A randomized controlled trial to influence client language in substance use disorder treatment

The evolution of motivational interviewing

This review traces the development of motivational interviewing (MI) from its happenstance beginnings and the first description published in this journal in 1983, to its continuing evolution as a method that is now in widespread practice in many professions, nations and languages. The efficacy of MI has been documented in hundreds of controlled clinical trials, and extensive process research sheds light on why and how it works. Developing proficiency in MI is facilitated by feedback and coaching based on observed practice after initial training. The author reflects on parallels between MI core processes and the characteristics found in 70 years of psychotherapy research to distinguish more effective therapists. This suggests that MI offers an evidence-based therapeutic style for delivering other treatments more effectively. The most common use of MI now is indeed in combination with other treatment methods such as cognitive behaviour therapies.

The role of the relational context and therapists' technical behaviors in brief motivational interviewing sessions for heavy alcohol consumption: Findings from a sample of Latinx adults

INTRODUCTION

Motivational interviewing (MI) theory and process research highlights the role of therapist technical and relational behaviors in predicting client in-session statements for or against behavior change (i.e., change and sustain talk, respectively). These client statements, in turn, have been shown to predict intervention outcomes. The current study examines sequential associations between therapist behaviors and client change and sustain talk in a sample of Latinx individuals who engage in heavy alcohol consumption.

DATA

Data are from a completed randomized clinical trial of a culturally adapted (CAMI) versus unadapted MI targeting alcohol use and consequences among Latinx individuals.

METHOD

The study collected observational coding data with the Motivational Interviewing Skill Code (MISC 2.5, i.e., therapist behaviors and global ratings) and the Client Language Assessment - Proximal/Distal (CLA-PD, i.e., client language). Frequentist and Bayesian sequential analyses examined the relationship among nine different categories of therapist behaviors and three different categories of client language (i.e., change talk, sustain talk, neutral). We examined odds ratios and conditional probabilities for the direction, magnitude, and significance of the association between the use of MI technical behaviors and subsequent client statements about change. The study compared these same transitional associations between low/average (i.e., <4) and high (i.e., ≥4) MI Spirit sessions.

RESULTS

The pattern of results was replicated across both analytic frameworks. Questions and reflections about change talk versus sustain talk versus neutral statements showed greater odds of predicting the intended client response (i.e., change talk, sustain talk, neutral, respectively) compared to other possible client responses. Conditional probabilities for these transitions were high, ranging from 0.55 to.88. The magnitude of certain technical transitions significantly differed between low/average and high MI Spirit sessions.

CONCLUSIONS

Analyses supported the hypothesized associations between therapist use of technical MI behaviors and client change language within this Latinx sample. Analyses of MI Spirit as a moderator of these transitions showed partial support.

Should Substance Use Counselors Choose a Direction For Their Clients? Motivational Interviewing Trainers May Be Ambivalent

Motivational Interviewing (MI) is comprised of a client-centered relationship and a clear intention on the part of the practitioner to influence behavior change. This study explores MI trainers' decisions about their use of directionality in MI as they instruct others in the method. 111 MI trainers were asked to select content they would include in a hypothetical MI training. Almost half of trainers chose to teach trainees to "always maintain an attitude of equipoise", a strategy that is contradicted by MI theory and empirical data. This finding suggests a theoretical rift within the MI community with implications for substance use counseling.

Can a pure motivational interviewing intervention be manualized and still efficacious? A test of feasibility and initial efficacy

The importance of attending to the therapeutic process despite the challenges in manualizing it is demonstrated in the empirical evolution of motivational interviewing (MI). Whereas manuals exist for adaptations of MI, no manual has been developed and tested for MI in its pure form (pure MI). This study evaluated the feasibility and initial efficacy of a pure MI intervention manual - MI for risky social drinking (MI-RSD) - designed to target risky social drinking behaviors in college students with social anxiety. A pilot sample of 42 college students completed measures of alcohol use and mental health symptoms and the MI-RSD intervention. We developed a manual for the 2-session MI-RSD intervention, trained 4 clinical doctoral students, and used observer-, therapist- and participant-completed measures to evaluate fidelity. Therapists met beginner proficiency in MI fidelity and participant gave high ratings of therapist adherence to MI and working alliance, demonstrating intervention feasibility. Also, participants reported significant reductions in hazardous drinking and evaluation fears, but not in social interaction anxiety. We offer preliminary evidence that pure MI can be manualized and effective. Specifically, MI-RSD represents an alternative to MI adaptations in mitigating alcohol-related harm for young adults.

Integration of motivational interviewing and behavioral economic theories to enhance brief alcohol interventions: Rationale and preliminary examination of client language

Motivational interviewing (MI) is a widely disseminated evidence-based therapeutic approach for engaging clients and motivating health behavior change, especially risky substance use. Refinement of MI theory over the past few decades has provided empirical evidence that the technical component of MI (in-session client language) is a promising mechanism of behavior change (MOBC). However, heterogeneous and small to moderate effect sizes suggest the need for refinement of MOBC measurement and consideration of other types of client language. The current article presents a complementary integration of current MI theory and behavioral economic (BE) mechanisms to further understanding of in-session factors associated with subsequent behavior change. In this paper, we define some of the key MOBCs from MI and BE theories, describe our integrated framework, and present preliminary findings from a pilot study of the effectiveness and MOBCs of a novel BE-informed application of MI in risky college student drinkers. Results from preliminary coding development suggest that BE-informed measures of client language better predict response to a brief intervention in risky college students than traditional change talk measures. We posit that BE theory can offer insight into meaningful session content beyond the current MI constructs of change talk and sustain talk, which in turn may serve to enhance development of clinical practice and inform scientific investigations.

Mechanisms of Motivational Interviewing: a Conceptual Framework to Guide Practice and Research

Reviews of the motivational interviewing (MI) training literature demonstrate MI is a nuanced skill set that takes carefully planned didactic training, application of skills in context-specific practice settings, and ongoing support to promote reflective practice and sustained proficiency. Despite the robust knowledge base related to training and how MI works to achieve favorable outcomes, these two literature bases are not well integrated. In an effort to inform and guide future research, we propose the mechanisms of motivational interviewing (MMI) conceptual framework, which expands upon previous work. Specifically, the framework adds training as an ongoing process consistent with Bennett-Levy's (Behav Cogn Psychother 34:57-78, 2006) model of skill development and acquisition to the existing two-path framework that helps us to understand how MI works to achieve its desired effects (Magill et al., J Consult Clin Psychol 82:973-983, 2014). Herein, we describe measures used to evaluate the mechanisms within the four MMI framework links: initial training to competency, competency to proficiency, proficiency to talk about change, and talk about change to behavior change. Next, we synthesize the literature associated with each of the mechanisms of the MMI. We conclude by discussing implications for practice and research. This framework offers a more complete path structure to understand the mechanisms of change associated with MI that could improve our understanding of inconsistent effect sizes observed across prior trials evaluating MI effectiveness.

Examining the influence of active ingredients of motivational interviewing on client change talk

Motivational Interviewing (MI) is an evidenced-based intervention designed to help clients explore and resolve ambivalence around substance use. MI combines a humanistic tradition with behavioral components to facilitate client decisions concerning behavior change. As such, there is marked interest in the relationship between the two active ingredients of MI - the relational, or person-centered, components and the technical, or directional, behavioral components - on client in-session language. Yet, few studies have examined how these active ingredients operate in concert. Therefore, the current study evaluated the constellation of relational skills associated with client language, as well as the influence of technical skills on the relationship between provider relational skills and client change language. Specifically, we tested a latent construct of relational skill and its direct association with the proportion of client change talk. We then explored the mediating role of reflections of change and sustain talk (RefCT and RefST) on this relationship. The data for this secondary analysis are from Project ELICIT (N = 131), a randomized control trial evaluating the effects of MI training on client change language. We found support for a latent construct of relational skill (i.e., empathy, acceptance, collaboration, and autonomy/support). However, the relational skill construct did not predict client change language. There was support for an indirect effect, such that relational skills predicted RefCT and RefST, and RefCT and RefST predicted client change language. These results suggest that the synergistic implementation of the relational and technical components of MI is critical to facilitating a higher percentage of change talk.

Motivational interviewing training of substance use treatment professionals: A systematic review

Background: Through evaluations of training programs, systematic reviews, and meta-analyses, advances in identifying best practices for disseminating motivational interviewing (MI) have emerged. To advance this work further, inclusion of thorough descriptions of the following is needed in research publications: study (design, trainee characteristics, setting characteristics), training and coaching methods (if applicable), trainer qualifications, and evaluation of MI skills. Methods: The purpose of this study was to systematically evaluate the research on MI training of substance use treatment professionals for the inclusion of such descriptions. Twenty-five studies were reviewed using a scoring rubric developed by the authors. Results: Just over two thirds of the studies (68%) were randomized controlled trials of MI training. The majority of studies provided information about (a) trainee characteristics (professional background = 76%, education = 60%, experience = 56%); (b) setting characteristics (80%); (c) training methods (format = 96%, length = 92%); (d) coaching (76%); and (e) evaluation of MI skills (92%). Conclusion: Findings suggest advancements in MI training studies since previous reviews, especially in regards to the inclusion of feedback and coaching. However, this review also found that inconsistencies in methods and reporting of training characteristics, as well as limited follow-up assessment of trainees' skill, continue to limit knowledge of effective training methods.

Toward an Emerging Role for Motivational Interviewing in Primary Care

PURPOSE OF REVIEW

Implementing Motivational Interviewing (MI) in primary care settings has been problematic due in part to persistent gaps in knowledge. Examples include poor understanding of how to effectively train persons to conduct MI, or of which aspects of MI-related communication are associated with better outcomes for patients. This review describes how recent research findings addressing the knowledge gaps support a growing role for MI in primary care.

RECENT FINDINGS

Two trials of MI training combined classroom time with ongoing coaching and feedback, resulting in enhanced MI ability relative to a control arm where PCPs received minimal or no MI training. A third MI training trial excluded coaching and feedback, failing to increase use of MI. Adding to a growing list of behavioral health-related problems for which MI training has shown some effectiveness, a trial of training PCPs to use MI with depressed patients was associated with significantly improved depressive symptoms. Moreover, aspects of the PCPs' MI-related language and patients' arguments for positive behavior changes, "change talk," appeared to explain the positive effects of MI training on depression outcome. MI-training approaches have improved such that PCPs and possibly other clinic staff may want to consider MI training as a way to more effectively support their patients as they address behavioral health-related problems (e.g., tobacco use). MI training should focus on eliciting "change talk" from patients. Researchers and funding agencies might collaborate to continue closing knowledge gaps in the MI literature.

Short- and Long-Term Effects of Within-Session Client Speech on Drinking Outcomes in the COMBINE Study

OBJECTIVE

There is evidence of a causal chain in motivational interviewing (MI) involving counselor MI-consistent skills, client change language, and outcomes. MI was a key component of the combined behavioral intervention in the Combined Pharmacotherapies and Behavioral Interventions for Alcohol Dependence (COMBINE) Study. Participants in COMBINE were treatment-seeking and medication-seeking, and were required to maintain a period of abstinence before enrollment. Counselors were closely monitored and were temporarily removed from the study for remediation and supervision if their performance fell below threshold. The purpose of this study was to evaluate the MI causal chain among initial-session combined behavioral intervention audio recordings in this unique sample of highly motivated clients and highly monitored counselors.

METHOD

Session 1 audio recordings (N = 254, 73.5% men) were evaluated using the Motivational Interviewing Skill Code Version 2.0 with good interrater reliability. Counselor speech was measured using a summary measure of MI-consistent behavior. Client change language was assessed, using change talk and sustain talk. The outcome measure of drinks per week was computed using the COMBINE data set.

RESULTS

Higher sustain talk was significantly associated with increased drinking during treatment, whereas higher change talk was significantly associated with decreased drinking at the 1-year follow-up. In addition, there were significant indirect effects linking counselor behavior, client speech, and drinking both during treatment and at 1 year.

CONCLUSIONS

Results supported the posited causal chain for MI. Despite somewhat lower variability of counselor behavior and use of a coding instrument that did not capture directional counselor behaviors, counselor behavior, client speech, and drinking outcomes were clearly linked in this unique sample.

A meta-analysis of motivational interviewing process: Technical, relational, and conditional process models of change

OBJECTIVE

In the present meta-analysis, we test the technical and relational hypotheses of Motivational Interviewing (MI) efficacy. We also propose an a priori conditional process model where heterogeneity of technical path effect sizes should be explained by interpersonal/relational (i.e., empathy, MI Spirit) and intrapersonal (i.e., client treatment seeking status) moderators.

METHOD

A systematic review identified k = 58 reports, describing 36 primary studies and 40 effect sizes (N = 3,025 participants). Statistical methods calculated the inverse variance-weighted pooled correlation coefficient for the therapist to client and the client to outcome paths across multiple target behaviors (i.e., alcohol use, other drug use, other behavior change).

RESULTS

Therapist MI-consistent skills were correlated with more client change talk (r = .55, p < .001) as well as more sustain talk (r = .40, p < .001). MI-inconsistent skills were correlated with more sustain talk (r = .16, p < .001), but not change talk. When these indicators were combined into proportions, as recommended in the Motivational Interviewing Skill Code, the overall technical hypothesis was supported. Specifically, proportion MI consistency was related to higher proportion change talk (r = .11, p = .004) and higher proportion change talk was related to reductions in risk behavior at follow up (r = -.16, p < .001). When tested as two independent effects, client change talk was not significant, but sustain talk was positively associated with worse outcome (r = .19, p < .001). Finally, the relational hypothesis was not supported, but heterogeneity in technical hypothesis path effect sizes was partially explained by inter- and intrapersonal moderators.

CONCLUSIONS

This meta-analysis provides additional support for the technical hypothesis of MI efficacy; future research on the relational hypothesis should occur in the field rather than in the context of clinical trials. (PsycINFO Database Record

Variability in motivational interviewing adherence across sessions, providers, sites, and research contexts

Providers' adherence in the delivery of behavioral interventions for substance use disorders is not fixed, but instead can vary across sessions, providers, and intervention sites. This variability can substantially impact the quality of intervention that clients receive. However, there has been limited work to systematically evaluate the extent to which substance use intervention adherence varies from session-to-session, provider-to-provider, and site-to-site. The present study quantifies the extent to which adherence to Motivational Interviewing (MI) for alcohol and drug use varies across sessions, providers, and intervention sites and compares the extent of this variability across three common MI research contexts that evaluate MI efficacy, MI effectiveness, and MI training. Independent raters coded intervention adherence to MI from 1275 sessions delivered by 216 providers at 15 intervention sites. Multilevel models indicated that 57%-94% of the variance in MI adherence was attributable to variability between sessions (i.e., within providers), while smaller proportions of variance were attributable to variability between providers (3%-26%) and between intervention sites (0.1%-28%). MI adherence was typically lowest and most variable within contexts evaluating MI training (i.e., where MI was not protocol-guided and delivered by community treatment providers) and, conversely, adherence was typically highest and least variable in contexts evaluating MI efficacy and effectiveness (i.e., where MI was highly protocolized and delivered by trained therapists). These results suggest that MI adherence in efficacy and effectiveness trials may be substantially different from that obtained in community treatment settings, where adherence is likely to be far more heterogeneous.

The language of change among criminal justice clients: Counselor language, client language, and client substance use outcomes

OBJECTIVE

Counselor and client language have been identified as mechanisms of change in motivational interviewing (MI) counseling sessions. This study evaluated whether language patterns exhibited during MI sessions with substance users in the community would also be found during MI sessions with substance users in the criminal justice system.

METHOD

Forty audio recordings of MI sessions with substance-using probationers were coded and analyzed sequentially using the Motivational Interviewing Skills Code (MISC) 2.5. Analyses examined the relationship between counselor and client language, and the relationship between client language and client substance use after 2 months.

RESULTS

Counselor MI inconsistent language was associated with decreased change talk (lnOR = - 0.76, p < .05) though not with increased sustain talk. Both sustain talk (b = - 4.591, t = - 18.634 p < .001) and MI inconsistent language MIIN (b = - 4.419, t = - 19.886, p < .001) were positively associated with substance use at 2 months. Sustain talk early in the session (i.e., during deciles 1 and 2) was significantly greater among clients who reported using substances at 2 months, compared to clients who did not use substances.

CONCLUSION

These findings are broadly consistent with previous literature documenting the association between counselor language, client language, and client outcome.

Group motivational interviewing for homeless young adults: Associations of change talk with substance use and sexual risk behavior

Homeless young adults exhibit high rates of alcohol and other drug (AOD) use and sexual risk behaviors. This study is a secondary analysis of data collected in a randomized clinical trial of AWARE, a new 4 session group motivational interviewing intervention. AWARE mainly focused on alcohol use and sexual risk behavior given focus group feedback. We used sequential coding to analyze how the group process affected both AOD use and sexual risk behavior at 3-month follow up among homeless young adults by examining facilitator behavior and participant change talk (CT) and sustain talk (ST). We analyzed 57 group session digital recordings of 100 youth (69% male, 74% heterosexual, 28% non-Hispanic white, 23% African American, 26% Hispanic, 23% multiracial/other; mean age 21.75). Outcomes included importance and readiness to change AOD use and risky sexual behavior, AOD use and consequences, number of partners and unprotected sex, and condom self-efficacy. Sequential analysis indicated that facilitator open-ended questions and reflections of CT increased Group CT. Group CT was associated with a lower likelihood of being a heavy drinker 3 months later; Group ST was associated with decreased readiness and confidence to change alcohol use. There were no associations with CT or ST for drug use or risky sexual behavior. Facilitator speech and peer responses were related to CT and ST during the group sessions with this high risk population, which were then associated with individual changes for alcohol use. Further research is needed to explore associations with drug use and sexual risk behavior. (PsycINFO Database Record
