운동참여시간 측정 문항의 타당성 검증 = Validation of the Items Measuring Exercise Participation Time

다국어 초록 (Multilingual Abstract)

The purpose of this study was to verify the validity of self-reported items used to measure exercise participation time and to provide theoretical and empirical evidence for standardizing response categories for self-report multiple-choice items used in various studies. First, an investigation into the current status of major physical activity surveys revealed that most use open-ended time entry items to measure exercise time.
Furthermore, a separate examination of studies using multiple-choice questions revealed that response categories varied across studies. This study collected data from three independent samples and compared three types of self-report items: time-filling, time-selection, and word-selection. After conducting a pre-designed, structured exercise program on Sample I (n=12), we analyzed the similarity between actual exercise time and self-reported responses. Spearman's rank correlation coefficient and simple agreement were very high. However, it appears that self-reported methods, based on human perception and memory, have limitations even when participating in a pre-designed and structured exercise program. Sample II (n=101) was given an open-ended, time-filling items, and seven response categories were constructed based on the responses. Sample III (n=91) was administered a time-selection item composed of the previously established seven response categories. The results showed relatively high correlations among self-report items, but moderate correlations were observed between the word-selection items consisting of adjective phrases and exercise time. Future research should develop standardized response categories for self-reported items using large-scale data.
