本研究开发了青年自我效能（SEPA）和代理效能（PEPA）的措施，体力活动（PA）。代理效能被定义为一个年轻人的信心，他或她的技能和能力，让别人采取行动，在自己的利益，创造支持性的环境PA。在六年级、七年级和八年级的每个春天，中学生们完成SEPA和PEPA问题，然后用3天的时间回忆前一天的课后PA。探索性和验证性因素分析揭示了一个四因素结构（SEPA为1-3天，SEPA为5-7天，PEPA-家长，PEPA-学校）。在整个研究年份中，SEPA 1-3天和5-7天增加，PEPA-父母和PEPA-学校减少。PEPA-父母和SEPA量表的初始水平与PA的初始水平相关。从六年级到七年级，SEPA量表的变化与PA的变化相关。研究应测试针对自我效能和代理效能的干预措施是否会影响PA。
This study developed youth self-efficacy (SEPA) and proxy efficacy (PEPA) measures for physical activity (PA). Proxy efficacy was defined as a youth’s confidence in his or her skills and abilities to get others to act in one’s interests to create supportive environments for PA. Each spring of their sixth-, seventh-, and eighth-grade years, middle school students completed SEPA and PEPA questions and then, for 3 days, recalled their previous day’s after-school PA. Exploratory and confirmatory factor analyses revealed a four-factor structure (SEPA for 1–3 days, SEPA for 5–7 days, PEPA-Parents, PEPA-School). Across study years, SEPA 1–3 days and 5–7 days increased and PEPA-Parents and PEPA-School decreased. Initial levels of PEPA-Parents and SEPA scales were associated with initial levels of PA. From sixth through seventh grade, changes in SEPA scales were associated with changes in PA. Studies should test whether interventions targeting self-efficacy and proxy efficacy influence PA.
