About this study
Official title: The Effects of a Digital Serious Game Intervention on Sexual Knowledge, Sexual Consent, and Safer Sex Behaviors Among Emerging Adult Males
Sexual health among young people is an important issue for healthcare professionals, educators, and society. The purpose of this study was to examine the effects of a mobile application on emerging adult men's sexual knowledge, sexual consent, and safer sexual behavior outcomes. A total of 174 emerging adult men were recruited through purposive sampling between November 2022 and July 2023, with 75 in the experimental group and 99 in the control group. Data were collected at three time points: baseline, immediately after the 6-week intervention, and 4 weeks after the intervention ended. The findings showed that the intervention significantly increased sexual knowledge, improved positive attitudes toward sexual consent, and reduced assumptions of consent. It also increased behavioral intentions regarding condom use among participants in committed relationships and improved attitudes toward condom use with casual partners.
Read the detailed description
Sexual health among young people is an important issue for healthcare professionals, educators, and society. Conversations about sexual health are often sensitive and uncomfortable for young people. This is especially true for young men, who may face peer pressure and misconceptions about sexual consent and safer sexual practices. Promoting an accurate understanding of mutual consent and responsible sexual behaviors among young men is therefore crucial. To address this need, we developed a sexual health program delivered through a mobile application.

A total of 174 emerging adult men were recruited through purposive sampling between November 2022 and July 2023, with 75 in the experimental group and 99 in the control group. The experimental group received the mobile application intervention, while the control group received routine care. Data were collected at three time points: baseline, immediately after the 6-week intervention, and 4 weeks after the intervention ended.
The findings showed that the intervention significantly increased sexual knowledge, enhanced positive attitudes toward sexual consent, and reduced assumptions of consent. It also increased behavioral intentions regarding condom use among participants in committed relationships and improved attitudes toward condom use with casual partners. Overall, the intervention was perceived as a practical and innovative approach to equipping young men with essential self-protection and respectful communication skills.

What is being measured
The primary outcome is the main question the study is designed to answer.
Sexual knowledge
The Adolescent Sexual Knowledge Scale, developed by the Hsing-Ling Medical Foundation, was used to assess sexual knowledge among college students. The scale consists of 12 true-or-false items covering two dimensions: pregnancy and contraception, and prevention of human immunodeficiency virus infection, acquired immunodeficiency syndrome, and other sexually transmitted infections. For the pregnancy and contraception dimension, item difficulty ranged from 0.44 to 0.48, and item discrimination exceeded 0.80. For the dimension concerning prevention of human immunodeficiency virus infection, acquired immunodeficiency syndrome, and other sexually transmitted infections, item difficulty ranged from 0.39 to 0.48, and item discrimination exceeded 0.80. These results indicate good item discrimination across the scale.
Measured: Time Frame: baseline , immediately after the 6-week intervention, and 4 weeks post-intervention
Sexual Consent
The Sexual Consent Scale-Revised, which is based on the theory of planned behavior, includes five subscales: perceived behavioral control (11 items; Cronbach's alpha = .86), positive attitudes toward establishing consent (11 items; Cronbach's alpha = .84), indirect consent behaviors (6 items; Cronbach's alpha = .78), sexual consent norms (7 items; Cronbach's alpha = .67), and sexual consent awareness (4 items; Cronbach's alpha = .71). The scale consists of 39 items, each rated on a seven-point scale ranging from 1 (strongly disagree) to 7 (strongly agree). Higher scores indicate more positive attitudes toward and greater endorsement of sexual consent and negotiation behaviors in intimate relationships with heterosexual partners.
Measured: Time Frame: baseline , immediately after the 6-week intervention, and 4 weeks post-intervention
Safer sex
The Safer Sexual Behavior Scale was used to assess variables from the theory of planned behavior, including attitudes, subjective norms, perceived behavioral control, behavioral intentions, and behaviors, across four sexual behaviors. The scale consists of 60 items, each scored from 1 to 7. Three of the four sexual behaviors concern the use of contraception, condoms, and dual protection during sexual intercourse with an intimate partner, with higher scores indicating greater endorsement of safer sexual behaviors. The fourth concerns sexual intercourse with a casual partner, with higher scores indicating greater endorsement of casual sexual intercourse. Cronbach's alpha coefficients for the Chinese version ranged from .71 to .97.
Measured: Time Frame: baseline , immediately after the 6-week intervention, and 4 weeks post-intervention
