Randomized Controlled Trial Multicenter StudyReasons for opioid use among patients with dependence on prescription opioids: the role of chronic pain.
The number of individuals seeking treatment for prescription opioid dependence has increased dramatically, fostering a need for research on this population. The aim of this study was to examine reasons for prescription opioid use among 653 participants with and without chronic pain, enrolled in the Prescription Opioid Addiction Treatment Study, a randomized controlled trial of treatment for prescription opioid dependence. ⋯ Participants with chronic pain rated using opioids to cope with physical pain as more important, and using opioids in response to social interactions and craving as less important, than those without chronic pain. Results highlight the importance of physical pain as a reason for opioid use among patients with chronic pain.

Randomized Controlled Trial Multicenter StudyGender differences in a clinical trial for prescription opioid dependence.
Although gender differences in substance use disorders have been identified, few studies have examined gender differences in prescription drug dependence. The aim of this study was to examine gender differences in clinical characteristics and treatment outcomes in a large clinical trial for prescription opioid dependence. Despite no pre-treatment differences in opioid dependence severity, women reported significantly greater functional impairment, greater psychiatric severity, and higher likelihood of using opioids to cope with negative affect and pain than men. ⋯ Men reported significantly more alcohol problems than women. There were no significant gender differences in medication dose, treatment retention, or opioid outcomes. Thus, despite the presence of pre-treatment gender differences in this population, once the study treatment was initiated, women and men exhibited similar opioid use outcomes.

Randomized Controlled Trial Multicenter StudyImpulsivity is associated with treatment non-completion in cocaine- and methamphetamine-dependent patients but differs in nature as a function of stimulant-dependence diagnosis.
Greater impulsivity, assessed by the Barratt Impulsiveness Scale-11 (BIS-11) and Stroop interference scores, has been associated with treatment completion in cocaine-dependent patients. This study evaluated the relationships among impulsivity, stimulant-dependence diagnosis, and treatment completion. Six sites evaluating 12-step facilitation for stimulant abusers obtained the BIS-11 and Stroop from 182 methamphetamine- and/or cocaine-dependent participants. ⋯ There was a trend for poorer response inhibition, measured by the Stroop, in cocaine-dependent, relative to methamphetamine-dependent, participants. Accounting for other factors related to treatment completion, BIS-11 motor score, assessing the tendency to act without thinking, predicted treatment completion for both cocaine-dependent and methamphetamine-dependent patients. These results suggest that methamphetamine-dependent and cocaine-dependent patients may have different impulsivity profiles but that the BIS-11 may be useful in identifying both methamphetamine-dependent and cocaine-dependent patients who are at risk for treatment non-completion.

Multicenter StudyAccess to treatment-related and support services in methadone treatment programs.
This study examines whether the mechanism through which a methadone maintenance treatment site offers seven treatment-related and support services is related to whether a patient receives such services. Mechanisms include the provision of services on-site, at another program site, or through formal or informal linkage arrangements. ⋯ Providing services on-site was found to be positively related to patient access to a majority of services, whereas, in general, offering services at another program site or through formal or informal linkages was not found to be effective. Not-for-profit or public ownership of treatment sites was also found to be positively related to patient access.

Multicenter Study Comparative StudyRetention of homeless clients in substance abuse treatment. Findings from the National Institute on Alcohol Abuse and Alcoholism Cooperative Agreement Program.
Retaining clients in treatment who are homeless presents a particular challenge for substance abuse treatment providers. A National Institute on Alcohol Abuse and Alcoholism Cooperative Agreement Program offered the first opportunity to systematically study program retention in a multisite study of interventions for homeless persons with alcohol and other drug problems. ⋯ Key findings were that (a) retention problems with homeless clients are as or more pervasive than in the general addicted population; (b) the provision of housing increases retention, but the increases tend to be nullified when the housing is bundled with high-intensity services; (c) homeless clients leave treatment programs for a multitude of reasons; and (d) midcourse corrections to increase retention are frequently successful. The discussion focuses on service components related to retention, the importance of attending to phase transitions, and the importance of being programmatically responsive when serving this population.
