目的：研究TriTrac记录的活动与常用活动测量和相关结构的相关性。方法：TriTrac评分与3个直接自我报告指标、4个间接活动指标和5个通常与活动相关的结构相关。结果：TriTrac和主要标准测量之间存在中度相关性。受试者佩戴TriTrac装置的天数占要求天数的78%，未佩戴TriTrac的时间少报，结论：必须谨慎解读加速度计数据，因为受试者可能会少报未佩戴器械的时间。研究人员应考虑TriTrac器械损坏的可能性。
Objective: To examine the association of TriTrac recorded activity with commonly used measures of activity and associated constructs. Method: TriTrac scores were correlated with 3 direct self-report measures, 4 indirect activity measures, and 5 constructs commonly associated with activity. Results: A moderate correlation was found between TriTrac and the main criterion measure. Subjects wore the TriTrac units 78% of the requested days and underreported time not wearing the TriTrac, Conclusion: Accelerometer data must be interpreted with caution, given that subjects will likely underreport time not wearing the devices. Researchers should provide for the possibility of damaged TriTrac devices.
