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

Design, Recruitment, and Implementation of Research Interventions Among Youth Experiencing Homelessness: A Systematic Review

Transitional age youth experiencing homelessness (TAY-EH) represent an underserved and understudied population. While an increasing number of empirical interventions have sought to address the high burden of psychopathology in this population, findings remain mixed regarding intervention effectiveness. In this systematic review of behavioral health interventions for TAY-EH, we sought to examine the structural framework in which these interventions take place and how these structures include or exclude certain populations of youth. We also examined implementation practices to identify how interventions involving youth and community stakeholders effectively engage these populations. Based on PRISMA guidelines, searches of Medline, PsycInfo, Embase, Cochrane Central, Web of Science, and ClinicalTrials.gov databases were conducted, including English language literature published before October 2022. Eligible studies reported on interventions for adolescent or young adult populations ages 13-25 years experiencing homelessness. The initial search yielded 3850 citations; 353 underwent full text review and 48 met inclusion criteria, of which there were 33 unique studies. Studies revealed a need for greater geographic distribution of empirically based interventions, as well as interventions targeting TAY-EH in rural settings. Studies varied greatly regarding their operationalizations of homelessness and their method of intervention implementation, but generally indicated a need for increased direct-street outreach in participant recruitment and improved incorporation of youth feedback into intervention design. To our knowledge, this is the first systematic review to examine the representation of various groups of TAY-EH in the literature on substance use and mental health interventions. Further intervention research engaging youth from various geographic locations and youth experiencing different forms of homelessness is needed to better address the behavioral health needs of a variety of TAY-EH.

Understanding effects of the group process on drinking outcomes for emerging adults experiencing homelessness

BACKGROUND

There is little research on group process for motivational interviewing-based group interventions with young people. We examine how change talk, group climate and cohesion, and facilitator empathy among emerging adults experiencing homelessness affect their drinking outcomes.

METHODS

Data come from a clinical trial at three drop-in centers serving emerging adults experiencing homelessness in Los Angeles County and focus on those who received the intervention (n = 132). Participants completed baseline, 3-, 6-, and 12-month follow-up surveys. They were predominantly male and non-white. Group sessions were digitally recorded and coded for percentage change talk (PCT), group climate and cohesion, and facilitator empathy.

RESULTS

Because baseline alcohol use was significantly higher at site 1 than sites 2 and 3, we examined associations separately by site. At 6 months, higher PCT was associated with fewer drinks per drinking day for sites 2 and 3, whereas higher PCT was associated with more drinks per drinking day for site 1. There were no effects of PCT at 12 months. Higher group cohesion scores were associated with fewer drinking days at 6 months; higher facilitator empathy was associated with fewer maximum drinks in a day at both 6 and 12 months. Group climate was not associated with drinking outcomes.

CONCLUSIONS

These findings highlight the importance of measuring multiple factors in the group process to understand outcomes. What is "uttered" during group and what is observed provide different methods to evaluate the group process and allow us to better bridge the gap between research and practice.

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.

College Women's Perceptions of a Friend-Based Intervention to Prevent Alcohol-Involved Sexual Assault

Sexual assault (SA), particularly alcohol-involved SA, remains prevalent among college women. Because SA often begins in social contexts, bystander intervention has become a popular approach to prevention. Bystander interventions train individuals to intervene on behalf of others, including strangers, despite research indicating that intervention is more likely to occur when the bystander has a relationship with the target. Shifting the focus to friends as potential bystanders capitalizes on the qualities of relationship and responsibility that facilitate intervention. College women (N = 35) participated in focus groups (N = 8) during which they viewed a video prototype of a friend-based motivational interviewing (FMI) intervention session conducted with a friend dyad and provided feedback about the relevance and feasibility of using such an approach to reduce SA among friends who drink together in social settings. Content analysis of focus group transcripts yielded three themes: a) Friends as Natural Bystanders; b) The Role of Alcohol in Intervention, and c) Receptivity to FMI intervention. Women indicated that they feel responsible for keeping their friends safe, and that this sense of responsibility facilitates helping behaviors. Women also described ways through which alcohol intoxication can affect helping behavior. Women expressed enthusiasm for the FMI intervention approach and identified its emphasis on friendship and flexible approaches to personal safety as strengths. Findings highlight the promise of FMI intervention approaches that capitalize on the strengths of women's friendship to create safety goals that align with participants' values and overcome barriers to intervention, including alcohol intoxication.

A randomized controlled trial of a brief motivational interviewing-based group intervention for emerging adults experiencing homelessness: 12-Month effects on substance use and sexual risk behavior

INTRODUCTION

Few brief evidence-based risk reduction programs for emerging adults experiencing homelessness focus on the interrelated problems of substance use and sexual risk behavior. This study examines outcomes from a 12-month evaluation of AWARE, a brief Motivational Interviewing (MI)-based group risk reduction intervention for this population.

METHODS

In a cluster randomized crossover trial, N = 276 18-25-year-olds received AWARE or usual care at drop-in centers serving homeless youth in Los Angeles County. We evaluated intervention effects on substance use and condomless sex (primary outcomes), as well as drinking consequences and protective strategies, number of casual partners, self-efficacy, and motivation for change (secondary outcomes).

RESULTS

AWARE participants self-reported reductions in their alcohol use and negative consequences from drinking, and an increase in use of drinking protective strategies. AWARE participants also reported an initial decrease in drug use other than marijuana, followed by a slight uptake later on, as well as an initial increase in importance of cutting down on other drug use followed by a decrease. Control group participants did not show change in these outcomes. Among those who reported casual sex partners at both baseline and 12-month surveys, exploratory analyses indicated that AWARE participants had a 29 % decline in condomless sex with casual partners compared to a 6 % decline for control group participants.

CONCLUSIONS

Findings build on our pilot work by demonstrating that AWARE has long-term benefits on drinking among emerging adults experiencing homelessness. Further work should seek to strengthen its long-term effectiveness in reducing drug use in this population.

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.

Study protocol for a group-based motivational interviewing brief intervention to reduce substance use and sexual risk behavior among young adults experiencing homelessness

BACKGROUND

Young people experiencing homelessness have alarmingly high rates of alcohol and other drug (AOD) use, which is associated with sexual risk behaviors such as unprotected sex, trading sex, and sex with multiple casual partners. Few risk reduction programs for this population have been developed and rigorously evaluated, particularly those that address both of these interrelated behaviors, use a collaborative and non-judgmental approach, and are feasible to deliver in settings where homeless young people seek services. This paper describes the protocol of a study evaluating a four-session Motivational Interviewing (MI)-based group risk reduction intervention for this population. The protocol has been shown to be efficacious in pilot work over 3 months with 200 homeless young adults [1]. The current study seeks to refine the intervention protocol and evaluate the program on a larger scale.

METHODS/DESIGN

In a cluster-cross-over randomized controlled trial, 18-25 year olds will receive the AWARE risk reduction program (n = 200) or standard care (n = 200) at one of three drop-in centers serving homeless youth in the Los Angeles area. We will evaluate intervention effects on primary outcomes of AOD use and sexual risk behavior, as well as secondary outcomes of health-related quality of life and social stability, over a 12-month period.

DISCUSSION

This project has the potential to fill a significant gap in prevention services by demonstrating that a brief intervention, feasible to deliver within settings where young people experiencing homelessness typically seeks services, can significantly reduce the interrelated problems of AOD use and sexual risk behavior.

Advancing Analytic Approaches to Address Key Questions in Mechanisms of Behavior Change Research

OBJECTIVE

Interest in studying mechanisms of behavior change (MOBCs) in substance use disorder (SUD) treatments has grown considerably in the past two decades. Much of this work has focused on identifying which variables statistically mediate the effect of SUD treatments on clinical outcomes. However, a fuller conceptualization of MOBCs will require greater understanding of questions that extend beyond traditional mediation analysis, including better understanding of when MOBCs change during treatment, when they are most critical to aiding the initiation or maintenance of change, and how MOBCs themselves arise as a function of treatment processes.

METHOD

In the present study, we review why these MOBC-related questions are often minimally addressed in empirical research and provide examples of data analytic methods that may address these issues. We highlight several recent studies that have used such methods and discuss how these methods can provide unique theoretical insights and actionable clinical information.

RESULTS

Several statistical approaches can enhance the field's understanding of the timing and development of MOBCs, including growth-curve modeling, time-varying effect modeling, moderated mediation analysis, dynamic systems modeling, and simulation methods.

CONCLUSIONS

Adopting greater diversity in methods for modeling MOBCs will help researchers better understand the timing and development of key change variables and will expand the theoretical precision and clinical impact of MOBC research. Advances in research design, measurement, and technology are key to supporting these advances.

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.

Complexities with group therapy facilitation in substance use disorder specialty treatment settings

In spite of increased attention to research-based interventions for substance use disorders (SUDs), a formidable research-practice gap impedes the implementation of evidence-based treatments (EBTs). An underappreciated dimension of this gap is a mismatch in treatment modality: Whereas clinical trial and implementation research has focused primarily on individual therapy, the majority of SUD specialty treatment is in group format, with open-enrolling groups being most common. This study aims to narrow this research-practice gap by exploring clinicians' perspectives on complexities with group therapy facilitation in SUD specialty treatment settings. Semi-structured interviews were conducted with 13 group clinicians from among three outpatient SUD specialty clinics-diverse in their operational structures, treatment philosophies, clientele, and services-located in the same Midwestern U.S. metropolitan area. Interview questions addressed organizational characteristics, services provided, group therapy curricula, and use of EBTs or other structured treatments. Clinicians emphasized the importance of having flexibility in facilitating groups, through built-in group processes and clinicians' own adaptions and accommodations; this flexibility was especially emphasized for the use of EBTs or manualized interventions. Clinicians also had difficulties with group facilitation generally, as evidenced by their reported difficulty in managing complex group dynamics, their limited group therapy experience and training, and their reliance on educational groups. We discuss specific strategies for improved innovation and implementation of EBTs for SUD group therapy.

Working memory capacity and addiction treatment outcomes in adolescents

BACKGROUND

Brief addiction treatments including motivational interviewing (MI) have shown promise with adolescents, but the factors that influence treatment efficacy in this population remain unknown. One candidate is working memory, the ability to hold a fact or thought in mind. This is relevant, as in therapy, a client must maintain and manipulate ideas while working with a clinician. Working memory depends upon brain structures and functions that change markedly during neurodevelopment and that can be negatively impacted by substance use.

OBJECTIVES

In a secondary analysis of data from a clinical trial for adolescent substance use comparing alcohol/marijuana education and MI, we evaluated the relationship between working memory and three-month treatment-outcomes with the hypothesis that the relationship between intervention conditions and outcome would be moderated by working memory.

METHODS

With a diverse sample of adolescents currently using alcohol and/or marijuana (N = 153, 64.7% male, 70.6% Hispanic), we examined the relationship between baseline measures of working memory and alcohol and cannabis-related problem scores measured at the three-month follow-up.

RESULTS

The results showed that lower working memory scores were associated with poorer treatment response only for alcohol use, and only within the education group. No relationship was found between working memory and treatment outcomes in the MI group.

CONCLUSION

The results suggest that issues with working memory capacity may interfere with adolescents' ability to process and implement didactic alcohol and marijuana content in standard education interventions. These results also suggest that MI can be implemented equally effectively across the range of working memory functioning in youth.
