Dual method use among a sample of first-year college women.

Context: Dual method use-using one protective method to reduce the risk of STDs and another to prevent pregnancy-is effective but understudied. No prior studies have employed an event-level approach to examining characteristics associated with dual method use among college women.

Methods: In 12 consecutive monthly surveys conducted in 2009-2010, data on 1,843 vaginal intercourse events were collected from 296 first-year college women.

Female College Students' Media Use and Academic Outcomes: Results from a Longitudinal Cohort Study.

This longitudinal study describes women's media use during their first year of college and examines associations between media use and academic outcomes. Female students ( = 483, = 18.1 years) reported on their use of 11 media forms and their grade point average, academic behaviors, academic confidence, and problems affecting schoolwork.

Sexual hookups and adverse health outcomes: a longitudinal study of first-year college women.

"Hookups" are sexual encounters between partners who are not in a romantic relationship and do not expect commitment. We examined the associations between sexual hookup behavior and depression, sexual victimization (SV), and sexually transmitted infections (STIs) among first-year college women. In this longitudinal study, 483 women completed 13 monthly surveys assessing oral and vaginal sex with hookup and romantic partners, depression, SV, and self-reported STIs.

Do alcohol and marijuana use decrease the probability of condom use for college women?

Alcohol and marijuana use are thought to increase sexual risk taking, but event-level studies conflict in their findings and often depend on reports from a limited number of people or on a limited number of sexual events per person. With event-level data from 1,856 sexual intercourse events provided by 297 college women (M age = 18 years; 71% White), we used multilevel modeling to examine associations between alcohol and marijuana use and condom use as well as interactions involving sexual partner type and alcohol-sexual risk expectancies. Controlling for alternative contraception use, partner type, regular levels of substance use, impulsivity and sensation seeking, and demographics, women were no more or less likely to use condoms during events involving drinking or heavy episodic drinking than during those without drinking.

Hookah, cigarette, and marijuana use: a prospective study of smoking behaviors among first-year college women.

Better understanding of the temporal sequence of hookah, cigarette, and marijuana use will help to inform smoking prevention efforts. To address this gap in the literature, we assessed all three of these smoking behaviors in a sample of 424 first-year college women. Using a longitudinal design, we investigated whether hookah use predicts initiating/resuming cigarette and/or initiating marijuana use, and whether cigarette and/or marijuana use predicts initiating hookah use.
