Calibration of Self-Report Measures of Physical Activity

An area of emphasis in research by Dr. Welk is on the calibration of self-report measures physical activity. Emphasis in the field has been on refining the accuracy and utility of monitor-based methods for estimating energy expenditure (EE) and time spent in moderate to vigorous physical activity (MVPA) or sedentary behavior (SB). The objectivity of monitor-based measures is a considerable advantage, but report-based tools are more practical and provide valuable information about the context of physical activity behavior. Our lab has been actively working to quantify and address error in a variety of PA assessment tools but specific efforts have been made to improve the accuracy and utility of report-based measures. Read a commentary on the need for calibration of self-report measures in the ACSM Bulletin (Active Voice: Why Self-Report Measures Need Calibration). Summaries of specific calibration projects are summarized below but refer to the separate pages for each project for more details. A listing of related research on improving self-report measures is provided at the bottom.

Physical Activity Measurement Study (PAMS)

This work focuses on evaluating measurement error in self-report measures of physical activity. The team is completing evaluation of data collected as part of a 4 year NIH grant (R01). Click here for details.

Youth Physical Activity Monitoring Study (YPAMS)

This work focuses on developing and calibrating a self-report measure of physical activity to facilitate school based assessments of physical activity. This work was advanced through a Ph.D. project by Pedro Saint-Maurice (now a post-doc on our team). We have developed calibration models and an online application has been developed for continued evaluation and future dissemination.
