This study was conducted to develop the Sexually Transmitted Infections (STI) Knowledge Scale for adolescents. Based on a literature review, the first preliminary 40 questions were created, which content validation by expert reviewers and a pilot study then refined into a draft scale of 29 items. To confirm the validity and reliability of this preliminary scale, data were collected from 141 adolescents between February 13 and 26, 2016: factor analysis resulted in a factor loading of more than .52, while convergent validity revealed that the group receiving STI education was significantly higher (p=.009). The final version of the scale contained 16 items, with a reliability measured by Cronbach's ${\alpha}$ of .85 and the 39.3% of correct answers. The STI knowledge scale developed in this study is a valid scale that can be used to evaluate the effectiveness of STI education for adolescents.

Although the need for education on sexually-transmitted-infections (STIs) for adolescents has been increasing, a limited number of adolescents receive STI education. Importantly, the exposure of youth to an STI during their adolescence period can seriously affect their genital health. Smartphones are an innovative medium that can be used to change individual behaviors, especially useful when used to educate adolescents. Therefore, we developed a customized smartphone application for Korean adolescents. The application was based on Dick and Carey's instructional system design model. In this paper, we describe the process for development of the smartphone application, and the strategies we applied to attract adolescents to use the smartphone application. Six experts verified the educational content of the application. The application's easygoing words were chosen to help adolescents understand the topic. Strategies such as cartoon clips, secret chat rooms, buttons changing color from blue to grey, questions and answers, and a repeated-learning function were used to attract Korean adolescents to the application. The smartphone application developed in this study could be used in schools, youth centers, and hospital centers to improve STI knowledge, STI prevention, and STI coping skills.
