1) p-value by chi-square test
2) N (%)
1) p-value by chi-square test
2) N (%)
3) Community / Internet
4) Price / Korean-style
1) p-value by chi-square test
2) 5 point scale: 1 = strongly disagree, 2 = disagree, 3 = neutral, 4 = agree, 5 = strongly agree
3) Mean ± SD
1) p-value by chi-square test
2) 5 point scale: 1 = strongly disagree, 2 = disagree, 3 = neutral, 4 = agree, 5 = strongly agree
3) Mean ± SD
1) p-value by chi-square test
2) 5 point scale: 1 = strongly disagree, 2 = disagree, 3 = neutral, 4 = agree, 5 = strongly agree
3) Mean ± SD
4) Reverse coding
1) p-value by chi-square test
2) N (%)
3) 33% of the cells had expected counts of less than 5. Therefore "no change" and "decrease" response categories were combined into a single category for chi-square test.
