Reliability and validity of time-use surveys in assessing 24-hour movement behaviors in adults.
Article in Journal of exercise science and fitness, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Time-use surveys are considered a valid alternative for assessing physical activity (PA) and sedentary behavior (SB). The International Classification of Activities for Time-Use Statistics (ICATUS) has been widely adopted, as a standardized framework for categorizing time-use data. A classification system has been developed to classify ICATUS-based activities into sleep, SB, light PA (LPA), and moderate-to-vigorous PA (MVPA). This study aimed to evaluate the reliability and validity of ICATUS-based time-use classifications. Methods: Participants aged 18-59 years were recruited from five organizations located in the Bangkok metropolitian area ( Results: Test-retest reliability showed strong absolute agreement in the average time-use estimates for sleep and SB, with ICCs of 0.80 and 0.83, respectively. Moderate agreement was observed for LPA (ICC = 0.71) and MVPA (ICC = 0.51). Moderate validity correlations were found for SB, while LPA showed weak correlations, and MVPA results were inconsistent. Conclusion: ICATUS-based time-use data demonstrated strong reliability and moderate validity for SB, and moderate reliability and low validity for PA in working adults. The classification system appears to be a verified tool, supporting its applicability of time-use data, particularly in developing countries.
