Neurocognitive and neurobehavioral mechanisms of change following psychological treatment for alcohol use disorder.

BACKGROUND: Although modestly effective treatments exist for alcohol use disorder (AUD), many individuals return to heavy drinking after treatment, suggesting the need for better understanding of factors that contribute to maintaining abstinence or drinking reductions. Whereas past studies identified what treatments work for AUD, recent studies focus more on why particular treatments work, and the mechanisms by which treatment leads to change. This focus on mechanisms of behavior change (MOBC) may inform the process by which treatment leads to better outcomes, and also may lead to new treatments or modifications of existing treatments that target empirically supported mechanisms known to lead to change. There is a paucity of studies examining MOBC from a neurocognitive perspective. METHOD: To address this gap in knowledge, the study described here is examining emotional reactivity, alcohol cue reactivity, and cognitive control as potential MOBC at three levels of analysis - self-report, behavior, and neural. RESULTS: One hundred ten treatment-seeking individuals with an AUD are being randomized to receive 8 sessions of either Cognitive Behavioral Treatment (CBT) or Mindfulness Based Treatment (MBT) after up to 4 sessions of a platform treatment focused on enhancing motivation to change. To establish the temporal relationship between changes in drinking and changes in MOBC, patients are assessed at baseline, during and immediately after treatment, and 9- and 15-months post-baseline. Relationships between changes in drinking and changes in the proposed MOBC will be examined using advanced mixed modeling techniques. CONCLUSIONS: Results should advance AUD treatment by targeting treatments to neurocognitive MOBC.

Effectiveness and feasibility of a motivational interviewing intake (MII) intervention for increasing client engagement in outpatient addiction treatment: an effectiveness-implementation hybrid design protocol.

BACKGROUND: Client discontinuation from outpatient addiction treatment programs is common, and the initial intake is the service delivery point with the highest attrition rate. Replacing the comprehensive intake assessment with a person-centered Motivational Interviewing (MI) intervention is a potential solution to address provider and client concerns about the disengaging, time-intensive nature of the typical initial intake. It remains unclear whether the use of an alternative to the standard intake at the initial visit can fit within typical organizational reporting requirements, whether it decreases attrition, and whether implementation of person-centered intake procedures within outpatient addiction treatment programs is feasible, acceptable, and can be sustained. PURPOSE: To describe the methods and design of an effectiveness-implementation hybrid type 1 trial of a Motivational Interviewing at Intake (MII) intervention using the Consolidated Framework for Implementation Research (CFIR). METHODS: The study will determine the effectiveness of two intake conditions: (1) standard comprehensive intake assessment (intake-as-usual [IAU]), and (2) MII consisting of a person-centered discussion between provider and client about the client's desire and intent to enter treatment. Although both interventions are focused on understanding client presenting complaints and needs for treatment, the delivery differs as the IAU uses a semi-structured assessment guide, while MII applies the theory of MI to have a conversation about treatment engagement. Adults seeking outpatient addiction treatment services will be randomly assigned to the MII condition (n = 75) or the IAU condition (n = 75). Primary outcomes will be client engagement (i.e., treatment entry, attendance, and completion) obtained from the electronic medical record. Secondary outcomes (client motivation and therapeutic alliance) will be putative mechanisms of client engagement assessed immediately before and after the intake. The trial also will explore determinants of effective, sustainable implementation using assessments of organizational readiness and capacity to change, as well as interviews on MII implementation feasibility. CONCLUSION: This trial of an MII intervention will investigate the feasibility of a motivational intervention as an initial contact with substance use treatment-seeking clients as well as indicators of intervention effectiveness within the systems where it is employed.

A randomized pilot trial of brief family-involved treatment for alcohol use disorder: Treatment engagement and outcomes.

OBJECTIVE: Involving family members in a patient's treatment for alcohol use disorder (AUD) leads to more positive outcomes, but evidence-based family-involved treatments have not been adopted widely in AUD treatment programs. Study aims the following: (a) modify an empirically supported 12-session AUD treatment, alcohol behavioral couple therapy (ABCT) to make it shorter and appropriate for any concerned family member and (b) conduct a small clinical trial to obtain feasibility data and effect size estimates of treatment efficacy. METHOD: ABCT content was adapted to three-sessions following input from clinicians, patients, and family members. Patient and family member dyads were recruited from an inpatient treatment program and randomized to the new treatment, brief family-involved treatment (B-FIT), or treatment-as-usual (TAU). Drinking was assessed using the Form-90; family support and family functioning were assessed using the Family Environment Scale Conflict and Cohesion subscales and the Family Adaptability and Cohesion Evaluation Scale-IV, Communication scale. Dyads (n = 35) were assessed at baseline and 4-month follow-up. RESULTS: On average, dyads received one of three B-FIT sessions with 6 dyads receiving no sessions due to scheduling conflicts or patient discharge. At follow-up, there was a large-to-medium effect size estimate favoring B-FIT for proportion drinking days (patient report, n = 22; Hedges' g = 1.01; patient or family report, n = 28; Hedges' g = .48). Results for family support or family functioning measures favored TAU. CONCLUSIONS: Implementation of brief family-involved treatment in inpatient AUD treatment was challenging, but preliminary data suggest the potential value of B-FIT in impacting drinking outcomes.

A clinical science guide for reviewing the cross-cultural rigor of assessments in an alcohol training clinic.

A standard component of service delivery in alcohol treatment clinics is evidence-based assessment (EBA). Although EBA is essential for selecting appropriate treatment modalities for alcohol use and associated problems, there are limitations in existing EBAs concerning evidence of cultural equivalence and utility among individuals seeking alcohol treatment. However, training in EBA, addictions, and clinical applications with diverse populations all are gaps in clinical training in doctoral programs in clinical psychology. The present work used the clinical science model to review the psychometric properties, cross-cultural utility, and measurement invariance of measures in an assessment battery used in an alcohol treatment training clinic. This article describes the results of that review, recommendations for retaining or replacing common assessment measures used in alcohol treatment clinics, and recommendations for alcohol treatment clinics interested in engaging in similar processes. Findings suggested that more research is needed to evaluate the psychometric properties of EBAs utilized in an alcohol treatment assessment battery, particularly among American Indian and Alaska Native people, and to test measurement invariance across race/ethnicity and other identity groups in alcohol treatment-seeking populations. Overall, routine reviews of cultural relevance are needed in clinical settings to stay current with the emerging literature. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Optimizing the length and reliability of measures of mechanisms of change to support measurement-based care in alcohol use disorder treatment.

OBJECTIVE: Clients who receive alcohol use disorder (AUD) treatment experience variable outcomes. Measuring clinical progress during treatment using standardized measures (i.e., measurement-based care) can help indicate whether clinical improvements are occurring. Measures of mechanisms of behavioral change (MOBCs) may be particularly well-suited for measurement-based care; however, measuring MOBCs would be more feasible and informative if measures were briefer and if their ability to detect reliable change with individual clients was better articulated. METHOD: Three abbreviated measures of hypothesized MOBCs (abstinence self-efficacy, coping strategies, anxiety) and a fourth full-length measure (depression) were administered weekly during a 12-week randomized trial of cognitive-behavioral therapy (CBT) for women with AUD. Psychometric analyses estimated how reliably each measure distinguished within-person change from between-person differences and measurement error. Reliability coefficients were estimated for simulated briefer versions of each instrument (i.e., instruments with fewer items than the already-abbreviated instruments) and rates of reliable improvement and reliable worsening were estimated for each measure. RESULTS: All four measures had good reliability (.86-.90) for detecting within-person change. Many participants (41.4%-62.5%) reliably improved on MOBCs from first to last treatment session. Reliable improvement on MOBCs was associated with reductions in percentage of drinking days (PDD) at 3, 9, and 15-month follow-ups. Simulated briefer versions of each instrument retained good reliability for detecting change with only 3 (self-efficacy), 11 (coping strategies), 5 (anxiety), or 10 items (depression). CONCLUSIONS: Brief MOBC measures can detect reliable change for individuals in AUD treatment. Routinely measuring MOBCs may help with monitoring clinical progress.

The Role of the Family in Alcohol Use Disorder Recovery for Adults.

Alcohol use disorder (AUD) and family functioning are inextricably bound, and families are impacted negatively by AUD, but families show substantial improvements with AUD recovery. Family members can successfully motivate a person with AUD to initiate changes in drinking or to seek AUD treatment. During recovery, family members can provide active support for recovery. Several couple- or family-involved treatments for AUD have been developed and tested in rigorous efficacy trials. Efficacious treatments based in family systems theory or cognitive behavioral approaches focus on the concerned family member alone, or they engage the couple or family as a unit in the treatment. However, most treatments have been studied in fairly homogeneous, heterosexual, White, non-Hispanic populations, limiting the potential generalizability of these treatments. Substantial gaps remain in our understanding of family processes associated with the initiation and maintenance of AUD recovery among adults. This review outlines the existing literature and describes opportunities for future research to address knowledge gaps in understanding the mechanisms by which these treatments are efficacious, use of family-based treatments with diverse populations, integration of pharmacotherapies with family-involved treatment, role of families in recovery-oriented systems of care, and how to improve treatment development and dissemination.

Do alcohol interventions affect peers who do not receive the intervention? Modeling treatment contagion effects via simulations of adolescent social networks.

OBJECTIVE: Adolescents' drinking is influenced by their friends' drinking. However, it is unclear whether individually-targeted alcohol interventions reduce drinking in the friends of individuals who receive the intervention. This study used simulations of drinking in simulated longitudinal social networks to test whether individually-targeted alcohol interventions may be expected to spread to non-targeted individuals. METHOD: Stochastic actor-based models simulated longitudinal social networks where changes in drinking and friendships were modeled using parameters from a meta-analysis of high school 10th grade social networks. Social influence (i.e., how much one's friends' drinking affects their own drinking) and social selection (i.e., how much one's drinking affects who they select as friends) were manipulated at several levels. At the midpoint of each simulation, a randomly-selected heavy-drinking individual was experimentally assigned to an intervention (changing their drinking status to non-drinking) or a control condition (no change in drinking status) and the drinking statuses of that individual's friends were recorded at the end of the simulation. RESULTS: Friends of individuals who received the intervention significantly reduced their drinking, with higher reductions occurring in networks with greater social influence. However, all effect sizes were small (e.g., average per-friend reduction of .07 on a 5-point drinking scale). CONCLUSIONS: Individually-targeted alcohol interventions may have small effects on reducing the drinking of non-targeted adolescents, with social influence being a mechanism that drives such effects. Due to small effect sizes, many adolescents may need to receive alcohol interventions to produce measurable effects on drinking outcomes for non-targeted individuals.

Aligning three substance use disorder interventions among a tribe in the Southwest United States: Pilot feasibility for cultural re-centering, dissemination, and implementation.

In this article we describe cultural re-centering, dissemination, and implementation activities in partnership between an American Indian reservation community and a university in the Southwest United States. We offer examples of cultural adaptation and implementation of evidence-based treatments (e.g., Motivational Interviewing, Community Reinforcement Approach and the Community Reinforcement and Family Training) using the Interactive Systems Framework. Facilitators and barriers are described within each study including recruitment strategies, training, and sustainability of counselors in the community. Through this Tribal-university partnership, we offer insight on the cultural adaptation and implementation process that will be translatable and clinically meaningful to other rural and reservation communities.

The Indirect Relationship Between Interpersonal Trauma History and Alcohol Use via Negative Cognitions in a Multisite Alcohol Treatment Sample.

Although interpersonal trauma history (ITH) is frequently associated with alcohol use disorder (AUD), little is known about specific psychological constructs that may indirectly link these phenomena. This study hypothesized that one such construct may be negative cognitive schemas that often emerge in the aftermath of trauma. Secondary latent variable modeling was conducted using the Project MATCH sample of adults receiving treatment for AUD (N = 1726; 24.3% women; 38.63% ITH). The negative cognitions latent variable provided an excellent fit to the data and showed evidence of strong measurement invariance. As hypothesized, negative cognitions mediated the inverse association between ITH at baseline and percent days abstinent from alcohol 12 weeks later. Findings suggest that negative cognitions may be a specific underlying mechanism and potential treatment target for individuals with ITH and AUD.

Inside Alcohol Behavioral Couple Therapy (ABCT): In-session speech trajectories and drinking outcomes.

The alcohol treatment literature has established in-session client speech as a mechanism of change that therapist behavior can influence and that can predict drinking outcomes. This study aimed to explore temporal patterns of in-session speech in Alcohol Behavioral Couple Therapy (ABCT), including the unique interplay between client and partner speech and the role of speech trajectories in predicting client drinking outcomes. Participants were 165 heterosexual couples receiving ABCT in one of four clinical trials. We coded client speech on an utterance-by-utterance basis using the System for Coding Couples' Interactions in Therapy-Alcohol. We focused on individual-level speech codes of change talk and sustain talk and couple-level variables of positive and negative interactions. We segmented the initial and midtreatment sessions into quartiles to conduct path analyses and latent growth curve models. Path analyses suggested that clients and partners may not have been aligned in terms of treatment goals at the start of the therapy. This misalignment within couples was pronounced during the initial session and decreased by the midtreatment session, reflecting progression toward treatment goals. Of the latent growth curve models, only client sustain talk during the midtreatment session predicted greater client drinking at the end of treatment. Results provide insight into the inner workings of ABCT and suggest recommendations for ABCT therapists. This study also supports a growing consensus that sustain talk may be a stronger mechanism of change than change talk in various alcohol treatment interventions.

Treatment Interventions for Women With Alcohol Use Disorder.

Women with alcohol use disorder (AUD) experience more barriers to AUD treatment and are less likely to access treatment than men with AUD. A literature review identified several barriers to women seeking help: low perception of a need for treatment; guilt and shame; co-occurring disorders; employment, economic, and health insurance disparities; childcare responsibilities; and fear of child protective services. Women entering treatment present with more severe AUD and more complex psychological, social, and service needs than men. Treatment program elements that may reduce barriers to AUD treatment include provision of childcare, prenatal care, treatment for co-occurring psychological problems, and supplemental social services. Research has suggested that outcomes for women are best when treatment is provided in women-only programs that include female-specific content. To date, research on treatments tailored to the individual needs of women is limited, but research on mechanisms of change has suggested the importance of targeting anxiety and depression, affiliative statements in treatment, abstinence self-efficacy, coping skills, autonomy, and social support for abstinence. Future research should focus on early interventions, linkages between primary care or mental health clinics and AUD treatment settings, and integrated treatments for co-occurring AUD and other disorders. Further research should also explore novel treatment delivery approaches such as digital platforms and peer support groups.

A randomized comparison of extended-release naltrexone with or without patient navigation vs enhanced treatment-as-usual for incarcerated adults with opioid use disorder.

The high prevalence of opioid use among justice-involved adults make jails an exceptional setting to initiate opioid use disorder (OUD) treatment, but optimal strategies for delivering these interventions are still not well understood. The objective of this study was to conduct a randomized controlled trial to assess the effectiveness of extended-release naltrexone (XR-NTX, Vivitrol®; Alkermes Inc) alone or in conjunction with patient navigation (XR-NTX + PN) for jail inmates with OUD. We randomized a sample of 135 sentenced jail inmates with moderate to severe OUD to (1) XR-NTX only; (2) XR-NTX + PN; or (3) enhanced treatment-as-usual (ETAU) with drug education, each initiated prior to release from jail. We scheduled follow-up data assessments at 1, 3, 6, and 12 months post-release. Primary outcomes were opioid use (based on Timeline Followback Interview and Addiction Severity Index) and meeting CIDI DSM-5 criteria for OUD 6 months postrelease. We also measured treatment adherence, HIV risk, and recidivism. XR-NTX participants received a mean of 2.26 of 7 possible injections compared to XR-NTX + PN participants, who received a mean of 2.93 injections (Cohen's d = 0.33, 95% CI: -0.09 to 0.74). Thirty-six percent of patients in XR-NTX + PN attended at least one postrelease PN session. We found no significant differences by study condition six months after release from jail for the primary outcomes of any opioid use (ETAU: 17%, XR-NTX: 16%, XR-NTX + PN: 29%) and past 30-day OUD (ETAU: 8%, XR-NTX: 11%, XR-NTX + PN: 10%). Secondary outcomes of rearrest and HIV risk also were similar across groups, with the exception of lower sex-related HIV risk among those in the XR-NTX condition at 12 months. This study did not show superior outcomes of XR-NTX or XR-NTX + PN with regard to opioid use or recidivism outcomes, relative to ETAU. It did, however, highlight the difficulties with adherence to XR-NTX and PN interventions in OUD patients initiating treatment in jail.

Cost-effectiveness analysis of a large jail-based methadone maintenance treatment continuation program in New Mexico.

The U.S. has the second-highest incarceration rate in the world and spends more than $80 billion annually to house inmates. The clinical research literature suggests that methadone maintenance treatment (MMT) is an effective method to treat opioid use disorders (OUD) and that jails are a potentially valuable environment to implement MMT. Currently, jail-based MMT is rarely implemented in practice, due in part to resource limitations and other economic considerations. The primary goal of this study was to perform a cost-effectiveness analysis (CEA) of jail-based MMT using data from a unique MMT continuation program located in a large urban jail in New Mexico. Recidivism data were collected for a three-year period both before and after incarceration, and quasi-control groups were constructed from both substance-using and general populations within the jail. Base models show that inmates enrolled in jail-based MMT exhibited significantly fewer days of incarceration due to recidivism (29.33) than a group of inmates with OUDs who did not receive MMT. Economic estimates indicate that it cost significantly less ($23.49) to reduce an incarcerated day using jail-based MMT than incarceration per se ($116.49). To mitigate potential sample selection bias, we used both propensity-score-matching and difference-in-differences estimators, which provided comparable estimates when using the OUD non-MMT comparison group. Difference-in-differences models find that, on average, MMT reduced recidivism by 24.80 days and it cost $27.78 to reduce an incarcerated day using jail-based MMT. Assuming a willingness to pay threshold of the break-even cost of reducing one incarcerated day, we estimate a 93.3% probability that this MMT program is cost-effective. Results were not as strong or consistent when using other comparison groups (e.g., alcohol-detoxified and general-population inmates). Overall, results suggest that it costs substantially less to provide jail-based MMT than incarceration alone. Jail administrators and policymakers should consider incorporating MMT in other jail systems and settings.

Menstrual cycle phase, alcohol consumption, alcohol cravings, and mood among women in outpatient treatment for alcohol use disorder.

Research shows fluctuations in drinking across the menstrual cycle among women with alcohol use disorder (AUD), but little work has investigated moderators of these fluctuations. This study examined drinking and craving intensity across the menstrual cycle, and the moderating effect of baseline depression and emotional distress during the midlate luteal phase and/or menses, among women receiving AUD treatment. Fifty-nine regularly cycling women reported menstrual history and baseline depression. Over 3 months of treatment, they kept daily logs of drinks, alcohol cravings, and menstruation (yes/no). Emotional distress during the midlate luteal phase and/or menses of their most recent menstrual cycle was also assessed during treatment. Menstrual cycle phase was estimated for each within-treatment day. Mixed model analyses tested main and interactive effects of menstrual cycle phase, baseline depression, and emotional distress during the midlate luteal phase and/or menses on daily drinks and craving intensity. Women drank most during the midlate luteal phase and menses compared with other phases. Among women with lower baseline depression, those with lower distress during the midlate luteal phase and/or menses reported more intense cravings during the midlate luteal phase (ΔM = .77, p = .000) and menses (ΔM = .51, p = .012); those with higher distress reported more intense cravings during menses, compared with all other phases (p < .01). Among women with higher baseline depression, craving intensity remained consistently high. Results document more drinking during the midlate luteal phase and menses and suggest that cycle-related distress and depression moderate the alcohol-menstrual association among women in AUD treatment.

Mechanisms of change in female-specific and gender-neutral cognitive behavioral therapy for women with alcohol use disorder.

OBJECTIVE: In a randomized trial for women with alcohol use disorders (AUD), the efficacy of Female-Specific Cognitive Behavioral Therapy (FS-CBT) was compared with Gender-Neutral CBT (GN-CBT; Epstein et al., 2018). The current study examined whether putative mechanisms of change differed between treatment conditions, using a novel statistical approach. Both treatments were hypothesized to work by increasing use of alcohol-related coping skills (coping) and confidence to abstain from drinking (confidence), but FS-CBT additionally targeted female-salient mechanisms: anxiety, depression, sociotropy (i.e., overinvestment in others' opinion of oneself), autonomy, and social networks supportive of abstinence. METHOD: Ninety-nine women with AUD (55 in GN-CBT, 44 in FS-CBT) completed self-report assessments at baseline and 0, 6, and 12 months posttreatment. Multilevel vector autoregression estimation was used to analyze associations between putative mechanisms of change, and network models of those associations were generated using network analysis. RESULTS: Across conditions, higher confidence and coping were directly associated with less drinking; autonomy was directly and indirectly associated with drinking. Additionally, network analysis indicated that although variation in depression was associated with change in other variables specifically for GN-CBT, sociotropy was associated with change specifically in FS-CBT. CONCLUSIONS: Women receiving CBT-AUD changed their drinking through increased confidence to abstain and greater use of coping skills. Autonomy played a central role in behavior change across treatment conditions. Participants receiving treatment tailored to women also changed through decreases in sociotropy and increases in social support for abstinence. For women who received standard CBT, changes in depression were important to clinical improvement. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Education and Training in Substance Use Disorders and Addictions: The University of New Mexico Integrated Training Model.

This paper describes SUD/addictions training at the University of New Mexico. Coordinated and integrated academic, research, and clinical training resources are described, with an emphasis on the integration of resources across multiple training domains. Academic training resources in the Psychology Department include core clinical courses, basic science courses, and opportunities for students to develop expertise in health or quantitative psychology. Other academic resources come from affiliated departments and colleges such as Sociology, the College of Population Health, the College of Education, and Health Sciences. Research training resources are available within the Psychology Department, affiliated Departments and Colleges, and specialized research centers including the Center on Alcoholism, Substance Abuse, and Addictions, and the Mind Research Network. A network of community partners provides additional research sites. Clinical training resources are provided through a specialized alcohol treatment clinic and a diversity clinic within the Department, opportunities for students to serve as research clinicians, and community practicum sites supervised by on-site doctoral level psychologists or Departmental faculty. The UNM training program provides one model for graduate training in SUD/addictions. Keys to the program are the presence of multiple SUD/addictions clinical faculty member with active research programs, willingness to mentor students in research and clinical work, and basic science faculty whose research is relevant to addictive behaviors. Other critical elements include systematic development of clinical training opportunities, effective collaborations with community agencies for research and clinical training, meaningful research partnerships with other academic departments and specialized research centers, and external funding for training activities.

Smoking characteristics and alcohol use among women in treatment for alcohol use disorder.

BACKGROUND: Understanding the association between smoking and alcohol use among women may help inform the delivery of targeted interventions to address both of these health behaviors. METHODS: This study analyzed data from N = 138 women enrolled in a randomized clinical trial comparing female-specific individual versus group cognitive-behavior therapy for alcohol use disorder (AUD). We assessed cigarette use patterns, participants' interest in quitting smoking and motivation to quit smoking during treatment for AUD, and examined the relationship between smoking and alcohol use before and during alcohol treatment. RESULTS: Over a third of the sample reported smoking cigarettes at baseline (N = 47, 34.1%), with the majority of smokers reporting daily cigarette use. At baseline, those who smoked reported a high interest in quitting smoking M = 7.8 out of 10 (SD = 2.7), although most believed they should quit smoking only after achieving some success in quitting drinking (50.0%). However, participants who smoked cigarettes (compared to non-smokers) reported more alcohol abuse and dependence symptoms (p = .001), lower rates of completing the alcohol treatment (p = .03), attended significantly fewer treatment sessions (p = .008), and consumed significantly more drinks per day on average both at baseline (p = .002) and during the treatment period (p = .04). CONCLUSIONS: Findings suggest that women with AUD who also smoke cigarettes have greater difficulty engaging in or responding to treatment for their alcohol use. However, these participants reported high interest in quitting smoking but low perceived readiness during AUD treatment, suggesting that motivational interventions should be considered that could take advantage of the opportunity to treat women for both of these co-occurring behaviors while in treatment.

Changes in Hypothesized Mechanisms of Change Before and After Initiating Abstinence in Cognitive-Behavioral Therapy for Women With Alcohol Use Disorder.

Abstinence self-efficacy, coping skills, and therapeutic alliance are hypothesized mechanisms of behavioral change (MOBCs) in cognitive-behavioral therapy (CBT) for alcohol use disorder (AUD). However, little is known about when these hypothesized MOBCs change during treatment or in relation to the initiation of abstinence from alcohol, which the current study investigated. Patient-reported abstinence self-efficacy, drinking-related coping skills, and therapeutic alliance were measured at every session throughout a 12-session clinical trial that previously showed equivalent drinking reductions in female-specific individual- and group-based CBT for AUD. Participants (N = 121 women) were classified into subgroups based on whether and when they first initiated 14 days of continuous abstinence from alcohol during treatment. Interrupted time-series analyses evaluated the magnitude and timing of change in MOBC variables in relation to the initiation of abstinence. All three MOBC measures showed gradual improvements throughout treatment (within-subjects d = 0.03 to 0.09 change per week). Participants who initiated abstinence during treatment experienced additional sudden improvements in abstinence self-efficacy (d = 0.47) and coping skills (d = 0.27), but not therapeutic alliance (d = -0.02), the same week they initiated abstinence. Participants who were already abstinent when treatment started maintained higher abstinence self-efficacy and coping skills, but not therapeutic alliance, throughout treatment compared to participants who never initiated abstinence. Initiating abstinence may help facilitate improvements in abstinence self-efficacy and drinking-related coping skills. Clinicians may help patients anticipate when and how much these variables are expected to improve during treatment and encourage initiation of abstinence to potentially help facilitate improvements in abstinence self-efficacy and coping skills.

Design of a randomized controlled trial examining the efficacy of oxytocin to enhance alcohol behavioral couple therapy.

Combining pharmacological interventions with evidence-based behavioral interventions may help optimize treatment outcomes for alcohol use disorder (AUD). While several effective behavioral interventions for AUD have been developed, the vast majority target individual patients, despite evidence that behavioral interventions for couples have the ability to outperform individual treatments for AUD. Alcohol Behavioral Couples Therapy (ABCT) is an evidence-based behavioral intervention for couples that has been shown to significantly reduce AUD severity as well as improve relationship functioning. Accumulating evidence suggests that the neuropeptide oxytocin has the ability to reduce alcohol craving and consumption, symptoms of tolerance and withdrawal, and ameliorate neurobiological deficits associated with AUD. Furthermore, oxytocin has demonstrated the ability to increase prosocial behavior and cognition, and restore sensitivity to natural rewards such as interpersonal relationships. No study to date has examined the ability of oxytocin to enhance ABCT. Thus, the primary objective of this Phase II study is to examine the effects of oxytocin versus placebo in combination with ABCT in reducing AUD severity and improving relationship functioning. We also will utilize neuroimaging techniques before and after treatment to investigate the underlying pathophysiology of AUD among couples and identify prognostic indicators of treatment outcome. The findings from this study might provide critical new information to help inform clinical practice and accelerate research on the pharmacological treatment of AUD.

Cost-effectiveness of individual versus group female-specific cognitive behavioral therapy for alcohol use disorder.

OBJECTIVE: To determine the relative cost-effectiveness of individual female-specific cognitive behavioral therapy (I-FS-CBT) versus group female-specific cognitive behavioral therapy (G-FS-CBT). METHODS: This cost-effectiveness study is based on a randomized controlled trial in which 155 women seeking treatment for alcohol use disorder at an academic outpatient clinic were randomized to 12 manual-guided sessions of I-FS-CBT (n = 75) or G-FS-CBT (n = 80). The primary patient outcomes were the number of drinking days and the number of heavy drinking days during the 12-week treatment and 1-year follow-up periods. All cost data (including resource utilizations) were collected prospectively alongside the trial. Incremental cost-effectiveness ratios and cost-effectiveness acceptability curves were used to determine the cost-effectiveness of I-FS-CBT relative to G-FS-CBT. Results are presented from the provider perspective. RESULTS: During the 12-week treatment period, G-FS-CBT is likely to be cost-effective when the threshold value to decision-makers of one fewer drinking day (or one fewer day of heavy drinking) is less than $141 (or $258), and I-FS-CBT is likely to be cost-effective if the threshold is greater than $141 (or $258). During the 1-year follow-up period, G-FS-CBT is likely to be cost-effective when the threshold value to decision-makers of one fewer drinking day (or one fewer day of heavy drinking) is less than $54 (or $169), and I-FS-CBT is likely to be cost-effective if the threshold is greater than $54 (or $169). The results are robust to sensitivity analyses on several key cost parameters. CONCLUSIONS: Compared to I-FS-CBT, G-FS-CBT holds promise as a cost-effective approach, in both the short run and the long run, for improving drinking outcomes of women with alcohol use disorder.
