Table 7 compares the rates of significant distress as measured by a cut-off of T65 and
T60 when in-patient or out-patient psychiatric norms are used. The rates of offenders
reaching the T65 criteria using these norms are much lower than they are when non-patient
norms are applied. Interestingly, the differences in the percentage of cases that would be
screened in at the T65 cut-off are essentially the same whether one consults the norms on the
psychiatric in-patient or out-patient reference group. Tables 8 and 9 show the breakdown of
the BSI results using inpatient and outpatient norms for Aboriginal and non Aboriginal
offenders. Both Aboriginal and non Aboriginal male federal offenders in this study express
