TLDR

Published intervention research to remediate problem behavior provides a major source of empirical evidence regarding standards of practice and the relative effectiveness of intervention strategies. The study proposes recommendations for clinical‑experimental research and publication practices to build a more conclusive evidence base. The authors conducted a meta‑analysis of developmental disabilities literature from 1976 to 1987, using two measures of intervention effectiveness to examine relationships among standards of practice, intervention and participant characteristics, and treatment validity across various excess behaviors. The analysis largely contradicted several widespread assumptions about clinical practice principles.

Abstract

Published intervention research to remediate problem behavior provides a major source of empirical evidence regarding standards of practice and the relative effectiveness of intervention strategies. A meta-analysis of the developmental disabilities literature for the years 1976 through 1987 was performed. Two measures of intervention effectiveness were employed to evaluate the relations between standards of practice, intervention and participant characteristics, and the treatment validity of different levels of intervention for a range of excess behaviors. The results largely failed to support several widespread assumptions regarding precepts of clinical practice. Suggestions were made concerning clinical-experimental research and publication practices to ensure that future work will provide a more conclusive base.
