需要对日本成年人的久坐行为进行高质量的测量，以准确评估特定久坐行为的相关性。本研究评估了总久坐行为的效标效度和六个特定领域久坐行为的重测信度。我们根据以前的研究进行了一份问卷调查，测量特定领域的久坐行为。为了检验有效性，在两个日本城市的392名成年人（40-64岁）中，比较了问卷中自我报告的久坐行为时间与使用加速度计客观测量的久坐时间之间的一致性。为了确保可靠性，对34名参与者进行了为期2周的间隔重测。自我报告的总久坐时间与客观测量的久坐时间之间的相关性在工作日（ρ = 0.57）和整个星期（ρ = 0.49）是显著的（均P < 0.001）和一般至良好，但在非工作日（ρ = 0.23）是低的。两项指标之间的差异在全周（=-2.25，P = 0.03）和非工作日（=-5.50，P < 0.001）有显著性，但在工作日（=-0.60，P = 0.55）没有显著性。两项指标的差异与两项指标的平均值之间存在显著正相关（工作日：r = 0.53;非工作日：r = 0.45;全周：r = 0.54，均P < 0.001）。各领域的总久坐时间的重测信度均为良好（工作日：组间相关系数[ICC] = 0.77，非工作日：ICC = 0.53，整周：ICC = 0.7;均P < 0.01）。特定领域的久坐行为的规模是可靠的估计在哪里和出于什么目的，日本成年人花费他们的久坐时间，和总久坐时间是有效的工作日和整个星期。
Good quality measures of Japanese adults’ sedentary behaviors are needed to accurately assess correlates of specific sedentary behaviors. The present study assessed criterion validity of total sedentary behavior and test-retest reliability of six domain-specific sedentary behaviors. We administered a questionnaire, based on previous studies, that measured domain-specific sedentary behaviors. To examine validity, agreement between self-reported time spent in sedentary behaviors from the questionnaire and objectively-measured sedentary time using accelerometers was compared among 392 adults (aged 40–64 years) in two Japanese cities. For reliability, a 2-week interval test-retest was administered to a convenience sample of 34 participants. The correlation between total self-reported and objectively measured sedentary time was significant (all P < 0.001) and fair-to-good for workdays (ρ = 0.57) and whole week (ρ = 0.49), but was low for non-workdays (ρ = 0.23). The difference between the two measures was significant for whole week ( = −2.25, P = 0.03) and non-workdays ( = −5.50, P < 0.001), but was not significant for workdays ( = −0.60, P = 0.55). There was a significant positive association between the difference in the two measures and the average of these two measures (workdays: r = 0.53; non-workdays: r = 0.45; and whole week: r = 0.54, all P < 0.001). There was fair-to-good test-retest reliability of total sedentary time for each domain (workdays: interclass correlation coefficient [ICC] = 0.77, non-workdays: ICC = 0.53, and whole week: ICC = 0.7; all P < 0.01). The scale of domain-specific sedentary behaviors is reliable for estimating where and for what purpose Japanese adults spend their sedentary time, and total sedentary time is valid for workdays and the whole week.
