Teacher attitudes and instructional strategies impact success of human sexuality programs. Limited prior research has examined the relations of teachers’ attitudes and instruction to the development of adolescents’ sexual self-efficacy beliefs. This study examined how adolescents’ perceptions of their health teachers (i.e., teacher value of content, teacher affinity, teacher caring for students) predict changes in efficacy beliefs related to HIV/STD and pregnancy prevention, and if perceptions of mastery goal structure predicted adaptive efficacy beliefs. Data were collected in 4 Midwestern/Appalachian high schools in health class where the delivery of a 14-lesson sexual health curriculum occurred. Participants included 561 students (50.4% 9^th graders, 43.5% female, 56.3% White, 53.7% did not have a current romantic partner, and 59.7% had previously not engaged in sexual activity). The findings indicate students’ perceptions of teachers valuing the content predicted perceptions of mastery goal structure for all sexual self-efficacy beliefs: learning efficacy, condom negotiation efficacy, refusal self-efficacy, and situational self-efficacy. Students who perceive a mastery goal structure in health class, and who feel their teachers value learning about HIV/STD and pregnancy prevention, are likely to experience positive adaptive self-efficacy beliefs related to sexual health, ultimately leading to behaviors indicative of decreased STDs among teenagers and safe sexual practices, such as abstinence, the use of a condom, and saying “no” to having sex.

教师的态度和教学策略会影响人类性项目的成功。有限的先前研究检查了教师的态度和教学与青少年性自我效能信念发展的关系。本研究检查了青少年对其健康教师的看法（即，教师对内容的价值、教师亲和力、教师对学生的关心）如何预测与 HIV/STD 和怀孕预防相关的功效信念的变化，以及对掌握目标结构的看法是否预测适应性效能信念。数据是在 4 所中西部/阿巴拉契亚高中的健康课上收集的，这些学校提供了 14 节课的性健康课程。参与者包括 561 名学生（50.4% 9 ^th年级学生，43.5% 女性，56.3% 白人，53.7% 没有当前的恋人，59.7% 以前没有从事过性活动）。研究结果表明，学生对教师重视内容的看法预测了对所有性自我效能信念的掌握目标结构的看法：学习效能、安全套谈判效能、拒绝自我效能和情境自我效能。在健康课程中感知到掌握目标结构的学生，并且认为他们的老师重视学习 HIV/STD 和怀孕预防的学生，可能会体验到与性健康相关的积极适应性自我效能信念，最终导致表明性病减少的行为青少年和安全的性行为，例如禁欲、使用安全套以及对性行为说“不”。
