Psychometric properties of the system for coding couples' interactions in therapy--alcohol

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.

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.

Alcohol Behavioral Couple Therapy: In-session behavior, active ingredients and mechanisms of behavior change

OBJECTIVE

Alcohol Behavioral Couple Therapy (ABCT) is an efficacious alcohol treatment. The purpose of the study was to describe patient and partner language and therapist behavior during therapy sessions and test a proposed causal model linking active ingredients of ABCT as measured by therapist behaviors, hypothesized mechanisms of behavior change as measured by in-session patient and partner language, and alcohol use outcomes.

METHOD

Data came from couples in four ABCT clinical trials (N = 188; 86 males, 102 females, and their partners). Patient and partner verbal behaviors in session one and a mid-treatment session were coded using the System for Coding Couples' Interactions in Therapy-Alcohol. Therapist behavior was coded using the Couples Treatment Integrity Rating System. Percent days abstinent was calculated from daily drinking data for the first and second half of treatment and six months post-treatment.

RESULTS

Therapists delivered an adequate level of the ABCT interventions during treatment. During treatment, couples increased positive behaviors, talked less about drinking, and decreased their amount of motivational language. Therapist behaviors did not predict patient or partner behaviors during treatment or drinking outcomes. Partner advice in the first session predicted poorer drinking outcomes. At mid-treatment, patient behaviors as a block, and specific behaviors of contemptuousness toward their partner and sustain talk, predicted poorer drinking outcomes.

CONCLUSIONS

During ABCT, patients decrease their drinking, and patient and partner behaviors change in predicted ways. Partner advice, patient contemptuousness, and patient sustain talk predicted poorer outcomes. Analyses of within-session verbal behavior did not support the hypothesized mechanisms for change for ABCT.

Alcohol-Focused Behavioral Couple Therapy

Alcohol Behavioral Couple Therapy (ABCT) has emerged over the last 30 years as a highly efficacious treatment for those with alcohol use disorders. This review highlights the historical and conceptual underpinnings of ABCT, as well as the specific treatment elements and structure. Proposed active ingredients, moderators, and mediators of treatment outcome are discussed. Efficacy is evaluated for reductions in identified patient drinking, improved relationship functioning, and reductions in intimate partner violence. Adaptations of ABCT for substances other than alcohol are described. Other adaptations, including brief interventions, interventions addressing PTSD and TBI along with alcohol use, and interventions deliverable via technology platforms are described. Additional cost-benefit and cost-effectiveness findings supporting the economic value of ABCT are noted. Future directions for research in this area include possible adaptations for female identified patients, nontraditional couples, LGBT partners and dyads involving nonintimate partner relationships. The development of more flexible models and enhanced dissemination strategies may improve clinical uptake and utility as well as increasing the feasibility of this treatment for integrated healthcare settings.

The Alcohol Intervention Mechanisms Scale (AIMS): Preliminary Reliability and Validity of a Common Factor Observational Rating Measure

The present work provides an overview, and pilot reliability and validity for the Alcohol Intervention Mechanisms Scale (AIMS). The AIMS measures therapist interventions that occur broadly across modalities of behavioral treatment for alcohol use disorder. It was developed based on identified commonalities in the function rather than content of therapist interventions in observed therapy sessions, as well as from existing observer rating systems. In the AIMS, the primary function areas are: explore (four behavior count codes), teach (five behavior count codes), and connect (three behavior count codes). Therapist behavior counts provide a frequency rating of occurrence (i.e., adherence). The three functions (explore, teach, connect) are then rated on global skillfulness, which provides a quality valence (i.e., competence) to the entire session. In the present study, three independent raters received roughly 30 hours of training on the use of the AIMS by the first author. Data were a sample of therapy session audio files from a Project MATCH clinical research site. Reliability results showed generally good performance for the measure. Specifically, 2-way mixed intraclass coefficients were 'excellent', ranging from .94 to .99 for function summary scores, while prevalence-adjusted, bias-adjusted kappa for global skillfulness measures were in the 'fair' to 'moderate' range (k=.36 to.40). Internal consistency reliability was acceptable, as were preliminary factor models by behavioral treatment function (i.e., explore, teach, connect). However, confirmatory fit for the subsequent three factor model was poor. In concurrent validity analyses, AIMS summary and skillfulness scores showed associations with relevant Project MATCH criterion measures (i.e., MATCH Tape Rating Scale) that were consistent with expectations. The AIMS is a promising and reliable observational measure of three proposed common functions of behavioral alcohol treatment.

Typology of Couples Entering Alcohol Behavioral Couple Therapy: An Empirical Approach and Test of Predictive Validity on Treatment Response

This study aimed to examine whether classification of couples in which one partner has an alcohol problem is similar to that reported in the general couples literature. Typologies of couples seeking alcohol behavioral couple therapy (ABCT) were developed via hierarchical cluster analysis using behavioral codes of couple interactions during their first ABCT session. Four couples types based on in-session behavior were established reliably, labeled avoider, validator, hostile, and ambivalent-detached. These couple types resembled couples types found in previous research. Couple type was associated with baseline relationship satisfaction, but not alcohol use. Results suggest heterogeneity in couples with alcohol problems presenting to treatment; further study is needed to investigate the function of alcohol within these different types.

Active Ingredients of Treatment and Client Mechanisms of Change in Behavioral Treatments for Alcohol Use Disorders: Progress 10 Years Later

BACKGROUND

The current review revisits the article entitled: "Active Ingredients: How and Why Evidence-Based Alcohol Behavioral Treatment Interventions Work" published in Alcoholism: Clinical and Experimental Research. This work summarized proceedings from a 2004 Symposium of the same name that was held at the Annual Meeting of the Research Society on Alcoholism (RSA). A decade has passed, which provides occasion for an evaluation of progress. In 2014, an RSA symposium titled Active Treatment Ingredients and Client Mechanisms of Change in Behavioral Treatments for Alcohol Use Disorders: Progress 10 Years Later did just that.

METHODS

The current review revisits state-of-the-art research on the 3 treatments examined 10 years ago: cognitive behavioral therapy, alcohol behavior couples therapy, and 12-step facilitation. Because of its empirically validated effectiveness and robust research agenda on the study of process outcome, motivational interviewing has been selected as the fourth treatment modality to be discussed. For each of these 4 treatments, the reviewers provide a critical assessment of current theory and research with a special emphasis on key recommendations for the future.

RESULTS

Noteworthy progress has been made in identifying active ingredients of treatments and mechanisms of behavior change in these 4 behavioral interventions for alcohol and other drug use disorders. Not only have we established some of the mechanisms through which these evidence-based treatments work, but we have also uncovered some of the limitations in our existing frameworks and methods.

CONCLUSIONS

Further progress in this area will require a broader view with respect to conceptual frameworks, analytic methods, and measurement instrumentation.
