目前的研究考察了代理效力，它被定义为年轻人影响父母提供水果和蔬菜的信心。总体目标是考察中学青年代理效能随时间的变化，并确定变化是否受到性别和社会经济地位的调节。纵向队列嵌套在学校。位于美国中西部一个州的城市、郊区和农村地区的八所中学。在6年级、7年级和8年级对712名青少年进行了跟踪调查。样本中51.8%为女性，30.5%为低社会经济地位，89.5%为白种人，非西班牙裔。在每个评估年，男性和低社会经济地位青年的代理效力分别显著低于女性和高社会经济地位青年。影响父母提供水果和蔬菜的代理效力可能是未来干预措施的重要目标。
The current study examined proxy efficacy, which was defined as youth’s confidence to influence their parents to provide fruits and vegetables. The overall objective was to examine change in middle-school youth’s proxy efficacy over time, and to determine if changes were moderated by gender and socio-economic status. Longitudinal cohort nested within schools. Eight middle schools located in urban, suburban and rural areas of a mid-western US state. Seven hundred and twelve youth followed across their 6th, 7th and 8th grade years. The sample was 51·8% female, 30·5% low socio-economic status and 89·5% Caucasian, non-Hispanic. Males and lower socio-economic status youth were significantly lower in proxy efficacy at each assessment year compared with females and high socio-economic youth, respectively. Proxy efficacy to influence parents to provide fruits and vegetables may be an important construct to target in future interventions.
