  1. T tests were calculated to compare group means
  2. aOne participant’s intelligence could not be evaluated because of the patient’s refusal to take an IQ test, and one participant did not take any medications, so the number of participants contributing to the mean SAPROF internal and motivational scores in the nonviolent group was 83 at 6 months and 77 at 12 months, while that contributing to the mean SAPROF total score in the nonviolent group was 82 at 6 months and 76 at 12 months
