An analysis relating BSI scores to the dates when the offenders completed the testing
produced a significant negative correlation (r = -.07, p =.02) indicating that those taking the
test later had somewhat lower scores. A correlation this weak indicates that the time during
which the testing was completed, at least within the 90 day window when offenders are at the
reception centres, was not meaningfully related to the level of distress reported by offenders.
Overlap of DHS Scores and GSI. The percentage of offenders scoring above the
chosen cut-off score on the GSI provides the lower end of an estimate of the number of
offenders who will need to be seen for additional screening. To determine whether the
number would increase with the inclusion of the results of the DHS, an analysis of the
overlap in offenders reaching the cut-off for both measures was conducted. Table 15 presents
the results applying the non-patient norms on the BSI. Generally, offenders scoring high on
one scale also score high on the other; in other words, the two scales are in agreement.
