Changes in self-awareness in incarcerated and nonincarcerated male alcoholics are measured before and after disaccustoming therapy based on Alcoholics Anonymous principles. The four-mode conception of self-awareness of Zaborowski is employed. The results show significant and expected changes in incarcerated participants (in defensive, individual, and reflective modes of self-awareness) and almost no changes in nonincarcerated individuals. An effect of motivation on therapy is also identified. Incarceration appears to be more conducive to recovery than to conditions outside the prison.
