Validation Studies of the Stanford Brief Activity Survey (SBAS) of on-the-job activity and leisure-time activity
Taylor-Piliae et al. 2006
- Two investigators established the face and content validity of the SBAS by independently grading each response category in the inactive, light, moderate (3.0–4.9 METs), hard (5.0–6.9 METs), and very hard (≥7.0 METs) activity categories, using established metabolic equivalents. Receiver operating curves were calculated to determine if SBAS could detect recommended physical activity levels of 150 or more minutes/week at moderate or greater intensity, derived from PAR minutes/week.
- 1,010 participants (38% women), aged 65.8 (±2.8) years
- Summary Results
- SBAS classification at moderate or greater intensity had a sensitivity of 0.73 and a specificity of 0.61 to detect the national physical activity recommendations of 150 or more minutes/week at moderate or greater intensity, using PAR minutes/week at moderate- or higher-intensity activity (Figure 2 in paper).
