Abstract and Keywords

This entry defines Randomized Control Trials (RCTs) and puts them in an historical context. It provides an understanding of the distinction between efficacy and effectiveness RCTs and explains why effectiveness trials are more relevant to social work interventions. The strengths and limitations of RCTs that use experimental designs are delineated. It discusses the reporting requirements of RCTs by the standards of the CONSORT (Consolidated Standards of Reporting Trials).. It also presents the controversies of social workers in the use of RCTs.. Current health services research emphasizes evidence-based practices, research on comparative effectiveness, and using dissemination and implementation research to understand the gaps between empirically supported interventions and the services that are offered in routine care. RCTs have emerged as a central methodology in all of these efforts. Social workers, therefore, need to be knowledgeable and engage in these efforts.

Keywords: comparative effectiveness research, CONSORT, dissemination research, effectiveness trials, experimental design, implementation research, interventions, randomized control trials, randomized field trials
