bias if the studies that are included with optimal data have specific characteristics. Another approach to harmonization is to use validation studies which report the statistical (e.g., regression) models of relationships between values from the less precise methods and the latent true level of

interpretation methods used in validating the rapidly growing range of step-counting wearable technologies. 7 This need is further highlighted by the fact that only ~5% of consumer step-counting devices have been formally validated. 8 A harmonized methodology for validating these devices would facilitate

GPAQ, 2 studies reported fair/poor correlation and large differences when compared with ActiGraph for measuring SB in adults. 20 , 21 However, this question has not been validated in older adults. High-quality measurement is essential in all elements of SB epidemiology, so that we can learn how SB may

sufficiently sensitive measure to assess school-based PA promotion programs. Published recommendations call for youth to obtain 10,000 to 12,000 steps per day ( 34 ), with a quarter of steps expected to be achieved during the school day ( 13 ). Thus, specific efforts are needed to develop and validate

. To assess whether we would be able to use the data from the women without logs, we conducted a validation study ( Shiroma, Kamada, Smith, Harris, & Lee, 2015 ). Two blinded reviewers visually examined daily accelerometer output and judged whether the device was worn on a particular day (worn versus

estimates of sedentary time ( Crouter et al., 2006 ; Lyden, 2012 ). Likewise, as monitor cut-points are specific to where they are worn, cut-points should be considered location-specific; it is unlikely that a cut-point validated for the hip will lead to accurate classifications at the wrist.

potential influence on children’s health trajectory ( Robinson et al., 2015 ). In order to be able to assess in the future whether there are differences in motor competence perception amongst children from different cultures, it is required to use a validated scale ( Marsh, 1996 ). Thus the primary purpose
