“…To address the concern that the findings of negative outcomes associated with spanking in past research were a result of the confounding of spanking with overly harsh or potentially abusive methods, we identified seven studies that reported bivariate associations for both spanking and physical abuse. The latter was defined variously as “hitting with fist or object, beating up, kicking, or biting” (Bugental, Martorell, & Barraza, 2003), “beaten to injury” (Lau, Chan, Lam, Choi, & Lai, 2003), “been injured from a beating” (Lau et al, 2005), “frequent or severe physical punishment” (Fergusson, Boden, & Horwood, 2008), “use of a weapon, punching, or kicking” (Lynch et al, 2006), “severe physical assault” (Miller-Perrin, Perrin, & Kocur, 2009), and “physical abuse leading to bruising” (Schweitzer, Zavar, Pavlicova, & Fallon, 2011). Each of these studies employed a within-subjects design; in each case, the same respondent (either a parent or the adult child recalling the behavior) reported both how often the parent used spanking and, in a separate question, how often the parent used abusive methods of discipline.…”
