The aim of this review was to evaluate the reliability and validity of methods used to assess the multiple components of sedentary behaviour (i.e. screen time, sitting, not moving and existing at low energy expenditure) in children and adolescents. Twenty-six studies met our inclusion criteria and were reviewed. Thirteen studies reported the reliability of self- and proxy-report measures of sedentary behaviour and seven of these were found to have acceptable test-retest reliability. Evidence for the criterion validity of self- and proxy-report measures was examined in three studies with mixed results. Seven studies examined the reliability and/or validity of direct observation and the findings were generally positive. Five studies demonstrated the utility of accelerometers to accurately classify sedentary behaviour. Self-report measures provide reliable estimates of screen time, yet their validity remains largely untested. While accelerometers can accurately classify participants' behaviour as sedentary, they do not provide information about type of sedentary behaviour or context. Studies utilizing measures of sedentary behaviour need to more adequately report on the validity and reliability of the measures used. We recommend the use of objective measures of sedentary behaviour such as accelerometers, in conjunction with subjective measures (e.g. self-report), to assess type and context of behaviour.
本综述的目的是评估用于评估儿童和青少年久坐行为（即屏幕时间、坐姿、不活动和处于低能量消耗状态）多个组成部分的方法的可靠性和有效性。有 26 项研究符合我们的纳入标准并进行了审查。有 13 项研究报告了久坐行为的自我报告和代理报告测量的可靠性，其中 7 项被认为具有可接受的重测可靠性。有 3 项研究检查了自我报告和代理报告测量的标准有效性，结果喜忧参半。有 7 项研究检验了直接观察的可靠性和/或有效性，结果总体上是积极的。有 5 项研究表明加速度计可准确分类久坐行为。自我报告测量可提供可靠的屏幕时间估计值，但它们的有效性仍在很大程度上未经测试。虽然加速度计可以准确地将参与者的行为分类为久坐行为，但它们不能提供关于行为类型或背景的信息。使用久坐行为测量的研究需要更充分地报告所使用的测量的有效性和可靠性。我们建议使用加速度计等客观的久坐行为测量方法，结合主观测量（例如自我报告），以评估行为的类型和背景。
