long time to complete, making it difficult to examine whetherbehavioral or pharmacological manipulations could be used todecrease choices deemed impulsive. The rapid delay-discountingprocedure used in this experiment was successful at obtainingorderly discounting functions in a relatively short period of time,making this procedure potentially useful for examining effects ofbehavioral and pharmacological treatments on delay discounting.

Behavioral incentives to promote exercisecompliance in cocaine-dependent women

Aims: Low rates of patient compliance have made studyingthe benefits of regular exercise on women with substance usedisorders (SUD) impractical. Contingency management (CM is)strategy for promoting behavior change, which has been success-ful in reinforcing behaviors such as drug abstinence and treatmentattendance. CM offers incentives (prizes) contingent upon targetbehaviors. Due to expense, CM is often delivered with an escalatingvariable ratio schedule (Petry et al., 2005). As a Stage Ib behavioraltherapies development project (Rounsaville et al., 2001), the pri-mary aim was to test behavioral incentives (BI) to promote regularphysical activity in cocaine-dependent women in residential SUDtreatment. The target was physical activity, defined as: 30 minutesof treadmill walking (any pace) and treadmill walking (moderateintensity).

Methods: A pilot RCT compared physical activity rates oversix weeks in women with Cocaine Dependence randomized to BI(n = 10) or control (C, n = 7) groups. All participants completed base-line assessments, attended a 45-minute health/fitness educationclass, and were scheduled to exercise three days/week. BI par-ticipants were eligible three days/week, to receive incentives formeeting the target behavior(s). Follow-up assessment occurred at3- and 6-weeks post-randomization, and 4-weeks post-dischargefrom the residential program. The primary outcome variables (% ofsessions completed and total time in sessions) were used for effectsize estimations, which were used for power analyses to estimatesample size for Stage II of a RCT.

Results: A significant group effect demonstrated the BI groupspent more minutes in scheduled exercise sessions than the Cgroup. Results provide benchmark data on the use of BI to promotephysical activity in cocaine-dependent women.

Conclusions: Findings support BI to promote exercise compli-ance, which can inform development of SUD programs that directlyutilize the mental and physical health benefits of physical activity.

Model minority stereotype, psychologicaldistress, substance use among Asian-Americanyoung adults

Aims: Risk behaviors including substance use, are a growingproblem among U.S.-born Asian American young adults, however,the determinants underlying this trend are poorly understood. Onedistinct factor for U.S.-born Asian Americans that may increaserisk behavior is the endorsement of the “model minority” stereo-type. Based on the negative affect regulation theory endorsing the“positive” stereotype of the model minority (i.e., the belief that allAsians are high academic achievers and financially well-off) mayheighten psychological distress and, in turn, confer risk for prob-lem drinking. The aim of this study is to examine the role of theendorsement of the model minority stereotype, psychological dis-tress, illicit drug use (e.g., marijuana use, non-prescription drugs)and alcohol-related problems among Asian American young adults.

Methods: Participants included 162 U.S-born Asian Americanyoung adults recruited from the Maryland and Washington, DCarea. Participants completed a measure of endorsement of themodel minority stereotype (two subscales: (1) achievement orien-tation or the myth that Asian American’s success is due to strongerwork ethic and drive for success, and (2) unrestricted mobility orthe myth that this group experiences less perceived racism andbarriers at work), psychological distress and substance use.

Results: Rates of alcohol-related problems and illicit drug useappear to be higher in the current sample, compared to previousstudies. Structural equation modeling results suggest that the twomodel minority stereotype scales had an indirect effect on alcohol-related problems and illicit drug use through psychological distressand heavy episodic drinking.

Conclusions: Asian American young adults are increasinglybecoming an at-risk group for risk behaviors including alcohol-related problems and illicit drug use. Endorsing the “positive”model minority stereotype appears to be a risk factor for alcoholrelated problems and illicit drug use by heightening psychologicaldistress, which supports the negative affect regulation framework.

Aims: The study assessed the proportion of opioid overdose andpoisoning (OOP) events identified by ICD diagnostic codes in elec-tronic medical records that were true OOP events as confirmedby medical chart review (i.e., the positive predictive value of ICDcodes). Accurate identification of OOP events is essential if dataare to be used to assess population risk, care quality, or evaluatepreventive interventions.
