Initial Results from a New College Substance Use Prevention Program Targeting Externalizing and Internalizing Traits.

Objective: College students engage in high rates of risky substance use. Standard college prevention strategies focus on providing feedback about current substance use behaviors and harm reduction strategies but do not address the underlying genetically-influenced risk factors impacting these behaviors. We created an online Personalized Feedback Program (PFP) for college students that targets genetically-influenced externalizing and internalizing risk pathways and provides personalized recommendations and campus resources. College students received personalized feedback on four risk domains (Sensation Seeking, Impulsivity, Extraversion, and Neuroticism). Methods: An open trial (n = 300) was conducted at a large public university in spring of 2021 to assess initial responses to the PFP and evaluate intentions related to future substance use and campus resource use. Results: 81% of students in the open trial reported they enjoyed the Personalized Feedback Program. Participants reported intending to use significantly more campus resources after completing the PFP. Among participants that drank, 39% reported they intended to decrease their alcohol consumption and 41% reported they intended to decrease the number of times they get drunk after completing the PFP; these intentions to reduce use after completing the PFP are higher than rates found in previous studies. Conclusion: Preliminary data indicate that the Personalized Feedback Program may be a complementary method to enhance current college substance use prevention programs.

Prevalence of maternal depression and anxiety symptoms and associations with child mental health outcomes in rural Nepal.

OBJECTIVES: This study describes the prevalence, associated factors and child mental health outcomes related to symptoms of maternal depression and anxiety within 5 years after childbirth in a rural district in Nepal. This association is not well-understood in rural, community-based settings in low- and middle-income countries (LMIC). METHODS: A sample of 347 women with children under 5 years was recruited in September 2019 for a cross-sectional study in the rural Saptari district in Nepal. Multivariable logistic regression was used to investigate the association between maternal depressive or anxiety symptoms and children's experience and impact of emotional and behavioural difficulties. RESULTS: In total, 144 women (41.5%) had moderate or severe depression symptoms and 118 (34%) had anxiety symptoms. Mothers with a lower income were more likely to have anxiety symptoms than the highest income group (OR: 1.8, 95% CI: 1.1-3.0). An association existed between maternal depressive symptoms and the impact of emotional or behavioural difficulties in children (OR: 2.44, 95% CI: 1.02-5.84). In contrast, there was no association between maternal anxiety and child outcomes. CONCLUSIONS: Our findings suggest that the prevalence of probable maternal anxiety and depression symptoms was relatively high in this rural, low-resourced and community-based setting in Nepal. Maternal depressive symptoms were associated with the degree of impact on children's mental health post-infancy, emphasising the importance of improving maternal mental health in the early years of a child's life.

The collaborative study on the genetics of alcoholism: Sample and clinical data.

The collaborative study on the genetics of alcoholism (COGA) is a multi-site, multidisciplinary project with the goal of identifying how genes are involved in alcohol use disorder and related outcomes, and characterizing how genetic risk unfolds across development and in conjunction with the environment and brain function. COGA is a multi-generational family-based study in which probands were recruited through alcohol treatment centers, along with a set of community comparison families. Nearly 18,000 individuals from >2200 families have been assessed over a period of over 30 years with a rich phenotypic battery that includes semi-structured psychiatric interviews and questionnaire measures, along with DNA collection and electrophysiological data on a large subset. Participants range in age from 7 to 97, with many having longitudinal assessments, providing a valuable opportunity to study alcohol use and problems across the lifespan. Here we provide an overview of data collection methods for the COGA sample, and details about sample characteristics and comorbidity. We also review key research findings that have emerged from analyses of the COGA data. COGA data are available broadly to researchers, and we hope this overview will encourage further collaboration and use of these data to advance the field.

Bridging the gap between genetic epidemiological research and prevention: A randomized control trial of a novel personalized feedback program for alcohol and cannabis use.

BACKGROUND: Risky substance use among college students is widespread and associated with numerous negative consequences. We created an online Personalized Feedback Program (PFP) for college students that targets genetically influenced risk pathways for substance use and provides feedback on four risk domains (Sensation Seeking, Impulsivity, Extraversion, and Neuroticism) along with individualized recommendations and campus resources. METHODS: A pilot randomized controlled trial was conducted to evaluate the effects of the PFP on alcohol and cannabis use. First-year college students were randomized to one of four groups: (1) control, (2) PFP, (3) computer-delivered brief motivational intervention (BMI), and (4) combined group that included both the PFP and BMI (PFP+BMI). Students completed a baseline survey (n=251) that assessed alcohol and cannabis use and program satisfaction. Two follow-up surveys were administered at 30-days and 3-months post-intervention to evaluate longitudinal effects on substance use. RESULTS: Participants reported high satisfaction with the PFP. There were no significant effects of intervention group on alcohol use at the follow-up timepoints, though trends were in the expected direction with participants in the PFP group showing decreased odds of alcohol use. There were significant reductions in cannabis use in the PFP group as compared to other groups. CONCLUSIONS: The PFP was met with high satisfaction and had a positive impact on reducing cannabis use. With cannabis use at a historic high among college-aged adults, further research evaluating the effects of the PFP is warranted.

Genetically influenced externalizing and internalizing risk pathways as novel prevention targets.

Objective: Risky substance use among college students is widespread, and associated with numerous adverse consequences. Current interventions focus primarily on students' current substance use; we hypothesize that shifting focus from current use to underlying risk factors is a complementary approach that may improve effectiveness of prevention/intervention programming. This approach aligns with the personalized medicine movement, which aims to harness knowledge about underlying etiological factors to provide individuals with specific information about their unique risk profiles and personalized recommendations, to motivate and enable individuals to better self-regulate their health. Method: Our group is building and evaluating an online Personalized Feedback Program (PFP) for college students that provides feedback about the individual's underlying genetically influenced externalizing and internalizing risk factors for substance use, along with personalized recommendations/resources. The project capitalizes on work from a university-wide research project (Spit for Science; S4S), in which > 12,000 students (˜70% of 5 years of incoming freshmen) are being followed longitudinally to assess substance use and related factors across the college years. In this article, we describe our foundational work to develop the PFP. Results: From the S4S data, we have identified risk factors across four domains (Sensation Seeking, Impulsivity, Extraversion, and Neuroticism) that are correlated with college students' substance use. We developed an online self-guided PFP, in collaboration with professionals from student affairs, and using feedback from students, with the ultimate goal of conducting a randomized clinical trial. Conclusion: The provision of personalized risk information represents a novel approach to complement and extend existing college substance use programming.
