The purpose of this study was to investigate the test-retest reliability and concurrent validity of the Flemish Physical Activity Computerized Questionnaire (FPACQ) in employed/unemployed and retired people. The FPACQ was developed to assess detailed information on several dimensions of physical activity and sedentary behaviour over a usual week. A tri-axial accelerometer, the RT3 Tri-axial Research Tracker, in combination with a written seven-day activity record, was used as the objective criterion measure. In employed/unemployed people, two-week test-retest reliability for several activity variables calculated from the FPACQ was good to excellent with ICCs ranging from .67 to .99. In retired people, lower but, except for time spent eating, still fair to excellent ICCs were found ranging from .57 to .96. Except for the time spent in active leisure time for men and the average energy expenditure related to sports participation in women, correlations between the RT3 and the FPACQ generally supported the relative validity of the FPACQ for employed/unemployed people (r ranging from .37 to .88). In retired people somewhat lower values were found (r ranging from .15 to .85) but most variables still reached at least moderate correlations. Concerning absolute validity, the FPACQ generally overestimated physical activity and underestimated sedentary behaviour compared to the RT3. From this study it can be concluded that the FPACQ is a reliable and reasonably valid questionnaire for the assessment of different dimensions of physical activity and sedentary behaviour.
