Rejoinder “Effectiveness in practice-based research: Looking for alternatives to the randomized controlled trial (RCT).” Why and when Randomized Controlled Trials are a necessity

Abstract

Tavecchio’s paper states that RCTs are impractical in the daily practice of social work and public health professionals. He argues that its external validity is limited and that the application of knowledge acquired by stringent application of RCTs takes too long. I believe his arguments are a little off and I shall argue why.
