For all frequency items (the first 10 items listed), observational data were dichotomized based on whether the item was observed during ≤50% of observations versus >50%. Survey data were split at the middle of the response scale (none/some of the time vs. most/all of the time). Other items were dichotomized as follows: for PA percent time, ≤25% versus >25% of observed sessions and survey responses of none/just some of the time versus most/all of the time; for PA duration, observed and survey data were recoded as ≤30 minutes versus >30 minutes of the session; and for PA reach, observed and survey data were recoded as none/some versus most/all of the children.
PA data are from Sample 1 only. Snack and beverage data are from Samples 1 and 2.
OST-SBPA, the Out-of-School-Time Snacks, Beverages, and Physical Activity Questionnaire; FV, fruits and vegetables; PA, physical activity.
