Aim: To examine female youth's intentions for safe sex with the relationship partners based on the extended theory of planned behaviour (TPB) model and explore the direct and indirect impact of parent-child communication about sex, peer interaction related to sexual issues, and exposure to sexually explicit materials on female youth's safe sexual behaviour intentions.

Design: A non-experimental, cross-sectional research design.

Methods: A convenience sampling was employed for data collection and 731 female youth aged 15-24 years old were recruited in 2013-2014. An anonymous, self-report structured questionnaire was used as a research instrument to collect participants' basic information and measure the internal and additional variables in the extended TPB model.

Results: The extended TPB model explained 42-45% of the total variance. Perceived behavioural control (PBC) and subjective norms had a positive effect on female youth's intentions for contraceptive use, condom use, and dual use with relationship partner; PBC was found to have the greatest influence. Among the additional variables in the extended TPB model, more parent-child communication about sex was found to lead to more positive dual use intentions. More peer interaction related to sexual issues was found to lead to less dual use intentions.

Conclusions: To improve female youth's sexual health, the priorities are to reinforce their PBC and subjective norms and enhance parent-child communication about sex. Future efforts should strengthen sex education in families and schools and shape a social environment that facilitates safe sex.

Impact: The extended TPB model can successfully predict female youth's safe sexual behaviour intentions. Empowering female youth to establish a sense of subjectivity and awareness of being a mature individual with physical autonomy, is importance for their sexual health.

目的: 根据扩展计划行为理论(TPB)模型,研究青年女性与伴侣进行安全性行为的倾向,并探讨父母与子女就性行为和与性话题相关的同伴互动的沟通的直接和间接影响,以及接触色情材料对青年女性安全性行为倾向的直接和间接影响。 设计: 非实验性横向研究设计。 方法: 采用方便抽样方法进行数据收集,2013年至2014年共招募了731名15-24岁的青年女性。采用匿名、自我报告结构化问卷作为调研工具,收集参与者的基本信息,并测量扩展计划行为理论模型中的内部变量和附加变量。 结果: 扩展计划行为理论模型解释说明了总方差的42-45%。感知行为控制(PBC)和主观规范对青年女性服用避孕药、使用避孕套、与伴侣采取双重避孕措施的倾向有正向影响,且感知行为控制的影响最大。在扩展计划行为理论模型的附加变量中,我们发现,父母与子女之间进行更多的性行为沟通对采取双重避孕措施的倾向具有积极影响。而更多的有关性话题的同伴互动对采取双重避孕措施的倾向影响较低。 结论: 为改善青年女性的性健康水平,重点在于加强她们的感知行为控制和主观规范,增加父母与子女之间有关性行为的沟通交流。今后应加强家庭和学校的性教育,形成有利于安全性行为的社会环境。 影响: 扩展计划行为理论模型可成功预测青年女性的安全性行为倾向。帮助青年女性建立主体性意识以及掌握身体自主性的成熟个体意识,对其性健康具有重要意义。.
