Abstract
Pair-matching in randomized controlled trials (RCTs) has received increased attention in criminology, the social sciences more generally, and medicine and public health, with a growing body of research demonstrating the design's benefits over “simple” RCTs. We carry out a review of matched-pair RCTs compared with simple RCTs to address a somewhat provocative yet fair question for evaluation research on crime and violence prevention interventions: Is it time for the use of pair-matching in all RCTs? At the heart of this question is the ability of the design to most efficiently and robustly compare like with like, thereby, improving confidence in observed effects of intervention trials. Several key findings emerge from the review. First, it is inadequate to examine or discuss RCTs as a single, uniform evaluation design. Here, the key organizing construct is the unit of allocation: individuals; groups of individuals (or clusters); and geographical places. Second, the advantages vastly outweigh the disadvantages for the use of matched-pair RCTs compared to simple RCTs, and most of the advantages hold for all three units of allocation. Third, pair-matching can be used with rather small samples (≥6 units) in cluster-based trials without compromising statistical power or degrees of freedom; less is known about individual- and place-based trials. Fourth, pair-matching cannot be used with some types of RCTs (e.g., cross-over) and is less amenable in other contexts (e.g., RCTs that enroll and randomize individuals on a rolling basis). Implications for evaluation research and public policy are discussed.
期刊介绍:
Aggression and Violent Behavior, A Review Journal is a multidisciplinary journal that publishes substantive and integrative reviews, as well as summary reports of innovative ongoing clinical research programs on a wide range of topics germane to the field of aggression and violent behavior. Papers encompass a large variety of issues, populations, and domains, including homicide (serial, spree, and mass murder: sexual homicide), sexual deviance and assault (rape, serial rape, child molestation, paraphilias), child and youth violence (firesetting, gang violence, juvenile sexual offending), family violence (child physical and sexual abuse, child neglect, incest, spouse and elder abuse), genetic predispositions, and the physiological basis of aggression.
