The purposes of this study were 1) to investigate current nursing practice related to the sexual assault victims in Taiwan, and 2) to find out the predicting factors of a nurse being successful as a sexual assault nurse examiner. A confidential survey data (n=554) were collected from 59 responsibility hospital for sexual assault. The valid questionnaires were 463 with 69.7% effective returned rate. Result: Majority of the nurses participated in the study (n=463) have the average working experience of 7.7 years. Factor Analysis was carried out to test the factor structure of sexual assault nursing services in Taiwan on 6 main dimensions of victim support and health education, providing information and referral follow-up care, collecting physical evidence, drug screen, completing documentation and maintaining chain-of-evidence, and screening for evidence of sexual contact. The results, using multiple regression analysis, revealed the predictors of being a successful nurse in the area of sexual assault were the nurses’ perceived techniques for blood drawing, good nursing education train, techniques for urine screen, good training of forensic principles, and availability of explaining the protocol process for victim. The total variance explained was 29.5 percent. The results showed that respondents with more experience about medical-legal exams presented more independent ability to perform sexual assault examinations. However, nursing practice is limited because of the medical care act and lack of forensic nurse examiner training program in Taiwan.
