  2. [1] With the exception of obesity and TV in the child’s bedroom (which were dichotomous variables), the test statistic is a t-value. For obesity and TV in the child’s bedroom, the test statistic is McNemar’s test statistic (S).
  3. [2] Scale range: 1=low self efficacy to 5=high self efficacy; [3] Scale range: 1=less than once a week to 6 = three or more times a day; [4] Scale range: 0=never, 1=1-3 times a month to 5=every day; [5] Scale range: 1=low support to 5=high support; [6] Scale range: 1=low monitoring to 5=high monitoring; [7] Scale range: 1=never to 5=always.
