Causal inference under treatment interference is a challenging but important problem. Past studies usually make strong assumptions on the structure of treatment interference in order to estimate causal treatment effects while accounting for the effect of treatment interference. In this article, we view treatment diffusion as a concrete form of…

Research has indicated that early sexual intercourse in high school is associated with poor health outcomes such as unintentional pregnancy and sexually transmitted infections (STIs). What is lacking in the research is an understanding of the relationship between even earlier sexual initiation (i.e., before the age of 13) and alcohol, tobacco, and…

The U.S. Food and Drug Administration (FDA) developed a public education campaign, The Real Cost, that reduced youth susceptibility to tobacco product use. We sought to identify the mechanisms that may underlie the impact of The Real Cost ads on susceptibility to vaping to inform youth tobacco prevention campaigns. Our online randomized controlled…

The current study assessed whether risk factors associated with vaping were distinct from risk factors associated with other substance use (e.g., alcohol, cannabis) during adolescence. Participants (N = 848, ages 10-16 years) completed a self-report survey to assess frequency and age of onset of substance use, risk perceptions of use, risk factors…

Objective: Student loan debt has become a growing crisis. Considering that women are more likely than men to take on student loans and more likely to take on larger amounts, we examine whether the effects of student loans on young adults' mental health and substance use differ by gender. Participants: We used the National Longitudinal Survey of…

Objective: To explore the associations between the consumption of three categories of ultra-processed food (sugary beverages, sweet, and salty snacks) and body mass index (BMI) among Chilean university students.

Telephone-based services are a practical and effective behavioral support for smoking cessation, yet no in-depth analyses of this counseling have been conducted. Understanding the general content of Quitline conversations can help to improve current practices and may inform future interventions. Therefore, we aimed to independently explore…

Substance use in adolescence is a significant public health issue, particularly in early-to-mid adolescence, which represents a window of risk in the etiology of substance abuse and dependence. Substance use during this development period often results from affiliation with deviant peers, who model, facilitate, and reinforce use. Existing…

Objective: Work examining the long-term impact of the COVID-19 pandemic on e-cigarette use among college students is limited. Therefore, the current study examined differences in college student e-cigarette users' changes in use behavior and risk perceptions as the pandemic continues. Participants: 129 undergraduate current e-cigarette users…

Objective: To examine the association between vaping and health behaviors (physical activity, fruit and vegetable consumption, sleep, cigarette use, alcohol consumption) and mental health among college students.
