RESUMO
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. In a community sample of 65 individuals with heavy/hazardous alcohol use on the Alcohol Use Disorder Identification Test, we showed good internal consistency reliability, test-retest reliability, and concurrent validity for theoretically aligned measures (e.g., reward drinking and reward responsiveness, relief drinking and depression/anxiety symptoms) of the reward and relief subscales across the six measures. We then used ecological momentary assessment to determine whether reward and relief drinking subscales predicted within-person associations between contextual factors of interest (e.g., negative affect, positive affect, distress intolerance, physical pain, hangover symptoms, social drinking situations, alcohol cues) and same-moment alcohol craving. All six measures demonstrated limited predictive validity for alcohol craving contexts in daily life as assessed via ecological momentary assessment. Despite these findings, reward and relief drinking measures show good reliability and concurrent validity and previously demonstrated clinical utility for predicting response to alcohol use disorder treatments, including naltrexone. Future research should aim to elucidate the mechanisms underlying the association between responses to reward/relief drinking measures and pharmacotherapy outcomes.

RESUMO
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; 77.5 % male; mean age = 42.18 years; 86.5 % Black, 10.8 % non-Hispanic white) that evaluated telephone-based continuing care for a 12- and 24-month period. Cocaine use frequency levels, measured with the Timeline Followback, were (1) abstinence (no past-month cocaine use), (2) low-frequency use (1-4 days of use/month), and (3) high-frequency use (5+ days of use/month). RESULTS: Among those who completed the 12-month follow-up (n = 392), most reduced from high-frequency use at baseline to abstinence at the 12-month follow-up (n = 243; 62.0 %). An additional 21.2 % (n = 83) reported either high-to-low-frequency use (n = 35; 8.9 %) or low use-to-abstinence (n = 48; 12.2 %); 16.8 % of participants (n = 66) did not change or increased their cocaine frequency level. Compared to those who had no change/increases in frequency levels, at least a one-level reduction from baseline to 12-month follow-up (i.e., high-to-low-frequency use, high-to-abstinence, low-to-abstinence) was concurrently associated with lower levels of negative consequences at the 12-month follow-up and prospectively with lower levels of cocaine use and consequences at 24-month follow-up, with effect sizes in the medium-to-large range. Those who reduced to abstinence generally had fewer drug use consequences at the 12-month follow-up than those who reduced to a low-frequency level; however, these groups did not significantly differ on any outcomes at the 24-month follow-up. CONCLUSIONS: Categorical reductions in cocaine use frequency levels, including those short of abstinence, are associated with less cocaine use and lower problem severity up to two years following treatment entry. Low-frequency cocaine use following the initial treatment phase does not appear to forebode worsening functioning, such as escalations in cocaine use.

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. METHODS: Phase 1 (n = 5) involved developing and testing a single introductory digital lesson. Phase 2 included a separate sample (n = 5) and involved testing all 15 digital lessons (each 30- to 45-minutes) over a 6-week period, while also receiving weekly brief phone coaching for motivational/technical support. RESULTS: Across both phases, quantitative ratings (rated on a 5-point scale) were all at or above a 4 (corresponding with 'agree') for key acceptability dimensions, such as usability, understandability, appeal of visual content, how engaging the content was, and helpfulness for recovery. Additionally, in both phases, qualitative feedback indicated that participants particularly appreciated the BOAT (Breath, Observe, Accept, Take a Moment) tool for breaking down mindfulness into steps. Qualitative feedback was used to iteratively refine the intervention. For example, based on feedback, we added a second core mindfulness tool, the SOAK (Stop, Observe, Appreciate, Keep Curious), and we added more example clients and group therapy videos. In Phase 2, 4 out of 5 participants completed all 15 lessons, providing initial evidence of feasibility. Participants reported that the phone coaching motivated them to use the app. The final version of Mindful Journey was a smartphone app with additional features, including brief on-the-go audio exercises and a library of mindfulness practices. Although, participants used these additional features infrequently. CONCLUSIONS: Based on promising initial findings, future acceptability and feasibility testing in a larger sample is warranted. Future versions might include push notifications to facilitate engagement in the additional app features.

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. The ROC task was administered pre- and postintervention to assess changes in cue-induced craving and mindfulness- and reappraisal-based regulation of craving. RESULTS: MBT and CBT-versus control-showed significantly greater reductions in smoking during the intervention phase (baseline to Week 4), corresponding to large (d = -1.08, 95% CI [-1.64, -0.52]) and medium-to-large effect sizes (d = -0.69, 95% CI [-1.22, -0.15]), respectively. During follow-up (Week 4-16), CBT showed significant increases in smoking, whereas MBT and control did not. For the entire study (baseline to Week 16), MBT showed significantly greater reductions in smoking compared to control (d = -1.6, 95% CI [-2.56, -0.66]) but CBT was not significantly different than control (d = -0.82, 95% CI [-1.77, 0.13]). There were no effects on smoking when directly comparing MBT and CBT. Quit rates were low across the sample, with no difference among conditions. MBT and CBT-versus control-significantly reduced cue-induced craving. CBT (but not MBT)-versus control-significantly improved reappraisal-based regulation of craving. Both MBT and CBT-versus control-significantly improved mindfulness-based regulation of craving. CONCLUSIONS: MBT- and CBT-ROC-T may reduce cue-induced craving and smoking, and MBT may be more durable than CBT. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

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. In this open trial, we aimed to evaluate (1) acceptability and feasibility; (2) intervention skill use and its association with state mindfulness in daily life; and (3) pre-to-post changes in target mechanisms and outcomes. Eighteen individuals with past-year AN or past-year atypical AN completed Mindful Courage-Beta over 2 weeks. Participants completed measures of acceptability, trait mindfulness, emotion regulation, eating disorder symptoms, and body dissatisfaction. Participants also completed ecological momentary assessment of skill use and state mindfulness. Acceptability ratings were good (ease-of-use: 8.2/10, helpfulness: 7.6/10). Adherence was excellent (100% completion for foundational module and 96% for mini-modules). Use of the BOAT in daily life was high (1.8 times/day) and was significantly associated with higher state mindfulness at the within-person level. We also found significant, large improvements in the target mechanisms of trait mindfulness (dâ¯=â¯.96) and emotion regulation (dâ¯=â¯.76), as well as significant, small-medium to medium-large reductions in eating disorder symptoms (dsâ¯=â¯.36-.67) and body dissatisfaction (dâ¯=â¯.60). Changes in trait mindfulness and emotion regulation had medium-large size correlations with changes in global ED symptoms and body dissatisfaction (rsâ¯=â¯.43 - .56). Mindful Courage-Beta appears to be promising and further research on a longer, refined version is warranted.

INTRODUCTION: Eating disorders (EDs) have high rates of relapse. However, it is still not clear which factors are the strongest predictors of ED relapse, and the extent to which predictors of relapse may vary due to study and individual differences. 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.g., ED subtype, sample age, length of follow-up, timing of predictor assessment, relapse operationalization). METHODS: A total of 35 papers (effects = 315) were included. We used a multilevel random-effects model to estimate summary study-level effect sizes, and multilevel mixed-effects models to examine moderator effects. RESULTS: Higher level of care, having psychiatric comorbidity, and higher severity of ED psychopathology were associated with higher odds of relapse. Higher leptin, higher meal energy density/variety, higher motivation for change, higher body mass index/weight/body fat, better response to treatment, anorexia nervosa-restricting (vs. anorexia nervosa-binge purge) subtype diagnosis, and older age of ED onset were associated with lower odds of relapse. Several moderators were identified. DISCUSSION: A variety of variables can predict ED relapse. Furthermore, predictors of ED relapse vary among ED subtypes, sample ages, lengths of follow-up, timing of predictor assessments, and relapse operationalization. Future research should identify the mechanisms by which these variables may contribute to relapse.

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 (Nâ¯=â¯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. We conducted analyses both with and without food- and body-related mindfulness items. Central nodes included: describing how one feels in detail, expressing how one feels in words, and feeling guilty about eating due to shape/weight. Bridge nodes connecting higher mindfulness processes with lower ED symptoms included: the eating disorder symptom, being uncomfortable about others seeing one eat, and the mindfulness process, not criticizing oneself for having irrational/inappropriate emotions. Bridge nodes connecting higher mindfulness processes with higher ED symptoms included: noticing sensations of the body moving when walking and noticing how food/drinks affect thoughts, bodily sensations, and emotions. Findings suggest that future research should explore whether mindfulness-based interventions for EDs may be more effective by targeting mindfulness processes related to describing, expressing, and accepting emotions, accepting discomfort when eating with others, and reducing hyper-focus on and reactivity to food-and-body related sensations.

BACKGROUND: Precision medicine approaches attempt to reduce variability in alcohol use disorder (AUD) outcomes by identifying patient characteristics that predict response to a particular treatment. 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. We sought to refine a brief measure of reward/relief drinking and develop cutoff scores to identify reward/relief subgroups that predict pharmacotherapy response. METHODS: The Inventory of Drinking Situations (IDS), used in previous studies to measure reward/relief drinking, was administered to 426 participants (77% male; average age = 45.3) in a clinical trial examining naltrexone and acamprosate. RESULTS: Item response theory and tests of differential item functioning across sex, age, and alcohol dependence severity were used to create a 10-item measure, titled the Reward and Relief IDS (RR-IDS). Cutoff scores on the RR-IDS for the reward/relief drinking subgroups were identified using latent profile and area under the curve analyses. The cutoff scores demonstrated good construct validity. Individuals in the high reward/low relief subgroup who received naltrexone or acamprosate had a decreased likelihood of heavy drinking (large effect sizes) versus those who received placebo. CONCLUSIONS: The RR-IDS is a practical measure for identifying reward/relief subgroups and predicting pharmacotherapy response. Pending replication of these findings, the RR-IDS could be a critical precision medicine tool for prescribing AUD medications.

BACKGROUND: 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. The current study used ecological momentary assessment (EMA) to examine the extent to which momentary mindful awareness, willingness, and values clarity varied within-person, and were associated with craving and likelihood of dietary lapse among weight-loss seeking individuals with overweight/obesity prior to starting a weight loss program. We also examined the extent to which craving was associated with dietary lapse. METHODS: Adults with overweight/obesity (N = 126) completed one week of EMA prior to enrolling in a randomized controlled trial of behavioral weight loss treatments. They responded to EMA questions assessing dietary lapses, craving, mindful awareness, willingness, and values clarity six-times per day. RESULTS: Mindful awareness, willingness, and values clarity demonstrated substantial within-person variability, and higher within-person mindful awareness, willingness, and values clarity were concurrently (but not prospectively) associated with lower craving and likelihood of dietary lapse. Higher craving was concurrently (but not prospectively) associated with higher likelihood of dietary lapse. Between-person, higher mindful awareness, willingness, and values clarity were associated with lower craving and likelihood of dietary lapse, and higher craving was associated with greater frequency of dietary lapses. CONCLUSION: Mindful awareness, willingness, and values clarity vary substantially at the daily level, and may be important mechanisms to target to reduce craving and dietary lapses in the daily lives of individuals with overweight/obesity.
RESUMO
BACKGROUND: Assessment instruments commonly used in clinical trials to measure functional outcomes in substance users may lack sensitivity to detect change during treatment, potentially limiting findings regarding benefits of reduced drug use. 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. Within-person cohen's d' was used to evaluate effect size of change on the Psychiatric Composite Score of the ASI (ASI-Psych) and Global Severity Index (GSI) of the Brief Symptom Inventory, as well as cocaine use. RESULTS: Effect sizes were larger for GSI than ASI-Psych from baseline to week 12 (GSI d' = 0.59; ASI-Psych d' = 0.16), and 6-month follow-up (GSI d' = 0.48; ASI-Psych d' = 0.10). For those with non-zero ASI-Psych at baseline (n = 252), medium effect sizes were found over the 12-week period (d' = 0.53) and 6-month follow-up (d' = 0.47). Effect sizes for change in days of cocaine use were most similar to GSI in either sample. CONCLUSIONS: The ASI Psychiatric Composite Score may have limited sensitivity to detect change in psychiatric functioning among clinical trial participants who reduce cocaine use. It may be useful for detecting change amongst those reporting some psychiatric problems at the start of treatment. Future research should consider an instrument's sensitivity to change when assessing the potential functional benefits of reducing cocaine use.

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. METHOD: Participants (N = 228) were part of a clinical trial evaluating Craving to Quit, a smartphone app for mindfulness training for smoking cessation, compared to an app delivering only ES. All participants were asked to complete 22 days of ES, with up to 6 ES surveys per day, measuring awareness, craving, positive and negative affect and smoking. Data were analyzed using multilevel linear modeling. RESULTS: Both at the within and between-person level, higher awareness was associated with higher positive affect, lower craving and lower negative affect. Lower within-person craving was associated with lower smoking. Within-person awareness, positive and negative affect were not significantly associated with smoking. At the between-person level, higher awareness and higher positive affect, and lower negative affect and lower craving were associated with lower smoking. CONCLUSIONS: Awareness of current experience was related to key psychological variables linked to behavior change in smoking cessation, namely positive and negative affect and craving, among smokers trying to quit. Future studies should test whether learning to increase awareness, such as through mindfulness training, may benefit smokers in treatment.

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. We hypothesize how MBIs-via increasing either mindful awareness or mindful acceptance-may mobilize up to eight associative-learning change mechanisms, two involving Pavlovian learning, and six involving operant learning. We also elaborate on similarities and differences between MBIs and CBT approaches for EDs, as well as opportunities for synergy. Finally, we present recommendations for future research related to the development and evaluation of novel MBI interventions for EDs and the testing of mechanisms and patient-treatment matching hypotheses.

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. PARTICIPANTS: A total of 128 young adult (ages 18-25) heavy drinkers. INTERVENTIONS: Naltrexone versus placebo. MEASUREMENTS: Daily surveys assessed affect, urge, drinking, and context. The Drinking Motives Questionnaire was used to identify phenotypes based on reward (enhancement motives) and relief (coping motives) drinking. FINDINGS: We identified three profiles: "Low reward/Low relief" (14.1%; low enhancement/low coping motives); "Reward drinkers" (62.2%; high enhancement/low coping motives); and "High reward/High relief" (22.7%; high enhancement/high coping motives). Among reward drinkers (versus low profile), naltrexone significantly reduced percent days drinking to intoxication (blood alcohol concentration [BAC] ≥0.08) (PDI) (d = 0.56; 95% CI [0.17, 0.96]) and percent high intensity drinking days (PHID) (8/10 drinks for women/men) (d = 0.32; 95% CI [0.01, 0.68]). Among the high reward/high relief profile drinkers (versus low profile), naltrexone reduced PHID (d = 0.69; 95% CI [0.02, 1.50]). Using profile-informed cutoffs and observed scores (for clinical applicability): (i) among cutoff-derived reward drinkers, we found a medium-to-large (d = 0.66; 95% CI [0.24, 1.16]) and small effect (d = 0.28; 95% CI [0.04, 0.72]) of naltrexone in reducing PDI and PHID, respectively; and (ii) among the cutoff-derived high reward/high relief subgroup, we found a medium-to-large effect (d = 0.63; 95% CI [0.05, 1.1]) of naltrexone in reducing PHID. Among reward drinkers (not other profiles), naltrexone reduced drinking on days a drinking event occurred by weakening the within-day association between positive affect and urges (P < 0.05). CONCLUSIONS: Naltrexone has pronounced effects in reducing risky drinking among young adult reward drinkers (high reward/low relief) by reducing urges on days when individuals have higher positive affect and are exposed to a drinking event. Naltrexone also appears to reduce risky drinking among young adult high reward/high relief drinkers, but not via the same mechanism.

OBJECTIVE: Four decades ago, the "controlled drinking" controversy roiled the alcohol field. Data have subsequently accumulated indicating that nonabstinent alcohol use disorder (AUD) recovery is achievable, but questions remain whether it is sustainable long-term. This study examined whether nonabstinent recovery at 3 years after AUD treatment is associated with better functioning at 10 years after treatment. METHODS: Data were from the 10-year follow-up of Project MATCH (New Mexico site only, nâ =â146; 30.1% female, 58.6% non-White). Recovery was defined by latent profile analyses based on psychosocial functioning and alcohol consumption 3 years after treatment. Drinking practices and consequences, depression, purpose in life, and anger were assessed 10 years after treatment. Distal outcome analyses examined differences in drinking and functional outcomes at 10 years as a function of the 3-year latent profiles. Analyses were preregistered at https://osf.io/3hbxr. RESULTS: Four latent profiles identified at 3 years after treatment (ie, low functioning frequent heavy drinkers, low functioning infrequent heavy drinkers, high functioning heavy drinkers, and high functioning infrequent nonheavy drinkers) were significantly associated with outcomes 10 years after treatment. The 2 high functioning profiles at 3 years had the highest level of psychological functioning at 10 years posttreatment, regardless of alcohol consumption level. Abstinence at 3 years did not predict better psychological functioning at 10 years. CONCLUSIONS: Nonabstinent AUD recovery is possible and is sustainable for up to 10 years after treatment. The current findings align with recent proposals to move beyond relying on alcohol consumption as a central defining feature of AUD recovery.

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. Comparisons were performed on the full sample between those with or without clinically significant levels of alexithymia. For a subsample reporting pain (n = 138), intercorrelations were performed to test whether drug use history, pain catastrophizing, pain acceptance, and alexithymia were related to pain severity and pain interference. Regression analyses were performed to test for serial mediation of pain catastrophizing and pain acceptance on the relationship between alexithymia and pain interference in this subsample. RESULTS: Individuals with alexithymia showed increased pain catastrophizing and interference, and intercorrelations indicated that increased alexithymia was associated with increased pain interference, more pain catastrophizing, and reduced pain acceptance. A serial regression model among a subset of patients with pain indicated that pain catastrophizing and pain acceptance mediated the effect of alexithymia on pain interference. CONCLUSIONS: These findings suggest that alexithymia, as well as both pain catastrophizing and pain acceptance, contribute to interference associated with pain and are potentially important intervention targets among methadone-treated patients with pain.

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 = 38.9; 72.3% female) and COMBINE (N = 1,383; M age = 44.4; 69.1% male). Transitions between heavy and nonheavy drinking within consecutive 2-week periods over a 1-year posttreatment period were characterized for each participant. From this, latent profiles were identified based on participants' initial 2-week heavy drinking status, the number of observed transitions between 2-week periods of relapse and remission, and the average duration of observed remission/relapse episodes. RESULTS: In both MATCH and COMBINE, we identified six profiles: (a) "continuous remission," 25.3% of COMBINE sample/25.3% of MATCH sample; (b) "transition to remission," 19.6%/9.6%; (c) "few long transitions," 15.9%/33.7%; (d) "many short transitions," 13.2%/13.6%; (e) "transition to relapse," 7.2%/7.1%; and (f) "continuous relapse," 18.8%/10.5%. Profiles 1 and 2 had the best long-term outcomes, Profiles 5 and 6 had the worst, and Profiles 3 and 4 fell between these groups. CONCLUSIONS: That many individuals can remit from heavy drinking following one or more relapses to heavy drinking may be of direct interest to individuals in recovery from AUD.

OBJECTIVE: This study examined the cross-sectional associations among pain intensity, pain catastrophizing, and sleep disturbance among patients receiving methadone maintenance treatment (MMT) for opioid use disorder (OUD) and reporting co-occurring chronic pain. MATERIALS AND METHODS: Participants were 89 individuals with OUD and chronic pain drawn from a larger cross-sectional study of 164 MMT patients who completed a battery of self-report measures. The authors conducted 6 mediation models to test all possible pathways (ie, each variable tested as an independent variable, mediator, or dependent variable). RESULTS: The only significant mediation effect was an indirect effect of sleep disturbance on pain intensity through pain catastrophizing. That is, greater sleep disturbance was associated with greater pain catastrophizing, which in turn was associated with greater pain intensity. DISCUSSION: Altogether, findings suggest that the sleep disturbance to pain catastrophizing to pain intensity pathway may be a key mechanistic pathway exacerbating pain issues among MMT patients with OUD and chronic pain. These results suggest that interventions targeting sleep disturbance may be warranted among MMT patients with OUD and chronic pain. Future work in this area with longitudinal data is warranted.

BACKGROUND: No studies have examined long-term changes in substance-related coping skills as a statistical mediator of cognitive-behavioral therapy (CBT) for substance use disorders (SUD). METHODS: We tested both short- and long-term changes in coping as mediators of treatment effects in two trials of in-person and/or computerized CBT for SUD. The first trial included 137 individuals (75 % male; 65.7 % non-White; mean age = 35.9) with drug and/or alcohol use disorders randomized to one of the following: in-person CBT, computer-delivered CBT (CBT4CBT) plus brief monitoring, or treatment-as-usual (TAU). The second trial included 68 individuals (65 % male; 66.2 % non-white; mean age = 42.7) with an alcohol use disorder randomized to one of the following: CBT4CBT plus brief monitoring, CBT4CBT plus TAU, or TAU only. Coping was assessed with the Coping Strategies Scale. Latent growth curve mediational models were conducted, with both short-term (baseline through end-of-treatment) and long-term (baseline through 3-month post-treatment follow-up) changes in coping. RESULTS: There were no mediation effects for short-term changes in coping. However, in both trials, there were significant mediation effects for long-term changes in coping: In trial 1, the effect of CBT4CBT vs. TAU on substance use at the 6-month follow-up was mediated by long-term increases in coping. This same mediation effect was not found for in-person CBT vs. TAU. In trial 2, the effect of CBT4CBT vs. not receiving CBT4CBT on heavy drinking at the 6-month follow-up was mediated by long-term increases in coping. CONCLUSIONS: Long-term increases in coping may be a mechanism of change in computerized CBT for SUD.
