In his recent "Crime and Coercion," Colvin contends that individuals exposed to coercive environments develop social-psychological deficits that enhance their probability of engaging in criminal behavior. Using a sample of 2,472 students from six middle schools, the authors test core propositions of Colvin's differential coercion theory. Thus, they assess whether delinquent involvement is related to four coercive environments: parental coercion, peer coercion, a coercive school environment, and a coercive neighborhood environment. The authors also assess whether the influence of these coercive environments on delinquency is mediated by four social-psychological deficits: coercive ideation, anger, school social bonds, and parental social bonds. The analysis revealed fairly consistent support for the core propositions of differential coercion theory. Thus, they found that students exposed to coercive environments develop social-psychological deficits and therefore engage in relatively serious delinquent behavior. (Contains 2 tables and 6 notes.)
