cSF-12: 12-item Short Form Survey.

dScores range from 0 to 100, where 0 implies the lowest level of quality of life, and 100 indicates the highest level of quality of life.

ePCS-12: Physical Component Score.

gGLTEQ: Godin Leisure-Time Exercise Questionnaire.

hSelf-reported physical activity level from the Godin Leisure-Time Exercise Questionnaire. Physical activity score (units) = strenuous (9 METs × times/week) + moderate (5 METs × times/week) + light (3 METs × times/week). One metabolic equivalent (MET) is the amount of oxygen consumed while sitting at rest and is equal to 3.5 mL of oxygen per kg body weight × minutes [26].

iConfidence in using the internet scored on a scale from 0 to 100 (0=not confident at all, 100=extremely confident).
