Table 4 Sedentary behaviour (min/day): Spearman’s rho coefficient correlations for the GPAQ vs accelerometer

From: Validity of the Global Physical Activity Questionnaire (GPAQ) in assessing levels and change in moderate-vigorous physical activity and sedentary behaviour

Sample n Variables Time point Spearman’s rho coefficient (r) Pvalue
