Lack of physical activity has contributed to the nation's childhood obesity crisis, but the impact of physical activity on self-efficacy as a mediator of behavior change has not been examined. This systematic review (SR) describes the published evidence related to the impact of physical activity intervention programs on self-efficacy among youths. From January 2000 to June 2011, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards were used to identify publications from PubMed, PsychInfo, Web of Knowledge, and the Cochran Database of Systematic Reviews. The Cochrane Population, Intervention, Control, Outcome, Study Design (PICOS) approach guided this SR articles selection and evaluation process. Of the 102 publications screened, 10 original studies matched the SR inclusion criteria. The types of physical activity interventions and self-efficacy assessments for these 10 studies were diverse. Of the 10 included articles, 6 articles identified an improvement in post-self-efficacy assessments compared to baseline and 4 showed no effect. In conclusion, physical activity intervention programs may improve self-efficacy in youths. A standardized approach to classify and measure self-efficacy is required. Further research is needed to quantify the association of self-efficacy ratings after completing physical activity interventions with objective health improvements, such as weight loss.
缺乏体育活动导致了该国儿童肥胖危机，但体育活动作为行为改变中介对自我效能感的影响尚未得到研究。本系统评价（SR）描述了已发表的与体育活动干预项目对青少年自我效能感影响相关的证据。2000年1月至2011年6月，采用系统评价和Meta分析的首选报告项目（PRISMA）标准，从PubMed、PsychInfo、Web of Knowledge和Cochrane系统评价数据库中识别出版物。Cochrane人群、干预、对照、结局、研究设计（PICOS）方法指导了本系统评价文章的选择和评估过程。在筛选的102篇出版物中，有10项原始研究符合系统评价纳入标准。这10项研究的体育活动干预类型和自我效能感评估各不相同。在纳入的10篇文章中，6篇文章指出自我效能感评估后较基线有所改善，4篇文章显示无效果。总之，体育活动干预项目可能会提高青少年的自我效能感。需要一种标准化的方法来分类和测量自我效能感。还需要进一步研究，以量化完成体育活动干预后自我效能感评分与体重减轻等客观健康改善之间的关联。
