- Abstract
Introduction: The aim of current study was to develop a questionnaire with good reliability and validity for measuring Taiwanese adolescents' total and domain-specific time spent engaging in various sedentary behaviors. Methods: Ninety-seven junior high school students in Changhua City participated in this study. They completed the questionnaire twice over a one-week period and wore a tri-axial accelerometer during this period. The test-retest reliability was examined by Spearman's rank correlation and paired-samples t-test. The criterion-related validity in total sedentary time per day was first examined by Spearman's rank correlation between self-report measurement and accelerometer-assessed measurement. In addition, a Bland-Altman Plot was used to compare the consistency between these two measurements. Results: The results showed that the mean self-reported total sedentary time was 6.11 (SD = 2.98) hours. With regard to the test-retest reliability, there was no significant difference in total and domain specific time of self-report sedentary behavior, except for "Studying/Doing homework." The Spearman's rank correlation coefficients of the total sedentary time per day, and the two domain specific items, "Using a computer for fun" and "Playing/practicing a musical instrument," were higher than the recommended level 0.70. The coefficients of the other five items, "Using the phone," "Out-of-school-hours tutoring," "Reading for fun," "Passive transport," and "Using a computer for homework," ranged between 0.60 and 0.69. The reliability of the remaining Three items-"Studying/Doing homework," "Watching TV," and "Doing crafts or others," ranged from 0.50 to 0.59. Results also showed that there was a significant correlation in total sedentary time between self-report measurement and accelerometer-assessed measurement (Spearman's ρ = 0.55), indicating a good criterion-related validity. According to Bland-Altman Plot, compared to accelerometer- assessed measurement, the self-report questionnaire underestimated the total sedentary time per day about 1.36 hours, which was better (i.e., less underestimated) than previous research. Conclusion: The current study showed the preliminary evidence that our questionnaire was useful for measuring the sedentary behavior in Taiwanese adolescents with acceptable reliability and validity.
