Table 15 displays the results of the additional Logistic Regression analysis predicting enter- ing AOD treatment without a treatment need variable, including beta values, Wald statistics, alpha values, and odds ratios. Final SOCRATES taking steps scale scores from the drug form remained a significant predictor of entering treatment, and having prior substantiated CPS re- ferrals emerged as a new significant predictor. The odds ratio of 1.56 for the taking steps scale means that for every one point increase in final SOCRATES drug form taking steps scores participants had a 56% increase in their likelihood of entering AOD treatment. The odds ratio of .01 for needing inpatient treatment means that participants who had prior substantiated CPS referrals were 99% less likely to enter AOD treatment.

Out-of-Home Placement and Reunification Models used for predicting both out-of-home placement and reunification had 83 cases available with complete data and had no outlying cases that needed to be exclud- ed from the analyses. Although these models were not as strong as the one predicting AOD treatment entry in terms of classification or explained variance, they were ad- equate and did not depart from an ideal model. The models did not find any significant predictors of out-of-home placement or reunification.

Two additional analyses were conducted substituting the variable of needing inpatient treatment with a variable of needing any treatment at all according to ASAM criteria (0 = No, 1 = Yes). As was the case with the initial out-of-home placement and reunifi- cation analyses, these models were not as strong as the one predicting AOD treatment entry in terms of classification or explained variance, but they were adequate and did not depart from an ideal model. Neither of these two additional models found any significant predictors of out-of-home placement or reunification.
