摘要

A strong theme in the social work literature contends that randomized experiments are an impractical, inappropriate, unethical, and rarely undertaken research method for use in social work. In a test of this claim, the author undertook a review of the English-language published literature and prepared a provisional bibliography of primary social work studies that used experimental methodology. Astonishingly, over 740 such studies were located, with the first being published in 1949. The existence of this large experimental social work literature has been largely unrecognized, in part, because much of it has appeared in a diverse array of journals associated with other disciplines. It is no longer tenable to claim that experiments are either impractical or inappropriate as a social work research method of value in making causal inferences. This bibliography will be amended in coming years, and subsequent analyses of the types of problems and interventions, which are the focus of these studies, will add to the empirical foundations of social work practice.
