Objective To evaluate the impact of an online-delivered, theory-based narrative video on cervical cancer screening knowledge, attitudes, and beliefs in a predominantly Latino community. Methods The study design was a nonrandomized pretest–posttest evaluation. The eligibility criteria included men and women 18 years or older not previously enrolled in our community cervical cancer screening program who had internet access. Participants were recruited via in-person county-wide flyer distribution and social media dissemination. The intervention involved a narrative video designed for Latinas delivered via the internet. The 17-minute video is novella style, with a culturally tailored storyline and setting that covers cervical cancer risk factors and statistics, importance of screening, and addresses testing barriers. The measures were knowledge about cervical cancer and screening, perceived susceptibility, perceived seriousness, perceived benefits, perceived barriers, subjective norms, and self-efficacy. Analysis was performed using change scores for knowledge and psychosocial variables and descriptive statistics for satisfaction and acceptability of the video. Results Data from 227 surveys were analyzed; respondent mean age: 37.6 years; 98.8% female, 88.8% Hispanic; 42.0% had an annual income of $20,000 or less; and 85.2% had at least a high school education. Knowledge and all psychosocial variables improved significantly. More than 90% of the participants rated all of the satisfaction items as good or excellent. Conclusions and Implications for Practice A culturally appropriate narrative video about cervical cancer and screening disseminated online effectively improved knowledge and psychosocial variables among Latinas. Our findings indicate that health promotion interventions online could be effective for improving desired health behavior through a new means of educational dissemination by way of websites and social media outlets.
