The overall objective of the proposed research is to reduce the incidence of sexually transmitted infections (STIs) among college students. The investigators propose to accomplish this by using the innovative, engineering-inspired multiphase optimization strategy (MOST) to develop a highly effective, appealing, economical, and readily scalable internet-delivered behavioral intervention targeting the intersection of alcohol use and sexual risk behavior. The rate of STIs on college campuses is alarming: one in four college students is diagnosed with an STI at least once during their college experience. Sexual activity when drinking alcohol is highly prevalent among college students. Alcohol use is known to contribute to the sexual risk behaviors that are most responsible for the transmission of STIs, namely unprotected sex, contact with numerous partners, and "hook-ups" (casual sexual encounters). Few interventions have been developed that explicitly target the intersection of alcohol use and sexual risk behaviors, and none have been optimized. In order to reduce the incidence of STI transmission among this and other high-risk groups, a new approach is needed. MOST is a comprehensive methodological framework that brings the power of engineering principles to bear on optimization of behavioral interventions. MOST enables researchers to experimentally test the individual components in an intervention to determine their effectiveness, indicating which components need to be revised and re-tested. Given the high rates of alcohol use and sex among college students, the college setting provides an ideal opportunity for intervening on alcohol use and sexual risk behaviors. The proposed study will include a diverse population of college students on 4 campuses which will increase the generalizability of the findings. The specific aims are to (1) develop and pilot test an initial set of online intervention components targeting the link between alcohol use and sexual risk behaviors, (2) use the MOST approach to build an optimized preventive intervention, and (3) evaluate the effectiveness of the newly optimized preventive intervention using a fully powered randomized controlled trial (RCT). This work will result in a new, more potent behavioral intervention that will reduce the incidence of STIs among college students in the US, and will lay the groundwork for a new generation of highly effective STI prevention interventions aimed at other subpopulations at risk.

---|---|---|---|---|
Primary | Descriptive norms about the intersection of alcohol and sex collected via an online questionnaire. | This scale consists of 6 items and will be created as a weighted scale score. Analyses will report the mean and standard deviation and expected mean values from a regression analysis. The scale will reflect the average perceived prevalence of the alcohol and sex behaviors. | This measure will be assessed immediately following the 3-week intervention. | |
Primary | Injunctive norms about the intersection of alcohol and sex collected via an online questionnaire. | This scale consists of 6 items and will be created as a weighted scale score. Analyses will report the mean and standard deviation and expected mean values from a regression analysis. The scale will reflect the average perceived approval of the alcohol and sex behaviors, ranging from strongly disapprove to strongly approve. | his measure will be assessed immediately following the 3-week intervention. | |
Primary | Expectancies about the intersection of alcohol use and sex collected via an online questionnaire. | This scale consists of 10 items and will be created as a weighted scale score. Analyses will report the mean and standard deviation and expected mean values from a regression analysis. The scale will reflect the average number of drinks expected to experience the 10 different outcomes. | This measure will be assessed immediately following the 3-week intervention. | |
Primary | Perceived benefits about using protective behavioral strategies collected via an online questionnaire. | This scale consists of 11 items and will be created as a weighted scale score. Analyses will report the mean and standard deviation and expected mean values from a regression analysis. The scale will reflect the average likelihood of contracting an STI using the listed behaviors. | This measure will be assessed immediately following the 3-week intervention. | |
Primary | Self-efficacy to use protective behavioral strategies collected via an online questionnaire. | This scale consists of 9 items and will be created as a weighted scale score. Analyses will report the mean and standard deviation and expected mean values from a regression analysis. The scale will reflect the average level of confidence is using protective behavioral strategies to reduce the risk of contracting and STI, ranging from not at all confident to extremely confident. | This measure will be assessed immediately following the 3-week intervention. | |
Secondary | Binge drinking behavior collected via an online questionnaire. | This item asks how many times in the past two weeks a male has 5 or more drinks in a 2-hour period (or females 4 or more drinks in a 2-hour period). This variable will be collapsed into 1 or more times versus other and reported as a prevalence of this behavior and used as a dichotomous outcome in regression analyses. | This measure will be assessed 1 month following the completion of the intervention. | |
Secondary | Unprotected sex behavior at most recent sex collected via an online questionnaire. | This item asks whether or not a condom was used for oral, anal or vaginal sex. This variable will be collapsed into a dichotomous variable with unprotected anal or vaginal sex versus other and reported as a prevalence of this behavior and used as a dichotomous outcome in regression analyses. | This measure will be assessed 1 month following the completion of the intervention. | |
Secondary | Penetrative sex at most recent hookup collected via an online questionnaire. | This item asks whether or not the most recent hookup included vaginal or anal sex. This variable will be collapsed into a dichotomous variable with penetrative sex versus other and reported as a prevalence of this behavior and used as a dichotomous outcome in regression analyses. | This measure will be assessed 1 month following the completion of the intervention. |
