Percentage agreement between methods for determining the accuracy of energy reporting in 2868 adolescents with an average age of 13.8 y from the Avon Longitudinal Study of Parents and Children¹

	PAPAL			PAMVPA
PAlow	Underreporter (n = 1486, 51.8%)	Plausible reporter (n = 1087, 37.9%)	Overreporter (n = 295, 10.3%)	Underreporter (n = 1065, 37.1%)	Plausible reporter (n = 1217, 42.4%)	Overreporter (n = 586, 20.4%)

Plausible reporter (n = 1170, 40.8%)	12.0	78.8	45.8	2.6	63.5	63.0

¹PA_low, physical activity coefficients assigned as low-active; PA_PAL, physical activity coefficients obtained from estimated physical activity levels; PA_MVPA, physical activity coefficients obtained from minutes of moderate-to-vigorous physical activity. Bowker's Test of Symmetry was significant (P < 0.001), which indicated that there were different proportions of children in the energy-reporting categories between PA_low (based on a low-active PA coefficient), PA_PAL (based on PAL values), and the PA_MVPA (based on accelerometer data). The κ coefficient for interrater reliability was 0.66 (“substantial agreement”) between PA_low and PA_PAL and was 0.53 (“moderate agreement”) between PA_low and PA_MVPA.
