A randomized trial of brief interventions for problem and pathological gamblers.

Limited research exists regarding methods for reducing problem gambling. Problem gamblers (N = 180) were randomly assigned to assessment only control, 10 min of brief advice, 1 session of motivational enhancement therapy (MET), or 1 session of MET plus 3 sessions of cognitive-behavioral therapy. Gambling was assessed at baseline, at 6 weeks, and at a 9-month follow-up. Relative to assessment only, brief advice was the only condition that significantly decreased gambling between baseline and Week 6, and it was associated with clinically significant reductions in gambling at Month 9. Between Week 6 and Month 9, MET plus cognitive-behavioral therapy evidenced significantly reduced gambling on 1 index compared with the control condition. These results suggest the efficacy of a very brief intervention for reduction of gambling among problem and pathological gamblers who are not actively seeking gambling treatment.

Internet Gambling Is Common in College Students and Associated with Poor Mental Health

This study evaluated prevalence of Internet gambling and its association with pathological gambling and mental health status in college students. The South Oaks Gambling Screen and General Health Questionnaire were administered to 1356 undergraduates, and 23% reported ever gambling on the Internet, with 6.3% reporting Internet gambling weekly. Almost two-thirds (61.6%) of regular Internet gamblers were pathological gamblers, compared with 23.9% of infrequent Internet gamblers and 5.0% of non-Internet gamblers. Internet gambling frequency was significantly associated with poor mental health, after controlling for demographics and pathological gambling. These data call for prevention and treatment efforts of Internet gambling in students.

Behavioral Assessment of Gambling: An Application of the Timeline Followback Method.

The Gambling Timeline Followback (G-TLFB), a measure of gambling behavior that uses the timeline followback methodology, was psychometrically evaluated with samples of frequent-gambling young adults. Seven dimensions of gambling behavior were assessed: type, frequency, duration, intent, risk, win-loss, and consumption of alcohol while gambling. The G-TLFB demonstrated adequate to excellent test-retest reliability with a sample of 57 frequent gamblers (r=.75 to.96) and with a group of 34 disordered gamblers (r=.73 to.93). With a separate sample of 58 frequent-gambling participants, convergent, concurrent, and discriminant validity were assessed. The G-TLFB correlated positively with daily self-monitoring reports (r=.59 to.87). The dimensions of frequency and duration demonstrated concurrent validity with gambling screening instruments, and standard drinks consumed while gambling demonstrated concurrent validity with a measure of alcohol misuse. The G-TLFB also demonstrated discriminant validity with demographic variables and a measure of positive impression management.

Exercise-related activities are associated with positive outcome in contingency management treatment for substance use disorders.

Exercise has been proposed as an adjunct intervention for substance use disorders due to its many benefits in terms of mental and physical health. This study investigated the association between completion of exercise-related activities and substance use disorders treatment outcome in a sample of 187 participants undergoing intensive outpatient treatment with contingency management. The sample was divided into two groups based upon whether or not an individual completed an exercise-related activity. Individuals who engaged in exercise-related activities (n=45) were found to achieve longer durations of abstinence during treatment than individuals who did not complete an exercise-related activity (n=142). Overall, these findings suggest that exercise may be of benefit to individuals undergoing substance use disorders treatment. Methods for implementing an exercise intervention within substance use disorders treatment are discussed.

Brief motivational interventions for college student problem gamblers.

AIMS College students experience high rates of problem and pathological gambling, yet little research has investigated methods for reducing gambling in this population. This study sought to examine the efficacy of brief intervention strategies. DESIGN Randomized trial. SETTING College campuses. PARTICIPANTS A total of 117 college student problem and pathological gamblers. INTERVENTIONS Students were assigned randomly to: an assessment-only control, 10 minutes of brief advice, one session of motivational enhancement therapy (MET) or one session of MET, plus three sessions of cognitive-behavioral therapy (CBT). The three interventions were designed to reduce gambling. MEASUREMENTS Gambling was assessed at baseline, week 6 and month 9 using the Addiction Severity Index-gambling (ASI-G) module, which also assesses days and dollars wagered. FINDINGS Compared to the assessment-only condition, those receiving any intervention had significant decreases in ASI-G scores and days and dollars wagered over time. The MET condition decreased significantly ASI-G scores and dollars wagered over time, and increased the odds of a clinically significant reduction in gambling at the 9-month follow-up relative to the assessment-only condition, even after controlling for baseline indices that could impact outcomes. The Brief Advice and MET+CBT conditions had benefits on some, but not all, indices of gambling. None of the interventions differed significantly from one another. Conclusions These results suggest the efficacy of brief interventions for reducing gambling problems in college students.

Group-Based Randomized Trial of Contingencies for Health and Abstinence in HIV Patients

OBJECTIVE Contingency management (CM) treatments are usually applied individually for drug abstinence, but CM can also be targeted toward health behaviors and implemented in groups. This study evaluated effects of a group-based CM intervention that focused on reinforcing health behaviors. METHOD HIV-positive patients with cocaine or opioid use disorders (n = 170) were randomized to weekly CM or 12-step (TS) groups for 24 weeks (mean attendance was 10.8 +/- 8.1 sessions for CM participants and 9.0 +/- 6.9 session for TS participants). During the treatment period, both groups received compensation for attendance (

During the treatment period, patients in the CM group received chances to win prizes contingent upon completing health activities and submitting substance-free specimens (M =
