Article Abstract:
A study reports the school-level interclass correlation (ICC) for moderate to vigorous physical activity (MVPA) from the Trial for Activity in Adolescent Girls (TAAG) baseline survey of sixth grade girls and describes the relationship between the schedule of data collection and the ICC. The school-level ICC is higher when estimated from a single wave compared with three waves and across weekdays compared with weekend days.

Article Abstract:

The study suggested that collecting information on two leisure activities appeared to be the most efficient balance for accuracy of recommended activity and also for specific types of leisure activities.
