Only very few instruments have been developed to assess sexual knowledge and practices. Most of the research to date has been carried out with adolescent samples, but not with university students, who are also at a particularly risky stage. The aim of this study was to design and validate a brief questionnaire to assess young´s sexual knowledge, practices and behaviors to design health education programs in the university context.
We created a specific questionnaire about sexual pattern in university adolescents and a brief questionnaire consisted of 9 items (true/false) about contraception, sexuality and sexual transmission diseases. We carried out a pilot study, reliability (KR-20) and validity analyses using factorial analysis and examining the association with other variables.
566 students from University of Seville participated during 2015/16. One item was eliminated because of comprehension (only 13.9% of correct answers) and weak or non significant associations (p more than 0.05). Finally, the scale was formed by 8 items and had good internal consistency reliability (KR-20 = 0.57), and both factorial and external validity reliability. A three-factor model showed good data fit, χ2 (14, N=566)=17.48, p= 0.232, Comparative Fit Index CFI = 0.97, root mean squared error of prediction RMSEA = 0.02. Participants with less knowledge about sexuality were whose did not receive any information (M=6.82, SD=1.41), without partner (M=6.87, SD=1.35), had an abortion (M=6.43, SD=1.95) and did not use any contraceptive method (M=6.66, SD=0.58) or coitus interruptus (M=6.55, SD=1.39), and had less sexual relationships, e.g., once or twice a year (M=6.49, SD=1.70).
This questionnaire is a short instrument to assess students´ practices and knowledge about sexuality and contraception. The analyses of reliability and validity have shown the good psychometric properties of this instrument.
目前仅开发了极少数用于评估性知识和性行为的工具。迄今为止，大多数研究是针对青少年样本进行的，而非针对同样处于特别危险阶段的大学生。本研究的目的是设计并验证一份简短问卷，以评估年轻人的性知识、性行为和性相关行为，从而在大学环境中设计健康教育项目。
我们创建了一份关于大学青少年性模式的特定问卷，以及一份由9个关于避孕、性和性传播疾病的是非题组成的简短问卷。我们进行了一项预试验研究，使用因子分析并检验与其他变量的关联进行信度（KR-20）和效度分析。
2015/16学年期间，来自塞维利亚大学的566名学生参与了研究。由于理解问题（正确答案仅占13.9%）以及关联较弱或不显著（p大于0.05），一个项目被剔除。最终，该量表由8个项目组成，具有良好的内部一致性信度（KR-20 = 0.57），以及因子效度和外部效度。一个三因素模型显示出良好的数据拟合度，χ2（14，N = 566）= 17.48，p = 0.232，比较拟合指数CFI = 0.97，预测均方根误差RMSEA = 0.02。对性知识了解较少的参与者包括那些未接受任何性信息的人（M = 6.82，标准差 = 1.41）、没有性伴侣的人（M = 6.87，标准差 = 1.35）、有过堕胎经历的人（M = 6.43，标准差 = 1.95）、未使用任何避孕方法的人（M = 6.66，标准差 = 0.58）或采用体外射精的人（M = 6.55，标准差 = 1.39），以及性伴侣较少的人，例如每年一两次（M = 6.49，标准差 = 1.70）。
这份问卷是一种用于评估学生性实践和性与避孕知识的简短工具。信度和效度分析表明该工具具有良好的心理测量特性。
