Knowledge Item: CA-Psychosocial Services-25
Models Linking Receipt of Psychosocial Services to Drug Abuser Status

A series of logistic regression analyses were used to show whether current and prior drug abusers were more or less likely to receive 39 kinds of services during their service episodes than individuals not identified as drug abusers. The individual analyses control for project (site), gender, days in the program, and status as active in the program on the last day of data collection.

The following table summarizes the 39 logistic regression analyses by showing, for each type of service ever received during the service episode in the SPNS project studied here, whether the likelihood of receiving the service was significantly higher for prior users (as compared to individuals not identified as drug abusers); for current drug abusers users (as compared to individuals not identified as drug abusers); and for women (as compared to men). If an odds shown below are greater than 1.0, that type of person is that many times more likely to get the service than the comparison group. If an odds shown below are less than 1.0, then that type of person is that much less likely to get the service than the comparison group. Odds can be as small as .001 and as large as "infinity" although numbers larger than about 10 are not typical. Significance tests are also shown for the odd reported in the table. The individual analyses control for project (site), gender, days in the program, and status as active in the program on the last day of data collection. Consider the first row of the table. Current drug abusers are almost twice as likely as individuals not identified as drug abusers to receive an HIV risk assessment during their treatment episode. Whether drug abusers or not, women are about half as likely as men to receive such an assessment.
