A mobile-based educational intervention on STI-related preventive behavior among Iranian women.

While rates of sexually transmitted infections (STIs) in Iran are alarming, little is known about preventive sexual behaviors. The purpose of this article was to assess the effect of a mobile-based educational program to promote preventive behaviors regarding STIs in Iranian women. Using Roger's protection motivation theory, the following measures were developed as the study's conceptual framework: STI knowledge, STI vulnerability, STI prevention self-efficacy and STI prevention intentions. These variables were measured by the Persian version of a valid Korean four-scale tool. Data from 76 women were analyzed: 37 women in the smartphone application (Experimental) group and 39 in the control group. Health Education Sexually Transmitted Infections Application was developed as a smartphone application training program. Participants were tested at three-time points: pre-test (baseline), post-test 1 (immediately after the program's completion) and post-test 2 (16 weeks after the program's completion). Significant group differences were found at different times in STI knowledge, vulnerability, prevention self-efficacy and prevention intentions. The smartphone application was effective in sustaining the effects of the educational program in the experimental group. The development of appropriate teaching materials on sensitive public health issues, such as STIs to promote individual self-learning skills is suggested. � The Author(s) 2021.
