Bayesian Machine Learning Tools for Alcohol Use Disorder Research
Alcohol use disorder (AUD) research faces significant challenges in capturing individual heterogeneity and complex temporal patterns in drinking behaviors. Standard statistical methods fail to account for within-person variability and between-person differences, while existing machine learning algorithms are not designed for hierarchical, longitudinal data structures common in AUD research. We developed a comprehensive R package implementing 30 B…
A clarion call to the addiction science community
Keep on Keeping on? Patient Factors Predicting Discontinuation in Alcohol Use Disorder Treatment
BACKGROUND: A substantial portion of patients with alcohol use disorder (AUD) discontinue treatment. More knowledge of predictors of discontinuation is important for clinicians in preventing premature discontinuation and tailoring treatment to the patient. AIM: To investigate predictors of completion versus discontinuation in a sample from a multi-site study on outcome predictors of AUD treatment. METHODS: The analyses included 136 patients from …

A continuum model of alcohol use and problems can advance public health goals without undermining treatment agendas. Reply to commentaries
We wish to thank the authors for their thought-provoking commentaries and engagement with the importance of a continuum model of alcohol use and problems. We strongly agree with Callinan and Room (
Should we promote alcohol problems as a continuum? Implications for policy and practice
The highly heterogeneous nature of alcohol use and problems has presented significant challenges to those attempting to understand, treat or prevent what is commonly termed alcohol use disorder (AUD). However, any attempts to capture this complex phenomenon, including the various current criterion of AUD, come with a number of limitations. One particular limitation has been how alcohol problems are represented or understood in ways which do not c…
Whole person recovery from substance use disorder
Individual pathology-based approaches to understanding and promoting substance use disorder recovery are too narrowly focused. This review calls for greater consideration of the dynamic behavioral ecological and temporally extended contexts that contribute to harmful substance use and systemic changes necessary to promote and sustain recovery
Internalized shame among justice-involved women in substance use disorder treatment
Shame is one of the leading barriers to successful recovery in substance use treatment settings. This secondary analysis study examined measurement invariance of the Internalized Shame Scale (ISS) and explored changes in shame during treatment. Participants (N=105) in the parent study were recruited from a nonprofit residential treatment center for justice-involved women and were randomized to receive mindfulness-based relapse prevention or relap…
Initial psychometric testing of the harm reduction self-efficacy scale
Abstinence self-efficacy, belief in one's ability to abstain, has been identified as a predictor of substance use behavior change. Yet, many people who use substances do not want to abstain. Self-efficacy for achieving a range of goals (i.e., abstinence or harm reduction) would be more widely applicable and might also predict substance use behavior change. The current study reports on the development of the Harm Reduction Self-Efficacy Scale (HRS…
The daily association between affect and alcohol use
Influential psychological theories hypothesize that people consume alcohol in response to the experience of both negative and positive emotions. Despite two decades of daily diary and ecological momentary assessment research, it remains unclear whether people consume more alcohol on days they experience higher negative and positive affect in everyday life. In this preregistered meta-analysis, we synthesized the evidence for these daily associatio…
An R Shiny App for Sensitivity Analysis for Latent Growth Curve Mediation
Mechanisms of behavior change are the processes through which interventions are hypothesized to cause changes in outcomes. Latent growth curve mediation models (LGCMM) are recommended for investigating the mechanisms of behavior change because LGCMM models establish temporal precedence of change from the mediator to the outcome variable. The Correlated Augmented Mediation Sensitivity Analyses (CAMSA) App implements sensitivity analysis for LGCMM …
Alcohol use disorder relapse factors
For decades predictors of alcohol use disorder (AUD) relapse have been studied, and around 40 different clinical and demographic relapse determinants have been identified. This paper aims to investigate the relationship of two of these AUD relapse factors, namely craving and meaning in life (MiL). We hypothesized that greater meaning in life would be associated with lower cravings and lower relapse rates. An AUD subsample of 81 patients within a …
Alcohol use disorder conceptualizations and diagnoses reflect their sociopolitical context
The present paper highlights how alcohol use disorder (AUD) conceptualizations and resulting diagnostic criteria have evolved over time in correspondence with interconnected sociopolitical influences in the United States. We highlight four illustrative examples of how DSM-defined alcoholism, abuse/dependence, and AUD have been influenced by sociopolitical factors. In doing so, we emphasize the importance of recognizing and understanding such soci…
Latent Class Mediation
Latent class mediation modeling is designed to estimate the mediation effect when both the mediator and the outcome are latent class variables. We suggest using an adjusted one-step approach in which the latent class models for the mediator and the outcome are estimated first to decide on the number of classes, then the latent class models and the mediation model are jointly estimated. We present both an empirical demonstration and a simulation s…
Individual and Community Social Determinants of Health and Recovery from Alcohol Use Disorder Three Years following Treatment
Prior research on recovery from alcohol use disorder (AUD) has often focused on individual-level factors that promote recovery. Given systemic health inequities, it is also important to study community-level social determinants of health (SDOH) that may promote recovery from AUD. This study extended prior work examining individual profiles of recovery from AUD to assess how individual and community SDOH at the time of treatment entry were associa…
Patterns of Polysubstance Use among Adults with Tranquilizer Misuse
Background: The misuse of benzodiazepine tranquilizers is prevalent and is associated with increased risk of overdose when combined with other substances. Yet, little is known about other substance use among those who misuse tranquilizers. Objectives: This study characterized subgroups of individuals with tranquilizer misuse, based on patterns of polysubstance use. Methods: Data were extracted from the 2015–2017 National Survey on Drug Use and He…
Understanding alcohol harm reduction behaviors from the perspective of self-determination theory
The evidence for the efficacy of harm reduction approaches to harmful alcohol use has accumulated over the past 30 years. Self-determination theory (SDT; Ryan and Deci 2017) offers a useful framework for understanding why people engage in alcohol harm reduction behaviors, as well as for delineating active ingredients of harm reduction interventions and individual characteristics that influence response to intervention. In the current paper, we so…

Latent Profile Analysis of Alcohol Consumption and Sexual Attitudes Among College Women
This study used latent profile analysis (LPA) to identify at-risk profiles of college freshman women ( n = 481) using self-reports of alcohol consumption and sociosexuality. Analyses resulted in three profiles labeled low alcohol use-low sociosexuality, high alcohol use-medium sociosexuality, and high alcohol use-high sociosexuality. Baseline victimization predicted latent profile membership. More severely victimized women were more likely to be …
Viability of the World Health Organization quality of life measure to assess changes in quality of life following treatment for alcohol use disorder
Relative Efficacy of Mindfulness-Based Relapse Prevention, Standard Relapse Prevention, and Treatment as Usual for Substance Use Disorders
clinicaltrials.gov Identifier: NCT01159535
Relapse prevention
The term "relapse prevention" drew great criticism and was not generally accepted when it was initially introduced in the early 1980s. The idea of talking with clients about the possibility of relapse was an incredibly radical idea until the pioneering work on relapse prevention by Alan Marlatt and his colleagues challenged the prevailing disease conceptualization of addictions and provided a revolutionary perspective that focused on understandin…

Memory and Reasoning Abilities Assessed by the Universal Nonverbal Intelligence Test
The Universal Nonverbal Intelligence Test (UNIT) is an important advancement in intelligence assessment, but the equal-weighting method used to compute scores for the memory and reasoning abilities results in some psychometric weaknesses. The equally weighted memory and reasoning scores are highly correlated, leading to a lack of discriminant validity, a potential lack of incremental validity, and poor reliability for their score differences. Rel…
Reliability of Scores from the Eysenck Personality Questionnaire
A reliability generalization study was conducted on data from 69 samples found in 44 studies that employed the Psychoticism (P), Extraversion (E), Neuroticism (N), and Lie (L) scales of the Eysenck Personality Questionnaire (EPQ) or EPQ-Revised. The reliability of the scores varied considerably between scales, with P scores tending to have the lowest reliability. Hierarchical regression analyses revealed that a larger standard deviation of scores…
Relapse Prevention for Alcohol and Drug Problems
Defining Relapse from a Harm Reduction Perspective
In the treatment of addictions, engaging in any substance use following treatment is often viewed as a treatment failure. This paper provides theoretical and empirical support for a harm reduction approach to the evaluation of treatment outcomes. Such an approach focuses on consequences associated with the post-treatment drinking, without using rigid definitions of “success”; or “failure.”; Harm reduction approaches to alcohol treatment are intro…

Mindfulness-Based Relapse Prevention for Substance Use Disorders
The current study is the first randomized-controlled trial evaluating the feasibility and initial efficacy of an 8-week outpatient Mindfulness-Based Relapse Prevention (MBRP) program as compared to treatment as usual (TAU). Participants were 168 adults with substance use disorders who had recently completed intensive inpatient or outpatient treatment. Assessments were administered pre-intervention, post-intervention, and 2 and 4 months post-inter…
