Physical activity (PA) levels are low in patients with lung cancer. Emerging evidence supports the use of interventions to increase PA in this population. We aimed to (1) identify and synthesize outcome measures which assess PA levels in patients with lung cancer and (2) to evaluate, synthesize and compare the psychometric properties of these measures. A systematic review of articles from searches was conducted of five electronic databases and personal records. Eligible studies were those which assessed PA using either performance-based or patient-reported measures. For aim 2, studies identified in aim 1 reporting on at least one psychometric property (validity, reliability, responsiveness or measurement error) were included. Two independent reviewers assessed eligibility and risk of bias with the COnsensus-based Standards for the selection of health status Measurement INstruments. Thirty-four studies using 21 different measures of PA were identified. Seventeen studies used performance-based measures. The Godin Leisure Time Exercise Questionnaire (GLTEQ) was the most frequently used patient-reported measure. Psychometric properties were reported for 13 of these measures and most frequently for movement sensors. Two studies reported on properties of the GLTEQ. Quality ratings for risk of bias were low. There is significant heterogeneity amongst studies regarding method of PA measurement along the lung cancer continuum. Greater consensus could be achieved by using a consensus approach such as a Delphi process. Future studies should include assessment of psychometric properties of the measurement tool being used. Currently, it is recommended where feasible, both performance-based and patient-reported measurements of PA should be undertaken.
体力活动（PA）水平在肺癌患者中较低。新出现的证据支持在该人群中使用干预措施来增加体力活动。我们的目的是：（1）确定并综合评估肺癌患者体力活动水平的结果测量指标；（2）评估、综合和比较这些测量指标的心理测量学特性。对来自五个电子数据库和个人记录的文章进行了系统的检索。符合条件的研究是指使用基于表现或患者报告的测量方法评估体力活动的研究。在目标 2 中，纳入了在目标 1 中确定的报告了至少一项心理测量学特性（有效性、可靠性、反应度或测量误差）的研究。两名独立的审查员使用共识标准评估了入选健康状况测量工具的一致性。共确定了 34 项使用 21 种不同体力活动测量指标的研究。17 项研究使用了基于表现的测量方法。Godin 休闲时间运动问卷（GLTEQ）是最常用的患者报告测量指标。其中 13 项测量指标报告了心理测量学特性，而运动传感器的特性报告最为常见。有两项研究报告了 GLTEQ 的特性。对偏倚风险的质量评分较低。在肺癌连续体中，体力活动的测量方法存在很大的异质性。通过使用共识方法（如 Delphi 过程）可以达成更大的共识。未来的研究应包括对所使用的测量工具的心理测量学特性进行评估。目前，建议在可行的情况下，同时进行基于表现和患者报告的体力活动测量。
