Physical+Activity+Spatial+Analysis

=Physical Activity Spatial Analysis=

During PALMS Pilot I, subjects were administered a Physical Activity Spatial Analysis (PASA) interview at each measurement visit. The PASA is a semi-structured interview to identify/confirm device wear times, transportation mode, and behavior related to heart rate (e.g. stress, caffeine consumption) and activity. Participants were shown a map (Google Maps) containing all available data streams (i.e., heart rate, acceleration intensity) for each day. Participants were asked to recall their daily acitivities, starting with the most recent and working backwards in an attempt to identify and/or confirm the data (i.e., type of actiivty, device drop out, non-compliance). When appropriate, the 'street-view' function on Google Earth was used to help the participant recall bouts of activity (or inactivity). For each day, the activity description (i.e., walking to work), the trip number (per day), and comments were recorded on the PASA worksheet.

These self-reported data were combined with the data collected by the devices in order to provide additional details on the contextual factors related to PAEE.

For PALMS Pilot II, the PASA was revised and renamed: Physical Activity Spatial-Temporal Analysis (PASTA).
