Patterns and Correlates of Polysubstance Use Among Individuals With Severe Alcohol Use Disorder.

AIM: The present study examined patterns and correlates of polysubstance use among individuals with severe alcohol use disorder (AUD). METHODS: Participants were 2785 individuals (63% female; mean age = 43 years, range = 18-78 years) from the Genes, Addiction and Personality Study. All participants met lifetime criteria for severe AUD (6+ symptoms). We used latent class analysis to identify patterns of frequency of lifetime use for cigarettes, marijuana, cocaine, stimulants, sedatives, opioids and hallucinogens. A variety of demographic and behavioral correlates of latent class membership were tested in univariable and multivariable models. RESULTS: A five-class solution was selected: extended range polysubstance use (24.5%); cigarette and marijuana use (18.8%); 'testers,' characterized by high probabilities of smoking 100 or more cigarettes, using marijuana 6+ times, and trying the remaining substances 1-5 times (12.3%); moderate range polysubstance use (17.1%) and minimal use (reference class; 27.3%). In univariable analyses, all potential correlates were related to latent class membership. In the multivariable model, associations with gender, race/ethnicity, age of onset for alcohol problems, dimensions of impulsivity, depressive symptoms, antisocial behavior and family history density of alcohol problems remained significant, though the pattern and strength of associations differed across classes. For instance, sensation-seeking, lack of premeditation and family history were uniquely associated with membership in the extended range polysubstance use class. CONCLUSION: Patterns of polysubstance use are differentially related to demographic and behavioral factors among individuals with severe AUD. Assessing use across multiple substances may inform the selection of targets for treatment and prevention.

Coffee and energy drink use patterns in college freshmen: associations with adverse health behaviors and risk factors.

BACKGROUND: Public health concern over college students mixing caffeine-containing energy drinks (EDs) and alcohol has contributed to an array of ED-focused research studies. One review found consistent associations between ED use and heavy/problem drinking as well as other drug use and risky behaviors (Nutr Rev 72:87-97, 2014). The extent to which similar patterns exist for other sources of caffeine is not known. The present study examined associations between coffee and ED consumption and alcohol, tobacco and other drug use; alcohol use problems; and parental substance abuse and mental health problems in a sample of college freshmen. METHODS: Subjects were N = 1986 freshmen at an urban university who completed an on-line survey about demographics; caffeine; alcohol, tobacco and other drug use; and family history. The sample was 61% female and 53% White. Chi-square analyses and multivariable binary or ordinal logistic regression were used to compare substance use, problem alcohol behavior, and familial risk measures across 3 caffeine use groups: ED (with or without Coffee) (ED + Co; N = 350); Coffee but no ED (Co; N = 761); and neither coffee nor ED (NoCE; N = 875) use. RESULTS: After adjusting for gender and race, the 3 caffeine use groups differed on 8 of 9 symptoms for alcohol dependence. In all cases, the ED + Co group was most likely to endorse the symptom, followed by the Co group and finally the NoCE group (all p < .002). A similar pattern was found for: use 6+ times of 5 other classes of drugs (all p < .05); extent of personal and peer smoking (all p < .001); and paternal problems with alcohol, drugs and anxiety/depression as well as maternal alcohol problems and depression/anxiety (p < .04). CONCLUSIONS: The response pattern was ubiquitous, with ED + Co most likely, Co intermediate, and NoCE least likely to endorse a broad range of substance use, problem alcohol behaviors, and familial risk factors. The finding that the Co group differed from both the ED + Co and NoCE groups on 8 measures and from the NoCE group on one additional measure underscores the importance of looking at coffee in addition to EDs when considering associations between caffeine and other risky behaviors.

Recovery capital among people receiving treatment for opioid use disorder with buprenorphine.

BACKGROUND: Recovery is a multidimensional process that includes health, quality of life, and citizenship. Recovery capital is a strengths-based concept representing the sum of an individual's resources that support recovery. This study (1) describes recovery capital, (2) examines the relationship between recovery capital and treatment duration, and (3) assesses differences by gender in recovery capital among people receiving medication for opioid use disorder (MOUD). METHODS: This is a secondary data analysis of a cross-sectional study, with survey and medical record review components, conducted with patients recruited from an office-based opioid treatment clinic between July and September 2019. Analyses included participants receiving MOUD with buprenorphine who completed the Brief Assessment of Recovery Capital (BARC-10; n = 130). Univariate analyses explored differences by gender. Multivariate linear regression assessed the relationship between BARC-10 total score and length of current treatment episode. RESULTS: Participants were 54.6% women and 67.4% Black with mean age of 42.4 years (SD = 12.3). Mean length of current MOUD treatment was 396.1 days (SD = 245.9). Total BARC-10 scores were high, but participants perceived low community-level resources. Women scored higher than men within the health and purpose recovery dimensions. While length of treatment was not associated with BARC-10 score, experiencing recent discrimination was associated with a significantly lower BARC-10 score. CONCLUSIONS: Recovery capital among individuals receiving MOUD was high suggesting that participants have resources to support recovery, but gender differences and prevalent discrimination highlight areas for improved intervention. More work is needed to investigate recovery capital as an alternative treatment outcome to abstinence in outpatient MOUD populations.

Death anxiety in patients with primary brain tumor: Measurement, prevalence, and determinants.

OBJECTIVE: This study investigated death anxiety in patients with primary brain tumor (PBT). We examined the psychometric properties of two validated death anxiety measures and determined the prevalence and possible determinants of death anxiety in this often-overlooked population. METHODS: Two cross-sectional studies in neuro-oncology were conducted. In Study 1, 81 patients with PBT completed psychological questionnaires, including the Templer Death Anxiety Scale (DAS). In Study 2, 109 patients with PBT completed similar questionnaires, including the Death and Dying Distress Scale (DADDS). Medical and disease-specific variables were collected across participants in both studies. Psychometric properties, including construct validity, internal consistency, and concurrent validity, were investigated. Levels of distress were analyzed using frequencies, and determinants of death anxiety were identified using logistic regression. RESULTS: The DADDS was more psychometrically sound than the DAS in patients with PBT. Overall, 66% of PBT patients endorsed at least one symptom of distress about death and dying, with 48% experiencing moderate-severe death anxiety. Generalized anxiety symptoms and the fear of recurrence significantly predicted death anxiety. SIGNIFICANCE OF RESULTS: The DADDS is a more appropriate instrument than the DAS to assess death anxiety in neuro-oncology. The proportion of patients with PBT who experience death anxiety appears to be higher than in other advanced cancer populations. Death anxiety is a highly distressing symptom, especially when coupled with generalized anxiety and fears of disease progression, which appears to be the case in patients with PBT. Our findings call for routine monitoring and the treatment of death anxiety in neuro-oncology.

Representativeness of patients enrolled in a primary care clinical trial for heavy/problem substance use.

BACKGROUND: The extent to which participants in randomized clinical trials (RCTs) resemble their broader target groups is of particular concern when studying stigmatized conditions such as substance use disorders (SUDs). The present study compared patients who enrolled in a 4-arm clinical trial of SBIRT (screening, brief intervention, and referral to treatment) with eligible patients who declined study participation. METHODS: Participants (N = 1338) were primary care patients who anonymously completed a computer-delivered health survey and screened positive for heavy/problem alcohol or drug use. Those who consented to the RCT (n = 713) were compared with those who declined (n = 625) on a variety of demographic, substance use, and psychosocial characteristics. Variables significant at P < .20 in univariate analyses were then examined using multivariate logistic regression to determine their combined effect. RESULTS: The sample was 60% female and 76% African American, with a mean age of 45.2 years. Patients who consented to participate differed from those who declined on 34 (60%) of the 57 variables studied. The most parsimonious model by multivariate regression found that those who consented were older, more likely to be unemployed, and more likely to endorse prescription drug misuse, problems related to drug use, family history of alcohol problems, trouble falling asleep, and a health professional recommendation to lose weight. CONCLUSION: Patients consenting to the RCT reported a greater number and more severe psychosocial and mental health problems than those who declined study participation. If the higher level of risk among study participants was found in other studies as well, it would raise questions regarding the generalizability of RCT results to broader clinic samples.

Attention-deficit/hyperactivity disorder symptom clusters differentially predict prenatal health behaviors in pregnant women.

OBJECTIVE: To date, most investigations of mental health in pregnant women have focused on depression or substance use. This study aimed to (a) delineate the relationships between symptoms of attention-deficit/hyperactivity disorder (ADHD) and prenatal health behaviors and (b) explore whether the symptom clusters of ADHD differentially predict prenatal health behaviors (e.g., physical strain, healthy eating, prenatal vitamin use). METHOD: A total of 198 pregnant women (mean age = 27.94 years) completed measures of ADHD symptoms, prenatal health behaviors, and depression. RESULTS: Inattention, hyperactivity, and impulsivity/emotional lability all evidenced significant relationships with the prenatal health behaviors, each differentially predicting different prenatal health behaviors. CONCLUSION: As decreased engagement in adequate prenatal health behaviors puts both the mother and fetus at risk for negative birth outcomes, future research should work to develop a brief ADHD screen to be used in obstetric clinics and should investigate these relationships within a sample of women with a diagnosis of ADHD.

Alcohol Use and Problems in Daily and Non-Daily Coffee Drinking College Females.

BACKGROUND: For more than a decade, a large proportion of research on caffeine use in college students has focused on energy drinks (ED), demonstrating an association between ED consumption and heavy/problem alcohol use. The present study examined the relationship between daily coffee consumption and varied measures of alcohol use and problems in a sample of college women. METHODS: Participants were undergraduate females (N=360) attending an urban university in 2001-02 and prior to the rise in ED popularity on college campuses. Analyses compared women who reported drinking coffee daily (DC; 16.9%), to women who did not (NDC; 83.1%) on standardized measures of alcohol use and problems. RESULTS: For both past month and year of drinking, DC women generally reported consuming more alcohol and were 2.1-2.6 times more likely to screen at risk for alcohol problems than their NDC counterparts. DC women were also more likely than NDC women to report problems related to drinking (e.g., experiencing blackouts, inability to stop drinking after they had started). CONCLUSIONS: Findings support potential benefits of health education and screening that goes beyond EDs, focusing on varied forms of caffeine consumption.

Validation of the TAPS-1: A Four-Item Screening Tool to Identify Unhealthy Substance Use in Primary Care.

BACKGROUND: The Tobacco, Alcohol, Prescription Medication, and Other Substance use (TAPS) tool is a combined two-part screening and brief assessment developed for adult primary care patients. The tool's first-stage screening component (TAPS-1) consists of four items asking about past 12-month use for four substance categories, with response options of never, less than monthly, monthly, weekly, and daily or almost daily. OBJECTIVE: To validate the TAPS-1 in primary care patients. DESIGN: Participants completed the TAPS tool in self- and interviewer-administered formats, in random order. In this secondary analysis, the TAPS-1 was evaluated against DSM-5 substance use disorder (SUD) criteria to determine optimal cut-points for identifying unhealthy substance use at three severity levels (problem use, mild SUD, and moderate-to-severe SUD). PARTICIPANTS: Two thousand adult patients at five primary care sites. MAIN MEASURES: DSM-5 SUD criteria were determined via the modified Composite International Diagnostic Interview. Oral fluid was used as a biomarker of recent drug use. KEY RESULTS: Optimal frequency-of-use cut-points on the self-administered TAPS-1 for identifying SUDs were ≥ monthly use for tobacco and alcohol (sensitivity = 0.92 and 0.71, specificity = 0.80 and 0.85, AUC = 0.86 and 0.78, respectively) and any reported use for illicit drugs and prescription medication misuse (sensitivity = 0.93 and 0.89, specificity = 0.85 and 0.91, AUC = 0.89 and 0.90, respectively). The performance of the interviewer-administered format was similar. When administered first, the self-administered format yielded higher disclosure rates for past 12-month alcohol use, illicit drug use, and prescription medication misuse. Frequency of use alone did not provide sufficient information to discriminate between gradations of substance use problem severity. Among those who denied drug use on the TAPS-1, less than 4% had a drug-positive biomarker. CONCLUSIONS: The TAPS-1 can identify unhealthy substance use in primary care patients with a high level of accuracy, and may have utility in primary care for rapid triage.

Computer-Delivered Screening and Brief Intervention for Alcohol Use in Pregnancy: A Pilot Randomized Trial.

BACKGROUND: Although screening and brief intervention (SBI) for unhealthy alcohol use has demonstrated efficacy in some trials, its implementation has been limited. Technology-delivered approaches are a promising alternative, particularly during pregnancy when the importance of alcohol use is amplified. The present trial evaluated the feasibility and acceptability of an interactive, empathic, video-enhanced, and computer-delivered SBI (e-SBI) plus 3 tailored mailings, and estimated intervention effects. METHODS: We recruited 48 pregnant women who screened positive for alcohol risk at an urban prenatal care clinic. Participants were randomly assigned to the e-SBI plus mailings or to a control session on infant nutrition, and were re-evaluated during their postpartum hospitalization. The primary outcome was 90-day period prevalence abstinence as measured by timeline follow-back interview. RESULTS: Participants rated the intervention as easy to use and helpful (4.7 to 5.0 on a 5-point scale). Blinded follow-up evaluation at childbirth revealed medium-size intervention effects on 90-day period prevalence abstinence (OR = 3.4); similarly, intervention effects on a combined healthy pregnancy outcome variable (live birth, normal birthweight, and no neonatal intensive care unit stay) were also of moderate magnitude in favor of e-SBI participants (OR = 3.3). As expected in this intentionally underpowered pilot trial, these effects were nonsignificant (p = 0.19 and 0.09, respectively). CONCLUSIONS: This pilot trial demonstrated the acceptability and preliminary efficacy of e-SBI plus tailored mailings for alcohol use in pregnancy. These findings mirror the promising results of other trials using a similar approach and should be confirmed in a fully powered trial.

Acceptability of a computerized brief intervention for alcohol among abstinent but at-risk pregnant women.

BACKGROUND: Limitations in time and training have hindered widespread implementation of alcohol-based interventions in prenatal clinics. Also, despite the possibility of underreporting or relapse, many at-risk women report that they quit drinking after pregnancy confirmation so that interventions focusing on current drinking may seem unnecessary. The Computerized Brief Intervention for Alcohol Use in Pregnancy (C-BIAP) was designed to (a) be implemented via a handheld device in prenatal clinics, and (b) use a modified brief intervention strategy with women who screen at-risk but report no current drinking. METHODS: The authors administered the C-BIAP to 18 T-ACE (Tolerance, Annoyance, Cut Down, and Eye Opener)-positive pregnant African American women who provided quantitative and qualitative feedback. RESULTS: The C-BIAP received high ratings of acceptability; qualitative feedback was also positive overall and suggested good acceptance of abstinence themes. CONCLUSIONS: Technology may be a feasible and acceptable method for brief intervention delivery with pregnant women who do not report current drinking.

Prevalence and Predictors of Depressive Symptoms in Pregnant African American Women.

African American women may be especially vulnerable to antepartum depression, a major health concern during pregnancy. This study investigated the prevalence and predictors of depressive symptoms in a sample of African American women who were between 14-17 weeks pregnant, a timeframe that is typically thought to be a time of general well-being. Two-thirds reported a CES-D score ≥ 16 indicative of depressive symptomatology. Age, perceived stress (as measured by the Perceived Stress Scale [PSS]), and anxiety (as measured by the State Trait Anxiety Inventory [STAI]) predicted depressive symptoms; the interaction between PSS and STAI scores was also a significant predictor. Our study findings suggest that early identification of stress and anxiety, in addition to depressive symptoms, is vital for intervention with this group.

Personality correlates of past-year alcohol use in individuals with severe alcohol use disorder and a lifetime history of involvement in alcoholics anonymous.

BACKGROUND: Alcohol use disorder (AUD) is a highly impairing condition with important public health impacts. Despite the availability of treatment options for AUD, research shows that few people receive treatment, and even fewer can maintain abstinence/low-drinking levels. This study investigated the role of personality traits in past-year alcohol use among individuals with severe AUD who ever attended Alcoholics Anonymous (AA), a widespread and easily accessible self-help group for alcohol problems. METHODS: Univariable and multivariable regressions were performed separately in females and males with alcohol consumption as an outcome. Socioeconomic factors, genetic liability, and psychopathology were included as covariates in the analyses. RESULTS: Results from the multivariable model indicated that in females who attended AA, greater alcohol use was related to both positive and negative urgency and low sensation seeking, while in males, greater alcohol use was related to positive urgency. Results also showed that, in both sexes, younger age and lower educational levels were associated with greater alcohol use. Moreover, single males and individuals with lower AUD severity were at higher risk of using alcohol in the past year. CONCLUSIONS: These findings highlight sex-specific correlates of drinking in individuals with AUD who engaged in self-help groups. These findings may help to improve treatment options, as personality encompasses modifiable traits that can be targeted in psychological interventions.

Substance Use Disorders in Women.

Substance use disorder (SUD) is among the leading causes of premature morbidity and mortality and imposes significant health, economic, and social burdens. Gender differences have been found in the development, course, and treatment of SUD, with women at increased risk for physiologic and psychosocial consequences compared with men. Reasons for these differences are multifold and include biological, genetic, environmental, and behavioral factors. This article discusses SUD among women, emphasizing clinical considerations for care. Specific topics include epidemiology, sex and gender differences, common comorbidities, screening, diagnosis, treatment, pregnancy, and sociocultural factors.

Baseline Characteristics and Postdischarge Outcomes by Medication for Opioid Use Disorder Status Among Women with Polysubstance Use in Residential Treatment.

Background: Within residential treatment, medication for opioid use disorder (MOUD) is rarely offered, so little is known about group differences by MOUD status. This study characterizes samples of women receiving and not receiving MOUD and explores postdischarge outcomes. Methods: This is a secondary exploratory analysis of a residential clinical trial comparing women receiving treatment as usual (TAU) with those who also received computer-based training for cognitive behavioral therapy (CBT4CBT). Participants were N = 41 adult women with substance use disorder (SUD) who self-reported lifetime polysubstance use. Because 59.0% were prescribed MOUD (MOUD n = 24, no MOUD n = 17), baseline variables were compared by MOUD status; outcomes at 12 weeks postdischarge were compared by MOUD status and treatment condition using chi square and Mann-Whitney U tests. Results: Participants were middle-aged (41.7 ± 11.6 years) and non-Latinx Black (80.4%). Most used substances in the No MOUD group were alcohol, cocaine, and cannabis, and in the MOUD group, most used substances were opioids, cannabis, and cocaine. Women in the MOUD group tended to have more severe SUD. Postdischarge substance use recurrence rates were twice as high in the MOUD group than in the No MOUD group. Among the women in the No MOUD group, those in the CBT4CBT condition increased the number of coping strategies twice as much as those receiving TAU. Conclusion: Postdischarge substance use recurrence differed by MOUD status. CBT4CBT may be a helpful adjunct to personalized residential SUD treatment. The parent study is registered at [www.clinicaltrials.gov (ClinicalTrials.gov identifier: NCT03678051)].

Project BETTER: A Family-Centered, Technology-Delivered Intervention for Pregnant People with Opioid Use Disorder.

Birthing people with opioid use disorder (OUD) face unique stressors during the transition from pregnancy to postpartum that can negatively impact the maternal-infant dyad. This study aimed to describe the development of a family-centered, technology-delivered intervention tailored to help pregnant people receiving medication for OUD (MOUD) prepare for this transition. Formative data from patients and providers identified intervention content: (1) recovery-oriented strategies for the pregnancy-to-postpartum transition; (2) guidance around caring for an infant with opioid withdrawal symptoms; and (3) preparation for child welfare interactions. The content was reviewed in successive rounds by an expert panel and modified. Pregnant and postpartum people receiving MOUD pre-tested the intervention modules and provided feedback in semi-structured interviews. The multidisciplinary expert panel members (n = 15) identified strengths and areas for improvement. Primary areas for improvement included adding content, providing more structure to help participants navigate the intervention more easily, and revising language. Pre-testing participants (n = 9) highlighted four themes: reactions to intervention content, navigability of the intervention, feasibility of the intervention, and recommendation of the intervention. All iterative feedback was incorporated into the final intervention modules for the prospective randomized clinical trial. Family-centered interventions tailored for pregnant people receiving MOUD should be informed by patient-reported needs and multidisciplinary perspectives.

Is pre-college interpersonal trauma associated with cannabis use?

OBJECTIVE: To examine the prevalence and correlates of lifetime cannabis use (i.e., experimental [use 1-5 times] and non-experimental [use ≥ 6 times]) in relation to interpersonal trauma (IPT) above and beyond relevant covariates. PARTICIPANTS: A large (n = 9,889) representative sample of college students at an urban university in the southeastern part of the United States. METHODS: Participants were 4 cohorts of first-year college students who completed measures of demographics, cannabis, alcohol, nicotine, and IPT. Associations were estimated using multinomial logistic regressions. RESULTS: The prevalence of lifetime cannabis use was 28.1% and 17.4% for non-experimental and experimental cannabis use, respectively. IPT was significantly associated with experimental and non-experimental cannabis use above and beyond effects of sex, race, cohort, alcohol, and nicotine. CONCLUSIONS: Results show that cannabis use is prevalent among college students and is associated with IPT above and beyond associations with sex, race, and other substance use.

A longitudinal mediational investigation of risk pathways among cannabis use, interpersonal trauma exposure, and trauma-related distress.

OBJECTIVE: College students are at high risk for cannabis use, interpersonal trauma (IPT) exposure, and trauma-related distress (TRD). Two phenotypic etiologic models posited to explain associations between cannabis use and trauma-related phenotypes are the self-medication (trauma/TRD → cannabis use) and high-risk (cannabis use → trauma/TRD) hypotheses. The primary objective of the present study was to investigate direct and indirect associations among cannabis use, IPT exposure, and TRD above and beyond established covariates. METHOD: The current study used data from the first assessment (i.e., baseline survey at Year 1 Fall) and two follow-up assessments (i.e., Year 1 Spring and Year 2 Spring) from an ongoing longitudinal study on college behavioral health. Participants were 4 cohorts of college students (n = 9,889) who completed measures of demographics, substance use, IPT, and TRD. Indirect effects of IPT on cannabis through TRD (i.e., self-medication) and cannabis on TRD through IPT (i.e., high-risk), including tests of covariate effects (e.g., gender, age, race, cohort, alcohol, nicotine), were simultaneously estimated using a longitudinal mediation modeling framework. RESULTS: Results suggest that more IPT exposure increases risk for TRD and subsequent nonexperimental (use 6+ times) cannabis use, and that experimental (use 1-5 times) and nonexperimental cannabis use increases risk for IPT exposure and subsequent TRD. CONCLUSIONS: Both the self-medication and high-risk hypotheses were supported. Findings support a bidirectional causal relationship between cannabis use and trauma-related phenotypes. Additionally, results highlight areas for colleges to intervene among students to help reduce cannabis use and create a safer environment.

A randomized trial of computer-delivered brief intervention and low-intensity contingency management for smoking during pregnancy.

INTRODUCTION: Implementation of evidence-based interventions for smoking during pregnancy is challenging. We developed 2 highly replicable interventions for smoking during pregnancy: (a) a computer-delivered 5As-based brief intervention (CD-5As) and (b) a computer-assisted, simplified, and low-intensity contingency management (CM-Lite). METHODS: A sample of 110 primarily Black pregnant women reporting smoking in the past week were recruited from prenatal care clinics and randomly assigned to CD-5As (n = 26), CM-Lite (n = 28), CD-5As plus CM-Lite (n = 30), or treatment as usual (n = 26). Self-report of smoking, urine cotinine, and breath CO were measured 10 weeks following randomization. RESULTS: Participants rated both interventions highly (e.g., 87.5% of CD-5As participants reported increases in likelihood of quitting), but most CM-Lite participants did not initiate reinforcement sessions and did not show increased abstinence. CD-5As led to increased abstinence as measured by cotinine (43.5% cotinine negative vs. 17.4%; odds ratio [OR] = 10.1, p = .02) but not for CO-confirmed 7-day point prevalence (30.4% abstinent vs. 8.7%; OR = 5.7, p = .06). Collapsing across CM-Lite status, participants receiving the CD-5As intervention were more likely to talk to a doctor or nurse about their smoking (60.5% vs. 30.8%; OR = 3.0, p = .02). CONCLUSIONS: Low-intensity participant-initiated CM did not affect smoking in this sample, but the CD-5As intervention was successful in increasing abstinence during pregnancy. Further research should seek to replicate these results in larger and more diverse samples. Should CD-5As continue to prove efficacious, it could greatly increase the proportion of pregnant smokers who receive an evidence-based brief intervention.

Lessons learned from a randomized trial of fixed and escalating contingency management schedules in opioid-dependent pregnant women.

BACKGROUND: Contingency management (CM) has shown promise for treating substance use disorders in pregnant women. METHODS: A randomized clinical trial compared the relative efficacy of three conditions on the measures of opioid and cocaine abstinence and days retained in treatment. A total of 133 pregnant patients attending treatment for substance use disorders were randomized either to an escalating reinforcement condition, a fixed reinforcement condition, or an attendance control condition. Conditions were compared on drug abstinence rates and days retained in treatment. RESULTS: As expected, the pooled escalating + fixed conditions received a greater total amount of voucher money than the control condition mean [M = 392.40 (SE = 40.47) vs. 219.74 (SE = 39.78)], respectively; p < .001. However, the escalating and fixed conditions did not differ on the outcome variables of drug abstinence and treatment retention. CONCLUSIONS: The CM conditions examined in the current study did not emerge as superior to the control condition. The lack of significant differences among study conditions may be attributed, in part, to study sample size. Additionally, methodological issues related to the CM intervention may also have compromised outcomes, including delay in reinforcement following the target behavior and limited contact with the reinforcer. SCIENTIFIC SIGNIFICANCE: This study highlights the importance of key CM implementation features, including immediate reinforcement, and adequate access to the reinforcer. It may also be that the reset feature for missing samples in CM interventions is an essential contingency for promoting behavior change.

Short communication: Relationship between social determinants and opioid use disorder treatment outcomes by gender.

BACKGROUND: Social determinants of health (SDoH) influence health outcomes differentially across gender. Gender differences in SDoH have been identified at baseline in opioid use disorder (OUD) treatment studies, but less is known about how SDoH and gender intersect with OUD treatment trajectories. This study aims to identify social correlates of OUD treatment outcomes from five key areas of social determinants separately for men and women receiving buprenorphine for OUD. METHODS: This is a secondary data analysis of a cross-sectional survey with medical record review conducted with patients recruited from an office based opioid treatment clinic. Participants completed surveys between July-September 2019. A 6-month prospective medical record review was conducted to determine treatment retention, substance use recurrence, and buprenorphine continuation. Chi square, T-tests, and Mann Whitney U tested differences in social factors and OUD outcomes by gender. Gender-stratified multivariable logistic and negative binomial regressions assessed predictors of OUD outcomes. RESULTS: Among study participants (n = 142), women were significantly younger (p < 0.001), more likely to live in a safe neighborhood (p = 0.046), and less likely to be employed (p = 0.005) or have substance use recurrence during the study period (p = 0.033) than men. For women, employment (AOR=0.19, p = 0.031) and education (AOR=0.08, p = 0.040) were negatively associated with treatment retention. For men, no social factors were associated with OUD outcomes. CONCLUSIONS: SDoH may impact OUD treatment outcomes differently by gender. Addressing MOUD stigma and implementing patient-centered care strategies may facilitate OUD treatment continuation among employed women in recovery. Gender-related social factors should be considered in OUD treatment research.
