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.

A randomized controlled trial is perhaps the only research method which enables researchers to investigate whether cause and effect relationships exist between factors being studied. This article outlines some of the principles underpinning this method and illustrates these with examples taken from an antenatal study of the treatment of women with ...

Comparative effectiveness research generates evidence from observational studies and randomized controlled trials. For many clinical questions, the observational study is an efficient design. Sometimes inherent biases in observational studies yield false results that require refutation by a randomized controlled trial.

Subverting Randomization in Controlled Trials
JAMA: The Journal of the American Medical Association, 1995Recent empirical evidence supports the importance of adequate randomization in controlled trials. Trials with inadequate allocation concealment have been associated with larger treatment effects compared with trials in which authors reported adequate allocation concealment.

Beyond randomized, controlled trials
Current Opinion in Critical Care, 2004Most critical care physicians believe that randomized, controlled trials provide the best available evidence. This review contends that the importance of randomized, controlled trials was overemphasized and that they do not add more to knowledge and practice than physiologic and observational studies.
