Background: Primary care settings like federally qualified health centers (FQHC) are optimal locations to identify individuals with substance use disorders (SUD) and link them to SUD treatment, yet successful linkage has proven difficult. Recovery management checkups for primary care (RMC-PC) is a promising method for increasing linkage to care, engagement in treatment, and reducing substance use.

Methods: Participants (n = 266) who received screening, brief intervention, and referral to treatment (SBIRT) at four FQHC sites and needed SUD treatment were randomized to receive SBIRT only or SBIRT+RMC-PC.

Introduction: Substance use treatment outcomes are challenging to predict: myriad potentially relevant factors influence outcomes, including age, sex, motivations, and history of victimization.

Methods: The current study seeks to assess these factors in adolescents through an evaluation of the relationship between distinct victimization profiles, sex, and cognitive factors related to substance use treatment outcomes-specifically motivation, self-efficacy, and reasons for quitting-and the relationship between these factors and posttreatment outcomes. We report sex differences in the prevalence of specific types of victimization; females are more likely than males to report poly-victimization alongside higher levels of traumagenic characteristics such as fearing for your life, chronic abuse, abuse by a trusted individual, or negative reactions to disclosure.

University of Southern California, Keck School of Medicine, Department of Psychiatry and Behavioral Sciences, 2250 Alcazar Street, Suite 2200, Los Angeles, CA 90033, USA.

Among American veterans, the behavioral health impact of potentially morally injurious experiences (PMIEs) has recently garnered attention. There is heterogeneity in the types of experiences that are classified as PMIEs, and different PMIEs may be differentially associated with various outcomes. We aimed to explore heterogeneity in PMIEs among veterans, and whether PMIE classes are differentially associated with several behavioral health outcomes (i.

Background: While there is some evidence and conceptual plausibility that tobacco product use is associated with hypertension incidence and that this association varies by sex, extant longitudinal research had been conducted prior to the emergence of e-cigarette and dual e-cigarette and cigarette use.

Aims And Methods: Data were analyzed from the US Population Assessment of Tobacco and Health study for adults with no lifetime history of hypertension at wave 1 (2013-2014) who completed waves 2-4 follow-up surveys (2014-2018; n = 16 434). Sex-stratified weighted covariate-adjusted multivariable Cox regression models were used to examine the association between established current e-cigarette or cigarette exclusive or dual-use (as a time-varying and time-lagged regressor) and subsequent self-reported hypertension onset.

A mobile-based pregaming drinking prevention intervention for college students: study protocol for a randomized controlled trial.

Addict Sci Clin Pract

June 2022

Suzanne Dworkak-Peck School of Social Work; Department of Population and Public Health Sciences, Keck School of Medicine; USC Institute for Addiction Science, University of Southern California, Los Angeles, United States.

Background: Pregaming is a high-drink context popular among college students that often leads to elevated blood alcohol levels and negative consequences. Over 15 years of research studies have demonstrated that pregaming represents one of the riskiest known behaviors among college students, yet no pregaming-specific interventions have been developed to help prevent this behavior. General brief interventions for students do not reduce pregaming behavior and may not be appropriate, as they do not help students develop skills unique to the pregaming context that could help them drink less.

There is a well-established correlation between health and adverse childhood experiences (ACEs). Arguments have been made to expand ACE scales to include indicators of racism and structural inequalities. In this paper, we use nationally representative data to examine the relationships between latent groups of an expanded adversity scale and a broad range of child health outcomes.

Background: The COVID-19 pandemic caused numerous stressors that may have been linked to substance use among college students.

Methods: We analyzed data from the Fall 2020 Healthy Minds Study ( = 15,995), a non-probability sample of students attending one of 28 universities, who completed an online survey during the COVID-19 pandemic (September - December 2020). Using multivariable logistic regression, we examined the associations between COVID-19 stressors (concern, racial/ethnic discrimination, financial distress, infection, illness of loved one, death of loved one, caregiving) and substance use (alcohol, cigarette, marijuana), adjusting for age, gender, race/ethnicity, and international student status.

Insecure romantic attachment style has been associated with greater substance use and higher risk sexual behavior, but the temporal nature of these associations is not well-understood. This study examined whether having a more insecure attachment style was associated with greater engagement in higher-risk sexual behavior over time and, if so, whether this was mediated by more frequent alcohol use. We used three annual waves of survey data from a diverse California cohort (N = 2371) who were assessed from ages 19 to 21-22 years.
