In order to assess whether or not the missing values were missing at random, we created six dummy variables, one for each of the six cancer worry items.
The PedsQL™ VAS Total Symptom Score is calculated by taking the average of all six items, while the Emotional Distress Summary Score represents the mean of the anxiety, sadness, anger, and worry items, similar to the PedsQL™ Emotional Functioning Scale [ 7].
If the cancer worry item was missing, then the corresponding dummy item was coded a one; if not missing, then a zero.
