The day-level effects of recovery community center attendance on indicators of recovery wellbeing and risk.

Background: Recovery community centers (RCCs) are a relatively new resource in the recovery support landscape aimed at building their members' recovery capital. In recent years, interest in the value of RCCs has grown, however, no studies have used within-person methods to consider how RCCs may impact the day-to-day lives of their attendees. Using within-person data drawn from members of RCCs, this study examined how visiting RCCs was associated with several same-day indicators of recovery wellbeing and risk: daily sense of meaningfulness, recovery identity, negative affect, and positive affect.

Examining Within- and Between-Person Facets of Negative Affect and Associations with Daily Craving Among Young Adults in Substance Use Disorder Recovery.

The role of negative affect in precipitating drug craving and relapse among young adults in recovery from substance use disorder (SUD) is well documented. However, most studies focus on negative affect as a trait-level congregate of multiple negative emotion states. The present study examined the associations between specific facets of negative affect, college stressors, and craving among young adult college students in SUD recovery.

Using ecological momentary assessments of negative affect and craving during residential opioid use disorder treatment to predict patients' relapse to substance use.

Background: Negative affect (NA) and craving are often independently examined as precipitators of relapse among individuals with substance use disorders, including opioid use disorder (OUD). Recent ecological momentary assessment (EMA) research has revealed that NA and craving frequently co-occur within individuals. Yet we know little about the general patterns of, and variability in, within-person associations between NA and craving, as well as whether the nature and degree of within-person NA-craving coupling predicts post-treatment time-to-relapse.

Prefrontal cortical response to natural rewards and self-reported anhedonia are associated with greater craving among recently withdrawn patients in residential treatment for opioid use disorder.

Both anhedonia and craving are common among patients with opioid use disorder (OUD), and are associated with vulnerability to relapse. Although these constructs are theoretically linked relatively few studies have examined them together. In the current study, recently withdrawn patients (N = 71) in residential treatment for prescription OUD underwent a cue reactivity paradigm while being monitored with functional near-infrared spectroscopy (fNIRS).

Profiles of future expectations among urban adolescents in Cambodia.

Adolescents are tasked with navigating competing priorities, including whether to marry, have children, pursue a job/career, go to college, and contribute to society. The developmental task of building expectations for the future is especially complex for Cambodian adolescents living within a society that strongly prioritizes family obligations yet increasingly provides educational and professional opportunities. The current study, guided by Seginer's (2003) future orientation model, applied latent profile analysis (LPA) to explore patterns of Cambodian adolescents' ( = 580, 64% female, = 15.

Using daily diary methods to understand how college students in recovery use social support.

Collegiate Recovery Communities (CRCs) are important sources of support for college students building and maintaining recovery from substance use disorders. The current study used daily diary data from members of a CRC to examine with which sources of social support students engaged daily, and whether students connected with these sources more on days when they indicated higher-than-usual recovery difficulty, negative affect, and/or school stress. Results indicate that on days when students reported having greater difficulty with recovery maintenance than usual, they had higher odds of being in contact with family members and were expected to talk or spend time with family for longer than usual.

Effectiveness and Utility of Mobile Device Assessment of Subjective Craving during Residential Opioid Dependence Treatment.

Craving is a dynamic state that is both theoretically and empirically linked to relapse in addiction. Static measures cannot adequately capture the dynamic nature of craving, and research has shown that these measures are limited in their capacity to link craving to treatment outcomes. The current study reports on assessments of craving collected 4x-day across 12 days from 73 patients in residential treatment for opioid dependence.

Daily meaningfulness among patients with opioid use disorder: Examining the role of social experiences during residential treatment and links with post-treatment relapse.

Background: A sense of meaningfulness is an important initial indicator of the successful treatment of addiction, and supports the larger recovery process. Most studies address meaningfulness as a static trait, and do not assess the extent to which meaningfulness might vary within an individual, or how it may vary in response to daily life events such as social experiences.

Methods: Ecological momentary assessment (EMA) was used to: 1) examine the amount of within-person variability in meaningfulness among patients in residential treatment for prescription opioid use disorder; 2) determine whether that variability was related to positive or negative social experiences on a daily basis; and 3) assess whether those day-to-day relationships were related to relapse at four months post-treatment.

Longitudinal Links between Adolescent and Peer Conduct Problems and Moderation by a Sensitivity Genetic Index.

The most extensively studied influence on adolescent conduct problem behaviors is peers, and the literature points to genetics as one source of individual differences in peer influence. The purpose of this study was to test the hypothesis that an environmental sensitivity genetic index comprised of DRD4, 5-HTTLPR, and GABRA2 variation would moderate the association between peer and adolescent conduct problems. Latent growth modeling was applied to PROSPER project longitudinal data from adolescents and their peers.

Daily associations among craving, affect, and social interactions in the lives of patients during residential opioid use disorder treatment.

Objective: This study captured the interrelationships among craving, negative affect, and positive and negative social exchanges in the daily lives of patients in residential treatment for opioid use disorders (OUDs).

Method: Participants were 73 patients (77% male), age 19 to 61 (Mage = 30.10, SDage = 10.

Examining the time-varying association of negative affect and covariates with craving during treatment for prescription opioid dependence with two types of mixed models.

Opioid use disorders are chronic and relapse is common. Both negative affect and craving have been suggested antecedents of relapse and have been shown to demonstrate within- and between-person variability, as well as association with each other. The present study extends previous research by examining the covariation of negative affect and craving both within-day and at the person-level during 12 days of treatment among opioid-dependent patients.

Daily social and affective lives of homeless youth: What is the role of teacher and peer social support?

Youth spend a significant amount of time in school surrounded by and interacting with teachers and peers. For doubled-up homeless youth (i.e.

The Pennsylvania Longitudinal Study of Parents and Children (PALSPAC) Twin Registry.

The Pennsylvania Longitudinal Study of Parents and Children Twin Registry was developed to capture a representative sample of multiple births and their parents in the state of Pennsylvania. The registry has two main efforts. The first began in 2012 through recruitment of adolescents in Pennsylvania schools.

Romantic Partner Alcohol Misuse Interacts with Genotype to Predict Frequency of Drunkenness in Young Adulthood.

Previous research has identified the importance of romantic partners-including spouses, significant others, and dating partners-for influencing the engagement in health-risking behaviors, such as alcohol misuse during emerging adulthood. Although genetic factors are known to play a role in the development of young adult alcohol misuse, little research has examined whether genetic factors affect young adults' susceptibility to their romantic partners' alcohol misusing behaviors. The current study tests whether a single nucleotide polymorphism in the gene (rs279845) moderates the relationship between romantic partner alcohol misuse and frequency of drunkenness in young adulthood.

Bayesian hierarchical vector autoregressive models for patient-level predictive modeling.

Predicting health outcomes from longitudinal health histories is of central importance to healthcare. Observational healthcare databases such as patient diary databases provide a rich resource for patient-level predictive modeling. In this paper, we propose a Bayesian hierarchical vector autoregressive (VAR) model to predict medical and psychological conditions using multivariate time series data.

Developmental Change in Adolescent Delinquency: Modeling Time-Varying Effects of a Preventative Intervention and GABRA2 Halpotype Linked to Alcohol Use.

Better integrating human developmental factors in genomic research is part of a set of next steps for testing gene-by-environment interaction hypotheses. This study adds to this work by extending prior research using time-varying effect modeling (TVEM) to evaluate the longitudinal associations between the PROSPER preventive intervention delivery system, a GABRA2 haplotype linked to alcohol use, and their interaction on adolescent delinquency. Logistic and Poisson analyses on eight waves of data spanning ages 11 to 19 (60% female, 90% Caucasian) showed the intervention reduced delinquency from ages 13 to 16.

Twelve Steps, Two Factors: Coping Strategies Moderate the Association Between Craving and Daily 12-Step Use in a College Recovery Community.

Background: Affiliating with 12-step groups appears to reduce relapse risk. By relying on between-person designs, extant research has been unable to examine daily mechanisms through which 12-step group affiliation contributes to recovery.

Objectives: To examine the daily use and factor structure of the 12 steps and intrapersonal predictors and moderators of 12-step use.

Associations between alcohol dehydrogenase genes and alcohol use across early and middle adolescence: Moderation × Preventive intervention.

Data from the in-school sample of the PROSPER preventive intervention dissemination trial were used to investigate associations between alcohol dehydrogenase genes and alcohol use across adolescence, and whether substance misuse interventions in the 6th and 7th grades (targeting parenting, family functioning, social norms, youth decision making, and peer group affiliations) modified associations between these genes and adolescent use. Primary analyses were run on a sample of 1,885 individuals and included three steps. First, we estimated unconditional growth curve models with separate slopes for alcohol use from 6th to 9th grade and from 9th to 12th grade, as well as the intercept at Grade 9.

PROSPER Intervention Effects on Adolescents' Alcohol Misuse Vary by GABRA2 Genotype and Age.

Preventive intervention effects on adolescent alcohol misuse may differ based on genotypes in gene-by-intervention (G x I) interactions, and these G x I interactions may vary as a function of age. The current study uses a novel statistical method, time-varying effect modeling (TVEM), to test an age-varying interaction between a single nucleotide polymorphism in the GABRA2 gene (rs279845) and a preventive intervention in predicting alcohol misuse in a longitudinal study of adolescents (ages 11-20). The preventive intervention was PROSPER, a community-based system for delivery of family and school programs selected from a menu of evidence-based interventions.

Transactions Between Substance Use Intervention, the Oxytocin Receptor (OXTR) Gene, and Peer Substance Use Predicting Youth Alcohol Use.

This study investigated the oxytocin receptor (OXTR) gene's moderation of associations between exposure to a substance misuse intervention, average peer substance use, and adolescents' own alcohol use during the 9th-grade. OXTR genetic risk was measured using five single nucleotide polymorphisms (SNPs), and peer substance use was based on youths' nominated closest friends' own reports of alcohol, cigarette, and marijuana use, based on data from the PROSPER project. Regression models revealed several findings.

Extending Previous cG×I Findings on 5-HTTLPR's Moderation of Intervention Effects on Adolescent Substance Misuse Initiation.

This study addresses replication in candidate gene × environment interaction (cG×E) research by investigating if the key findings from Brody, Beach, Philibert, Chen, and Murry (2009) can be detected using data (N = 1,809) from the PROSPER substance use preventive intervention delivery system. Parallel to Brody et al., this study tested the hypotheses that substance misuse initiation would increase faster from age 11 to age 14 and be higher at age 14 among: (a) 5-HTTLPR short carrier adolescents versus long homozygotes, (b) control versus intervention adolescents, and (c) 5-HTTLPR short carriers in the control condition versus all other participants.

Daily sleep quality affects drug craving, partially through indirect associations with positive affect, in patients in treatment for nonmedical use of prescription drugs.

Objective: Sleep disturbance has been identified as a risk factor for relapse in addiction to a range of substances. The relationship between sleep quality and treatment outcome has received relatively little attention in research on nonmedical use of prescription drugs (NMUPD). This study examined the within-person association between sleep quality and craving in medically detoxified patients in residence for the treatment of NMUPD.

Ecological momentary assessment of affect and craving in patients in treatment for prescription opioid dependence.

Low positive affect (PA) is likely to contribute to risk of relapse; however, it has received relatively little attention in clinical research. This study examined the associations among positive affect, negative affect (NA), and craving in medically withdrawn patients using ecological momentary assessment (EMA). Participants (n=73) provided reports of their PA, NA, and craving 4 times a day for an average of 10.

Differential genetic and environmental influences on developmental trajectories of antisocial behavior from adolescence to young adulthood.

Little research has investigated differential genetic and environmental influences on different developmental trajectories of antisocial behavior. This study examined genetic and environmental influences on liabilities of being in life-course-persistent (LCP) and adolescent-limited (AL) type delinquent groups from adolescence to young adulthood while considering nonviolent and violent delinquency subtypes and gender differences. A genetically informative sample (n = 356, 15-16 years) from the first three waves of In-Home Interview of the National Longitudinal Study of Adolescent to Adult Health was used, with 94 monozygotic and 84 dizygotic pairs of same-sex twins (50% male).
