ABSTRACT: INTRODUCTION:Patients' sexual concerns are private, sensitive issues, and providing sexual health care (SHC) is a legitimate area of concern for the nursing practice. AIMS:This study tests a structural equation model for factors that affect SHC among Taiwanese nurses. METHODS:A cross-sectional study was performed between August 2014 and July 2015. A total of 471 registered nurses from a medical center in Taiwan were enrolled in this study. All nurses participated anonymously and completed 3 questionnaires: Nursing Attitude in Sexual Health Care scale, Nursing Intervention in Sexual Health scale, and Gender Role Orientation scale. The Permission-Limited Information-Specific Suggestions-Intensive Therapy model based on scale was application, and theory of planned behavior was used to examine the relationship of these 3 scales in nurses. MAIN OUTCOME MEASURES:SHC surveys were developed for nurses. These valid and reliable instruments included Nursing Attitude in Sexual Health Care, Nursing Intervention in Sexual Health, and Gender Role Orientation. RESULTS:The fitted structural equation model was valid. The construct reliability of latent variables ranged from 0.730 to 0.942, which met the requirement of 0.70. The attitude about SHC (? = 0.182, P < .001), subjective norms on SHC (? = 0.146, P < .001), and confidence about SHC (? = 0.583, P < .001) had significant effects on the behavioral intention to provide SHC. Subsequently, the behavioral intention to provide SHC had a significant, direct effect on the behavioral frequency of providing SHC (? = 0.356, P < .001). However, gender role orientation was not significantly associated with behavioral intention and behavioral frequency to provide SHC. CONCLUSIONS:The good fit for the structural equation model suggests that the predictors of behavioral intention and behaviors of providing SHC include attitude, subjective norms, and perceived control. The stronger behavioral intention of providing SHC resulted in a higher frequency of providing SHC. However, the relationship between gender role orientation and SHC had no significant effect.
