The Impact of Knowledge, Self-efficacy, and Stigma on STI Testing Intention among College Students

Young people (ages 15-24) account for over half of the new cases of sexually transmitted infections (STIs) each year in the United States (CDC, 2016). The current study examined how knowledge, self-efficacy, and stigma are associated with STI testing intention among sexually active college students using path model analysis. Data were collected via an online survey (N = 76, 54% female). STI testing intention was measured using a 5-point Likert scale for eight STIs referenced in the Brief Sexual History Tool (CDC, 2018). These items comprised an intention scale with high internal consistency for this sample (α = .97). Path analysis was conducted using SPSS AMOS and MacKinnon’s ab product approach in RMediation was used to test mediating effects. The predicted path model fit the data well and the relationships between self-efficacy and knowledge, label avoidance, and intention were significant. Mediation analysis revealed significant indirect paths for knowledge and label avoidance on STI testing intention through self-efficacy. These findings indicate that self-efficacy directly impacts college students’ STI testing intention, while knowledge and label avoidance indirectly impact intention through self-efficacy. Findings suggest that providers and college health clinics may be able to increase the frequency of STI testing behavior by promoting strategies to increase students’ self-efficacy
