Investigated alienation by administering Dean Alienation Scale to 157 incarcerated and 1,318 nonincarcerated adolescents. Found that incarcerated adolescents had significantly higher levels of total alienation, isolation, and powerlessness. Given high recidivism rates, results suggest reduction of both alienation and rejection of societal norms should be major component of rehabilitation programs for incarcerated juvenile delinquents.
