dc.description.abstract The Theory of Planned Behavior (TPB) has been used to predict several health behaviors. Significant prior research has extensively applied the theory to predicting condom usage as an STI preventative behavior. The present study sought to extend the theory to manipulate intention to engage in another preventative behavior: sexually transmitted infection (STI) screening. Subjects were recruited from a small liberal arts college campus. Self-report data examining the central components of the TPB model including attitudes, subjective norms, perceived behavior control, and intention to get screened were collected from 405 students at baseline. Students were then exposed to a month-long campus wide sexual health outreach campaign consisting of a series of posters, placed in highly trafficked areas. Posters contained messages targeting normative beliefs and subjective norms pertaining to STI screening. From the initial sample, 189 students completed post intervention measures.. Full within-subjects analyses were run for just a portion of those students (N = 67) for whom Time 2 data could be matched with Time 1. The intervention increased knowledge that STIs can be asymptomatic, but was found to have no significant effect on attitudes, subjective norms, perceived behavior control, or intention to get screened. Attitudes were found to significantly predict intention at time one, where subjective norms significantly predicted intention post intervention. Consistent with the model, attitudes, subjective norms, and perceived behavior control all related significantly with intention following the intervention (r = .356, r = .443, and r = .249, respectively). Implications for future studies with larger samples and longer exposure intervals are discussed.
