a EC-17 items use a five point scale, ranging from 0 to 4, were 0 is never and 4 is always.
b The two EC-17 components derived from principal component analysis had eigenvalues of 9.21 and 1.36.
c EC-17 total score is calculated by adding up the scores and converting to a scale from 0 to 100 where 100 is the best possible score.
