Background And Aims: Craving, the desire to use substances, is a key factor and diagnostic criterion for substance use disorders (SUDs) that predicts substance use. Experiencing affective states, both positive (PA) and negative (NA), are also implicated in SUDs. Yet, the interrelationships among affect, craving, and substance use remain unclear, particularly at the within-person level of analysis.

Previous work examining the extent to which individuals seek alcohol to enhance positive experiences (reward drinking) or relieve aversive states (relief drinking) has shown that reward/relief drinking predicts response to naltrexone and acamprosate treatment for alcohol use disorder. Yet, various measures of reward/relief drinking have been used in prior research, and the comparative psychometric properties of these measures are unknown. Evaluating and comparing the psychometric properties of these reward/relief drinking measures could identify measures with the most promise for translating precision medicine findings to clinical practice.

Background: There is a need to identify clinically meaningful non-abstinent endpoints for cocaine use disorder (CUD) clinical trials. In this study, we sought to replicate and extend prior work validating reductions in cocaine use frequency levels as an endpoint by examining associations between reductions in cocaine use frequency and long-term functioning outcomes.
Methods: We conducted a secondary analysis of two randomized clinical trials (N = 445; 77.
Background/objectives: There is a great unmet need for accessible adjunctive interventions to promote long-term recovery from substance use disorder (SUD). This study aimed to iteratively develop and test the initial feasibility and acceptability of Mindful Journey, a novel digital mindfulness-based intervention for promoting recovery among individuals with SUD.
Patients/materials: Ten adults receiving outpatient treatment for SUD.
We aimed to elucidate the effects of "dose" of a single-session of mindfulness meditation on state mindfulness and affect as well as moderators of effects. 372 adults recruited remotely via Amazon's MTurk platform were randomly assigned to either a: 10-min mindfulness meditation, 20-min mindfulness meditation, 10-min control, or 20-min control. Control conditions were recordings of a National Geographic article.

Objective: Craving predicts smoking, yet existing interventions may not adequately target regulation of craving. We evaluated two versions of regulation of craving-training (ROC-T), a computerized intervention with intensive practice of strategies when exposed to smoking-related images.
Method: Ninety-two nicotine-dependent daily smokers were randomized to mindfulness-based therapy (MBT) ROC-T focusing on mindful acceptance, and cognitive behavioral therapy (CBT) ROC-T focusing on reappraisal or no intervention control.
Anorexia nervosa (AN) is a chronic and debilitating psychiatric disorder. Unfortunately, current treatments are lacking, with only 30-50% of individuals with AN recovering after treatment. We developed a beta-version of a digital mindfulness-based intervention for AN called Mindful Courage-Beta, which includes: (a) one foundational multimedia module; (b) 10 daily meditation mini-modules; (c) emphasis on a core skill set called the BOAT (Breathe, Observe, Accept, Take a Moment); and (d) brief phone coaching for both technical and motivational support.

Objective: We conducted a meta-analysis to quantify and compare which factors predict relapse in EDs and evaluate various potential moderators of these relations (e.
Higher trait mindfulness may be protective against eating disorder (ED) pathology. However, little is understood about which specific mindfulness processes connect to specific ED symptoms. This study (N = 1,056 undergraduates) used network analysis at the symptom/process level to identify: (1) central nodes, or symptoms/processes with the greatest collective connection with all other symptoms/processes; and (2) bridge nodes, or symptoms/processes driving interconnection between mindfulness processes and ED symptoms.

Recent work has examined the extent to which individuals with AUD may seek alcohol to enhance positive experiences (reward drinking) or relieve negative states (relief drinking) and shown that a high reward/low relief phenotype predicts naltrexone treatment response. Yet, limitations of reward/relief drinking measures may hamper efforts to translate findings to clinical practice.
View Article and Find Full Text PDFBackground: Mindful awareness, willingness and values clarity have been examined as protective factors across a wide range of problems, including overweight/obesity. However, these variables have almost exclusively been examined at the trait-level. It is possible that these variables also fluctuate within individuals in daily life, and that these intraindividual fluctuations may in turn be related to food craving and dietary lapse.

This study evaluated the sensitivity of the Addiction Severity Index (ASI) to detect change in psychiatric functioning among cocaine users.
Methods: Data were pooled across five clinical trials for cocaine use disorder (N = 492) that included a 12-week treatment period and 6-month follow-up.

Objective: Mindfulness has received attention in smoking cessation research, yet the mechanisms by which mindfulness may promote smoking cessation are not well understood. Mindfulness training may help individuals increase awareness and respond skillfully to processes that contribute to smoking, such as affective states and craving. This study used experience sampling (ES) to test how awareness was related to craving, positive and negative affect and smoking, in the moment, among smokers in treatment for smoking cessation.

Objectives: The purpose of this study was to examine whether changes in heavy drinking occurring within alcohol treatment predict long-term functioning.
Method: Latent profile analyses were conducted using data from Project MATCH and COMBINE. Observed changes in heavy and nonheavy drinking within consecutive 2-week periods over the respective treatment durations were characterized for each participant and were used to identify latent profiles.
Mindfulness is a two-component skill that includes mindful awareness (attentional monitoring of present moment experience) and mindful acceptance (adopting an attitude of acceptance toward this experience). Although mindfulness-based interventions (MBIs) are efficacious for many conditions, there is a lack of research on MBIs for eating disorders (EDs). We propose that MBIs may be promising for EDs given their potential to mobilize not one, but multiple associative-learning change mechanisms in EDs-defined as adaptive processes of change involving one of two forms of associative-learning: Pavlovian and operant learning.

Background: Regardless of the precise mechanism, all neurodevelopmental models of risk assume that, at the population level, there exist subgroups of individuals that share similar patterns of neural function and development-and that these subgroups somehow relate to psychiatric risk. However, the existence of multiple neurodevelopmental subgroups at the population level has not been assessed previously.
Methods: In the current study, cross-validated latent profile analysis was used to test for the presence of empirically derived, brain-based developmental subgroups using functional magnetic resonance imaging data from 6758 individuals (49.
Aims: Theory-driven, exploratory study to: (i) identify a reward drinking phenotype in young adults; (ii) evaluate this phenotype as a predictor of naltrexone response; and (iii) examine mechanisms of naltrexone in reward drinkers.
Design: Secondary analysis of a randomized controlled trial.
Setting: USA.
Purpose Of Review: Many psychosocial interventions for substance use disorders (SUDs) focus on teaching self-regulation strategies. Research using intensive longitudinal methods (ILM), such as ecological momentary assessment and daily diaries, is critical for elucidating if and how these strategies function as mechanisms of change among individuals with SUDs. We review this emerging area of research.
View Article and Find Full Text PDFObjectives: Mindfulness-based relapse prevention (MBRP) for substance use disorders (SUDs) appears to be particularly effective among individuals with high levels of co-occurring affective symptoms. We sought to understand whether changes in approach and avoidance coping may explain the effects of MBRP among this subpopulation.
Method: The sample included 286 individuals with SUDs randomized to MBRP, relapse prevention (RP), or treatment-as-usual (TAU) as an aftercare treatment.
Objectives: Studying clinical course after alcohol use disorder (AUD) treatment is central to understanding longer-term recovery. This study's two main objectives were to (a) replicate a recent study that identified heterogeneity in patterns of remission from/relapse to heavy drinking during the first year after outpatient treatment in an independent data set and (b) extend these recent findings by testing associations between patterns of remission/relapse and long-term alcohol-related and functioning outcomes.
Method: Latent profile analyses were conducted using data from Project MATCH (N = 952; M age = 38.

Background: Alexithymia, difficulty identifying and describing one's emotions coupled with a tendency to externalize, is a potentially important yet understudied treatment target for patients with opioid use disorder. The aim of this study was to examine the role of alexithymia in pain experience among individuals with opioid use disorder.
Methods: One-hundred-and-sixty-four patients receiving methadone maintenance treatment completed a battery of self-report measures related to alexithymia, drug use, and pain experiences.
