OBJECTIVE: Marijuana is the most frequently reported illicit substance used on college campuses. Despite the prevalence, few published intervention studies have focused specifically on addressing high-risk marijuana use on college campuses. The present study evaluated the efficacy of an in-person brief motivational enhancement intervention for reducing marijuana use and related consequences among frequently using college students.

METHOD: Participants included 212 college students from 2 campuses who reported frequent marijuana use (i.e., using marijuana at least 5 times in the past month). Participants completed Web-based screening and baseline assessments and upon completion of the baseline survey were randomized to either an in-person brief intervention or an assessment control group. Follow-up assessments were completed approximately 3 and 6 months post-baseline. Marijuana use was measured by number of days used in the past 30 days, typical number of joints used in a typical week in the last 60 days, and marijuana-related consequences.

RESULTS: Results indicated significant intervention effects on number of joints smoked in a typical week and a trend toward fewer marijuana-related consequences compared with the control group at 3-month follow-up.

CONCLUSION: This study provides preliminary data on short-term effects of a focused marijuana intervention for college students at reducing marijuana use during the academic quarter.

The Warrior Check-Up, a confidential telephone-delivered intervention, is designed to reach active-duty soldiers with untreated substance-use disorder at a large U.S. military base. This paper describes the development and successful implementation of the study's marketing strategies at the recruitment period's midpoint (2010-2012). Qualitative analyses of focus groups (n = 26) and survey responses (n = 278) describe the process of campaign design. Measures of demographics, media exposure, post-traumatic stress, anxiety and depression gathered from callers (n = 172) are used in quantitative analysis assessing the campaign's success in reaching this population. Implications, limitations, and suggestions for future research are discussed. Department of Defense provided study funding.

OBJECTIVE: This study extends previous examinations of social influences and marijuana use in considering how heavy marijuana users view themselves relative to their peers. We were specifically interested in evaluating whether (a) heavy-using marijuana users would identify more strongly with other users than with typical students, (b) identification with other marijuana users would be more strongly associated with own use, and (c) the association between perceived norms and marijuana use would be moderated by identification with peers.

METHOD: Participants were 107 heavy (five or more times per month) marijuana users who completed an online survey assessing perceived norms for marijuana use, identification with typical students and other marijuana-using students, and marijuana use (frequency of use, joints per week, and hours high).

RESULTS: Participants unexpectedly identified more strongly with typical students rather than with other marijuana-using students. Identification with other marijuana users was, however, associated with more use. In addition, perceived norms were associated with more use but primarily among those who identified more with other users but not with typical students.

CONCLUSIONS: Heavy marijuana users may be reluctant to identify themselves as users and may prefer to think of themselves as typical students. This may provide clinical opportunities to highlight discrepancies. In addition, identification with other users and lack of identification with typical students may be risk factors for heavier use and good indicators of candidacy for norms-based interventions. In sum, the present findings extend our understanding of the influence of social identity among young adult marijuana users and suggest novel directions for intervention strategies.

AIMS: The purpose of the current study was to evaluate feasibility and efficacy of two promising approaches to indicated prevention of disordered gambling in a college population.

DESIGN: Randomized clinical trial with assignment to a personalized feedback intervention (PFI), cognitive-behavioral intervention (CBI) or assessment-only control (AOC). PFI was delivered individually in a single session and included feedback regarding gambling behavior, norms, consequences and risk-reduction tips, delivered in a motivational interviewing style. CBI was delivered in small groups over four to six sessions and included functional analysis and brief cognitive correction, as well as identification of and alternatives for responding to gambling triggers.

SETTING: College campus.

PARTICIPANTS: At-risk or probable pathological gamblers (n = 147; 65.3% male; group assignment: PFI, n = 52; CBI, n = 44; AOC, n = 51).

MEASUREMENTS: Self-reported gambling quantity, frequency, consequences, psychopathology, normative perceptions and beliefs.

FINDINGS: Relative to control, results at 6-month follow-up indicated reductions in both interventions for gambling consequences (PFI d = 0.48; CBI d = 0.39) and DSM-IV criteria (PFI d = 0.60; CBI d = 0.48), reductions in frequency for PFI (d = 0.48). CBI was associated with reduced illusions of control, whereas PFI was associated with reduced perceptions of gambling frequency norms. Reductions in perceived gambling frequency norms mediated effects of PFI on gambling frequency.

CONCLUSIONS: A single-session personalized feedback intervention and a multi-session cognitive-behavioral intervention may be helpful in reducing disordered gambling in US college students.

Adolescence is a time in which individuals are particularly likely to engage in health-risk behaviors, with marijuana being the most prevalent illicit drug used. Perceptions of others' use (i.e., norms) have previously been found to be related to increased marijuana use. Additionally, low refusal self-efficacy has been associated with increased marijuana consumption. This cross-sectional study examined the effects of normative perceptions and self-efficacy on negative marijuana outcomes for a heavy using adolescent population. A structural equation model was tested and supported such that significant indirect paths were present from descriptive norms to marijuana outcomes through self-efficacy. Implications for prevention and intervention with heavy using adolescent marijuana users are discussed.

Surprisingly, little is known about how IPV perpetrators perceive the conse quences of their violent behavior. This article describes the development and evaluation of the Perceived Consequences of Domestic Violence Questionnaire (PCDVQ). The PCDVQ is a 27 item self report instrument designed to assess the consequences of intimate partner violence (IPV) as perceived by the perpetrator. Data from 124 nontreatment seeking, male, IPV perpetrators recruited from the community provided support for the internal consistency of the PCDVQ. Participants reported an average of 9.97 (SD = 4.57) consequences. Scores on the PCDVQ significantly predicted motivation for change, beta =.19, t(113) = 2.03, p < .05, and treatment seeking, chi(2)(df = 1) = 10.79, p < .01, odds ratio = 1.27 (95% CI: 1.10 1.46). Clinical implications of this instrument are discussed.

This research was designed to evaluate the applicability of social norms approaches to interventions with male perpetrators of intimate partner violence (IPV). Participants included 124 nonadjudicated IPV perpetrating men recruited from the general population who completed assessment of their own IPV behaviors via telephone interviews and estimated the prevalence of behaviors in other men. Results indicated that IPV perpetrators consistently overestimated the percentage of men who engaged in IPV and that their estimates were associated with violence toward their partner over the past 90 days. Findings provide preliminary support for incorporating social norms approaches into clinical applications.
