RESUMEN

Food addiction (FA) and alcohol misuse tend to co-occur, which suggests shared factors in the etiology and persistence of these health behaviors. One shared factor that has been linked to both is impulsivity, a multidimensional construct reflecting multiple facets of self-regulatory capacity. However, co-occurrence also raises issues of possible confounding if both domains are not considered concurrently, and the intersection between FA, alcohol misuse, and impulsivity has not been well characterized empirically. Therefore, the current study examined the intersection of FA, alcohol consequences, and multiple indicators of impulsivity. Participants were emerging adults reporting regular heavy episodic drinking recruited from Hamilton, Ontario (N = 730; ages 19.5-23). Participants completed measures of FA, alcohol problems, impulsive personality traits (i.e., Barratt Impulsiveness Scales, UPPS-P Impulsive Behavior Scales), impulsive choice (i.e., delay discounting), impulsive action (i.e., Go/NoGo task). Findings revealed a significant association between FA and alcohol-related consequences and both shared similar associations with specific impulsive personality traits (Positive and Negative Urgency, Lack of Premeditation, Motor and Attentional Impulsivity). However, alcohol-related consequences were uniquely associated with other impulsive personality traits (Lack of Perseverance, Sensation Seeking, Non-planning impulsivity) and impulsive choice, and FA was uniquely associated with impulsive action. Beyond alcohol-related consequences, FA was associated with additional variance in measures of impulsive personality traits (Positive and Negative Urgency, Lack of Premeditation, Motor Impulsivity, and Attentional Impulsivity) and impulsive action, but not impulsive choice. Overall, the current study reveals several common self-regulatory processes associated with both adverse drinking consequences and FA, and that the risk of inadvertent confounding appears to be limited.

RESUMEN

Objective: Adolescence is a period during which youth may begin experimenting with substances. Youth with overweight or obesity may be at increased risk for substance use, including cigarette smoking. Understanding the associations between smoking and excess weight and the pathways associated with increased likelihood for smoking initiation is of particular importance given the increased risk for negative health outcomes associated with each. Methods: Using longitudinal panel data from 1,023 middle school youth (baseline age M = 12.5, 52% female), we tested whether smoking initiation was concurrently and prospectively predicted by self-reported body mass index (BMI) and whether self-esteem for physical appearance (SEPA) mediated the effect of BMI on risk of early initiation. Results: BMI predicted smoking initiation concurrently and prospectively in unadjusted models. In adjusted models, SEPA mediated the effects of BMI on smoking initiation. Bootstrapped mediation results indicated that the positive relationship between BMI and subsequent smoking initiation was significantly mediated by lower SEPA (B =.10, 95% confidence interval [0.01, 0.22]). Conclusions: Adolescents who have overweight or obesity are more likely to feel negatively about their appearance and bodies, and this negative perception may result in experimentation with cigarettes. Cigarettes may be used by youth with overweight or obesity in an effort to manage weight, to cope with low self-esteem or for other reasons. Future research should explore the motives and psychosocial context of smoking initiation among adolescents with overweight/obesity further (e.g., with whom they first try smoking, perceived benefits of smoking).

RESUMEN

BACKGROUND: Contingency management (CM) is one of the only behavioral interventions shown to be effective for the treatment of opioid use disorders when delivered alone and in combination with pharmacotherapy. Despite extensive empirical support, uptake of CM in community settings remains abysmally low. The current study applied user-centered design principles to gather qualitative data on familiarity with CM, current clinical practice, and preferences regarding the implementation of CM in community-based opioid treatment programs. METHODS: Participants were 21 leaders and 22 front-line counselors from 11 community-based opioid treatment programs. Semi-structured interviews were about 45 min long. Transcripts from each interview were coded by independent raters and analyzed using a reflexive team approach. Frequencies of responses were tallied, and queries were run in NVivo to identify exemplar quotes for each code. RESULTS: Results indicated low familiarity with CM, with less than half of the respondents defining CM correctly and over 40% of respondents declining to answer/ did not know. Abstinence was the most commonly recommended CM target, yet over 70% of respondents indicated that urine screens only occurred monthly. Attendance was also a popular recommendation, with respondents suggesting a range of possible indices including counseling, dosing, and/or case management sessions. Regarding the ideal role to administer CM prizes, program directors and supervisors were most commonly recommended, closely followed by front-line counselors. The most commonly suggested strategies to afford CM incentives included soliciting community donations and offering non-financial incentives. CONCLUSIONS: User design principles to understand workflow constraints, target user needs, and simplify the intervention guided this qualitative investigation of CM implementation in opioid treatment programs. Findings highlighted the potential value of flexible, organization-specific definitions of CM attendance and non-financial incentives, as well as active involvement of clinical leaders and supervisors to promote buy in among staff/patients. Respondents were generally optimistic about their ability to fundraise or solicit donations to overcome cost-related barriers of CM. Implications for CM implementation strategies, including the use of targeted leadership coaching focused on sustainability, are explored.

RESUMEN

INTRODUCTION: A cigarette purchase task (CPT) is a behavioral economic measure of the reinforcing value of smoking in monetary terms (ie, cigarette demand). This study investigated whether cigarette demand predicted response to contingent monetary rewards for abstinence among individuals with substance use disorders. It also sought to replicate evidence for greater price sensitivity at whole-dollar pack price transitions (ie, left-digit effects). METHODS: Participants (N = 338) were individuals in residential substance use disorder treatment who participated in a randomized controlled trial that compared contingent vouchers to noncontingent vouchers for smoking abstinence. Baseline demand indices were used to predict number of abstinent days during the 14-day voucher period (after the reduction lead-in) and at 1 and 3 months afterward. RESULTS: Demand indices correlated with measures of smoking and nicotine dependence. As measured by elasticity, intensity and O max, higher demand significantly predicted fewer abstinent exhaled carbon monoxide readings during voucher period for individuals in the noncontingent vouchers condition. Breakpoint exhibited a trend-level association with abstinent exhaled carbon monoxide readings. Demand indices did not predict abstinence in the contingent vouchers group, and did not predict abstinence at 1- and 3-month follow-ups. Left-digit price transitions were associated with significantly greater reductions in consumption. CONCLUSIONS: The association of cigarette demand with smoking behavior only in the group for whom abstinence was not incentivized indicates that CPT assesses the value of smoking more than the value of money per se and that vouchers counteract the effects of the intrinsic reinforcing value of cigarettes. Results provide initial short-term evidence of predictive validity for the CPT indices. IMPLICATIONS: This study provides the first evidence of the validity of the CPT for predicting early response to brief advice for smoking cessation plus nicotine replacement in smokers with substance dependence. However, demand for cigarettes did not predict voucher-based treatment response, indicating that incentives serve as a powerful motivator not to smoke that acts in opposition to the intrinsic reinforcing value of cigarettes and that the indices reflect the value of smoking more than the value of money per se.

RESUMEN

BACKGROUND: Mindfulness has been identified as a promising strategy for managing cravings for alcohol and other drugs, but little controlled experimental research has directly studied whether this approach is effective. The current study systematically examined the effects of an acute mindfulness manipulation on craving for alcohol during prolonged exposure to alcohol cues. METHODS: Heavy drinkers (N = 84, 50% male) underwent a prolonged alcohol cue exposure paradigm in a simulated bar environment and received either a mindfulness-based strategy, a distraction (DST)-based strategy (active control), or no strategy (passive control) to cope with alcohol cravings and discomfort associated with craving. RESULTS: No baseline differences were present between conditions. Manipulation checks revealed that participants in the 2 active conditions reported using the recommended strategies. Across groups, the initial exposure to alcohol cues was associated with significant increases in craving, urge distress, and heart rate. Mixed analyses of variance on these indices following the experimental manipulation revealed significant differences based on condition over the course of the bar laboratory protocol. The DST strategy was significantly more effective at acutely reducing craving and urge distress than the other 2 conditions, which did not significantly differ from each other. CONCLUSIONS: Contrary to our prediction, these findings suggest that an acute DSTstrategy is beneficial for coping with alcohol cravings. The potential importance of protracted mindfulness training to detect significant effects on in vivo craving, additional implications, and methodological considerations are discussed.

RESUMEN

OBJECTIVE: Impulsive personality traits have been robustly associated with alcohol and drug misuse, but have received little attention in the context of food addiction. The goal of the current study was to examine the interrelationships between impulsive personality traits, food addiction, and Body Mass Index (BMI), including indirect pathways of influence. METHOD: Participants (N = 233) completed the Yale Food Addiction Scale (YFAS) to assess patterns of addictive consumption of food, the upps-p impulsivity scale to assess impulsive personality traits, and provided weight and height to generate BMI. RESULTS: Significant positive associations were found between facets of impulsivity, food addiction symptoms, and BMI. Impulsivity was found to be indirectly associated with BMI by way of associations with addictive consumption of food. In particular, an inclination toward behaving irrationally while experiencing negative mood states (Negative Urgency) and low levels of task persistence (lack of Perseverance) were significantly associated with food addiction directly and that relationship was responsible for their relationship to BMI. CONCLUSIONS: Dispositional impulsivity, routinely associated with high-risk behaviors including addictive consumption of alcohol and drugs, may be an important risk factor when considering tendency to engage in addictive consumption of food. Monitoring food addiction symptoms early may help reduce the likelihood that compulsive food consumption patterns result in weight gain and obesity. Methodological considerations are discussed.

RESUMEN

Impulsivity is a multifaceted construct that has been linked to dysregulated eating and problematic alcohol use. The UPPS model identifies five personality-based impulsivity traits that have unique predictive utility: Negative Urgency, Perseverance, Premeditation, Sensation Seeking, and Positive Urgency. Delayed reward discounting (DRD) is an index of impulsive decision making characterized by preference for smaller immediate gains at the cost of larger delayed gains. In the current study, we sought to refine the influence of impulsive personality traits and DRD on disordered eating patterns and problematic drinking. One hundred and eight treatment-seeking heavy drinkers were assessed for UPPS impulsivity traits, DRD, disordered eating, alcohol use, and demographic information. With regard to disordered eating patterns, DRD predicted higher levels of Dietary Restraint and Weight and Shape Concerns. Negative Urgency predicted binge eating and Weight and Shape Concerns. Positive Urgency predicted Eating Concerns. Female sex predicted Eating, Weight, and Shape Concerns. When considering problematic alcohol use, only Negative Urgency and Sensation Seeking were predictive. This is the first study to examine both personality-based impulsivity and DRD in relation to pathological eating and drinking behavior. The results suggest the importance of disentangling the contributions of various impulsivity constructs on dysregulated eating.

RESUMEN

INTRODUCTION: Individuals with obesity who smoke cigarettes have increased risk of morbidity and mortality. The goal of the current study was to inform the development of a multiple health behavior change intervention designed to facilitate smoking cessation while also targeting weight gain. METHODS: Four qualitative focus groups were conducted with individuals who smoked cigarettes and had overweight or obesity (n = 16) to explore the combined effects of smoking and obesity, past attempts to quit smoking or lose weight, and preferences for a combined health intervention. RESULTS: Focus groups converged on five themes including: the interactive effects of weight and smoking; lack of experience with evidence-based weight loss approaches; a desire and expectation to lose weight quickly; rapid weight gain during past attempts at smoking cessation; and interest in a multiple health behavior change intervention with weight management preceding smoking cessation and an emphasis on planning for the future and receiving encouragement and support. CONCLUSIONS: Groups provided insight into key topics to highlight in a combined intervention and key issues that have interfered with success in both domains.

RESUMEN

Hypothetical purchase tasks assess substance demand, but the length of purchase tasks makes repeated assessment of state-dependent changes in demand difficult, often limiting clinical utility. Although brief assessments of alcohol and cigarette demand exist, brief measures of cannabis demand do not. College students (N = 209, Mage = 19.92, SD = 1.45; 63% female; 56.9% non-Hispanic Caucasian) who reported using cannabis at least 3 days in the past month, completed an online survey including the full-length marijuana purchase task (MPT), a three-item brief assessment of marijuana demand (BAMD) assessing intensity, Omax and breakpoint, and cannabis use outcomes. Convergent and divergent validity were examined. Independent samples t tests compared demand on the BAMD and MPT based on presence or absence of cannabis use disorder (CUD) symptoms, and one-way between-subject analyses of variance compared effects of CUD severity (mild/moderate/severe) on BAMD indices. All indices were significantly correlated across both assessment measures (ps < .01). Similarly, all indices on both demand measures were significantly correlated with craving, CUD severity, and cannabis-related consequences (ps < .01); whereas only intensity and Omax were significantly correlated with cannabis use frequency (ps < .01). Individuals with (vs. without) CUD symptoms reported significantly greater intensity and Omax (ps < .01) and significant differences in CUD severity on BAMD indices were found as well (ps < .05). The BAMD demonstrated convergent and divergent validity with the MPT. Findings suggest that brief cannabis demand can be easily assessed as an indicator for high-risk cannabis use. Thus, the BAMD may be a useful and clinically relevant tool to assess cannabis demand in real-world settings. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMEN

People with schizophrenia (SCZ) have a shorter life expectancy than those without psychiatric conditions. Of note, people with SCZ have high rates of cigarette smoking, physical inactivity, and obesity. These factors all coalesce to contribute to compromised health in this population, with smoking as a primary contributor. Therefore, it is paramount to develop effective smoking cessation strategies for this population. The purpose of this study was to investigate whether walking at a brisk pace, relative to engaging in passive activity, would reduce acute cigarette craving, nicotine withdrawal, and negative affect (NA) among people with SCZ who smoke cigarettes. Using a within-subjects design, twenty participants completed four laboratory sessions with condition sequence counterbalanced: 1) exposure to smoking cues + treadmill walking, 2) exposure to neutral cues + treadmill walking, 3) exposure to smoking cues + passive/sedentary activity, 4) exposure to neutral cues + passive/sedentary activity. Relative to sedentary activity, walking resulted in greater decreases in nicotine withdrawal but did not significantly affect craving or NA. These results did not vary as a function of cue type. These findings suggest that walking may be a helpful strategy to reduce acute nicotine withdrawal symptoms among people with SCZ. However, it should be used in conjunction with other strategies for smoking cessation.

RESUMEN

INTRODUCTION: The role of craving in nicotine dependence remains controversial and may be a function of measurement challenges. The current study used behavioral economic approach to test the hypotheses that subjective craving from acute withdrawal and exposure to tobacco cues dynamically increases the relative value of cigarettes. METHODS: Using a 2 (1-hr/12-hr deprivation) × 2 (neutral/tobacco cues) within-subjects design, 33 nicotine dependent adults completed 2 laboratory sessions. Assessment included subjective craving and behavioral economic indices of cigarette demand, namely Intensity (i.e., cigarette consumption at zero cost), O(max) (i.e., maximum total expenditure), Breakpoint (i.e., highest acceptable price for cigarettes), P(max) (i.e., price at which consumption becomes sensitive to price), and elasticity (i.e., price sensitivity). Behavioral economic indices were generated using a Cigarette Purchase Task in which participants selected between cigarettes for a subsequent 2-hr self-administration period and money. RESULTS: Main effects of deprivation and tobacco cues were present for subjective craving and multiple behavioral economic indices of cigarette demand. Interestingly, deprivation significantly increased Breakpoint (p ≤ .01) and P(max) (p ≤ .05) and had trend-level effects on Intensity and O(max) (p ≤ .10); whereas cues significantly reduced elasticity (p ≤ .01), reflecting lower sensitivity to increasing prices. Heterogeneous associations were evident among the motivational variables but with aggregations suggesting variably overlapping motivational channels. CONCLUSIONS: These findings further support a behavioral economic approach to craving and a multidimensional conception of acute motivation for addictive drugs. Methodological considerations, including potential order effects, and the need for further refinement of these findings are discussed.

RESUMEN

Although many women quit smoking while pregnant, rates of relapse after delivery are high. We examined the effectiveness of motivational interviewing (MI) in maintaining postpartum abstinence from smoking among pregnant women who recently quit smoking (N = 382), randomized to receive five brief MI phone counseling calls or to a prenatal and postpartum care as usual control condition. Relapse to smoking was assessed at 3, 6, and 12 months postpartum based on self-report and urine cotinine. Cox regressions compared conditions on relapse outcomes and hazard ratio of total number of MI calls was examined to probe dose-response effects. Results revealed no difference in the hazard ratio of relapse between treatment condition and no dose-response effect of total number of MI calls. Phone counseling in the prenatal and postpartum period did not facilitate maintenance of abstinence among new mothers. Considerations for future intervention development studies on relapse prevention during the postpartum period are discussed.

RESUMEN

Large proportions of smokers are unsuccessful in evidence-based smoking cessation treatment and identifying prognostic predictors may inform improvements in treatment. Steep discounting of delayed rewards (delay discounting) is a robust predictor of poor smoking cessation outcome, but the underlying neural predictors have not been investigated. Forty-one treatment-seeking adult smokers completed a functional magnetic resonance imaging (fMRI) delay discounting paradigm prior to initiating a 9-week smoking cessation treatment protocol. Behavioral performance significantly predicted treatment outcomes (verified 7-day abstinence, n = 18; relapse, n = 23). Participants in the relapse group exhibited smaller area under the curve (d = 1.10) and smaller AUC was correlated with fewer days to smoking relapse (r = 0.56, p < 0.001) Neural correlates of discounting included medial and dorsolateral prefrontal cortex, posterior cingulate, precuneus and anterior insula, and interactions between choice type and relapse status were present for the dorsolateral prefrontal cortex, precuneus and the striatum. This initial investigation implicates differential neural activity in regions associated with frontal executive and default mode activity, as well as motivational circuits. Larger samples are needed to improve the resolution in identifying the neural underpinnings linking steep delay discounting to smoking cessation.

RESUMEN

Objective: To examine if reduced financial strain and higher educational attainment would confer less advantage for successful cessation among African Americans than for White individuals. Design: A secondary data analysis of the Quit2Live study, a smoking cessation intervention for individuals who smoke. Setting: Recruited participants from a metropolitan city in the Midwest. Participants: The sample included 224 African American and 225 White individuals who smoke. Main Outcome Measures: Our outcome variable was cotinine-verified smoking abstinence at the end-of-treatment (week 12). Our explanatory variables were a combination of financial strain (high, low) and educational attainment (high, low). Methods: We implemented a logistic regression analysis and a two-way interaction of the combined financial strain and educational attainment variable and race on smoking abstinence. Results: About 25% of the study participants were low financial strain and high education, 41% high financial strain and high education, 23% high financial strain and low education, and 11% low financial strain and low education. A greater proportion of African Americans vs Whites were in the high financial strain/low educational attainment category (28% vs 18%, P = .01). Participants with high financial strain and low educational attainment had substantially lower odds of abstinence (OR = .29 [95% CI: .12, .68]) compared to participants with low financial strain and high educational attainment. Contrary to our hypothesis, race did not moderate this association. Conclusion: Findings highlight the constraining role of high financial strain and low educational attainment, irrespective of race, on smoking abstinence among smokers actively engaged in a quit attempt.

RESUMEN

Behavior therapy implementation relies in part on training to foster counselor skills in preparation for delivery with fidelity. Amidst Covid-19, the professional education arena witnessed a rapid shift from in-person to virtual training, yet these modalities' relative utility and expense is unknown. In the context of a cluster-randomized hybrid type 3 trial of contingency management (CM) implementation in opioid treatment programs (OTPs), a multi-cohort design presented rare opportunity to compare cost-effectiveness of virtual vs. in-person training. An initial counselor cohort (n = 26) from eight OTPs attended in-person training, and a subsequent cohort (n = 31) from ten OTPs attended virtual training. Common training elements were the facilitator, learning objectives, and educational strategies/activities. All clinicians submitted a post-training role-play, independently scored with a validated fidelity instrument for which performances were compared against benchmarks representing initial readiness and advanced proficiency. To examine the utility and expense of in-person and virtual trainings, cohort-specific rates for benchmark attainment were computed, and per-clinician expenses were estimated. Adjusted between-cohort differences were estimated via ordinary least squares, and an incremental cost effectiveness ratio (ICER) was calculated. Readiness and proficiency benchmarks were attained at rates 12-14% higher among clinicians attending virtual training, for which aggregated costs indicated a $399 per-clinician savings relative to in-person training. Accordingly, the ICER identified virtual training as the dominant strategy, reflecting greater cost-effectiveness across willingness-to-pay values. Study findings document greater utility, lesser expense, and cost-effectiveness of virtual training, which may inform post-pandemic dissemination of CM and other therapies.

RESUMEN

BACKGROUND AND AIMS: Parallels between the persistent overconsumption of food and addictive drugs have given rise to the notion of food addiction. In a large community sample of Canadian adults, the current study examined the prevalence of food addiction and its relationship with obesity, quality of life and multiple indicators of impulsivity. A secondary goal was to analyze differences between obese and non-obese individuals with and without food addiction. DESIGN: Cross-sectional in-person assessment. SETTING: Hamilton, Ontario, Canada. PARTICIPANTS: A total of 1432 community adults (age = mean ± standard deviation = 38.93 ± 13.7; 42% male) recruited from the general community using print, bus and internet advertisements. MEASUREMENTS: Yale Food Addiction Scale 2.0, anthropometrics (including body mass index), body composition (e.g. body fat, muscle mass, body water), World Health Organization Quality of Life scale and impulsivity measures, including impulsive personality traits, delay discounting and behavioral inhibition. FINDINGS: The prevalence of food addiction was 9.3% and substantially below that of obesity (32.7%), although food addiction was significantly more common among obese individuals (18.5%, P < 0.001). Food addiction was associated with significantly lower quality of life in all domains (ßs = -0.21 to -0.34, Ps < 0.001) and significantly higher impulsive personality traits, particularly negative and positive urgency (ßs = 0.37 and 0.30, Ps < 0.001). Subgroup contrasts within both the obese and non-obese strata revealed that food addiction was associated with significantly lower quality of life in all domains (Ps < 0.001). Food addiction among non-obese individuals was also associated with higher body mass index (P < 0.001). CONCLUSION: In a general community sample, food addiction was present in slightly fewer than one in 10 individuals, approximately one-third the prevalence of obesity, but with twice the prevalence among obese individuals. Food addiction appears to be associated with substantively lower quality of life and elevations in impulsivity, particularly in deficits in emotional regulation.

RESUMEN

Contingency management (CM) has robust evidence of effectiveness as an adjunct to medication for opioid use disorders. However, CM implementation in opioid treatment programs has been limited by a myriad of well-documented barriers. One relatively unexplored barrier that may hinder CM implementation is health professional stigma toward patients with opioid use disorders. Qualitative interviews were conducted with 43 health professionals (21 leaders, 22 front-line counselors) from 11 different opioid treatment programs across Rhode Island to explore their familiarity with CM and to elucidate barriers and facilitators to CM implementation. Interviews were transcribed and coded by 3 independent raters using a reflexive team approach. Transcripts were analyzed for both a priori and emergent themes. Health professional stigma was identified as an emergent major theme with 4 distinct subthemes: (a) distrust of patients (44%, N = 19); (b) infantilizing views about patients (19%, N = 8); (c) belief that patients do not deserve prizes (19%, N = 8); and (d) recognition of patient self-stigma and community-based stigma (23%, N = 10). In addition, we identified multiple instances of health professional use of potentially stigmatizing language toward patients with opioid use disorders via terms such as drug abuser, addict, and clean or dirty urine screens (70%, N = 30). Stigma themes were identified in 86% of the transcripts, highlighting potential targets for multilevel implementation strategies. Findings of this study suggest that multiple types of health professional stigma should be considered and proactively addressed in efforts by psychologists to implement CM and other evidence-based interventions in opioid treatment programs.

RESUMEN

BACKGROUND: Opioid-related overdoses and harms have been declared a public health emergency in the United States, highlighting an urgent need to implement evidence-based treatments. Contingency management (CM) is one of the most effective behavioral interventions when delivered in combination with medication for opioid use disorder, but its implementation in opioid treatment programs is woefully limited. Project MIMIC (Maximizing Implementation of Motivational Incentives in Clinics) was funded by the National Institute on Drug Abuse to identify effective strategies for helping opioid treatment programs improve CM implementation as an adjunct to medication. Specific aims will test the impact of two different strategies on implementation outcomes (primary aim) and patient outcomes (secondary aims), as well as test putative mediators of implementation effectiveness (exploratory aim). METHODS: A 3-cohort, cluster-randomized, type 3 hybrid design is used with the opioid treatment programs as the unit of randomization. Thirty programs are randomized to one of two conditions. The control condition is the Addiction Technology Transfer Center (ATTC) Network implementation strategy, which consists of three core approaches: didactic training, performance feedback, and on-going consultation. The experimental condition is an enhanced ATTC strategy, with the same core ATTC elements plus two additional theory-driven elements. The two additional elements are Pay-for-Performance, which aims to increase implementing staff's extrinsic motivations, and Implementation & Sustainment Facilitation, which targets staff's intrinsic motivations. Data will be collected using a novel, CM Tracker tool to document CM session delivery, session audio recordings, provider surveys, and patient surveys. Implementation outcomes include CM Exposure (number of CM sessions delivered per patient), CM Skill (ratings of CM fidelity), and CM Sustainment (number of patients receiving CM after removal of support). Patient outcomes include self-reported opioid abstinence and opioid-related problems (both assessed at 3- and 6-months post-baseline). DISCUSSION: There is urgent public health need to improve the implementation of CM as an adjunct to medication for opioid use disorder. Consistent with its hybrid type 3 design, Project MIMIC is advancing implementation science by comparing impacts of these two multifaceted strategies on both implementation and patient outcomes, and by examining the extent to which the impacts of those strategies can be explained by putative mediators. TRIAL REGISTRATION: This clinical trial has been registered with clinicaltrials.gov (NCT03931174).

RESUMEN

Value based choice and compulsion theories of addiction offer distinct explanations for the persistence of alcohol use despite harms. Choice theory argues that problematic drinkers ascribe such high value to alcohol that costs are outweighed, whereas compulsion theory argues that problematic drinkers discount costs in decision making. The current study evaluated these predictions by testing whether alcohol use disorder (AUD) symptom severity (indexed by the AUDIT) was more strongly associated with the intensity item (maximum alcohol consumption if free, indexing alcohol value) compared to the breakpoint item (maximum expenditure on a single drink, indexing sensitivity to monetary costs) of the Brief Assessment of Alcohol Demand (BAAD) questionnaire, in student (n = 579) and community (n = 120) drinkers. The community sample showed greater AUD than the student sample (p = .004). In both samples, AUD severity correlated with intensity (students, r = 0.63; community, r = 0.47), but not with breakpoint (students, r = -0.01; community, r = 0.12). Similarly, multiple regression analyses indicated that AUD severity was independently associated with intensity (student, ΔR2 < 0.20, p < .001; community, ΔR2 = 0.09, p = .001) but not breakpoint (student, ΔR2 = 0.003, p = .118; community ΔR2 = 0.01, p = .294). There was no difference between samples in the strength of these associations. The value ascribed to alcohol may play a more important role in AUD severity than discounting of alcohol-associated costs (compulsivity), and there is no apparent difference between student and community drinkers in the contribution of these two mechanisms.

RESUMEN

BACKGROUND: Contingency management (CM), a behavioral intervention that provides incentives for achieving treatment goals, is an evidence-based adjunct to medication to treat opioid use disorder. Unfortunately, many front-line treatment providers do not utilize CM, likely due to contextual barriers that limit effective training and ongoing support for evidence-based practices. This study applied user-informed approaches to adapt a multi-level implementation strategy called the Science to Service Laboratory (SSL) to support CM implementation. METHODS: Leaders and treatment providers working in community-based opioid treatment programs (OTPs; N = 43) completed qualitative interviews inquiring about their preferences for training and support implementation strategies (didactic training, performance feedback, and external facilitation). Our team coded interviews using a reflexive team approach to identify common a priori and emergent themes. RESULTS: Leaders and providers expressed a preference for brief training that included case examples and research data, along with experiential learning strategies. They reported a desire for performance feedback from internal supervisors, patients, and clinical experts. Providers and leaders had mixed feelings about audio-recording sessions but were open to the use of rating sheets to evaluate CM performance. Finally, participants desired both on-call and regularly scheduled external facilitation to support their continued use of CM. CONCLUSIONS: This study provides an exemplar of a user-informed approach to adapt the SSL implementation support strategies for CM scale-up in community OTPs. Study findings highlight the need for user-informed approaches to training, performance feedback, and facilitation to support sustained CM use in this setting.
