Physical Activity Assessment Research
A key focus in our lab is on improving the validity and utility of measures of physical activity. Accurate measures of physical activity are essential for advancing research in a number of areas including evaluation of health outcomes, public health surveillance, identification of correlates of physical activity and evaluation of behavioral interventions. This work is led by current Ph.D. student Youngwon Kim but many faculty and students affiliated with the lab work with these monitors in their research. Some specific lines of research are summarized below. Click here to access lists of some papers from our team.
A key area of work in our lab is focused on improving the accuracy and utility of physical activity assessments. We have focused the majority of our work on the Sensewear products developed by Bodymedia (now sold by Jawbone). Other commonly used instruments in our research are the Actigraph, the Biotrainer/Actitrac, the MiniMeter, and the ActivPAL Our lab conducts validity and reliability studies as well as methodology papers on appropriate methods for processing and interpreting data from these types of accelerometry - based monitors.

This work has focused on evaluating the validity and utility of the Sensewear monitors for free living physical activity monitoring.

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.

Physical Activity Measurement Survey (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.
