A group Motivational Interviewing intervention reduces drinking and alcohol-related negative consequences in adjudicated college women

Peer crowd affiliations as predictors of prosocial and risky behaviors among college students

ObjectivesTo examine college peer crowd affiliations and prosocial and risky behaviors (academic, sexual, drug, and alcohol related risks) as well as to investigate gender as a moderator of these relations. Participants: 527 students at a public university in the Midwest in Fall 2018 (M age = 19.67, SD = 1.84). Method: Students' peer crowd affiliations were reported using an online survey. Four peer crowd dimensions were confirmed using Factor Analysis: Social (popular partiers and Greek organization members), Athletic, Arts/Diverse (students identifying strongly with a countercultural group, their race/ethnic group, and/or performing arts); and Scholastic (academic achievement and leadership). Results: Social crowd affiliations positively predicted all risk-related behaviors. Social and Scholastic affiliations positively predicted prosocial behaviors. Finally, gender significantly moderated the relations between peer crowd affiliations and risk and prosociality. Conclusions: These findings demonstrate that peer crowd affiliation and gender are important when promoting positive behaviors on campus.

Dissemination of a Universally Delivered Brief Alcohol Intervention in United States Air Force Technical Training

OBJECTIVES

Heavy alcohol use is a particular problem in the US military, prompting the Institute of Medicine to identify it as a public health crisis. Developing prevention programs aimed at reducing problematic drinking during military service would be useful. Thus, the purpose of the current study, was to broadly disseminate and assess the effectiveness of a brief alcohol intervention (BAI) + random breathalyzer (RB) intervention to reduce alcohol related incidents (ARIs), to all incoming Air Force trainees.

METHODS

The BAI was administered to all incoming Airmen (N = 15,898) across 4 major training Air Force bases. Additionally, underage Airmen were subject to RB tests. A quasi-experimental pre-test post-test design compared the rate of ARIs, per 100,000 training days, during the year prior and the year after the intervention was delivered.

RESULTS

A Poisson model indicated that the BAI + RB intervention was associated with a decrease in ARIs across all bases. Overall, the intervention lowered the ARI rate by 16% (β = -0.178, standard error  = 0.0742, P = 0.016). For every 100,000 training days, annual ARIs decreased from 30.8 to 25.5 after implementation.

CONCLUSIONS

A universally administered brief alcohol intervention, coupled with RB targeting underage drinkers, was associated with a reduction in the rate of ARIs. Results of this large-scale prevention study indicate that a brief alcohol intervention can be widely disseminated during US Air Force training and can perhaps reduce costs and make a public health contribution by decreasing alcohol related incidents.

Randomized controlled trial of group motivational interviewing for veterans with substance use disorders

BACKGROUND

Motivational interviewing delivered in a group format is understudied yet promising as a treatment for substance use disorders (SUD). We evaluated the efficacy of group motivational interviewing (GMI) relative to a treatment-control (TCC) for enhancing treatment and self-help engagement and decreasing alcohol and drug use among veterans with SUD and co-existing psychiatric disorders.

METHOD

Veterans (n = 118) with alcohol use disorder were recruited within an outpatient SUD treatment program and randomized to GMI or TCC upon program entry. Alcohol use, SUD treatment, and 12-step session attendance were primary outcomes. Drug use days was the secondary outcome. Participants were assessed at baseline and at one-and three-month follow-up.

RESULTS

Significant differences were observed between GMI and TCC for binge drinking at both one (RR = .74; 95 % CI [.58, .94]) and three-month follow-up (RR = .74; 95 % CI [.59, .91]). At three-month follow-up, significant differences between treatment conditions were observed for alcohol use days (RR = .79; 95 % CI [.67, .94]), number of SUD treatment sessions (RR = 2.53; 95 % CI [1.99, 3.22]), and 12-step sessions attended (RR = 1.64; 95 % CI [1.35-1.98]). Similarly, we observed significant effects for GMI on reducing alcohol consumption in standard drinks (RR = .49; 95 % CI [.25, .95]). Drug use days declined at each follow-up, with no significant differences between treatment conditions.

CONCLUSIONS

GMI delivered at SUD treatment program entry enhanced treatment session and 12-step group attendance and lowered alcohol consumption among outpatient Veterans. Future research should study how GMI works and its effectiveness in SUD treatment settings.

Evaluation of a Pilot Healthy Eating and Exercise Program for Young Adults with Autism Spectrum Disorder and Intellectual Disabilities

OBJECTIVES

The aims of this pilot study were to examine program structure, implementation, and outcomes of a healthy eating and exercise program for young adults with Autism Spectrum Disorder (ASD) and intellectual disabilities (IDs).

METHODS

Seventeen young adults with ASD and IDs, six parents, and 10 staff participated. Programming was delivered for over a year and featured healthy eating and exercise lessons. Also, group-based motivational interviewing was used to develop weekly health goals for participants. During COVID-19, lessons were delivered online. The program was modified using lectures with visual material, when participants returned to classrooms. Lessons focused on MyPlate, portion sizes, the food pyramid, vitamins and minerals in foods, and learning to eat "less" of unhealthy food groups. Exercise lessons featured information about importance of exercise, introduction to different types of exercise, and knowledge about how exercise benefits the body. Staff completed implementation logs. Height and weight of participants were examined at regular intervals. Parents completed surveys and participants completed group interviews to assess program impact.

RESULTS

Two participants lost a significant amount of weight and others maintained their weight during COVID-19. Participants and parents were satisfied with the program and reported knowledge and behavior change.

CONCLUSIONS

Results indicated participating in the intervention resulted in improved knowledge and health behaviors. Findings are preliminary, and research using control groups and assessing change in weight and behaviors over time are needed. Observation of meals and physical activity levels will provide more objective data in future studies.

Examining the Effects of a Brief, Group-Based Motivational Implementation Strategy on Mechanisms of Teacher Behavior Change

Training and consultation are core implementation strategies used to support the adoption and delivery of evidence-based prevention programs (EBPPs), but are often insufficient alone to effect teacher behavior change. Motivational interviewing (MI) and related behavior change techniques (e.g., strategic education, social influence, implementation planning) delivered in a group format offer promising supplements to training and consultation to improve EBPP implementation. Beliefs and Attitudes for Successful Implementation in Schools for Teachers (BASIS-T) is a theoretically informed, motivational implementation strategy delivered in a group format prior to and immediately after EBPP training. The purpose of this study was to examine the proximal effects of BASIS-T on hypothesized mechanisms of behavior change (e.g., attitudes, subjective norms, intentions to implement) in the context of teachers receiving training and consultation to implement the Good Behavior Game. As part of a pilot trial, 83 elementary school teachers from 9 public elementary schools were randomly assigned (at the school-level to reduce contamination across participants) to a BASIS-T (n = 44) or active comparison control (n = 39) condition, with both conditions receiving Good Behavior Game (GBG) training and consultation. A series of mixed effects models revealed meaningful effects favoring BASIS-T on a number of hypothesized mechanisms of behavior change leading to increased motivation to implement GBG. The implications, limitations, and directions for future research on the use of MI with groups of individuals and other behavior change techniques to increase the yield of training and consultation are discussed.

Gender Informed or Gender Ignored? Opportunities for Gender Transformative Approaches in Brief Alcohol Interventions on College Campuses

Brief alcohol interventions are an effective strategy for reducing harmful and risky alcohol use and misuse. Many effective brief alcohol interventions include information and advice about an individual's alcohol use, changing their use, and assistance in developing strategies and goals to help reduce their use. Emerging research suggests that brief interventions can also be expanded to address multiple health outcomes; recognizing that the flexible nature of these approaches can be helpful in tailoring information to specific population groups. This scoping review synthesizes evidence on the inclusion of sex and gender in brief alcohol interventions on college campuses, highlighting available evidence on gender responsiveness in these interventions. Furthermore, this scoping review offers strategies on how brief alcohol interventions can be gender transformative, thereby enhancing the effectiveness of brief alcohol interventions as harm reduction and prevention strategies, and in promoting gender equity.

Design and feasibility testing of a novel group intervention for young women who binge drink in groups

BACKGROUND

Young women frequently drink alcohol in groups and binge drinking within these natural drinking groups is common. This study describes the design of a theoretically and empirically based group intervention to reduce binge drinking among young women. It also evaluates their engagement with the intervention and the acceptability of the study methods.

METHODS

Friendship groups of women aged 18-35 years, who had two or more episodes of binge drinking (>6 UK units on one occasion; 48g of alcohol) in the previous 30 days, were recruited from the community. A face-to-face group intervention, based on the Health Action Process Approach, was delivered over three sessions. Components of the intervention were woven around fun activities, such as making alcohol free cocktails. Women were followed up four months after the intervention was delivered.

RESULTS

The target of 24 groups (comprising 97 women) was recruited. The common pattern of drinking was infrequent, heavy drinking (mean consumption on the heaviest drinking day was UK 18.1 units). Process evaluation revealed that the intervention was delivered with high fidelity and acceptability of the study methods was high. The women engaged positively with intervention components and made group decisions about cutting down. Twenty two groups set goals to reduce their drinking, and these were translated into action plans. Retention of individuals at follow up was 87%.

CONCLUSIONS

This study successfully recruited groups of young women whose patterns of drinking place them at high risk of acute harm. This novel approach to delivering an alcohol intervention has potential to reduce binge drinking among young women. The high levels of engagement with key steps in the behavior change process suggests that the group intervention should be tested in a full randomised controlled trial.

A Novel Approach for Streamlining Delivery of Brief Motivational Interventions to Mandated College Students: Using Group and Individual Sessions Matched to Level of Risk

BACKGROUND

Mandated college students (those in violation of a campus alcohol policy) are heterogenous with respect to alcohol consumption. Thus, when universities consider required treatment for mandated students, one promising option is to match treatment intensity according to level of alcohol involvement. The present study evaluates such an approach with minimal resources.

METHODS

Mandated students (N = 285) were required to complete a baseline assessment. Participants identified as high-risk (5+ past month alcohol problems AND 2+ past month heavy drinking episodes) received a one session individual Brief Motivational Intervention (I-BMI) whereas those identified as low-risk (all others) received a one session group Brief Motivational Intervention (G-BMI). I-BMI and G-BMI sessions were delivered by doctoral students in Clinical Psychology. Follow-up assessments were collected 1 month post-intervention (response rate = 73%).

RESULTS

The vast majority of students complied with their requirement. Participants assigned to I-BMI reported an 82% reduction in drinks per week, a 58% reduction in heavy episodic drinking, and a 74% reduction in alcohol-related problems at a 1 month follow-up. Participants assigned to G-BMI reported a 61% reduction in drinks per week and a 42% reduction in alcohol-related problems at follow-up relative to baseline. Conclusion/Importance: We demonstrate that matching intervention intensity on baseline alcohol involvement with mandated students is feasible and associated with short-term reductions in alcohol use and consequences. Universities may wish to consider the procedure outlined here as a way of allocating more resources to those who drink at problematic levels.

Family-centered brief intervention for reducing obesity and cardiovascular disease risk: A randomized controlled trial

OBJECTIVE

To assess the effects of a family-centered, physical activity and nutrition "brief" intervention (time-limited contact) on body weight and related health outcomes in primary health care patients with an elevated 5-year cardiovascular disease (CVD) risk.

METHODS

This study implemented a cluster randomized controlled trial design with two treatment conditions: a CVD risk assessment and one-time consultation ("usual care" control) and a CVD risk assessment and up to five home sessions that aimed to reduce obesity by encouraging physical activity and healthy eating (intervention). Three hundred and twenty patients aged 35 to 65 years from 16 primary health care clinics in Auckland, New Zealand, participated in the study. Intervention effects on BMI, waist circumference, blood pressure, blood cholesterol, triglycerides, 5-year CVD risk, physical activity, and dietary patterns were assessed using generalized linear mixed models.

RESULTS

When compared with the control group, the intervention resulted in a significant but relatively modest decrease in BMI between baseline and the 12-month follow-up (-0.633 kg m^-2 , P_adj  = 0.048). Significant decreases were also observed for total cholesterol at 4 and 12 months, the total cholesterol to high-density lipoprotein cholesterol ratio at 4 months, 5-year CVD risk at 4 months, and fast food consumption at 12 months.

CONCLUSIONS

Our findings show that a family-centered brief intervention targeting physical activity and nutrition can generate slightly better obesity-related health outcomes than usual care alone.

Alcohol attitudes, motives, norms, and personality traits longitudinally classify nondrinkers, moderate drinkers, and binge drinkers using discriminant function analysis

INTRODUCTION

Binge drinking is commonly defined in the literature as consuming at least 5 drinks for males and 4 drinks for females. These quantities correspond to approximately a blood alcohol concentration of 0.08%, the level of intoxication making it illegal to drive in the United States.

METHODS

The study scrutinized the longitudinal classification of three drinker types using male (n=155) and female (n=351) college students. Measures of personality (sensation seeking, extraversion, agreeableness, conscientiousness, neuroticism, and openness), alcohol attitudes, alcohol motivations (social, coping, enhancement, and conformity), and alcohol social norms (typical students, friends, closest friends, and parents) were administered at Time 1. Drinker type (nondrinkers, moderate drinkers, or binge drinkers) was assessed one month later.

RESULTS

Discriminant function analyses revealed that the set of measures statistically distinguished among the three drinker types. The first function was significant and yielded high loadings for attitudes, social motives, enhancement motives, coping motives, closest friend norms, and friend norms for both genders. Model classification accuracy was 73% for the male and 67% female samples. Multivariate analysis of variance (MANOVA) compared mean differences in a 2 (gender: males or females)×3 (drinker type: nondrinkers, moderate drinkers, or binge drinkers) design. Measures systematically differing across all pairwise comparisons of the three drinker types, starting from the strongest effect (eta-squared), were as follows: alcohol attitudes, social motives, enhancement motives, closest friend norms, friend norms, coping motives, sensation seeking, and extraversion.

CONCLUSIONS

Attitude, motivation, and norm variables tended to be more important than personality in distinguishing drinker types. Considering the malleability of attitudes and belief motivations, the risk variables of alcohol attitudes, social motives, and enhancement motives identified in this research warrant consideration in prevention and campaign efforts targeting problematic drinking.

Prevention of Fetal Alcohol Spectrum Disorder: Current Canadian Efforts and Analysis of Gaps

Effective prevention of risky alcohol use in pregnancy involves much more than providing information about the risk of potential birth defects and developmental disabilities in children. To categorize the breadth of possible initiatives, Canadian experts have identified a four-part framework for fetal alcohol spectrum disorder (FASD) prevention: Level 1, public awareness and broad health promotion; Level 2, conversations about alcohol with women of childbearing age and their partners; Level 3, specialized support for pregnant women; and Level 4, postpartum support for new mothers. In order to describe the level of services across Canada, 50 Canadian service providers, civil servants, and researchers working in the area of FASD prevention were involved in an online Delphi survey process to create a snapshot of current FASD prevention efforts, identify gaps, and provide ideas on how to close these gaps to improve FASD prevention. Promising Canadian practices and key areas for future action are described. Overall, Canadian FASD prevention programming reflects evidence-based practices; however, there are many opportunities to improve scope and availability of these initiatives.

Alcohol interventions for mandated college students: A meta-analytic review

OBJECTIVE

When college students violate campus alcohol policies, they typically receive disciplinary sanctions that include alcohol education or counseling. This meta-analysis evaluated the efficacy of these "mandated interventions" to prevent future alcohol misuse.

METHOD

Studies were included if they evaluated an individual- or group-level intervention, sampled students mandated to an alcohol program, used a pretest-posttest design, and assessed alcohol use as an outcome. Thirty-one studies with 68 separate interventions (N = 8,621 participants; 35% women; 85% White) were coded by independent raters with respect to sample, design, methodological features, and intervention content; the raters also calculated weighted mean effect sizes, using random-effects models. A priori predictors were examined to explain variability in effect sizes.

RESULTS

In the 5 studies that used assessment-only control groups, mandated students reported significantly less drinking relative to controls (between-groups contrasts), d+ ranged from 0.13-0.20 for quantity and intoxication outcomes. In the 31 studies that provided within-group contrasts, significant effects were observed for all outcomes in the short-term (i.e., ≤ 3 months postintervention), with d+ ranging from 0.14-0.27; however, fewer significant effects appeared at longer follow-ups. Four commercially available intervention protocols (i.e., BASICS, e-CHUG, Alcohol 101, and Alcohol Skills Training Program) were associated with risk reduction.

CONCLUSIONS

Providing mandated interventions to students who violate campus alcohol policies is an effective short-term risk reduction strategy. Continued research is needed to maintain initial gains, identify the most useful intervention components, and determine the cost-effectiveness of delivery modes. (PsycINFO Database Record

Drinking Like an Adult? Trajectories of Alcohol Use Patterns Before and After College Graduation

BACKGROUND

College students who engage in high-risk drinking patterns are thought to "mature out" of these patterns as they transition to adult roles. College graduation is an important milestone demarcating this transition. We examine longitudinal changes in quantity and frequency of alcohol consumption between the college years and the 4 years after graduation and explore variation in these changes by gender and race/ethnicity.

METHODS

Participants were 1,128 college graduates enrolled in a longitudinal prospective study of health-risk behaviors. Standard measures of alcohol consumption were gathered during 8 annual personal interviews (76 to 91% annual follow-up). Graduation dates were culled from administrative data and self-report. Spline models, in which separate trajectories were modeled before and after the "knot" of college graduation, were fit to 8 annual observations of past-year alcohol use frequency and quantity (typical number of drinks/drinking day).

RESULTS

Frequency increased linearly pregraduation, slightly decreased postgraduation, and then rebounded to pregraduation levels. Pregraduation frequency increased more steeply among individuals who drank more heavily at college entry. Quantity decreased linearly during college, followed by quadratic decreases after graduation.

CONCLUSIONS

Results suggest that the postcollege "maturing-out" phenomenon might be attributable to decreases in alcohol quantity but not frequency. High-frequency drinking patterns that develop during college appear to persist several years postgraduation.

The impact of defensiveness and incident reactions on post-sanction drinking behaviors among mandated students

INTRODUCTION

Prior studies with mandated students (students referred for an intervention following violation of a campus alcohol policy) have suggested that decreases in drinking behaviors may occur before clinical intervention. Others studies have suggested that greater reductions were associated with lower defensiveness and stronger incident reactions, such as responsibility and aversiveness. The current study sought to integrate these findings and examine the influence of pre-sanction drinking and perceptions on mandated students' post-sanction drinking levels prior to attending a brief intervention.

METHODS

Data were collected as part of a longitudinal study of brief interventions in a mandated student sample (N=61, 43% female, 97% White). Participants completed demographic measures, scales measuring incident reactions and defensiveness, and a Time Line Follow Back assessing drinking quantity and frequency both pre- and post-sanction.

RESULTS

Analyses revealed significant post-sanction decreases in quantity (average total drinks per month) and frequency (number of monthly drinking days). Pre-sanction drinking quantity and frequency significantly predicted post-sanction quantity and frequency, respectively. Interaction effects suggest higher post-sanction quantities among moderate and heavier drinkers with higher defensiveness and lower aversiveness perceptions, while perceptions did not influence outcomes among light drinkers. None of the interactions involving blame or responsibility, or predicting post-sanction frequency, were significant.

CONCLUSIONS

These findings suggest a complex relationship between pre-sanction drinking and student reactions. Implications for mandated student interactions and future research directions are discussed.

Development and Implementation of CHOICES Group to Reduce Drinking, Improve Contraception, and Prevent Alcohol-Exposed Pregnancies in American Indian Women

Public health officials assert that prevention of alcohol-exposed pregnancies (AEP) should begin before conception, by reducing alcohol consumption in women at-risk for or planning pregnancy, and/or preventing pregnancy in women who are drinking at risky levels. One such effort is the Oglala Sioux Tribe (OST) CHOICES Program. While the OST CHOICES Program has been successfully implemented, a community-based needs assessment determined that the OST CHOICES intervention should expand and be delivered in a group setting using group motivational interviewing (MI) techniques. After extensive group MI and CHOICES group trainings, recruitment for CHOICES Group began and within a ten month period, a total of twelve groups with non-pregnant American Indian women were held for this pilot intervention. Evaluations completed by participants indicated that CHOICES Group sessions positively engaged members, had low levels of anger or tension, and had average levels of avoidance of personal responsibility. An evaluation of the CHOICES Group leaders indicated strengths in certain MI skills, although improvement is needed in some core MI and group leadership skills. This is an important expansion of a successful AEP prevention program (CHOICES), as well as a novel application of MI, and recommendations and future plans for this intervention are outlined.

The comparative effectiveness of individual and group brief motivational interventions for mandated college students

Individual brief motivational intervention (iBMI) is an efficacious strategy to reduce heavy drinking by students who are mandated to receive an alcohol intervention following an alcohol-related event. However, despite the strong empirical support for iBMI, it is unknown if the results from rigorously controlled research on iBMI translate to real-world settings. Furthermore, many colleges lack the resources to provide iBMI to mandated students. Therefore, group-delivered BMI (gBMI) might be a cost-effective alternative that can be delivered to a large number of individuals. The purpose of this study was to conduct a comparative effectiveness evaluation of iBMI and gBMI as delivered by staff at a university health services center. Participants (N = 278) were college students who were mandated to receive an alcohol intervention following an alcohol-related incident. Participants were randomized to receive an individual (iBMI; n = 133) or a Group BMI (gBMI; n = 145). Results indicated that both iBMI and gBMI participants reduced their peak estimated blood alcohol concentration (BAC) and the number of negative alcohol-related consequences at 1-, 3-, and 6-months postintervention. The iBMI and gBMI conditions were not significantly different at follow-up. These findings provide preliminary support for the use of iBMI and gBMIs for college students in real-world settings.

Decisional Balance: Alcohol Decisional Balance Intervention for Heavy Drinking Undergraduates

BACKGROUND

This study evaluated a decisional balance intervention among heavy drinking undergraduates and compared a nonweighted decisional balance proportion (DBP; Collins, Carey, & Otto, 2009) to a participant-weighted DBP with weights based on relative importance of items. We expected: (1) the intervention to decrease drinking compared to control; (2) the weighted intervention to be more effective compared to the nonweighted or control in reducing drinking; and (3) intervention efficacy to be moderated by initial DBP.

METHOD

Participants (N = 162, Mean age = 24.37, SD = 6.81, 27% male) were randomly assigned to an alcohol intervention wherein they were either asked to assign weights of importance to pros and cons (weighted intervention), or not (nonweighted intervention), or to control. Participants completed web-based questionnaires at baseline and again during a one month follow-up assessment.

RESULTS

Consistent with expectations, the nonweighted intervention was associated with reduced follow-up weekly drinking, and the weighted intervention was associated with reductions in drinking frequency. Results further indicated that initial decisional balance did not moderate intervention efficacy.

DISCUSSION

Findings suggest that the decisional balance procedure can reduce drinking but there was not compelling evidence for the addition of weights. This study lays the groundwork for enhancing future interventions by increasing empirical knowledge of the role motivation plays in heavy alcohol use.

Project INTEGRATE: An integrative study of brief alcohol interventions for college students

This article provides an overview of a study that synthesizes multiple, independently collected alcohol intervention studies for college students into a single, multisite longitudinal data set. This research embraced innovative analytic strategies (i.e., integrative data analysis or meta-analysis using individual participant-level data), with the overall goal of answering research questions that are difficult to address in individual studies such as moderation analysis, while providing a built-in replication for the reported efficacy of brief motivational interventions for college students. Data were pooled across 24 intervention studies, of which 21 included a comparison or control condition and all included one or more treatment conditions. This yielded a sample of 12,630 participants (42% men; 58% first-year or incoming students). The majority of the sample identified as White (74%), with 12% Asian, 7% Hispanic, 2% Black, and 5% other/mixed ethnic groups. Participants were assessed 2 or more times from baseline up to 12 months, with varying assessment schedules across studies. This article describes how we combined individual participant-level data from multiple studies, and discusses the steps taken to develop commensurate measures across studies via harmonization and newly developed Markov chain Monte Carlo (MCMC) algorithms for 2-parameter logistic item response theory models and a generalized partial credit model. This innovative approach has intriguing promises, but significant barriers exist. To lower the barriers, there is a need to increase overlap in measures and timing of follow-up assessments across studies, better define treatment and control groups, and improve transparency and documentation in future single intervention studies.

Change talk and relatedness in group motivational interviewing: a pilot study

BACKGROUND

Change talk (CT), or client speech in favor of change, is a hypothesized mechanism of action in motivational interviewing (MI) for substance use disorders. Although group-based treatment is the primary treatment modality for the majority of clients seeking substance use treatment, limited research has examined group motivational interviewing (GMI) among this population, and no study has examined CT within GMI. Therefore, in the current study we examined both standard CT (e.g., desire, ability, reason, need) and a novel phenomenon involving CT which we termed 'relatedness,' or the synergistic exchange of CT between and among group members.

METHOD

Data were utilized from an ongoing randomized controlled trial (RCT) examining the effectiveness of GMI relative to a treatment control condition (TCC) among U.S. veteran outpatients with a primary alcohol use disorder at a Veterans Affairs hospital. A subsample of participants (n = 52) from the RCT were randomly assigned to receive GMI or TCC. The majority of participants in the subsample had co-existing psychiatric (88%) and dual diagnosis drug use disorders (38%). Two of four treatment sessions were coded by trained raters for CT and relatedness.

RESULTS

Analyses demonstrated that CT and relatedness occurred with greater frequency in GMI compared to TCC, with effect sizes in the large range for each difference. Results held after controlling for number of group members in treatment sessions.

CONCLUSIONS

Findings suggest that GMI is associated with more frequent CT and relatedness than TCC, consistent with the broader literature demonstrating the influence of MI on CT.

Motivational Interviewing Interventions and Alcohol Abuse among College Students: A Systematic Review

Objective.

The study sought to assess the effectiveness of Motivational Interviewing (MI) interventions in reducing alcohol consumption among college students, as compared to no intervention or alternative interventions. It also sought to identify the potential moderators to MI intervention effects.

Data Source.

Database sources consulted included Cochrane Central Register of Control Trials, PsycINFO, PsycARTICLE, PsycLIT, CINAHL, and MEDLINE.

Study Inclusion and Exclusion Criteria.

Included studies were (1) underpinned by experimental, quasi-experimental, and nonexperimental designs; (2) studies in which participants were either college males only or females only or both; and (3) studies in which adaptations of MI were based on key MI principles. Excluded studies were (1) non-English language studies; (2) studies not published from 2000–2012; (3) studies in which participants were not college students; (4) studies in which intervention was not delivered by face-to-face approach; and (5) studies that failed to embark on postintervention follow-ups.

Data Extraction.

A total of 115 abstracts were screened. These were narrowed down to 13 studies from which data for the study were extracted.

Data Synthesis.

Selected studies were underpinned by experimental, quasi-experimental, and nonexperimental designs. Owing to the heterogeneity in selected studies, a narrative synthesis was used.

Results.

MI interventions were found to be effective in reducing alcohol consumption among college students, when compared to alternative interventions or no intervention. Potential moderators of MI intervention effects were identified to include practitioner's adherence to MI techniques and individual's drinking motives.

Conclusion.

MI presents itself as a promising tool that can augment the many existing social-environmental strategies of health promotion.

Exploring promising gender-sensitive tobacco and alcohol use interventions: results of a scoping review

This review examined the breadth of gender-sensitive tobacco and alcohol interventions that target girls and women. A comprehensive review of databases and websites was conducted in 2011/2012 for interventions that focused on girls and women health, incorporated an understanding of sex and/or gender, engaged with the determinants of women's health, and sought to reduce gender-related social and health inequities. Results of the review suggest that interventions designed with an understanding of the effect of gender roles, norms, and behaviors on women's health are limited and that much work remains to encourage practitioners to use a gender-sensitive approach when designing interventions.

When less is more and more is less in brief motivational interventions: characteristics of intervention content and their associations with drinking outcomes

Brief motivational interventions (BMIs) that aim to reduce alcohol use and related problems have been widely implemented in college settings. BMIs share common principles, but vary in specific content. Thus far, the variation in content has not been thoroughly understood in relation to intervention outcomes. The present study addressed this gap by examining variation in breadth of BMI content (i.e., total number of components covered), the extent to which content was personalized to participants, and the interaction between breadth and personalization in relation to treatment outcomes. Data (N = 6,047 participants across 31 separate BMI conditions) came from an integrative data analysis (IDA) study featuring individual-level data from a broad sample of 24 BMI studies of college students. Participants were assessed at baseline and at least 1 follow-up point, conducted up to 12 months postbaseline. Structural equation modeling revealed a significant interaction effect between breadth and personalization of BMI content on alcohol use and related problems at the long-term follow-up (6-12 months) but not at the short-term follow-up (1-3 months). Results indicated that "more is better" for reducing both alcohol use and related problems when BMIs were highly personalized to participants. For less personalized BMIs, coverage of more components was associated with increases in both alcohol use and problems. Findings point to the importance of strategically designing BMIs to maximize their impact on drinking outcomes in college students.

A review of decisional balance research and directions for brief alcohol intervention among college students

This paper provides a review of decisional balance (DB) and proposes strategies for improving DB measurement with respect to alcohol interventions for college students. Although existing alcohol interventions for college drinking are widely available, many undergraduates do not perceive any need to change their drinking. Intervention strategies that encourage students to consciously consider reasons for changing problem behaviors and resolve ambivalence may provide unique benefit. The DB and alcohol literature suggest; 1) a relationship exists between DB and motivation to change (MTC); 2) the decisional balance proportion (DBP) represents a promising new way to conceptualize MTC; and 3) while the DBP is a step forward in DB measurement, it can be improved. Alternative strategies proposed for improving the DBP include; 1) a weighted DBP, which may increase predictive ability and provide a closer approximation of an individual's MTC compared to the original DBP; 2) a coded DBP, which may allow for identification of common reasons why college students choose to drink or not drink; and 3) personalized DBP feedback, which may increase intervention efficacy by further highlighting the discrepancy between behaviors and goals. These strategies can be applied separately or in conjunction, and represent a potentially promising new avenue for DB research.

Comparison of Student Self-Reported and Administrative Data Regarding Intercession into Alcohol Misuse among College Freshmen Dormitory Residents

Intercession into collegiate alcohol misuse by the Department of Resident Live (DRL) in freshmen dormitories at one large, Mid-Atlantic, diverse, public university was examined. Freshmen dormitory resident drinkers (n=357), 71% of whom reported alcohol misuse, were surveyed. Student self-report and DRL documentation, respectively, revealed that 6.4% and 7.8% (Kappa=.77) of drinkers were documented with an alcohol violation, 4.2% and 3.4% (Kappa=.81) lost housing priority points, 1.4% and .6% (Kappa=.28) were referred for alcohol counseling, and 1.4% and .3% (Kappa = .33) were taken to the emergency room. DRL infrequently interceded into alcohol misuse, perhaps because most misuse occurred off-campus.

Addressing alcohol use and problems in mandated college students: a randomized clinical trial using stepped care

OBJECTIVE

Over the past 2 decades, colleges and universities have seen a large increase in the number of students referred to the administration for alcohol policies violations. However, a substantial portion of mandated students may not require extensive treatment. Stepped care may maximize treatment efficiency and greatly reduce the demands on campus alcohol programs.

METHOD

Participants in the study (N = 598) were college students mandated to attend an alcohol program following a campus-based alcohol citation. All participants received Step 1: a 15-min brief advice session that included the provision of a booklet containing advice to reduce drinking. Participants were assessed 6 weeks after receiving the brief advice, and those who continued to exhibit risky alcohol use (n = 405) were randomized to Step 2, a 60- to 90-min brief motivational intervention (n = 211), or an assessment-only control (n = 194). Follow-up assessments were conducted 3, 6, and 9 months after Step 2.

RESULTS

Results indicated that the participants who received a brief motivational intervention showed a significantly reduced number of alcohol-related problems compared to those who received assessment only, despite no significant group differences in alcohol use. In addition, low-risk drinkers (n = 102; who reported low alcohol use and related harms at 6-week follow-up and were not randomized to stepped care) showed a stable alcohol use pattern throughout the follow-up period, indicating they required no additional intervention.

CONCLUSION

Stepped care is an efficient and cost-effective method to reduce harms associated with alcohol use by mandated students.

Effects of choice on intervention outcomes for college students sanctioned for campus alcohol policy violations

This study tested the hypothesis that client choice influences intervention outcomes. We recruited 288 student drinkers (60% men, 67% freshmen) required to participate in an intervention due to a violation of campus alcohol policy. Participants were randomized either to self-chosen or researcher-assigned interventions. In the choice condition they selected either a brief motivational intervention (BMI) or a computer-delivered educational program. In the assigned condition they received 1 of the 2 interventions, assigned randomly. Follow-up assessments at 1 and 2 months revealed that choice was associated with higher intervention satisfaction. However, the assigned and choice conditions did not differentially change on consumption or consequences across intervention type. Overall, change scores favored the BMI over the computer-delivered intervention on consumption and consequences. Exploratory analyses revealed that given the choice of intervention, heavier-drinking students self-selected into the face-to-face BMI. Furthermore, among the students who received a BMI, the students who chose it (despite their heavier drinking) reduced drinks per drinking day more than did the assigned students. In summary, offering a choice of intervention to students mandated for campus alcohol violations increased the chance that at-risk students will select a more intensive and effective intervention.

How drunk am I? Misperceiving one's level of intoxication in the college drinking environment

One effective event-level index that can assist in identifying risky intoxication levels among college students is blood alcohol concentration (BAC). Despite widespread exposure to BAC information, doubt exists as to whether American college students can accurately estimate their own BAC level or drinking behaviors while intoxicated. This study assessed whether students can accurately guesstimate their BAC level and drinking behaviors used to estimate BAC (eBAC) while drinking in social college settings. Participants (N = 225; 56.4% male) consisted of emerging adults attending either a 2- or 4-year college who had at least one alcoholic drink within the 2 hr before assessment. Participants were approached at night when returning from parties and/or alcohol-serving establishments. They completed an initial questionnaire, gave a breath sample to assess breath alcohol content, and then completed an online follow-up questionnaire within 48 hr of baseline assessment. Participants at lower levels of intoxication tended to slightly overestimate their BAC level, while those at higher levels tended to markedly underestimate their BAC level. In addition, discrepancies among breath alcohol content, guesstimated BAC, and eBAC were found as a function of gender. Lastly, differences in eBAC scores did not differ when drinking behaviors were obtained via in vivo versus retrospective methodology. Findings suggest that college students generally have difficulty assessing their BAC level and drinking behaviors while drinking in the college social setting. This study offers particular insight for research relying on estimates of BAC as well as interventions utilizing BAC education.

Effectiveness of intervention on improvement of drug use among methadone maintained adults

The purpose of this study is to evaluate the effectiveness of three interventions (individual motivational interviewing, group motivational interviewing, or nurse-led hepatitis health promotion) in reducing drug use. A randomized, controlled trial was conducted with 256 methadone maintained moderate-to-heavy alcohol-using adults attending one of five MM outpatient clinics. Drug use in the overall sample was significantly reduced from baseline to 6-month follow-up, as assessed by a 30-day recall (p < 0.0001), with a trend apparent for 6-month recall (p = 0.09). The group and individual programs revealed significant decreases in drug use at the 30-day recall.

Reducing Alcohol Risk in Adjudicated Male College Students: Further Validation of a Group Motivational Enhancement Intervention

This study examined the effectiveness of a single-session group motivational enhancement alcohol intervention on adjudicated male college students. Over two sequential academic years, 230 students sanctioned by the university for alcohol-related infractions attended a 60- to 75-minute group intervention. The intervention consisted of a timeline followback, social norms education, decisional balance for behavioral change, blood alcohol content (BAC) information, expectancy challenge, and generation of behavioral goals. Participants were followed weekly for three months and showed reductions in drinking (29%) and alcohol-related consequences (32%) at three-month follow-up. The intervention was successful in reducing drinking for both first-year students and upperclassmen, with reductions appearing to be a function of the intervention and not the citation itself. Furthermore, a post hoc control condition revealed that those participants randomly assigned to the intervention group condition reduced drinking (19%) and alcohol-related consequences (44%) more than participants in the control condition over one month. These results provide continued evidence of the effectiveness of group motivational enhancement interventions with adjudicated male college students.

Predictors of hepatitis knowledge improvement among methadone maintained clients enrolled in a hepatitis intervention program

This randomized, controlled study (n = 256) was conducted to compare three interventions designed to promote hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination completion, among clients undergoing methadone maintenance treatment (MMT) in Los Angeles and Santa Monica. The participants were randomized into three groups: Motivational Interviewing-Single Session (MI-Single), Motivational Interviewing-Group (MI-Group), or Nurse-Led Hepatitis Health Promotion (HHP). All three treatment groups received the 3-series HAV/HBV vaccine. The MI sessions were provided by trained therapists, the Nurse-Led HHP sessions were delivered by a research nurse. The main outcome variable of interest was improvement in HBV and HCV knowledge, measured by a 6-item HBV and a 7-item HCV knowledge and attitude tool that was administered at baseline and at 6-month follow-up. The study results showed that there was a significant increase in HBV- and HCV-related knowledge across all three groups (p < 0.0001). There were no significant differences found with respect to knowledge acquisition among the groups. Irrespective of treatment group, gender (P = 0.008), study site (P < 0.0001) and whether a participant was abused as a child (P = 0.017) were all found to be predictors of HCV knowledge improvement; only recruitment site (P < 0.0001) was found to be a predictor of HBV knowledge. The authors concluded that, although MI-Single, MI-Group and Nurse-Led HHP are all effective in promoting HBV and HCV knowledge acquisition among MMT clients, Nurse-Led HHP may be the method of choice for this population as it may be easier to integrate and with additional investigation may prove to be more cost efficient.

Exploring the role of positive and negative consequences in understanding perceptions and evaluations of individual drinking events

While research has established that drinking more alcohol is associated with experiencing more positive and negative alcohol-related consequences, less is known about how college students evaluate their drinking experiences. Evaluations of drinking events may vary with factors such as how much one drinks, which consequences one experiences, and the context (i.e., where and with whom) one drinks on a given occasion. This research used daily data (Level 2: N=166 students, 61% female; Level 1: N=848 person drinking days) to explore the relationship between quantity of alcohol consumed and experience of specific domains of positive and negative consequences and to examine how the experience of specific consequences related to overall evaluation of the drinking experience. Drinking on a given day was positively associated with experiencing more negative (social and personal) and more positive (image, fun/social, and relaxation) consequences. With respect to the formation of overall impressions, negative (social and personal) consequences were associated with less favorable evaluations whereas positive (image, fun/social, and relaxation) consequences were associated with more favorable evaluations of the drinking experience. Indirect effects analyses suggested that consequences (negative personal, negative social, positive fun/social, and positive relaxation) significantly mediated the relationship between drinking and overall evaluation at the daily level. These results underscore the importance of considering both positive and negative consequences in understanding students' choices to drink and how they evaluate their experiences.

Predictors of HAV/HBV vaccination completion among methadone maintenance clients

This randomized, controlled study (N = 256) was conducted to compare three interventions designed to promote hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination completion among clients undergoing methadone maintenance (MM) treatment. Participants were recruited from five MM treatment sites in Southern California and randomized into three groups: Motivational Interviewing-Single (MI-Single), Motivational Interviewing-Group (MI-Group); and Nurse-Led Hepatitis Health Promotion (HHP). All were offered the three-series HAV/HBV vaccine. A total of 148 participants completed the vaccine. Groups did not differ in rate of vaccination completion (73.6%, HHP group, vs. 65% and 69% for the MI-Single and MI-Group, respectively). The equivalence of findings across groups suggests the value of including nurses with a comprehensive health focus in promoting vaccination completion.

A peer-drinking group motivational intervention among Thai male undergraduate students

BACKGROUND

Excessive alcohol consumption, particularly among young males, is an important global health problem, in part because of the increased risks of intentional and non-intentional injuries, uses of illicit drug, crime, and psychiatric disorders. There are no data available to evaluate the extent to which interventions are effective in reducing hazardous/harmful alcohol consumption among young males in Thailand. We examined the efficacy of alcohol harm reduction strategies administered as a peer-drinking group motivational intervention (PD-GMI) among Thai male undergraduates.

METHODS

We used a quasi-experimental study design that included two student groups assessed at baseline and at two time points post-intervention. Participants were students enrolled in two public universities and who reported alcohol consumption during the current academic year. Students in one university were assigned to an assessment-only study group (n=110); and students in the other university were assigned to a 2-h PD-GMI (n=115). This intervention was designed to (1) increase the awareness of risks associated with hazardous/harmful alcohol consumption; (2) enhance students' motivation to change their drinking behaviours; and (3) encourage harm reduction strategies during episodes of alcohol consumption. Alcohol consumption and adverse consequences were assessed using the Alcohol Use Disorders Identification Test (AUDIT) and the Rutgers Alcohol Problem Index (RAPI).

RESULTS

Students receiving the intervention had significant reductions in mean AUDIT scores; 50.4% at baseline to 1-month and 61.2% at baseline to 3-month post-intervention. Their mean RAPI scores were also reduced; 42.0% at baseline to 1-month and 42.9% at baseline to 3-month post-intervention. Reductions in alcohol consumption and the prevalence of harmful alcohol consumption patterns were statistically significant among students in the intervention group versus those in the control group. The reductions remained after adjustments for baseline differences.

CONCLUSIONS

These results suggest the efficacy of the PD-GMI intervention for reducing alcohol consumption and adverse consequences among Thai male students.

What makes group MET work? A randomized controlled trial of college student drinkers in mandated alcohol diversion

Nationally, college drinkers exhibit the highest rates of alcohol consumption and represent the largest percentage of problem drinkers. Group motivational enhancement therapy (GMET) has been found to catalyze problem drinking reductions among college student samples. Although research supporting the use of single-session GMET in college samples (general and mandated) is emergent, no studies have evaluated a comprehensive model of the potential active ingredients of this group intervention. College students (N = 206; 88% White; 63% men; M age = 18.6) mandated to a university alcohol diversion program were randomly assigned to 1 of 3 conditions: the standard-of-care 2-session "Focus on Alcohol Concerns" education group (FAC), a single GMET, or a single alcohol information-only control group (AI) to evaluate the role of 5 putative mediators: readiness to change, self-efficacy, perceived risk, norm estimates, and positive drinking expectancies. At 3- and 6-month follow-ups, GMET students demonstrated greater reductions in problem drinking outcomes (drinks per drinking day, hazardous drinking symptoms, and alcohol-related problems). Of the 5 mediators proposed, only self-efficacy emerged as a significant mediator.

Hostility in mandated students: exploratory analysis and implications for treatment

College students mandated to receive an intervention following an alcohol-related campus violation are a high-risk group of students experiencing the negative effects of alcohol. Understanding the psychological properties associated with mandated students' alcohol use may provide useful clinical information. Hostility is a trait that has shown association with heavy drinking in adults but has gone unstudied in mandated students. We examined the relationship between hostility and a variety of drinking-related variables in mandated students (N = 466). Results indicated that individuals reporting higher levels of hostility reported riskier drinking and alcohol-related problems, yet exhibited ambivalence regarding their alcohol use. Findings are discussed in the context of treating mandated students exhibiting high hostility and risky drinking, a particularly challenging population.

Effect of motivational interviewing on reduction of alcohol use

BACKGROUND

Methadone-maintained (MM) clients who engage in excessive alcohol use are at high risk for HIV and hepatitis B virus (HBV) infection. Nurse-led hepatitis health promotion (HHP) may be one strategy to decrease alcohol use in this population.

OBJECTIVE

To evaluate the impact of nurse-led HHP, delivered by nurses compared to motivational interviewing (MI), delivered by trained therapists in group sessions or one-on-one on reduction of alcohol use.

METHODS

A three-arm randomized, controlled trial, conducted with 256 MM adults attending one of five MM outpatient clinics in the Los Angeles area. Within each site, moderate-to-heavy alcohol-using MM participants were randomized into one of three conditions: (1) nurse-led hepatitis health promotion group sessions (n=87); (2) MI delivered in group sessions (MI-group; n=79), or (3) MI delivered one-on-one sessions (MI-single, n=90).

RESULTS

Self-reported alcohol use was reduced from a median of 90 drinks/month at baseline to 60 drinks/month at 6-month follow-up. A Wilcoxon sign-rank test indicated a significant reduction in alcohol use in the total sample (p<.05). In multiple logistic regression analysis controlling for alcohol consumption at baseline and other covariates, no differences by condition were found.

DISCUSSION

As compared to two programs delivered by MI specialists, a culturally-sensitive and easy to implement nurse-led HHP program produced similar reductions in alcohol use over 6 months. Employing nurse-led programs may allow cost savings for treatment programs as well as a greater integration of alcohol reduction counseling along with a more comprehensive focus on general health-related issues than previously conducted.

Family history of alcohol abuse moderates effectiveness of a group motivational enhancement intervention in college women

This study examined whether a self-reported family history of alcohol abuse (FH+) moderated the effects of a female-specific group motivational enhancement intervention with first-year college women. First-year college women (N=287) completed an initial questionnaire and attended an intervention (n=161) or control (n=126) group session, of which 118 reported FH+. Repeated measures ANCOVA models were estimated to investigate whether the effectiveness of the intervention varied as a function of one's reported family history of alcohol abuse. Results revealed that family history of alcohol abuse moderated intervention efficacy. Although the intervention was effective in producing less risky drinking relative to controls, among those participants who received the intervention, FH+ women drank less across five weeks of follow-up than FH- women. The current findings provide preliminary support for the differential effectiveness of motivational enhancement interventions with FH+ women.

Binge drinking in college-aged women: framing a gender-specific prevention strategy

PURPOSE

To provide an overview of binge drinking in college-aged women and to suggest strategies for nurse practitioners (NPs) to assist women in preventing the negative consequences associated with this behavior.

DATA SOURCES

Original research articles and comprehensive review articles identified through Medline, CINAHL, and OVID databases.

CONCLUSIONS

Researchers have shown that the rates of binge drinking in college-aged women are increasing, which places these women at increased risk for the long-term complications associated with alcohol use.

IMPLICATIONS FOR PRACTICE

NPs must be aware of this phenomenon and carefully screen women for high-risk alcohol use. Prevention strategies are reviewed and include the use of brief motivational interviews delivered during individual client encounters as well as through Web-based programs.

Impact of the "peers as family" dormitory wing-based intervention on college student alcohol use and its secondhand effects

An intervention to reduce college alcohol use and secondhand effects was tested. Freshmen dormitory wings at a large Mid-Atlantic public university were assigned to single-gender (SG) or mixed-gender (MG) Information-Motivation-Behavior (IMB) workshops implemented during the first weeks of school, or a control condition. Students were surveyed before school began and at 2- and 6-month follow-up. Analyses indicated that, among males, the adjusted mean weekly alcohol use was lower in the SG than the control condition (1.89 vs. 2.72, p = .041). Among females, the adjusted mean weekly alcohol use was lower in the MG than the SG (1.60 vs. 2.44, p = .021) and control condition (1.60 vs. 2.27, p = .056). Further research should identify underlying mechanisms for effective alcohol behavior change among male and female wing-mates.

Face-to-Face Interaction Compared with Video Watching on Use of Physical Activity in Peripheral Arterial Disease: A Pilot Trial

Few studies have defined the association of physician-patient communication with physical activity levels in patients with peripheral arterial disease. We hypothesized that a face-to-face intervention versus video watching would improve physical activity levels in patients with peripheral arterial disease. The authors conducted a randomized trial involving 2 interventions. The face-to-face intervention included a brief dialogue with patients to understand their perceptions of peripheral arterial disease and importance of walking. The comparison group watched a video that included an overview of peripheral arterial disease. The primary outcome was changed from baseline to follow-up in levels of physical activity. Fiftyone patients with peripheral arterial disease were randomized. There were no statistically significant differences between the 2 groups in reported activity level or walking ability at 12 weeks. For within group changes, the patients in the video-watching group improved their walking speed (8.5%; SD = 4.1; P = .05). Patients with peripheral arterial disease may benefit from the use of an educational video to increase the use of unsupervised physical activity. Further research is needed to identify interventions that can increase the use of unsupervised physical activity in this population.
