Genetic predisposition to alcohol dependence: The combined role of polygenic risk to general psychopathology and to high alcohol consumption.
High alcohol consumption and alcohol dependence are only partly genetically correlated and they differ considerably in their correlations with other traits. The existence of genetic correlation among alcohol dependence and psychiatric disorders may be attributed to the presence of a general psychopathology factor, the p factor. This study investigates the relationship of polygenic risk to general psychopathology and to high alcohol consumption on alcohol dependence. ⋯ Polygenic risk for alcohol dependence can be split at least into two components, involved in general psychopathology and high alcohol consumption. The first component of PCA based on PRS for different psychiatric disorders allows estimation of the contribution of the polygenic p factor to alcohol dependence. The pleiotropic effects of genetic variants across psychiatric disorders are mainly manifested as alcohol dependence in some patients.

Patient, prescriber, and Community factors associated with filled naloxone prescriptions among patients receiving buprenorphine 2017-18.
Prescribing naloxone to patients at increased opioid overdose risk is a key component of opioid overdose prevention efforts, but little is known about naloxone fills among patients receiving buprenorphine for opioid use disorder, one such high risk group. ⋯ Prescribing naloxone to patients receiving buprenorphine represents a tangible clinical action that can be taken to help prevent opioid overdose deaths. However, despite recommendations to co-prescribe naloxone to patients at increased risk for opioid overdose, rates of filling naloxone prescriptions remain low among patients dispensed buprenorphine. States, insurers, and health systems should consider implementing strategies to facilitate increased co-prescribing of naloxone to at-risk individuals.

Cigarette demand, or relative value, can be assessed via analysis of performance on a hypothetical behavioral economic cigarette purchase task (CPT). Substance purchase tasks are highly amenable to manipulation, namely, external stimuli, instructional changes, or acute stressors. In this regard, the current secondary analysis evaluates the role a novel, computerized stress induction paradigm, the Contextual-Frustration Intolerance Typing Task (C-FiTT), plays in eliciting varying levels of stress and resulting demand. ⋯ The novel C-FiTT paradigm produced comparable effects on tobacco demand relative to in vivo withdrawal induction, indicating that the C-FiTT is a viable procedure by which to influence demand. Reduction of internal and external stressors may be effective in lowering motivation for tobacco. These results highlight the importance of state distress in tobacco demand, and offer a potential avenue for intervention.

Perceived social support in patients with chronic pain with and without opioid use disorder and role of medication for opioid use disorder.
A significant predictor of treatment outcomes for patients with chronic non-cancer pain (CNCP) and opioid use disorder (OUD) is the degree and quality of social support they receive. Specifically, in patients with CNCP and on long-term opioid therapy, the development of OUD tends to be associated with losses in social support, while engagement in treatment for OUD improves support networks. Delivery of the evidence-based OUD treatment medications, methadone and buprenorphine, occurs in clinical environments which patently differ with respect to social support resources. The aims of this study were to describe perceived social support in patients with CNCP without OUD (no-OUD), with OUD and on buprenorphine (OUD-BP), and with OUD and on methadone (OUD-methadone). ⋯ Patients with CNCP and OUD on methadone therapy endorse levels of social support comparable to those without OUD, however those on buprenorphine therapy report significantly less support, bringing implications for OUD treatment outcomes.

Development and examination of the attribution questionnaire-substance use disorder (AQ-SUD) to measure public stigma towards adolescents experiencing substance use disorders.
Public stigma may significantly impact adolescents with substance use disorders (SUDs), leading to limited treatment accessibility and utilization. However, few measures have been validated to assess public SUD stigma towards adolescents. In this study we developed the Attribution Questionnaire-Substance Use Disorder (AQ-SUD) by modifying the Attribution Questionnaire, a commonly used measure of public mental illness stigma. We examined 1) the psychometric properties of the AQ-SUD with supporting data from other stigma scales and 2) preliminary data on adults' perceptions of public stigma toward adolescents with SUDs. ⋯ This study is the first to modify and validate a measure designed to assess perceptions of public SUD stigma towards adolescents, the AQ-SUD. Preliminary analyses suggest that adults view adolescent marijuana use disorders as less severe compared to other SUDs, which may have implications for adults' motivation to support youth in seeking treatment.
