Although physical activity (PA) interventions have been effective for improving health outcomes in breast cancer survivors, little is known relative to their potential for translation into practice.
This review was designed to provide a quantitative estimate of the reporting of both internal and external validity in recent studies of PA in breast cancer survivors (BCS).
The Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was utilized to assess the reporting of internal and external validity in 25 randomized controlled trials (RCTs) of PA and BCS published between 1998 and 2008. Each trial was evaluated relative to the degree it met criteria for each of the above dimensions.
The majority of studies in this review reported dimensions reflecting internal validity. The overall level of detail relative to external validity of PA interventions was rarely reported, limiting the generalizability of study findings.
As with many RCTs of health behavior change, detail relative to contextual elements of published PA interventions in BCS is limited. It is recommended that future physical activity interventions in BCS be designed to facilitate scalable and sustainable interventions for improving health outcomes in this population.
尽管体育活动（PA）干预措施在改善乳腺癌幸存者的健康结局方面已被证明有效，但对于其转化为实际应用的潜力却知之甚少。
本综述旨在对近期乳腺癌幸存者（BCS）体育活动研究中内部效度和外部效度的报告情况进行定量评估。
采用“可及性、效果/有效性、采用、实施和维持”（RE-AIM）框架，评估1998年至2008年间发表的25项PA与BCS随机对照试验（RCT）中内部效度和外部效度的报告情况。每项试验根据其符合上述各维度标准的程度进行评估。
本综述中的大多数研究报告了反映内部效度的维度。关于PA干预措施外部效度的总体细节水平很少被报告，这限制了研究结果的可推广性。
与许多健康行为改变的随机对照试验一样，已发表的BCS体育活动干预措施中与背景因素相关的细节有限。建议未来针对BCS的体育活动干预措施应设计为便于扩大规模和持续实施，以改善该人群的健康结局。
