  1. 1. PA = Physical activity; TV = television
  2. 2. Low kappa defined as poor or slight agreement according to cut-offs by Landis & Koch [35].
  3. 3. For the criterion validity study, questions on whether parents restricted their child's computer use or computer game use were combined.
  4. *Kappa could not be calculated due to the limited variation in response.
