Reliability and validity of rapid assessment tools for measuring 24-hour movement behaviours in children aged 0–5 years: the Movement Behaviour Questionnaire Baby (MBQ-B) and child (MBQ-C)

Table 7 Associations between MBQ-C reported physical activity and device-measured physical activity

Descriptive Statistics - Median (25^th– 75^th percentile)
		MBQ-C Open (N = 61)		MBQ-C Closed (N = 66)
MBQ-C Active Play (min/day)		240 (180–300)		167 (120–257)
MBQ-C Energetic Play (min/day)		94 (60–163)		64 (39–105)
Mean Acceleration (mg)		42.7 (33.3–48.7)		42.3 (34.2–50.9)
Device Measured Total PA (min/day)		256 (220–295)		258 (225–293)
Device Measured MVPA (min/day)		40 (29–60)		44 (34–51)

N = 107 (N = 72 Group 1 and N = 35 Group 3) parent-dyads were sent an accelerometer (Day 0) and completed the MBQ-C Open on Day 7. Of the 107, N = 17 had missing data for the accelerometer assessment and the MBQ-C; N = 13 had missing or non-valid accelerometer data; N = 16 had missing or non-valid MBQ-C responses
N = 108 (N = 72 Group 2 and N = 36 Group 4) parent-child dyads were sent an accelerometer (Day 0) and completed the MBQ-C Closed on Day 7. Of the 108, N = 11 had missing data for the accelerometer assessment and the MBQ-C; N = 25 had missing or non-valid accelerometer data; N = 16 had missing or non-valid MBQ-C responses
