Parent SMART: Effects of residential treatment and an adjunctive parenting intervention on behavioral health services utilization.

INTRODUCTION: Scant research has examined the impact of residential treatment on adolescent behavioral healthcare utilization post-discharge, even though behavioral healthcare utilization is major driver of healthcare costs. In the primary analyses of a pilot randomized trial, Parent SMART - a technology-assisted intervention for parents of adolescents in residential treatment - was found to improve parental monitoring and parent-adolescent communication, reduce adolescent drinking, and reduce adolescent school-related problems, relative to residential treatment as usual (TAU). The goal of this secondary analysis of the pilot randomized trial was to assess the effects of residential treatment and the adjunctive Parent SMART intervention on both the amount and type of subsequent behavioral healthcare utilization. METHOD: The study randomized sixty-one parent-adolescent dyads to residential TAU (n = 31) or residential TAU plus Parent SMART (n = 30). Of the 61 dyads, 37 were recruited from a short-term residential facility and 24 were recruited from a long-term facility. Adolescents completed a structured clinical interview and self-reported their behavioral health-related visits to the emergency department, nights in residential/inpatient, and outpatient visits over the past 90 days, at baseline, 12-, and 24-weeks post-discharge. Generalized linear mixed models (GLMMs) examined both linear and non-linear (pre- to post- residential treatment) trends, pooled, and stratified by residential facility to examine behavioral health service utilization. RESULTS: Both the linear and pre-post GLMMs revealed that behavioral health-related emergency department visits and residential/inpatient nights decreased across both residential facilities. GLMMs estimating change from the pre- to post period indicated that outpatient visits increased across both facilities. There were no significant effects of the Parent SMART adjunctive intervention in GLMMs, though bivariate tests and the direction of effects signaled that Parent SMART was associated with more nights of residential/inpatient utilization. CONCLUSION: Residential substance use treatment may reduce adolescents' subsequent utilization of costly behavioral healthcare services such as emergency department visits and residential/inpatient nights, while increasing utilization of outpatient services. Parent SMART was not associated with significant changes in behavioral healthcare utilization, but the pattern of results was consistent with prior literature suggesting that stronger parenting skills are associated with greater utilization of non-emergency services.

ReACH2Gether: Iterative Development of a Couples-Based Intervention to Reduce Alcohol use Among Sexual Minority Men Living with HIV and Their Partners.

Unhealthy alcohol use, which encompasses heavy episodic drinking to alcohol use disorder, has been identified as a modifiable barrier to optimal HIV care continuum outcomes. Despite the demonstrated efficacy of couples-based interventions for addressing unhealthy alcohol use, there are no existing couples-based alcohol interventions designed specifically for people living with HIV. This study presents the development and refinement of a three-session couples-based motivational intervention (ReACH2Gether) to address unhealthy alcohol use among a sample of 17 sexual minority men living with HIV and their partners living in the United States. To increase potential population reach, the intervention was delivered entirely remotely. Throughout an original and a modified version, results indicated that the ReACH2Gether intervention was acceptable and there were no reports of intimate partner violence or adverse events. Session engagement and retention were high. In pre-post-test analyses, the ReACH2Gether intervention showed trends in reducing Alcohol Use Disorder Identification Test scores and increasing relationship-promoting dynamics, such as positive support behaviors and goal congruence around alcohol use. Results support the need for continued work to evaluate the ReACH2Gether intervention.

RESUMEN: El consumo no saludable de alcohol, que abarca episodios intensos de consumo hasta llegar a causar trastornos de alcohol, se ha identificado como una barrera modificable para los resultados óptimos continuos de la atención del VIH. A pesar de la eficacia demostrada de las intervenciones basadas en parejas para abordar el consumo no saludable de alcohol, no existen intervenciones de alcohol basadas en parejas diseñadas específicamente para personas que viven con el VIH. Este estudio presenta el desarrollo y perfeccionamiento de una intervención motivacional basada en parejas de tres sesiones (ReACH2Gether) para abordar el consumo no saludable de alcohol entre una muestra de 17 hombres de minorías sexuales que viven con el VIH y sus parejas que viven en los Estados Unidos. Para aumentar el alcance de la población potencial, la intervención se realizó de forma totalmente remota. A lo largo de una versión original y modificada, los resultados indicaron que la intervención ReACH2Gether era aceptable y no hubo informes de violencia de pareja o eventos adversos. El compromiso y la retención de la sesión fueron altos. En los análisis previos y posteriores a la prueba, la intervención ReACH2Gether mostró tendencias en la reducción de las puntuaciones de la prueba de identificación del trastorno por consumo de alcohol y en el aumento de las dinámicas que promueven las relaciones, como comportamientos de apoya positivas y congruencia de objetivos en torno al consumo alcohol. Los resultados respaldan la necesidad de un trabajo continuo para evaluar la intervención ReACH2Gether.

Use of the BACtrack Skyn alcohol biosensor: Practical applications for data collection and analysis.

AIMS: Alcohol biosensors, including the BACtrack Skyn, provide an objective and passive method of continuously assessing alcohol consumption in the natural environment. Despite the many strengths of the Skyn, six key challenges in the collection and processing of data include (1) identifying consumed alcohol; (2) identifying environmental alcohol; (3) identifying and determining the source of missing or invalid data; (4) achieving high participant adherence; (5) integrating Skyn and self-report data; and (6) implications for statistical inference. In this report we outline these challenges, provide recommendations to address them and identify future needs. DESIGN AND SETTINGS: Procedures from several laboratory and field-based pilot studies are presented to demonstrate practical recommendations for Skyn use. Data from a pilot study including a 7-day ecological momentary assessment period are also presented to evaluate effects of environmental alcohol on BACtrack Skyn readings. CONCLUSIONS: To address challenges in the collection and processing of data from the BACtrack Skyn alcohol biosensor, researchers should identify goals in advance of data collection to anticipate the processing necessary to interpret Skyn data. The Transdermal Alcohol Sensor Data Macro (TASMAC) version 2.0 software can help to process data rapidly; identify drinking events, missing data and environmental alcohol; and integrate the sensor with self-report data. Thorough participant orientation and regular contact in field studies can reduce missing data and enhance adherence. Many recommended methods for Skyn use are applicable to other alcohol sensors and wearable devices.

Correspondence between alcohol use measured by a wrist-worn alcohol biosensor and self-report via ecological momentary assessment over a 2-week period.

BACKGROUND: Transdermal alcohol biosensors measure alcohol use continuously, passively, and non-invasively. There is little field research on the Skyn biosensor, a new-generation, wrist-worn transdermal alcohol biosensor, and little evaluation of its sensitivity and specificity and the day-level correspondence between transdermal alcohol concentration (TAC) and number of self-reported drinks. METHODS: Participants (N = 36; 61% male, M age  = 34.3) wore the Skyn biosensor and completed ecological momentary assessment (EMA) surveys about their alcohol use over 2 weeks. A total of 497 days of biosensor and EMA data were collected. Skyn-measured drinking episodes were defined by TAC > 5 µg/L. Skyn data were compared to self-reported drinking to calculate sensitivity and specificity (for drinking day vs. nondrinking day). Generalized estimating equations models were used to evaluate the correspondence between TAC features (peak TAC and TAC-area under the curve (AUC)) and number of drinks. Individual-level factors (sex, age, race/ethnicity, body mass index, human immunodeficiency virus status, and hazardous drinking) were examined to explore associations with TAC controlling for number of drinks. RESULTS: Using a minimum TAC threshold of 5 µg/L plus coder review, the biosensor had sensitivity of 54.7% and specificity of 94.6% for distinguishing drinking from nondrinking days. Without coder review, the sensitivity was 78.1% and the specificity was 55.2%. Peak TAC (ß = 0.92, p < 0.0001) and TAC-AUC (ß = 1.60, p < 0.0001) were significantly associated with number of drinks. Females had significantly higher TAC levels than males for the same number of drinks. CONCLUSIONS: Skyn-derived TAC can be used to measure alcohol use under naturalistic drinking conditions, additional research is needed to accurately identify drinking episodes based on Skyn TAC readings.

Parent SMART (Substance Misuse in Adolescents in Residential Treatment): Pilot randomized trial of a technology-assisted parenting intervention.

Adolescents in residential level of care for substance-related problems have high risk of relapse following discharge. Parent engagement lowers relapse risk, but there are myriad barriers to engaging parents in residential treatment and continuing care. Parent SMART (Substance Misuse in Adolescents in Residential Treatment) is a technology-assisted parenting intervention that was designed to circumvent barriers associated with traditional, office-based continuing care interventions to better engage parents. This pilot randomized trial assessed the acceptability, feasibility, and preliminary effectiveness of Parent SMART as an adjunctive intervention to adolescent residential treatment-as-usual (TAU). Sixty-one parent-adolescent dyads were randomized to Parent SMART+TAU or TAU-only. Thirty-seven dyads were recruited from a short-term facility and 24 dyads were recruited from a long-term facility. Those randomized to Parent SMART received a multi-component technology-assisted intervention combining an off-the-shelf online parenting program, coaching sessions, and a parent networking forum. Parent and adolescent assessments were conducted at baseline, 6, 12, and 24-weeks post-discharge. Feasibility (e.g., parental effectiveness) and acceptability (e.g., parental satisfaction, willingness to recommend the intervention) benchmarks were specified a priori as the primary hypotheses. Secondary effectiveness indicators were the proportion of days adolescent used alcohol, cannabis, and any substance. All acceptability and feasibility benchmarks were met or exceeded among dyads in both short- and long-term residential. Generalized linear mixed models showed no significant effects pooled across sites. Analyses by facility revealed two significant time by condition interactions. Adolescents in short-term residential whose parents received Parent SMART showed fewer drinking days and fewer school problems over time, relative to adolescents whose parents received TAU. Results indicate that Parent SMART was both acceptable and feasible, with preliminary indication of effectiveness among those in short-term residential. A fully-powered trial is warranted to reliably test the effectiveness of Parent SMART and understand possible mechanisms of improvement.

Characterising patterns of alcohol use among heavy drinkers: A cluster analysis utilising alcohol biosensor data.

INTRODUCTION: Previous research has predominately relied on person-level or single characteristics of drinking episodes to characterise patterns of drinking that may confer risk. This research often relies on self-report measures. Advancements in wearable alcohol biosensors provide a multi-faceted objective measure of drinking. The current study aimed to characterise drinking episodes using data derived from a wearable alcohol biosensor. METHODS: Participants (n = 45) were adult heavy drinkers who wore the Secure Continuous Remote Alcohol Monitoring (SCRAM) bracelet and reported on their drinking behaviours. Cluster analysis was used to evaluate unique combinations of alcohol episode characteristics. Associations between clusters and self-reported person and event-level factors were also examined in univariable and multivariable models. RESULTS: Results suggested three unique clusters: Cluster 1 (most common, slowest rate of rise to and decline from peak), Cluster 2 (highest peak transdermal alcohol concentration and area under the curve) and Cluster 3 (fastest rate of decline from peak). Univariable analyses distinguished Cluster 1 as having fewer self-reported drinks and fewer episodes that occurred on weekends relative to Cluster 2. The effect for number of drinks remained in multivariable analyses. DISCUSSION AND CONCLUSIONS: This is the first study to characterise drinking patterns at the event-level using objective data. Results suggest that it is possible to distinguish drinking episodes based on several characteristics derived from wearable alcohol biosensors. This examination lays the groundwork for future studies to characterise patterns of drinking and their association with consequences of drinking behaviour.

A sequential analysis of motivational interviewing technical skills and client responses.

BACKGROUND: The technical hypothesis of Motivational Interviewing (MI) proposes that: (a) client talk favoring behavior change, or Change Talk (CT) is associated with better behavior change outcomes, whereas client talk against change, or Sustain Talk (ST) is associated with less favorable outcomes, and (b) specific therapist verbal behaviors influence whether client CT or ST occurs. MI consistent (MICO) therapist behaviors are hypothesized to be positively associated with more client CT and MI inconsistent (MIIN) behaviors with more ST. Previous studies typically examine session-level frequency counts or immediate lag sequential associations between these variables. However, research has found that the strongest determinant of CT or ST is the client's previous CT or ST statement. Therefore, the objective of this paper was to examine the association between therapist MI skills and subsequent client talk, while accounting for prior client talk. METHODS: We analyzed data from a manualized MI intervention targeting both alcohol misuse and sexual risk behavior in 132 adults seen in two hospital emergency departments. Transcripts of encounters were coded using the Motivational Interviewing Skills Code (MISC 2.5) and an additional measure, the Generalized Behavioral Intervention Analysis System (GBIAS). Using these measures, we analyzed the association between client talk following specific classifications of MICO skills, with the client's prior statement as a potential confounder or effect modifier. RESULTS: With closed questions as the reference category, therapist simple reflections and paraphrasing reflections were associated with significantly greater odds of maintaining client talk as CT or ST. Open questions and complex reflections were associated with significantly greater odds of CT following ST, were not associated significantly with more ST following ST, and were associated with more ST following CT (i.e., through an association with less Follow Neutral). CONCLUSIONS: Simple and paraphrasing reflections appear to maintain client CT but are not associated with transitioning client ST to CT. By contrast, complex reflections and open questions appeared to be more strongly associated with clients moving from ST to CT than other techniques. These results suggest that counselors may differentially employ certain MICO technical skills to elicit continued CT and move participants toward ST within the MI dialogue.

Using topic coding to understand the nature of change language in a motivational intervention to reduce alcohol and sex risk behaviors in emergency department patients.

OBJECTIVE: To elucidate patient language that supports changing a health behavior (change talk) or sustaining the behavior (sustain talk). METHODS: We developed a novel coding system to characterize topics of patient speech in a motivational intervention targeting alcohol and HIV/sexual risk in 90 Emergency Department patients. We further coded patient language as change or sustain talk. RESULTS: For both alcohol and sex, discussions focusing on benefits of behavior change or change planning were most likely to involve change talk, and these topics comprised a large portion of all change talk. Greater discussion of barriers and facilitators of change also was associated with more change talk. For alcohol use, benefits of drinking behavior was the most common topic of sustain talk. For sex risk, benefits of sexual behavior were rarely discussed, and sustain talk centered more on patterns and contexts, negations of drawbacks, and drawbacks of sexual risk behavior change. CONCLUSIONS: Topic coding provided unique insights into the content of patient change and sustain talk. PRACTICE IMPLICATIONS: Patients are most likely to voice change talk when conversation focuses on behavior change rather than ongoing behavior. Interventions addressing multiple health behaviors should address the unique motivations for maintaining specific risky behaviors.

Driving scenes test of the Neuropsychological Assessment Battery (NAB) and on-road driving performance in aging and very mild dementia.

The Driving Scenes test of the new Neuropsychological Assessment Battery (NAB; [Stern, R.A., & White, T. (2003a). Neuropsychological Assessment Battery. Lutz, FL: Psychological Assessment Resources, Inc.]) measures several aspects of visual attention thought to be important for driving ability. The current study examined the relationship between scores on the Driving Scenes test and on-road driving performance on a standardized driving test. Healthy participants performed significantly better on the Driving Scenes test than did very mildly demented participants. A correlation of 0.55 was found between the brief, office-based Driving Scenes test and the 108-point on-road driving score. Furthermore, the Driving Scenes test scores differed significantly across the driving instructor's three global ratings (safe, marginal, and unsafe), and results of a discriminant function analysis indicated that the Driving Scenes test correctly classified 66% of participants into these groups. Thus, the new NAB Driving Scenes test appears to have good ecological validity for real-world driving ability in normal and very mildly demented older adults.

Neuroimaging evidence for the emotional potency of odor-evoked memory.

To assess past behavioral reports of the emotional distinctiveness of odor-evoked memories, functional magnetic resonance imaging (fMRI) was used to compare regions of activation during recall triggered by olfactory and visual cues that were connected to a personally meaningful memory and a comparable control cue presented in olfactory and visual form. Five healthy right-handed females experienced both behavioral and fMRI memory testing. fMRI analyses indicated significantly greater activation in the amygdala and hippocampal regions during recall to the personally significant odor than any other cue, and behavioral responses confirmed that emotional responses were greatest to the personally meaningful odor. These findings provide convincing neurobiological evidence that the subjective experience of the emotional potency of odor-evoked memory is correlated with specific activation in the amygdala during recall and offers new insights into the affective organization of memory.

Experience-dependent activation patterns in human brain during visual-motor associative learning.

Multiple brain regions, including parietal and frontal cortical areas, seem to participate in learning and rehearsing associations between spatially defined visual cues and appropriate motor responses. However, because most previous studies have related learning to changes in brain activation according to elapsed time or number of trials but not categories based on performance, it remains unclear how and when areas implicated in learning sensory-motor associations actually participate in the process. The current experiment used functional magnetic resonance imaging to examine changes in brain activation when participants learned to associate an arbitrarily located visual cue with a finger movement. Associative trials were categorized as incorrect, first correct, or subsequent correct. Participants also performed a spatially compatible visual-motor control task. A group analysis revealed four major findings addressing the behavioral processes occurring during forming and rehearsing visual-motor rules. First, brain networks related to processing associative information, through initial learning to rehearsal, yielded more activation in a myriad of neocortical structures than did a simple motor task. Second, we revealed frontal and parietal areas that differentially processed errors and correct responses. Third, we found frontal-parietal networks that seemed to mediate the transition of learning to rehearsing arbitrary visual-motor associations and that this activation exhibited dynamic characteristics. Last, we found a frontal-parietal network that appeared to have a key role in expressing the learned sensory-motor association. The current results provide a foundation for understanding how neocortical structures participate in the various behavioral processes that combine to form and consolidate novel and arbitrary sensory-motor associations.
