In-session processes of brief motivational interventions in two trials with mandated college students

Learning & motivational talk in smoking cessation interventions: An examination of session language in two randomized trials

OBJECTIVES

Motivational Interviewing (MI), a client-centered approach that seeks to evoke and resolve ambivalence, and health education (HE), which provides health information and advice, may both provide some benefit to unmotivated smokers. In HE, it is possible that client language reflective of new learning, or "learning talk" (LT), and rejection of health advice, or "rejection talk," (RT), may uniquely reflect intent of subsequent behavior change.

METHODS

This project utilized MI and HE sessions from two randomized clinical trials (RCTs), one in a low-income, diverse community civilian sample of 255 unmotivated smokers, and the other in a sample of Veterans with mental illness who were unmotivated smokers (n = 55). Mixed methods approaches were utilized to reliably code sessions using the Motivational Interviewing Skill Code 2.5 (MISC 2.5)1 and a refined Learning Talk coding system2.

RESULTS

Reliability of LT and RT codes ranged from fair to excellent (ICCs from 0.43-0.93).

CONCLUSION

LT appears to be a unique construct and its impact on post-session changes in smoking is warranted.

PRACTICE IMPLICATIONS

This system can be used in a study to code existing interventions for smokers using both MI and HE techniques and relate in-session client LT to subsequent smoking behaviors.

Technical and relational process in MI sessions with a sample of Hispanic/Latinx adults who engage in heavy drinking: A latent growth mediation model

The current study tests the Motivational Interviewing (MI) technical and relational hypotheses in a sample of Hispanic/Latinx adults (N = 276) who engage in heavy alcohol consumption. MI causal theory hypothesizes that therapist use of MI consistent skills (i.e., technical hypothesis) and embodiment of the MI Spirit (i.e., relational hypothesis) will elicit client change talk, which is a putative mechanism of positive client outcome after the session. We tested these associations in a rigorous parallel process latent growth curve mediation modeling framework. The data are from a completed randomized clinical trial of a culturally-adapted (CAMI) versus un-adapted MI targeting hazardous alcohol use and consequences. Results. The unconditional growth models for the mediator (i.e., proportion of change talk relative to sustain talk) and two study outcomes (i.e., percent of heavy drinking days; alcohol-related consequences) showed a linear effect over a 12-month period with a slower rate of growth at later timepoints. Contrary to expectations, the latent growth mediation models did not show relationships between MI-consistent skills (i.e., technical predictor) or latent MI Spirit (i.e., relational indicator) and the slope factor for proportion change talk. The slope factor for proportion change talk was also not associated with the slope factors for percent heavy drinking and consequences over follow-up. Conclusions. In this novel population for MI process analysis, the technical and relational hypotheses were not supported. Studies that are exploratory may be needed to further investigate the causal model in populations that are not often represented in MI process research.

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.

The Relationship Between Drinking Behavior and Conversational Processes During a Brief Alcohol Reduction Intervention for People with HIV

People with HIV (PWH) frequently engage in unhealthy alcohol use, which can adversely affect antiretroviral adherence and HIV disease progression. Brief interventions based on Motivational Interviewing (MI), including the Brief Negotiated Interview (BNI), can help to reduce drinking. This study examines MI processes observed during a single 15-20 min BNI session delivered by social workers to PWH with unhealthy alcohol use (N = 59) in the context of a stepped care intervention to reduce alcohol consumption. BNI sessions were coded for technical and relational processes encouraged in MI, such as autonomy support, instructive language, and self-exploration. Multiple regression analyses explored the relationship between: (1) Participants' pre-intervention drinking behaviors (weekly drinks and heavy drinking days) and these MI processes, and (2) MI processes and intervention outcomes. Results indicated that PWH who reported more weekly drinks at baseline engaged in less self-exploration, while social workers delivering the BNI used less instructive language for those who reported more heavy drinking days. PWH who engaged in more self-exploration and received more autonomy support had fewer heavy drinking days 6 months after the intervention. These findings suggest the value of providing more opportunities within BNIs to encourage self-exploration, as it may help to enhance intervention efficacy.

Examining client self-exploration in motivational interviewing: Preliminary psychometrics of an observational rating measure

PURPOSE

We examine in-session self-exploration among Latinx heavy drinkers who received a motivational interview (MI) to reduce heavy drinking. The goals of this study are to report the validity and reliability of an adaptation of the Global Client Rating for Self-Exploration from the Motivational Interviewing Skill Code (MISC SE).

METHOD

The study measured the MISC SE as three subscales (Emotional, Cognitive, New Learning/Developing Discrepancy SE) to assess underlying processes that might allow for higher predictive validity in relation to behavioral change (drinking) outcomes. The study created a dichotomous variable, Personally Relevant Vulnerable Making (PR-VM), to distinguish the disclosure of particularly sensitive material related to drinking behavior. The study used the measure of Everyday Discrimination as a criterion variable for the PR-VM measure. The study collected observationally rated data for n = 158 participants.

RESULTS

Subscales showed moderate correlations with the MISC SE (r = 0.421 to 0.574, p < .001). The MISC SE was not associated with number of drinking days or percent heavy drinking days at 3-month follow-up. Cognitive and New Learning/Developing Discrepancy SE were associated with fewer drinking days (r = -0.247 to -0.266, p < .005), and Cognitive SE was associated with percent heavy drinking days (r = -0.169, p < .05), Subscale interrater reliability was comparable to the MISC SE (ICC = 0.72 to 0.86). The study observed higher mean scores on the Everyday Discrimination scale when session PR-VM was present than when not present (t (df = 118) = -3.02, p < .005).

CONCLUSIONS

The subscale adaptation of the SE measure may provide a sensitive approach to understanding how self-exploration relates to behavior change in the context of MI.

Analysis of Behavior Classification in Motivational Interviewing

Analysis of client and therapist behavior in counseling sessions can provide helpful insights for assessing the quality of the session and consequently, the client's behavioral outcome. In this paper, we study the automatic classification of standardized behavior codes (i.e. annotations) used for assessment of psychotherapy sessions in Motivational Interviewing (MI). We develop models and examine the classification of client behaviors throughout MI sessions, comparing the performance by models trained on large pretrained embeddings (RoBERTa) versus interpretable and expert-selected features (LIWC). Our best performing model using the pretrained RoBERTa embeddings beats the baseline model, achieving an F1 score of 0.66 in the subject-independent 3-class classification. Through statistical analysis on the classification results, we identify prominent LIWC features that may not have been captured by the model using pretrained embeddings. Although classification using LIWC features underperforms RoBERTa, our findings motivate the future direction of incorporating auxiliary tasks in the classification of MI codes.

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.

The sampling precision of research in five major areas of psychology

After obtaining a sample of published, peer-reviewed articles from journals with high and low impact factors in social, cognitive, neuro-, developmental, and clinical psychology, we used a priori equations recently derived by Trafimow (Educational and Psychological Measurement, 77, 831-854, 2017; Trafimow & MacDonald in Educational and Psychological Measurement, 77, 204-219, 2017) to compute the articles' median levels of precision. Our findings indicate that developmental research performs best with respect to precision, whereas cognitive research performs the worst; however, none of the psychology subfields excelled. In addition, we found important differences in precision between journals in the upper versus lower echelons with respect to impact factors in cognitive, neuro-, and clinical psychology, whereas the difference was dramatically attenuated for social and developmental psychology. Implications are discussed.

Cognitive-Affective Change Mechanisms in Personalized Normative Feedback via the Articulated Thoughts in Simulated Situations Paradigm

The research explored explanatory mechanisms of change for a personalized normative feedback (PNF) intervention, through an adapted application of the Articulated Thoughts in Simulated Situation (ATSS) cognitive think-aloud paradigm. A sample of 70 (51% female) U.S. adjudicated students were randomly assigned to one of three conditions: a PNF-ATSS condition, a PNF-Only condition (without ATSS), and an active Control+ATSS condition which received psychoeducation about alcohol use. Students in both the PNF-Only and PNF-ATSS conditions reported significant reductions in their misperceived peer drinking norms and alcohol-related consequences at the 30-day follow-up, relative to students in the control condition. Participants in the PNF-ATSS condition drank significantly fewer drinks per week at follow-up than participants in the PNF-Only condition, but not less than participants in the control condition. Significant indirect effects were found for the ATSS codes of participants’ neutrality and believability toward PNF content. This study presents a proof of concept for an adapted ATSS think-aloud methodology as a clinical science intervention tool to specify the cognitive-affective processes of change linked to complex intervention for particular problems, persons, and contexts.

A Sequential Analysis of Clinician Skills and Client Change Statements in a Brief Motivational Intervention for Young Adult Heavy Drinking

This study examined sequential relationships between clinician skills and client statements about behavior change in a randomized clinical trial comparing a brief motivational intervention (BMI) to a relaxation training control condition (REL) in a sample of heavy drinking young adults. Clinician and client interactions (N = 167) were assessed according to two established observational rating systems. Sequential analyses examined the transitional associations between clinicians' use of MI-eliciting skills (i.e., questions and reflections), MI-supportive skills (e.g., affirmations, emphasize client autonomy, statements of support), MI-inconsistent skills (e.g., confrontations, unsolicited advice), and subsequent client statements about behavior change (i.e., change talk or sustain talk). In both conditions, clinicians' use of MI-elicitation skills operated in a manner that was largely consistent (100% in BMI; 84% in REL) with the directional relationships proposed by MI theory (i.e., The Technical Hypothesis). More detailed analyses of the BMI condition showed clinician skills were related to statements about behavior change somewhat differently in drinking compared to coping discussions. While elicitations of change talk were associated with increased odds of their intended response (i.e., distal drinking and proximal coping change talk), elicitations of proximal coping sustain talk were associated with higher odds of proximal change talk. MI-supportive skills were also associated with increased odds of proximal change talk, and instances of proximal sustain talk were rare in the sample. This fine-grained analysis presents sequential transitions to client change and sustain talk with greater classification specificity than has been previously reported. Such efforts have the potential to advance our understanding of the function of MI skills in promoting client discussions about drinking (i.e., evoking) and coping (i.e., planning) behavior change.

Is fidelity to motivational interviewing associated with alcohol outcomes in treatment-seeking 60+ year-old citizens?

BACKGROUND

Part of the variability in treatment outcomes for Motivational Interviewing (MI) may be explained by differences in the fidelity to MI. The Motivational Interviewing Treatment Integrity manual version 4 (MITI 4) is an improved measure of fidelity to elements of MI. It is not known whether the fidelity to MI, as measured by the MITI 4, is related to treatment outcome.

OBJECTIVES

To examine whether fidelity to MI is associated with alcohol use outcomes - predictive validity of the MITI 4.

METHOD

Twenty percent of the recorded sessions at the Danish sites of the Elderly Study were randomly drawn and coded for fidelity to MI with the MITI 4. The Elderly Study was an international, randomized controlled trial, in which people 60 years or older with Alcohol Use Disorders received either four weeks of Motivational Enhancement Therapy (MET) or four weeks of MET combined with up to eight additional sessions of the Community Reinforcement Approach- Senior (MET+CRA-S). Elements of MI and summary scores of the MITI 4 were used as predictors in a mixed effects regression analysis. Treatment outcomes were use of alcohol and consequences of drinking at 26-weeks follow-up.

RESULTS

In total, 423 sessions representing 238 participants were randomly drawn and coded for fidelity to MI. Mean values of the treatment elements indicated high fidelity to MI, with higher fidelity to MI in the MET sessions, as compared to CRA-S sessions. None of the predictors in the multilevel model analyses were associated with outcome at follow-up. Exploratory analysis indicated reverse associations between one measure of MI-fidelity and drinking outcomes in the combined treatment (CRAS).

CONCLUSION

The fidelity of the MI intervention, received by participants in this study, did not predict better treatment outcomes. MI may be less effective in populations which are already committed to change behavior. As expected and validating for the MITI 4, fidelity to MI-elements was lower in the combination of MI with other treatment approaches. Additionally, the timing of MI in these combined settings might be important for effectiveness.

Improvement in therapist skills over sessions in brief motivational interventions predicts client language and alcohol use outcomes

Brief motivational interventions (BMIs) are widely used and efficacious interventions that address alcohol misuse in mandated college students. Consistent with motivational interviewing (MI; Miller & Rollnick, 2013) theory, within-therapist improvements in MI-consistent (MICO) skills over time-that is, as a therapist gains skill through repeated practice-may be associated with concurrent increases in client change language and subsequent changes in behavior. This study examined how therapist skill changed over time and whether within-therapist improvement in MICO skills impacted in-session client change language and subsequent alcohol-related outcomes. BMI sessions (N = 228) from 2 randomized clinical trials that had led to significant reductions in alcohol use and alcohol-related problems in mandated student drinkers were coded using the Motivational Interviewing Skills Code 2.0 (Miller, Moyers, Ernst, & Amrhein, 2003). In both studies, the BMI consisted of a single 45- to 60-min session. Analyses examined session-by-session changes in therapist MICO skills, client change language, and alcohol use outcomes. Therapist MICO skills improved over time, and there were significant increases in client change language and decreases in client discussion of topics other than personal alcohol use. Among relatively heavy-drinking clients, those treated by a more experienced therapist demonstrated greater reductions in alcohol use; however, this association was not mediated by client change language. Increased experience conducting BMIs improved therapist MICO skills over time, which in turn increased the focus on personal alcohol use during the session. However, it remains unclear how client language predicts behavior change following a BMI. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

A randomized clinical trial evaluating the efficacy of a brief alcohol intervention supplemented with a substance-free activity session or relaxation training

OBJECTIVE

Behavioral economic theory suggests that a reduction in alcohol use is most likely when there is an increase in rewarding substance-free activities. Anxiety has also been linked to heavy drinking, and strategies to reduce anxiety may enhance alcohol interventions. The goal of this 2-site randomized controlled clinical trial was to evaluate the efficacy of a brief alcohol intervention that was supplemented with either a behavioral economic substance-free activity session (SFAS) or a relaxation training (Relaxation training [RT]) session.

METHOD

Participants were 393 college students (61% female, mean age = 18.77 years) who reported 2 or more past-month heavy drinking episodes. Participants were randomized to 1 of 3 conditions: (a) assessment; (b) alcohol brief motivational intervention (BMI) plus SFAS; or (c) BMI plus RT. Both treatment conditions included 2 in-person sessions plus a phone booster session. Outcomes were evaluated 1-, 6-, 12-, and 16-months postintervention.

RESULTS

Generalized linear mixed models indicated that the combination of a BMI plus either the SFAS or RT was associated with significant reductions in alcohol use and problems across the 16-month follow-up compared with assessment only. There were no significant differences between the two active treatment conditions. Changes in proportional reinforcement from substance-related activities, and protective behavioral strategies mediated treatment effects.

CONCLUSION

Two-session (plus booster) interventions that combine BMI and either substance-free activity enhancement or RT can result in enduring reductions in alcohol misuse among college drinkers. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

The role of therapist MI skill and client change talk class membership predicting dual alcohol and sex risk outcomes

OBJECTIVE

We investigated the technical model of motivational interviewing (MI) in a dual-outcome intervention (i.e., alcohol, sexual risk; N = 164; 57% female).

METHOD

We identified latent classes of client change statements, based on the proportion of change talk (CT) over the session. We then examined whether outcomes were related to CT class, and whether the relations between MI skill and outcomes varied by CT class.

RESULTS

We found three classes of alcohol-CT and two classes of sexual risk-CT. While CT class membership did not predict outcomes directly, greater therapist MI-consistent skill was associated with fewer heavy drinking days in the increasing alcohol-CT class. For sexual risk outcomes, therapist MI-consistent skill was associated with reduced odds of condomless sex for the low sexual risk-CT class.

CONCLUSIONS

The relation of therapist MI consistency to outcomes appears to be a function of client CT during the session.

Motivational interviewing technical process and moderated relational process with underage young adult heavy drinkers

This study tested technical and relational processes hypothesized to explain the therapeutic benefit of an efficacious brief motivational interview (BMI). A randomized controlled trial compared the efficacy of a BMI to an attention-matched control (i.e., relaxation training [REL]) for reducing heavy alcohol consumption and associated negative consequences. Participants were underage, past-month heavy drinkers recruited from community settings (N = 167; ages 17-20; 62% female; 59% White). Data were collected on session recordings, using established motivational interviewing process measures. Statistical analyses followed 3 steps. First, a latent class model determined the optimal class solution for characterizing proportion change talk means within BMI and REL. Next, the probability of proportion change talk class membership was examined as a mediator and then as a moderated mediator of BMI efficacy. The latent class model yielded a 3-class solution, including a low-increasing proportion change talk class (n = 61), a moderate-increasing proportion change talk class (n = 97), and a nonlinear proportion change talk class (n = 7). Across the outcomes examined, membership in the moderate-increasing class rather than the low-increasing class mediated BMI effects on alcohol-related consequences at 6 weeks. Mediation tests for consequences at 3 months and heavy drinking were nonsignificant. Moderated mediation results for therapist empathy and MI Spirit were nonsignificant. Findings suggest that moderate increases in prochange statements, relative to anti- or neutral-change statements, help explain BMI effects on reducing alcohol-related negative consequences soon after intervention.

Mechanisms of behavior change in motivational interviewing: do we understand how MI works?

This work provides an overview of Motivational Interviewing (MI) theory, the nature of the evidence for its mechanisms of action, and considers future directions. There are three hypotheses purported to explain how MI works: The Technical Hypothesis, the Relational Hypothesis, and the Conflict Resolution Hypothesis. In contrast to the latter two hypotheses, the Technical Hypothesis has received the most empirical attention in the MI process literature. Research shows that clinician technical skills in MI are well-defined, they relate to the intended client mechanisms (i.e. change talk and sustain talk), but the evidence supporting client mechanisms as predictors of subsequent changes to behavior is less conclusive. Future research and clinical implications are briefly considered.

Do what you say and say what you are going to do: A preliminary meta-analysis of client change and sustain talk subtypes in motivational interviewing

Objective: This meta-analysis examines the predictive validity of client change language subtypes in motivational interviewing (MI) sessions addressing addictive behavior change. Method: A systematic review identified k = 13 primary studies, contributing 16 MI conditions (N = 1556). The pooled correlation coefficient was used to assess the significance, direction, and strength of seven language subtypes (i.e., reason, desire, need, ability, commitment, taking steps, and other) by three valences (i.e., frequency positive or change talk, frequency negative or sustain talk, and proportion change talk) and their relationship to subsequent engagement in addictive behavior. Results: For frequency measures, more sustain talk related to reason, desire, ability, and other were associated with more addictive behavior at follow up. Other change talk was associated with MI outcomes but in an unexpected direction (i.e., more addictive behavior). Proportion measures showed more proportion change talk-reason and -other statements were associated with less addictive behavior at follow up. Sensitivity analyses indicated some heterogeneity and instability of effect sizes, but no evidence of publication bias. Conclusions: This preliminary meta-analysis suggests that aggregate measures of change and sustain talk are comprised of statement subtypes that are not equally meaningful in predicting outcome following MI for addictive behavior change.

Medication adherence in patients with schizophrenia: a qualitative study of the patient process in motivational interviewing

BACKGROUND

Motivational interviewing (MI) may be an effective intervention to improve medication adherence in patients with schizophrenia. However, for this patient group, mixed results have been found in randomized controlled trials. Furthermore, the process of becoming (more) motivated for long-term medication adherence in patients with schizophrenia is largely unexplored.

METHOD

We performed a qualitative multiple case study of MI-sessions to analyse the interaction process affecting motivation in patients with schizophrenia. Fourteen cases of patients with schizophrenia, who recently experienced a psychotic relapse after medication-nonadherence, were studied, comprising 66 audio-recorded MI-sessions. In the MI-sessions, the patients expressed their cognitions on medication. We used these cognitions to detect the different courses (or patterns) of the patients' ambivalence during the MI-intervention. We distinguished successful and unsuccessful cases, and used the cross-case-analysis to identify success factors to reach positive effects of MI.

RESULTS

Based on the expressed cognitions on medication, we found four different patterns of the patient process. We also found three success factors for the intervention, which were a trusting relationship between patient and therapist, the therapist's ability to adapt his MI-strategy to the patient's process, and relating patient values to long-term medication adherence.

CONCLUSIONS

The success of an MI-intervention for medication adherence in patients with schizophrenia can be explained by well-defined success factors. Adherence may improve if therapists consider these factors during MI-sessions.

Design and feasibility testing of a novel group intervention for young women who binge drink in groups

BACKGROUND

Young women frequently drink alcohol in groups and binge drinking within these natural drinking groups is common. This study describes the design of a theoretically and empirically based group intervention to reduce binge drinking among young women. It also evaluates their engagement with the intervention and the acceptability of the study methods.

METHODS

Friendship groups of women aged 18-35 years, who had two or more episodes of binge drinking (>6 UK units on one occasion; 48g of alcohol) in the previous 30 days, were recruited from the community. A face-to-face group intervention, based on the Health Action Process Approach, was delivered over three sessions. Components of the intervention were woven around fun activities, such as making alcohol free cocktails. Women were followed up four months after the intervention was delivered.

RESULTS

The target of 24 groups (comprising 97 women) was recruited. The common pattern of drinking was infrequent, heavy drinking (mean consumption on the heaviest drinking day was UK 18.1 units). Process evaluation revealed that the intervention was delivered with high fidelity and acceptability of the study methods was high. The women engaged positively with intervention components and made group decisions about cutting down. Twenty two groups set goals to reduce their drinking, and these were translated into action plans. Retention of individuals at follow up was 87%.

CONCLUSIONS

This study successfully recruited groups of young women whose patterns of drinking place them at high risk of acute harm. This novel approach to delivering an alcohol intervention has potential to reduce binge drinking among young women. The high levels of engagement with key steps in the behavior change process suggests that the group intervention should be tested in a full randomised controlled trial.

Mechanisms of Behavior Change Within Peer-Implemented Alcohol Interventions

OBJECTIVE

Colleges continue to experience a high number of referred students because of campus alcohol violations. Subsequently, there has been a trend to use peer-implemented minimal interventions (PMIs), often using motivational interviewing (MI). However, little is known about how PMIs facilitate behavior change. This study aims to examine the mechanisms of behavior change within PMIs and their influence on alcohol reduction among mandated students.

METHOD

Participants (N = 146; mean age = 18.7 years; 67% male; 94% White) were college students who violated campus alcohol policy at a Northeastern liberal arts college who received a 15-minute PMI addressing their alcohol use. The Motivational Interviewing Skill Code (Miller et al., 2003) was used to identify peer counselor behaviors that were MI consistent (MICO), client change talk (CT), and client self-exploration.

RESULTS

MICO behaviors were positively associated with CT and self-exploration. Client CT and self-exploration were negatively associated with alcohol-related outcomes. Furthermore, mediational models examining MICO behaviors revealed effects for two paths: (a) from MICO to client CT to reduced alcohol use; and (b) from MICO to client self-exploration to reduced alcohol-related consequences and use.

CONCLUSIONS

These data support the primary causal chain examining the influence of MICO on in-session client behaviors and related post-session behavior change in PMIs among at-risk students.

Towards an understanding of self-directed language as a mechanism of behavior change: A novel strategy for eliciting client language under laboratory conditions

Introduction

Change talk (CT) and sustain talk (ST) are thought to reflect underlying motivation and be important mechanisms of behavior change (MOBCs). However, greater specificity and experimental rigor is needed to establish CT and ST as MOBCs. Testing the effects of self-directed language under laboratory conditions is one promising avenue. The current study presents a replication and extension of research examining the feasibility for using simulation tasks to elicit self-directed language.

Methods

First-year college students (N = 92) responded to the Collegiate Simulated Intoxication Digital Elicitation, a validated task for assessing decision-making in college drinking. Verbal responses elicited via free-response and structured interview formats were coded based on established definitions of CT and ST, with minor modifications to reflect the non-treatment context. Associations between self-directed language and alcohol use at baseline and eight months were examined. Additionally, this study examined whether a contextually-based measure of decision-making, behavioral willingness, mediated relationships between self-directed language and alcohol outcome.

Results

Healthy talk and unhealthy talk independently were associated with baseline alcohol use across both elicitation formats. Only healthy talk during the free-response elicitation was associated with alcohol use at follow up; both healthy talk and unhealthy talk during the interview elicitation were associated with 8-month alcohol use. Behavioral willingness significantly mediated the relationship between percent healthy talk and alcohol outcome.

Conclusions

Findings support the utility of studying self-directed language under laboratory conditions and suggest that such methods may provide a fruitful strategy to further understand the role of self-directed language as a MOBC.

•

Feasibility test for eliciting self-directed alcohol statements in the laboratory

•

Healthy talk reliably elicited and measured in response to a simulation task

•

Healthy talk associated with current and future alcohol use in college students

Provides a novel strategy for testing self-direct language as a mechanism of change

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

REMIT: Development of a mHealth theory-based intervention to decrease heavy episodic drinking among college students

mHealth apps are an effective means of delivering health interventions, and the college-age population is particularly proficient at using apps. Informed by current theories of Ecological Momentary Interventions (EMI), Motivational Interviewing (MI), and the Transtheoretical Model (TTM) of Change, investigators have developed a self-monitoring app-Reductions through Ecological Momentary/Motivational Intervention/Transtheoretical (REMIT)-with the aim of reducing hazardous drinking among college students. The app was developed using the Integrate, Design, Assess, and Share (IDEAS) framework. This step-by-step process for developing digital behavior change interventions was conducted in five phases to: (1) understand the users, (2) determine target behavior, (3) base the intervention in behavioral theory; (4) create delivery strategies, and (5) develop the REMIT prototype. REMIT uses assessments (informed by EMI) and components of MI and TTM to guide administration of nine modules designed to engage users in reducing alcohol use and related problems. REMIT users self-monitor their alcohol consumption and develop strategies to change drinking behaviors using a range of easy-to-use features, such as the Virtual Coach, automated text messages, interactive gaming mechanisms (gamification), drink consumption tracking, and Blood Alcohol Concentration (BAC) calculators. mHealth interventions have been shown to reduce alcohol use among college students when they are applied in real-life, real-time contexts. REMIT is a theory-based app that incorporates user-friendly features to reduce hazardous drinking among college students. The next step is to conduct a pilot trial to test the efficacy of the app and enhance the REMIT prototype.

Trajectories of in-session change language in brief motivational interventions with mandated college students

OBJECTIVE

Brief motivational interventions (BMIs) are currently the most efficacious individual intervention for mandated college students. However, little is known about how BMIs facilitate client language in relation to subsequent changes in alcohol use and problems in mandated student samples.

METHOD

The current study used the Motivational Interviewing Skills Code (MISC 2.0; Miller, Moyers, Ernst, & Amrhein, 2003) to code BMI sessions (N = 252) from 2 randomized clinical trials that led to significant reductions in alcohol use and alcohol-related problems in mandated student drinkers. A proportion of change language was calculated for each decile (1st to 10th) of the BMI sessions.

RESULTS

Latent class analyses of in-session speech indicated that there were 3 distinct trajectories of change language over the course of the session: high (n = 59), increasing (n = 122), and low (n = 71). Members of the high trajectory group showed higher rates of alcohol-related problems prior to the BMI and members of the low trajectory group were more likely to be male. Six months following the BMI, members of the high and low trajectory groups demonstrated significant reductions in alcohol use and problems, and members of the increasing trajectory group only reduced alcohol-related problems.

CONCLUSIONS

Associations among the 3 trajectories of client change language and subsequent reductions in alcohol use and problems partially supported the technical hypothesis of MI efficacy. Client factors as well as the nature of the discussion of personalized feedback may determine the link between in-session client language and subsequent behavior change. (PsycINFO Database Record

Initial Progress Toward Development of a Voice-Based Computer-Delivered Motivational Intervention for Heavy Drinking College Students: An Experimental Study

BACKGROUND

Computer-delivered interventions have been shown to be effective in reducing alcohol consumption in heavy drinking college students. However, these computer-delivered interventions rely on mouse, keyboard, or touchscreen responses for interactions between the users and the computer-delivered intervention. The principles of motivational interviewing suggest that in-person interventions may be effective, in part, because they encourage individuals to think through and speak aloud their motivations for changing a health behavior, which current computer-delivered interventions do not allow.

OBJECTIVE

The objective of this study was to take the initial steps toward development of a voice-based computer-delivered intervention that can ask open-ended questions and respond appropriately to users' verbal responses, more closely mirroring a human-delivered motivational intervention.

METHODS

We developed (1) a voice-based computer-delivered intervention that was run by a human controller and that allowed participants to speak their responses to scripted prompts delivered by speech generation software and (2) a text-based computer-delivered intervention that relied on the mouse, keyboard, and computer screen for all interactions. We randomized 60 heavy drinking college students to interact with the voice-based computer-delivered intervention and 30 to interact with the text-based computer-delivered intervention and compared their ratings of the systems as well as their motivation to change drinking and their drinking behavior at 1-month follow-up.

RESULTS

Participants reported that the voice-based computer-delivered intervention engaged positively with them in the session and delivered content in a manner consistent with motivational interviewing principles. At 1-month follow-up, participants in the voice-based computer-delivered intervention condition reported significant decreases in quantity, frequency, and problems associated with drinking, and increased perceived importance of changing drinking behaviors. In comparison to the text-based computer-delivered intervention condition, those assigned to voice-based computer-delivered intervention reported significantly fewer alcohol-related problems at the 1-month follow-up (incident rate ratio 0.60, 95% CI 0.44-0.83, P=.002). The conditions did not differ significantly on perceived importance of changing drinking or on measures of drinking quantity and frequency of heavy drinking.

CONCLUSIONS

Results indicate that it is feasible to construct a series of open-ended questions and a bank of responses and follow-up prompts that can be used in a future fully automated voice-based computer-delivered intervention that may mirror more closely human-delivered motivational interventions to reduce drinking. Such efforts will require using advanced speech recognition capabilities and machine-learning approaches to train a program to mirror the decisions made by human controllers in the voice-based computer-delivered intervention used in this study. In addition, future studies should examine enhancements that can increase the perceived warmth and empathy of voice-based computer-delivered intervention, possibly through greater personalization, improvements in the speech generation software, and embodying the computer-delivered intervention in a physical form.

Marijuana use in the context of alcohol interventions for mandated college students

OBJECTIVE

Concurrent use of marijuana and alcohol among college students is highly prevalent and associated with negative consequences. It remains unclear whether marijuana use is influenced by or lessens the efficacy of alcohol interventions delivered within a stepped-care approach.

METHOD

Participants were 530 college students who violated campus alcohol policy and were mandated to an alcohol-focused brief advice (BA) session. Participants who reported continued risky alcohol use (4+ heavy drinking episodes and/or 5+ alcohol-related consequences in the past month) six weeks following the BA session were randomized to a brief motivational intervention (BMI; n=211) or assessment only (AO; n=194) condition. Follow-up assessments were conducted 3, 6, and 9months' post-intervention.

RESULTS

Multiple regression analyses revealed that marijuana user status did not influence drinking outcomes following the BA session. However, hierarchical linear models suggested that marijuana users who were randomized to BMI or AO reported higher levels of binge drinking, pBAC and consequences compared to non-users, regardless of condition. Despite this, heavy drinking marijuana users and nonusers had equivalent reductions on alcohol use outcomes following the BMI sessions. Marijuana users who received a BMI did not significantly reduce marijuana use frequency compared to participants in the AO group.

CONCLUSION

Use of marijuana did not lessen the efficacy of the BA session on alcohol use or consequences. Findings suggest that marijuana users respond similarly to alcohol interventions as do non-users and can benefit from brief or more intensive alcohol interventions. A marijuana-focused intervention may be warranted to facilitate changes in marijuana use.

Do brief motivational interventions reduce drinking game frequency in mandated students? An analysis of data from two randomized controlled trials

College students frequently engage in drinking games (DGs) and experience a variety of consequences as a result. It is currently unknown whether brief motivational interventions (BMIs) that provide feedback on DG participation can reduce this high risk behavior. This study examined outcome data from 2 randomized clinical trials to examine whether BMIs facilitate change in DG frequency and how these changes may occur. Mandated college students (Trial 1, N = 198, 46% female; Trial 2, N = 412; 32% female) were randomized to BMI or comparison control conditions. Hierarchical linear modeling (HLM) was used to compare the BMI and comparison groups to determine whether the BMI reduced DG participation over time. Percent change talk (PCT) during the discussion of DG during the session was examined as a predictor of change in DG frequency, and gender was examined as a moderator of treatment effects. Controlling for regular drinking frequency, participants who received a BMI did not significantly reduce their DG frequency relative to the comparison group in either sample, and the BMI was equally ineffective at reducing DG behavior for men and women. DG-related PCT during the BMI was associated with lower DG frequency at the second follow-up in both trials. In Trial 1, PCT during the BMI was associated with less steep increases in DG frequency across the course of all follow-ups. Effects of PCT on DG behavior were not moderated by gender. Findings did not support hypothesized reductions in DG participation following a BMI. Future research should explore whether targeted DG-specific interventions could reduce DG participation and the role of in-session client language in facilitating such change.

Ambivalence: Prerequisite for success in motivational interviewing with adolescents?

BACKGROUND AND AIMS

The exploration and resolution of ambivalence play an essential role in motivational interviewing (MI) theory. However, most adolescent MI studies have not examined ambivalence as a contributor to behaviour change. This paper reviewed research findings on the role of ambivalence in the adolescent change process.

METHODS AND RESULTS

We undertook a narrative review of the published empirical and theoretical literature on ambivalence and mechanisms of change in MI for adolescents and found that current MI evaluations appear not to have access to reliable and valid measures of ambivalence in adolescence or neuroimaging methods to evaluate the mechanisms of treatment response.

CONCLUSIONS

Improved instrumentation is needed to assess adolescents' ambivalence in clinical and research settings. Innovative methodology, including neuroimaging, may help identify factors mediating relationships between adolescents' ambivalence and treatment response.

A randomized controlled trial of culturally adapted motivational interviewing for Hispanic heavy drinkers: Theory of adaptation and study protocol

BACKGROUND

The NIH Strategic Plan prioritizes health disparities research for socially disadvantaged Hispanics, to reduce the disproportionate burden of alcohol-related negative consequences compared to other racial/ethnic groups. Cultural adaptation of evidence-based treatments, such as motivational interviewing (MI), can improve access and response to alcohol treatment. However, the lack of rigorous clinical trials designed to test the efficacy and theoretical underpinnings of cultural adaptation has made proof of concept difficult.

OBJECTIVE

The CAMI2 (Culturally Adapted Motivational Interviewing) study design and its theoretical model, is described to illustrate how MI adapted to social and cultural factors (CAMI) can be discriminated against non-adapted MI.

METHODS AND DESIGN

CAMI2, a large, 12month randomized prospective trial, examines the efficacy of CAMI and MI among heavy drinking Hispanics recruited from the community (n=257). Outcomes are reductions in heavy drinking days (Time Line Follow-Back) and negative consequences of drinking among Hispanics (Drinkers Inventory of Consequences). A second aim examines perceived acculturation stress as a moderator of treatment outcomes in the CAMI condition.

SUMMARY

The CAMI2 study design protocol is presented and the theory of adaptation is presented. Findings from the trial described may yield important recommendations on the science of cultural adaptation and improve MI dissemination to Hispanics with alcohol risk.

Does a Brief Motivational Intervention Reduce Frequency of Pregaming in Mandated Students?

BACKGROUND

Pregaming, also known as frontloading or predrinking, is a common but risky drinking behavior among college students. However, little is known about the way in which a brief motivational intervention (BMI) addressing general alcohol use and consequences may impact pregaming frequency.

OBJECTIVES

This study examined whether mandated students reduced frequency of pregaming following a BMI when pregaming was spontaneously discussed and whether gender moderated these effects.

METHODS

Participants (n = 269, 32% female) were mandated college students who had received a campus-based alcohol citation and continued to exhibit risky alcohol use six weeks after receiving a brief advice session. Participants were randomized to a brief motivational intervention (BMI, n = 145) or assessment only (AO, n = 124) and completed follow-up assessments at 3, 6, and 9 months postintervention. Hierarchical Linear Modeling (HLM) was used to examine both between-person (Level 2) effects (i.e., condition) and within-person (Level 1) effects (i.e., time) on pregaming frequency. Analyses examining discussions of pregaming within the BMI were conducted using a subsample of the BMI sessions which had been transcribed (n = 121).

RESULTS

Participants in the BMI group did not significantly reduce the frequency of pregaming compared to those in the AO group, even when pregaming was explicitly discussed during the BMI. Moreover, the BMI was equally ineffective at reducing pregaming frequency for both males and females. Conclusion/Importance: Pregaming frequency appears to be resistant to conventional intervention efforts, but recent research suggests several innovative strategies for addressing pregaming in the college student population.

Drinking Location and Pregaming as Predictors of Alcohol Intoxication Among Mandated College Students

BACKGROUND

Both drinking location and pregaming have been associated with heavy alcohol use among college students, yet the manner by which they uniquely contribute to alcohol intoxication remains unclear.

OBJECTIVE

The current study examined the unique utility of drinking location and pregaming in predicting alcohol intoxication among college students who violated campus alcohol policy.

METHOD

Between 2011 and 2012, mandated college students who reported drinking prior to their referral events (N = 212, 41% female, 80% White, Mage = 19.4 y) completed a computerized assessment of drinking location and related behaviors as part of larger research trial. Chi-squared statistics, t-tests, one-way analyses of covariance, and regression were used to examine study aims.

RESULTS

Participants were most likely (44%) to report drinking in off-campus housing prior to the referral event, and approximately half (47%) reported pregaming. Alcohol intoxication on the night of the referral event differed significantly as a function of both drinking location and pregaming, but pregaming did not moderate the association between drinking location and alcohol intoxication among mandated students. Female birth sex, pregaming, and drinking at either fraternities or off-campus housing predicted greater levels of alcohol intoxication on the night of the referral incident, while drinking in a residence hall/dorm predicted lower intoxication.

CONCLUSIONS/IMPORTANCE

Drinking location and pregaming are distinct predictors of alcohol intoxication among mandated college students. Future interventions may benefit from targeting both where and how college students consume alcohol.

Factors Influencing Uptake of Rapid HIV and Hepatitis C Screening Among Drug Misusing Adult Emergency Department Patients: Implications for Future HIV/HCV Screening Interventions

In this randomized, controlled trial among 957 English- or Spanish-speaking drug misusing adult emergency department (ED) patients, we determined if a tailored brief intervention (BI) increased uptake of rapid HIV/HCV screening, and identified factors associated with greater screening uptake. Rapid HIV/HCV screening uptake was greater in the control than the BI arm (45 vs. 38 %; p < 0.04). Screening uptake depended on elapsed study time and which research staff member offered testing. In the control arm, uptake was lowest for those spending <30 or ≥90 min in the study. In the BI arm, screening uptake generally increased over time. Tailored BI content specifically addressing participant HIV/HCV knowledge, HIV/HCV risk behaviors, or need for HIV/HCV screening was not associated with greater screening uptake. These study findings suggested factors that should be considered when designing future ED-based screening initiatives, such as elapsed study time, who offers testing, and the content of interventions.

Associations among Trauma, Posttraumatic Stress, and Hazardous Drinking in College Students: Considerations for Intervention

Students with trauma and posttraumatic stress are disproportionately at risk for heavy drinking and for alcohol-related consequences. Brief motivational interventions (BMIs) have been shown to reduce hazardous drinking in college students, and could serve as a first-line approach to reduce heavy drinking in students with trauma and posttraumatic stress (PTS). Yet the standard BMI format may not adequately address the factors that lead to hazardous drinking in these students. Here, we review the literature on PTS and hazardous drinking in college students, and highlight cognitive (self-efficacy, alcohol expectancies) and behavioral (coping strategies, emotion regulation skills, protective behaviors) factors that may link trauma and PTS to drinking risk. Incorporating these factors into standard BMIs in a collaborative way that enhances their personal relevance may enhance intervention efficacy and acceptability for these at-risk students.

Participant report of therapist-delivered active ingredients in a telephone-delivered brief motivational intervention predicts taking steps towards change

OBJECTIVE

Given the widespread potential for disseminating Motivational Interviewing (MI) through technology, the question of whether MI active ingredients are present when not delivered in person is critical to assure high treatment quality. The Participant Rating Form (PRF) was developed and used to evaluate therapist-delivered active ingredients in phone-delivered MI with hazardous drinking Emergency Department patients.

METHOD

A factor analysis of all PRFs completed after receiving one call (n=256) was conducted. Multiple regression analysis was used to examine whether PRF factors predicted a measure of motivation to change -- taking steps-at the second call (n=214).

RESULTS

The majority of participants were male (65%), with a mean age of 32 years and with an average alcohol ASSIST (Alcohol, Smoking, and Substance Involvement Screening Test) score of 20.5 (SD = 7.1). Results of the factor analysis for the PRF revealed Relational (working collaboration) and Technical (MI behaviors) factors. After controlling for demographics, alcohol severity, and baseline readiness, the technical factor predicted self-report of increased taking steps towards change while the relational factor did not explain any additional variance.

CONCLUSIONS

Our study adds to the growing literature investigating patient perspectives of therapist skill as a source of information to better understand MI active ingredients. The PRF is a feasible instrument for measuring the patient's experience of phone-based MI. Results indicate that MI active ingredients of change (relational and technical components) were present in the telephone intervention as hypothesized. Clinical Trial Registration # 01326169.
