Predictors of Booster Engagement Following a Web-Based Brief Intervention for Alcohol Misuse Among National Guard Members: Secondary Analysis of a Randomized Controlled Trial.

ABSTRACT:

Background

Alcohol misuse is a major health concern among military members. Reserve component members face unique barriers as they live off base with limited access to behavioral health services. Web and app-based brief interventions are a promising means to improve access to treatment for those who misuse alcohol, with the use of booster sessions to enhance effectiveness, solidify gains, and reinforce changes. However, little is known about who will engage in booster sessions.

Objective

This study aims to evaluate booster engagement across booster delivery modalities (Web and Peer) and identify participant-specific factors associated with booster session engagement.

Methods

Following a brief web-based alcohol misuse intervention in National Guard members (N=739), we examined engagement in a series of three booster sessions. Using unadjusted and adjusted models, demographic and clinical characteristics that may serve as predictors of booster session engagement were examined across the 2 arms of the trial with different types of booster sessions: peer-delivered (N=245) and web-delivered (N=246).

Results

Booster session completion was greater for Peer than Web Booster sessions, with 142 (58%) service members in the Peer Booster arm completing all three boosters compared with only 108 (44%) of participants in the Web Booster arm (χ²₃=10.3; P=.006). In a model in which the 2 groups were combined, socioeconomic factors predicted booster engagement. In separate models, the demographic and clinical predictors of booster engagement varied between the 2 delivery modalities.

Conclusions

The use of peer-delivered boosters, especially among subsets of reserve members at risk of lack of engagement, may foster greater uptake and improve treatment outcomes.

Project description:ObjectivesThe objective was to assess the relationship between alcohol use and misuse and patient sex among emergency department (ED) patients by comparing self-reported estimates of quantity and frequency of alcohol use, estimated blood alcohol concentrations (eBACs) when typically drinking and during heavy episodic drinking (binging), and alcohol misuse severity, to understand sex differences in alcohol use and misuse for this population.MethodsThe authors surveyed a random sample of nonintoxicated, subcritically ill or injured, 18- to 64-year-old English- or Spanish-speaking patients on randomly selected dates and times at two EDs during July 2009 and August 2009. Participants self-administered a questionnaire about their self-reported alcohol use during a typical month within the past 12 months and the Alcohol Use Disorders Identification Test (AUDIT). Using the formulae by Matthews and Miller, sex-specific eBACs were calculated for participants according to their reported weight and the number of reported alcoholic drinks consumed on days when typically drinking and on days of heavy episodic (binge) drinking (five or more drinks/occasion for men, four or more drinks for women). Sex-specific alcohol misuse severity levels (low-risk, harmful, hazardous, and dependence) were calculated using AUDIT scores. Wilcoxon rank-sum and Pearson's chi-square tests were used to compare outcomes by sex. Negative binomial regression was used to assess the relationship between sex and the number of drinks consumed on a typical day, the number of days spent drinking and binging, and estimated AUDIT scores. Logistic regression was used to assess the outcome of the presence of binging according to sex. Multinomial logistic regression was used to compare by sex the percentage of days spent drinking and binging in 1 month, eBACs when typically drinking and when binging, and AUDIT at-risk drinking levels. Incidence rate ratios (IRRs) and adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were estimated. All models were adjusted for patient demographic characteristics.ResultsOf the 513 participants, 52.1% were women, 55.8% were white non-Hispanic, and their median age was 34 years (interquartile range [IQR] = 25 to 46 years). Men reported greater mean alcohol consumption than women when typically drinking (4.3 vs. 3.3 drinks/day; p < 0.001) and during heavy episodic drinking (8.6 vs. 5.3 drinks/occasion; p < 0.001). Men spent more days drinking (IRR = 1.41, 95% CI = 1.19 to 1.65) and engaging in heavy episodic drinking (IRR = 1.68, 95% CI = 1.31 to 2.17) than women. Additionally, men were more likely to engage in heavy episodic drinking (AOR = 1.72, 95% CI = 1.16 to 2.56) than women. However, the mean eBACs for men and women were similar when typically drinking (0.05 vs. 0.06; p < 0.13) and during heavy episodic drinking (0.13 vs. 0.12; p < 0.13). Mean AUDIT scores were greater for men than women (7.5 vs. 5.3; p < 0.001), although alcohol misuse severity levels were similar between men and women (24.4% vs. 26.6% for hazardous, 2.8% vs. 2.2% for harmful, and 6.5% vs. 3.4% for dependence; p < 0.38).ConclusionsAlthough men drink more than women, women have similar eBACs with comparable levels of alcohol misuse. Women may benefit from recognizing that they are reaching similar levels of intoxication compared to men. Addressing these differences and possible health implications in future ED brief interventions may induce changes in problematic alcohol use among women.

Project description:Emergency department (ED) visits present an opportunity to deliver brief interventions to reduce violence and alcohol misuse among urban adolescents at risk of future injury.To determine the efficacy of brief interventions addressing violence and alcohol use among adolescents presenting to an urban ED.Between September 2006 and September 2009, 3338 patients aged 14 to 18 years presenting to a level I ED in Flint, Michigan, between 12 pm and 11 pm 7 days a week completed a computerized survey (43.5% male; 55.9% African American). Adolescents reporting past-year alcohol use and aggression were enrolled in a randomized controlled trial (SafERteens).All patients underwent a computerized baseline assessment and were randomized to a control group that received a brochure (n = 235) or a 35-minute brief intervention delivered by either a computer (n = 237) or therapist (n = 254) in the ED, with follow-up assessments at 3 and 6 months. Combining motivational interviewing with skills training, the brief intervention for violence and alcohol included review of goals, tailored feedback, decisional balance exercise, role plays, and referrals.Self-report measures included peer aggression and violence, violence consequences, alcohol use, binge drinking, and alcohol consequences.About 25% (n = 829) of screened patients had positive results for both alcohol and violence; 726 were randomized. Compared with controls, participants in the therapist intervention showed self-reported reductions in the occurrence of peer aggression (therapist, -34.3%; control, -16.4%; relative risk [RR], 0.74; 95% confidence interval [CI], 0.61-0.90), experience of peer violence (therapist, -10.4%; control, +4.7%; RR, 0.70; 95% CI, 0.52-0.95), and violence consequences (therapist, -30.4%; control, -13.0%; RR, 0.76; 95% CI, 0.64-0.90) at 3 months. At 6 months, participants in the therapist intervention showed self-reported reductions in alcohol consequences (therapist, -32.2%; control, -17.7%; odds ratio, 0.56; 95% CI, 0.34-0.91) compared with controls; participants in the computer intervention also showed self-reported reductions in alcohol consequences (computer, -29.1%; control, -17.7%; odds ratio, 0.57; 95% CI, 0.34-0.95).Among adolescents identified in the ED with self-reported alcohol use and aggression, a brief intervention resulted in a decrease in the prevalence of self-reported aggression and alcohol consequences.clinicaltrials.gov Identifier: NCT00251212.

Project description:BackgroundSexual violence (SV) incidence among college women has been invariant for the past 20 years. Innovative prevention strategies that are low resource and technology driven but demonstrate efficacy are greatly needed.ObjectiveThe aim of this study was to determine the efficacy of a novel theoretically driven internet-based intervention for first-year college students who identify as women (RealConsent) in reducing their risk of exposure to SV and alcohol misuse as well as increasing alcohol protective and bystander behaviors.MethodsThis randomized controlled trial involved first-year college students who identified as women (n=881) attending 1 of 3 universities in the southeastern United States. Participants aged 18 to 20 years were randomized to RealConsent (444/881, 50.4%) or to an attention-matched placebo control (437/881, 49.6%). RealConsent is fully automated and consists of four 45-minute modules that incorporate entertainment-education media and proven behavior change techniques. The primary outcome was exposure to SV; the secondary outcomes were alcohol protective behaviors, dating risk behaviors, alcohol misuse, and bystander behavior. Study outcomes were assessed at baseline and 6-month follow-up.ResultsAmong participants with some exposure to SV, those in the RealConsent group experienced less exposure to SV than the placebo group (adjusted incidence rate ratio 0.48, 95% CI 0.33-0.69; P=.002). Furthermore, participants in the RealConsent group engaged in more alcohol protective behaviors (adjusted odds ratio 1.17, 95% CI 0.12-2.22; P=.03) and were less likely to binge drink (adjusted incidence rate ratio 0.81, 95% CI 0.67-0.97; P=.003). Finally, participants in the RealConsent group who had 100% dosage were more likely to engage in bystander behavior than those with <100% dosage plus placebo group (adjusted odds ratio 1.72, 95% CI 1.17-2.55; P=.006).ConclusionsA comprehensive exposure to SV, alcohol use, and bystander educational program was successful in decreasing the occurrence of exposure to SV among those most at risk and in increasing alcohol protective behaviors. Because of its web-based and mobile technologies, RealConsent can be easily disseminated and holds potential for reducing campus SV.Trial registrationClinicalTrials.gov NCT03726437; https://clinicaltrials.gov/ct2/show/NCT03726437.
