Testing the efficacy of motivational strategies, empathic reflections, and lifelike features in a computerized intervention for alcohol use: A factorial trial

A Causal Analysis of Young Adults' Binge Drinking Reduction and Cessation

BACKGROUND

This study, using the multiple disadvantage model (MDM), sought to identify factors (disadvantaging social disorganization, social structural, social integration, health/mental health, co-occurring substance use, and substance treatment access factors) in young adults' binge drinking reduction and cessation in the United States.

METHODS

We extracted data on 942 young adult binge drinkers (25-34 years, 47.8% female) from the National Longitudinal Study of Adolescent to Adult Health (Add Health), carrying out a temporal-ordered causal analysis, meaning the evaluation of select variables' impacts on an outcome at a subsequent time.

RESULTS

MDM found a relatively high reduction likelihood for non-Hispanic African Americans and respondents with relatively more education. MDM found a relatively low reduction likelihood accompanying an alcohol-related arrest, higher income, and greater number of close friends. Change to nondrinking was found more likely for non-Hispanic African Americans, other non-Hispanic participants having minority ethnicity, older respondents, those with more occupational skills, and healthier respondents. Such change became less likely with an alcohol-related arrest, higher income, relatively more education, greater number of close friends, close friends' disapproval of drinking, and co-occurring drug use.

CONCLUSIONS

Interventions incorporating a motivational-interviewing style can effectively promote health awareness, assessment of co-occurring disorders, friendships with nondrinkers, and attainment of occupational skills.

Findings From the Step Up, Test Up Study of an Electronic Screening and Brief Intervention for Alcohol Misuse in Adolescents and Young Adults Presenting for HIV Testing: Randomized Controlled Efficacy Trial

BACKGROUND

Substance use, particularly binge drinking of alcohol and noninjection substance use, is associated with increased risk for HIV infection among youth, but structured substance use screening and brief intervention are not often provided as part of HIV risk reduction.

OBJECTIVE

The purpose of the study was to test the efficacy of a fully automated electronic screening and brief intervention, called Step Up, Test Up, to reduce alcohol misuse among adolescents and young adults presenting for HIV testing. Secondary objectives were reduction in sexual risk and uptake of pre-exposure prophylaxis (PrEP) for HIV prevention.

METHODS

Youth aged 16 years to 25 years who presented for HIV testing at community-based locations were recruited for study participation. Those who screened at moderate to high risk on the Alcohol Use Disorders Identification Test were randomized (1:1) to either an electronic brief intervention or a time-attention control. The primary outcome was change in alcohol use at 1, 3, 6, and 12-month follow-ups. Negative binomial and log binomial regression analyses with generalized estimating equations were conducted to evaluate the intervention efficacy.

RESULTS

Among a sample of 329 youth, there were no significant differences in alcohol use outcomes between conditions over time or at the 1, 3, 6, or 12-month time points. In terms of secondary outcomes, there was evidence of reduction in condomless insertive anal sex under the influence of alcohol and drugs at 12 months compared with 3 months in the intervention versus the attention control condition (incidence rate ratio=0.15, 95% CI 0.05-0.44); however, there were no other significant differences in sexual risk and no difference in PrEP engagement.

CONCLUSIONS

We found no effect of electronic brief intervention to reduce alcohol use and some effect on sexual risk among youth aged 16 years to 25 years who present for HIV testing.

Intervenciones para reducir el consumo de alcohol en jóvenes universitarios

Introducción: el consumo nocivo y excesivo de alcohol en los jóvenes ha sido reconocido como un comportamiento de riesgo significativo, por tanto, reducir el consumo y los problemas asociados es una prioridad entre los investigadores, educadores y profesionales de la salud que trabajan con esta población. Objetivo: examinar la evidencia actual sobre las intervenciones para reducir el consumo de alcohol de jóvenes universitarios. Método: se utilizó la metodología propuesta por Toronto y Remington. Para la evaluación y selección de los artículos cuantitativos se empleó el Instrumento de Criterios de Elegibilidad para la Selección de los Artículos de Investigación (ICrESAI) y para la evaluación de los ensayos clínicos aleatorizados se empleó la lista de verificación Estándares Consolidados de Informes de Ensayos (Consort). Resultados: se encontraron trece artículos, diez de ellos ensayos clínicos aleatorizados, dos cuantitativos longitudinales y un ensayo factorial. Conclusión: se encontró una gran variedad de diseños y propuestas de intervención, dentro de las cuales se demostró que las intervenciones breves entregadas de manera digital, tanto en la web, como en teléfonos inteligentes, son efectivas para reducir el consumo de riesgo de alcohol entre los jóvenes.

Alcohol, Drinking Pattern, and Chronic Disease

This review discusses the inconsistent recommendations on alcohol consumption and its association with chronic disease, highlighting the need for an evidence-based consensus. Alcohol is an addictive substance consumed worldwide, especially in European countries. Recommendations on alcohol consumption are controversial. On one hand, many nonrandomized studies defend that moderate consumption has a beneficial cardiovascular effect or a lower risk of all-cause mortality. On the other hand, alcohol is associated with an increased risk of cancer, neurological diseases, or injuries, among others. For years, efforts have been made to answer the question regarding the safe amount of alcohol intake, but controversies remain. Observational studies advocate moderate alcohol consumption following a Mediterranean pattern (red wine with meals avoiding binge drinking) as the best option for current drinkers. However, agencies such as the IARC recommend abstention from alcohol as it is a potent carcinogen. In this context, more randomized trial with larger sample size and hard clinical endpoints should be conducted to clarify the available evidence and provide clinicians with support for their clinical practice.

Technological Interventions for the Treatment of Substance Use Disorders

Substance use disorders (SUDs) pose a major public health concern. In recent years, technological (i.e., e-health) interventions have emerged and are increasingly offered in a variety of settings, including substance use treatment. E-health interventions encompass a wide variety of advantages depending on the chosen delivery format. This chapter discusses existing interventions and the effectiveness of delivering them as an e-health intervention, with a focus on randomized controlled trials, for the treatment of alcohol, cannabis, opioid, psychostimulant, or poly-substance use, as well as in transdiagnostic interventions. Based on the literature, suggestions for future research and clinical implications are discussed.

Participant Satisfaction with Computer-Delivered Intervention Components and Its Relation to Alcohol Outcomes

Few computer-delivered brief intervention (CDBI) studies have evaluated participant satisfaction with individual elements of the intervention, or whether participant satisfaction impacts intervention outcomes. Purpose: This factorial trial examined whether subjective reactions to a CDBI for heavy drinking (1) varied depending on the presence versus absence of an animated narrator, a spoken voice, empathic reflections, and motivational interviewing (MI) strategies and (2) were associated with drinking outcomes at 3-month follow-up. Methods: Participants were 352 heavy drinking university students. All participants were randomly assigned to one of 16 versions of a CDBI. After finishing the CDBI, participants completed measures of intervention likability and perceived empathy. Alcohol use outcomes were assessed at 3-month follow-up. Results: CDBI characteristics had minimal effects on participant ratings of likeability and perceived empathy. However, higher likeability ratings were associated with decreases in alcohol use outcomes over the 3-month assessment period. Conclusions: Results indicate that subjective reactions to CDBIs can have important effects on alcohol use outcomes.
