Modeling year 1 outcomes with treatment process and post-treatment social influences.

Follow-up studies of drug user treatment generally find significant improvements in client functioning, but information about the therapeutic components associated with client behavioral changes over time is limited. An integrative model developed previously to predict treatment retention was expanded and applied to post-treatment outcomes. This study is based on 321 daily opioid users treated in three methadone treatment clinics. Effects of pre-treatment motivation, treatment process measures representing therapeutic relationship, counseling session attendance, and length of treatment are examined in relation to measures of family relations, peer deviancy, return to treatment, drug use, and criminality in the year after treatment. Models were tested in two stages. The first was built on a during-treatment process model for predicting time in treatment to include post-treatment outcomes. The second model was expanded further to include the effects of intervening social support variables as predictors of post-treatment drug and criminality outcomes. The results supported both models and emphasize the importance of considering social influences and related community contextual factors that affect recovery dynamics.

Integrative modeling of client engagement and outcomes during the first 6 months of methadone treatment.

Integrative models containing client and treatment components were tested in a sample of 396 daily opioid users from three methadone maintenance treatment sites. Measures included client motivation at intake as well as repeated assessments of therapeutic engagement (relationships between clients and their counselors, session attendance, and results of urine testing) during the first 6 months of treatment. There was a positive effect of pretreatment motivation on greater engagement and a reciprocal positive relationship between components of engagement and their effects on lowering drug use throughout treatment. Further analyses addressed differential effects of group versus individual counseling and showed that group session attendance was associated with higher rates of drug-negative urines.

Drug abuse treatment process components that improve retention.

BACKGROUND: Longer retention has been the most consistent predictor of favorable drug abuse treatment outcomes, but key therapeutic and patient engagement indicators of treatment process need to be more clearly established. METHODS: An integrative model representing treatment dynamics was tested for explaining long-term program retention. It was based on a multisite sample of 527 daily opioid users who remained in methadone maintenance a minimum of 3 months. All had been assigned randomly to a counseling condition at admission (i.e., cognitively enhanced or standard), and information obtained from patient files, as well as periodic assessments completed by patients and their counselors in the first 90 days after admission were the sources of predictors. RESULTS: Counseling enhancements (using node-link mapping, a visual representation tool for improving communication and problem solving) contributed to stronger therapeutic relationships between counselor and patient, which in turn had a positive reciprocal relationship with patient engagement (session attendance). Pretreatment motivation measured at intake was also related to higher engagement. More positive therapeutic relationships (in months 1 and 2) led to lower levels of during-treatment drug use (defined from urinalysis results in months 2 and 3), and better session attendance and therapeutic relationships both predicted longer retention. In addition, lower drug use during treatment was related to longer retention. CONCLUSIONS: Major conceptual domains of drug abuse treatment process were identified in community-based programs and their interrelationships with retention specified. As intermediate (during treatment) criteria, they can help guide functional improvements in program effectiveness as illustrated with our counseling enhancements.
