Multi-protocol treatments are more effective for adults with intellectual and developmental disabilities exhibiting problem behaviors. This review highlights the need for more rigorous research on treatment efficacy and component analysis.
Area of Science:
- Behavioral Psychology
- Developmental Disabilities Research
Background:
- Problem behavior in adults with intellectual and developmental disabilities (IDD) requires effective treatment strategies.
- Existing research offers various therapeutic approaches, necessitating a synthesis of evidence.
Purpose of the Study:
- To systematically review and quantitatively analyze treatment approaches for problem behavior in adults with IDD.
- To compare the efficacy of single-protocol versus multi-protocol treatments.
- To assess the methodological rigor of published research.
Main Methods:
- Quantitative systematic literature review of 76 articles (peer-reviewed and gray literature) from 2002-2022.
- Calculation of effect size estimates (Tau Baseline Corrected).
- Assessment of methodological rigor using a standardized scoring system.
Main Results:
- Identified 42 unique multi-protocol treatments.
- Multi-protocol treatments demonstrated significantly larger effect sizes (greater efficacy) than single-protocol treatments.
- Average methodological rigor scores were low (1.6 for peer-reviewed, 1.2 for gray literature).
Conclusions:
- Multi-protocol interventions show promise for addressing problem behavior in adults with IDD.
- Future research should prioritize rigorous study designs and component analyses to refine treatment strategies.
- Enhancing the methodological quality of research in this field is crucial.
