Hypothesis
The study aims to compare the validity of the IPAQ and PAQA questionnaires for assessing physical activity in Vietnamese adolescents.
Conclusion
Both questionnaires have a similar and overall poor validity for use as population instruments in Vietnam.
Supporting Evidence
- Reliability of both questionnaires was poor for both the IPAQ and the PAQA.
- Criterion validity of both questionnaires was acceptable but lower in rural areas.
- Both forms poorly estimated time spent on light, moderate, and vigorous physical activity.
Takeaway
The study tested two questionnaires to see how well they measure physical activity in Vietnamese teens, but both were found to be not very reliable.
Methodology
Adolescents completed the IPAQ and PAQA questionnaires, and their responses were compared with data from accelerometers over a week.
Potential Biases
Potential biases due to self-reporting and differences in understanding of the questions between urban and rural adolescents.
Limitations
The reliability and validity of both questionnaires were poor, especially in rural areas.
Participant Demographics
Participants were 16-year-old adolescents from rural and urban areas in Vietnam.
