A recent study, "[b]ased on data from a survey of nearly 1,500 Boston men aged 18 to 35 years...found that 16 percent of the men - about one in six -- said they had abused their partner physically or sexually within the past year. Of those who admitted to recent abuse, 38 percent said they had bullied their peers frequently in school. That compared to only 12 percent of the men who hadn't maltreated their partner as adults" ("School Yard Bullies More Likely to Abuse Partners," 2011, June 6). The study concluded, after eliminating other variables such as child abuse, that "frequent bullying as a kid was linked to a four-fold increase in a man's risk for partner abuse" ("School Yard Bullies More Likely to Abuse Partners," 2011, June 6). Discuss this study. Is the result plausible?
