Note: See text on Page 11 for the definition of Continuous and Non-Continuous Treatment Groups.

The Non-Continuous Treatment group had a greater likelihood of being arrested than did the Continuous Treatment group in the 6-, 12-, and 24-month post-treatment-entry periods, χ2(1) = 7.16 (OR=2.98, 95%CI = 1.34, 6.61), p = .007, χ2(1) = 12.81 OR=3.41, 95%CI = 1.74, 6.68, p < .001, and χ2(1) = 12.17, p < .001 OR=2.81, 95%CI = 1.57, 5.03, respectively.

Mean number of arrests were significantly higher for the Non-Continuous Treatment group than for the Continuous Treatment group in the 6-, 12-, and 24-month post-treatment entry periods, χ2(1) = 8.31, p < .005, χ2(1) = 13.21, p < .001, and χ2(1) = 14.65, p < .001, respectively.
