This study evaluated physical activity Web sites to determine quality, accuracy, and consistency with principles of the extended parallel process model (EPPM). Three keyword searches were conducted using 4 search engines to find a sample of N = 41 Web sites. Three raters evaluated the Web sites using the JAMA benchmarks to assess quality and American College of Sports Medicine and Centers for Disease Control and Prevention recommendations for physical activity to determine accuracy, as well as checking for inclusion of EPPM variables. Data were analyzed using descriptive statistics and analysis of variance with least squares means. Only 22% of the sites were high quality, none were highly accurate, and most were consistent with the EPPM. Quality ratings were weakly associated with accuracy. Educational and .net sites were rated significantly higher in quality and accuracy, and government sites were most consistent with the EPPM. Quality Web sites were more often found by using Yahoo and Google. "Exercise" yielded more accurate results, whereas "physical activity" and "fitness" produced more Web sites consistent with the EPPM. It is encouraging that most sites incorporated EPPM concepts; however, quality and accuracy were poor, leaving physical activity information seekers at risk for disease and injury.
本研究对体育活动相关网站进行了评估，以确定其质量、准确性以及与扩展平行过程模型（EPPM）原则的一致性。使用4个搜索引擎进行了三次关键词搜索，以找到一个包含N = 41个网站的样本。三位评估者使用《美国医学会杂志》基准评估网站质量，并依据美国运动医学学院和疾病控制与预防中心的体育活动建议来确定准确性，同时检查是否包含EPPM变量。数据采用描述性统计和最小二乘法均值方差分析进行分析。只有22%的网站质量高，没有一个高度准确，且大多数与EPPM一致。质量评级与准确性的关联较弱。教育类网站和.net网站在质量和准确性方面的评分显著更高，而政府网站与EPPM最为一致。使用雅虎和谷歌更常找到高质量网站。“锻炼”产生的结果更准确，而“体育活动”和“健身”产生的与EPPM一致的网站更多。令人鼓舞的是，大多数网站纳入了EPPM概念；然而，质量和准确性较差，使寻求体育活动信息的人面临疾病和受伤风险。
