were in the moderate to very large effect size range. An omnibus Hedge’s g indicated that the IISCA had a large effect size overall (Hedge’s g= 2.428).

Similarly, reductions in problem behavior were seen in all 111 treatment analyses, with the average percentage of reduction being 97.04% (range 60.28-100%). 98.48% of Tau-U effect sizes for treatment analyses were in the moderate to very large range. In contrast, the omnibus effect size for function-based interventions developed from the results of IISCAs was 2.007, which indicates a large effect size. Results of the current review indicate that the IISCA and function-based interventions developed from the results of IISCA produce statistically significant results. Limitations and future directions are also discussed.
