Systematic comparative validation of self-report measures of sedentary time against an objective measure of postural sitting (activPAL).

ABSTRACT:

Background

Sedentary behaviour is a public health concern that requires surveillance and epidemiological research. For such large scale studies, self-report tools are a pragmatic measurement solution. A large number of self-report tools are currently in use, but few have been validated against an objective measure of sedentary time and there is no comparative information between tools to guide choice or to enable comparison between studies. The aim of this study was to provide a systematic comparison, generalisable to all tools, of the validity of self-report measures of sedentary time against a gold standard sedentary time objective monitor.

Methods

Cross sectional data from three cohorts (N = 700) were used in this validation study. Eighteen self-report measures of sedenta
