aScale: 1 = not at all important, 2 = a little important, 3 = moderately important, 4 = very important, 5 = extremely important
Note: paired t test was used to compare the mean difference between the groups based on a median split for each item, significant at p < 0.002 using the Bonferroni method for multiple comparison adjustment (p = 0.05/24 items), no significant results were found; * represents a non-significant trend at p < 0.05
