Behavioral Economic and Wellness-based Approaches for Reducing Alcohol Use and Consequences Among Diverse Non-Student Emerging Adults: Study Protocol for Project BLUE, a Randomized Controlled Trial

Background

Emerging adults (EAs) who are not 4-year college students nor graduates are at elevated risk for lifetime alcohol use disorder, comorbid drug use, and mental health symptoms, compared to college graduates. There is a need for tailored brief alcohol intervention (BAI) approaches to reduce alcohol risk and to facilitate healthy development in this high-risk population. Most BAIs include a single session focused on discussing risks associated with drinking and correcting normative beliefs about drinking rates. EAs may benefit from additional elements that enhance general wellness. The Substance-Free Activity Session (SFAS) aims to clarify life goals and values and increase goal-directed activities that provide alternatives to alcohol use, and the Relaxation Training (RT) session teaches relaxation and stress reduction skills.

Methods

The present study is a randomized 3-group (BAI+SFAS vs. RT+SFAS vs. education control) trial with 525 EAs (175 per group; estimated 50% women & 50% African American) who report recent risky drinking and who are not students or graduates of 4-year colleges. Participants will have the option of completing the intervention sessions in person or via a secure video teleconference. Levels of drinking and alcohol-related problems will be evaluated at baseline and 1, 3, 6, and 12-months post-intervention. The primary hypothesis is that both BAI+SFAS and RT+SFAS participants will report significantly greater reductions in alcohol use and problems relative to education control participants, with no differences in outcomes between the two active treatment conditions.

Discussion

The results of this study will inform alcohol prevention efforts for high-risk community dwelling emerging adults.

Prevention of Alcohol-related Incidents in the U.S. Air Force: Results From a Cluster Randomized Trial

BACKGROUND

Alcohol misuse poses significant public health concerns in the U.S. Military. An Alcohol Misconduct Prevention Program (AMPP), which includes a brief alcohol intervention (BAI) session, plus random breathalyzer program, has been shown to reduce alcohol-related incidents (ARIs) among Airmen undergoing training.

PURPOSE

The current study sought to examine whether a booster BAI administered at the end of Airmen's training reduced ARIs out to a 1-year follow-up.

METHODS

Participants were 26,231 U.S. Air Force Technical Trainees recruited between March 2016 and July 2018. Participants were cluster randomized by cohort to two conditions: AMPP + BAI Booster or AMPP + Bystander Intervention. The primary analysis was a comparison of the interventions' efficacies in preventing Article 15 ARIs at a 1-year follow-up, conducted using a generalized estimating equations logistic regression model controlling for covariates.

RESULTS

There was no significant difference by condition in Article 15 ARIs at the 1-year follow-up (P = .912).

CONCLUSIONS

Findings suggest that a booster may not be necessary to produce maximum effects beyond the initial AMPP intervention. It is also possible that alcohol behaviors changed as a result of the intervention but were not captured by our outcome measures. Future research should consider alternative outcomes or participant-tracking measures to determine whether a different or more intensive BAI booster is effective. The majority of Article 15 ARIs were for underage drinking; therefore, developing an intervention focused on this problem behavior could lead to large reductions in training costs in the military.

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.

A randomized pilot program to reduce opioid use following dental surgery and increase safe medication return

Research indicates that increased cumulative exposure (duration of administration and strength of dose) is associated with long-term opioid use. Because dentists represent some of the highest opioid prescribing medical professionals in the US, dental practices offer a critical site for intervention. The current study used a randomized clinical trial design to examine the efficacy of an opioid misuse prevention program (OMPP), presented as a brief intervention immediately prior to dental extraction surgery. The OMPP provided educational counseling about risks and appropriate use of opioid medication, as well as 28 tablets of ibuprofen (200 mg) and 28 tablets of acetaminophen (500 mg) for weaning off opioid medication. This was compared with a Treatment as Usual (TAU) control condition. Participants were individuals presenting for surgery who were eligible for opioid medication (N = 76). Follow up assessment was conducted at 1 week following surgery, with 4 individuals refusing follow up or not prescribed opioid. Intent to treat analysis indicated a non-significant treatment group effect (N = 72, Beta = 0.16, p = .0835), such that the OMPP group self-reported less opioid use (in morphine milligram equivalents, MMEs) than the TAU group (37.94 vs. 47.79, effect size d = 0.42). Sensitivity analysis, excluding individuals with complications following surgery (n = 6) indicated a significant treatment group effect (N = 66, Beta = 0.24, p = .0259), such that the OMPP group self-reported significantly less MMEs than the TAU group (29.74 vs. 43.59, effect size d = 0.56). Results indicate that a 10-minute intervention and provision of non-narcotic pain medications may reduce the amount of self-administered opioid medication following dental surgery.

Access to environmental reward mediates the relation between posttraumatic stress symptoms and alcohol problems and craving

Symptoms of posttraumatic stress (PTS) show significant comorbidity with alcohol use, but little is known about the mechanisms that might account for this comorbidity. Deficits in reward functioning have long been implicated in alcohol misuse and more recently in PTS reactions, but no study has examined whether reward deprivation may serve as a transdiagnostic risk factor for comorbid PTS-alcohol misuse. The current cross-sectional study sought to test the behavioral economic hypothesis that reward deprivation would be related to both PTS symptoms and alcohol problems, and would mediate the relation between PTS symptoms and alcohol problems in college students. We recruited a diverse sample of urban college students (N = 203, Mage = 21.5 years, SD = 5.5; 79.5% female; 56.8% White, 28.1% Black, .9% Asian, 9.8% Multiracial) who endorsed both alcohol use and PTS symptoms. Reward deprivation (lack of access to, and ability to, experience reward) was related to alcohol problems, and a lack of access to reward was related to PTS symptoms. Furthermore, reward access mediated the relation between PTS symptoms and alcohol problems and craving, after controlling for alcohol use, age, gender, and race. These data provide preliminary support for behavioral economic models of alcohol comorbidity and suggest that treatments for combined PTS and alcohol misuse should attempt to reduce barriers to accessing natural rewards.

Impact of Combat and Social Support on PTSD and Alcohol Consumption in OEF/OIF Veterans

We tested buffering and direct effect theories of social support to determine if combat exposure level moderated relationships between two aspects of social support (unit cohesion and postdeployment support) and two outcomes (PTSD and alcohol consumption) in 69 hazardous-drinking OEF/OIF veterans (65% Caucasian, 91% male). Combat exposure moderated the relationship between unit cohesion and PTSD. Unit cohesion was related to lower PTSD severity only for veterans with less severe combat exposure. Higher postdeployment support was related to less severe PTSD for all veterans. Alcohol consumption results were not significant.

Effects of Disasters on Smoking and Relapse: An Exploratory Study of Hurricane Katrina Victims

BACKGROUND

Psychosocial stress maintains cigarette use and precipitates relapse, but little is known about how natural disasters in particular affect smoking.

PURPOSE

To determine the feasibility of recruiting victims soon after a natural disaster for a survey study, and to assess the types and determinants of changes in smoking behavior resulting from exposure to the disaster.

METHODS

A convenience sample of 35 Hurricane Katrina refugees who had smoked more than 100 cigarettes in their lifetime were surveyed one month after the storm to evaluate changes in smoking behavior.

RESULTS

Among a small sample of former smokers, more than half relapsed after Katrina, citing stress, urge, and sadness. Among current smokers, 52% increased their smoking after Katrina by more than half a pack per day on average. Most individuals who increased their smoking or relapsed expressed interest in receiving cessation assistance within the next month.

DISCUSSION

Stress-related increases in smoking and relapse may be common after a natural disaster.

TRANSLATION TO HEALTH EDUCATION PRACTICE

Health education professionals have an important role to play in responding to changes in tobacco use in the aftermath of disasters. Educational interventions to discourage tobacco use as a coping strategy may be especially warranted given the high level of interest expressed in smoking cessation.
