<str<strong>on</strong>g>The</str<strong>on</strong>g> count model outcomes for violent re<str<strong>on</strong>g>of</str<strong>on</strong>g>fending are presented in Table 2.8.<br />
Again, a zero-inflated negative binomial model proved to be the best fit for our data. 22<br />
Assignment to LIS supervisi<strong>on</strong>, c<strong>on</strong>trolling for other factors, is associated with a small,<br />
n<strong>on</strong>-significant decline in <str<strong>on</strong>g>of</str<strong>on</strong>g>fending over the two-year follow up period than assignment<br />
to the c<strong>on</strong>trol group (IRR = .83, p ≤ .453). <str<strong>on</strong>g>The</str<strong>on</strong>g> <strong>on</strong>ly significant predictor in the full<br />
model is the pre-RA violent <str<strong>on</strong>g>of</str<strong>on</strong>g>fending rate, which is associated with a large decline in the<br />
rate <str<strong>on</strong>g>of</str<strong>on</strong>g> violent re<str<strong>on</strong>g>of</str<strong>on</strong>g>fending (IRR = .34, p ≤ .047). This is surprising because violent<br />
<str<strong>on</strong>g>of</str<strong>on</strong>g>fending history was str<strong>on</strong>gly associated with an increase in the prevalence <str<strong>on</strong>g>of</str<strong>on</strong>g> violent<br />
recidivism. Similarly, gender, which was also associated with increased prevalence <str<strong>on</strong>g>of</str<strong>on</strong>g><br />
re<str<strong>on</strong>g>of</str<strong>on</strong>g>fending, is associated with a decline in <str<strong>on</strong>g>of</str<strong>on</strong>g>fending frequency. Income and probati<strong>on</strong><br />
regi<strong>on</strong>, which were associated with reducti<strong>on</strong>s in overall <str<strong>on</strong>g>of</str<strong>on</strong>g>fending, are associated with<br />
increased frequency <str<strong>on</strong>g>of</str<strong>on</strong>g> violent <str<strong>on</strong>g>of</str<strong>on</strong>g>fending However, it is likely that these results are<br />
skewed by the very small number <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders charged with violent <str<strong>on</strong>g>of</str<strong>on</strong>g>fenses post-RA,<br />
and the wide variati<strong>on</strong> in the number <str<strong>on</strong>g>of</str<strong>on</strong>g> charged <str<strong>on</strong>g>of</str<strong>on</strong>g>fenses. Most <str<strong>on</strong>g>of</str<strong>on</strong>g> the 77 violent<br />
<str<strong>on</strong>g>of</str<strong>on</strong>g>fenders were charged with between <strong>on</strong>e and three crimes, but the count ranges up to 52.<br />
Figure 2.5 shows the comparative Kaplan-Meier survival estimates for violent<br />
<str<strong>on</strong>g>of</str<strong>on</strong>g>fenses in the treatment and c<strong>on</strong>trol groups. <str<strong>on</strong>g>The</str<strong>on</strong>g> graph supports the estimates from the<br />
prevalence and count models. It appears that the probability <str<strong>on</strong>g>of</str<strong>on</strong>g> failure is slightly higher<br />
in the c<strong>on</strong>trol group, and that they fail more quickly than the treatment group (although<br />
note that the scale <strong>on</strong> the y-axis magnifies the size <str<strong>on</strong>g>of</str<strong>on</strong>g> the gap between the two lines). <str<strong>on</strong>g>The</str<strong>on</strong>g><br />
log-rank test indicates no significant difference between the time to failure across the two<br />
groups (χ 2 (1 d.f.) = .69, p ≤ .405). Similarly, when c<strong>on</strong>trolling for other covariates in a<br />
Cox regressi<strong>on</strong> model, we see no difference between the treatment and c<strong>on</strong>trol groups<br />
