Validation And Calibration Of Self-Report Methods: The Youth Activity Profile, Pedro Frederico De Saint-Maurice Maduro Jan 2013

Validation And Calibration Of Self-Report Methods: The Youth Activity Profile, Pedro Frederico De Saint-Maurice Maduro

Graduate Theses and Dissertations

The development of more accurate and precise methods of assessing physical activity behavior is an important public health research priority. Objective monitoring devices have advantages but the high cost and burden of data processing make them impractical for large scale applications. Subjective (survey-based) tools are inexpensive and easy to use but these suffer from questionable validity. Objective measures are often used to validate less accurate measures such as subjective instruments but this does not directly improve the accuracy or precision of the self-report instrument. The proposed line of research developed and tested a calibration equation approach that enabled data from ...

Validity Of Consumer-Based Physical Activity Monitors And Calibration Of Smartphone For Prediction Of Physical Activity Energy Expenditure, Jung-Min Lee

Graduate Theses and Dissertations

Accelerometry-based activity monitors have become the standard objective method for assessing physical activity (PA) in field-based research [1]. They are small, non-invasive, easy-to use, and provide an objective indicator of physical activity over extended periods of time. The main advantage from a research perspective is they provide an objective indicator of physical activity behavior, thereby avoiding common sources of error in subjective measurement (e.g., self-report). Because of their storage data capacity, it is possible to monitor behavior over extended periods of time and easy to download the information to a computer for processing. Numerous studies have been published on ...
