Table A.14. Differences between Time 1 and Time 2 EQ-i 2.0 Standard Scores: 2–4-Week Interval

The following table summarizes the differences between time 1 and time 2 scores for the EQ-i 2.0 Total EI score, composite scales, and subscales for the 2–4-week test-retest sample. The first set of results (% of Respondents) lists the percentage of respondents whose scores decreased by more than 15 points, changed by 15 points or less, or increased by more than 15 points over time. Test-retest stability is supported if the majority of respondents show changes of 15 points or less over time, as found in the EQ-i 2.0 2-4 week test-retest sample. The mean and standard deviation of these differences across participants is also provided, along with the 95% confidence interval (CI), which illustrates whether the difference is statistically meaningful for the sample as a whole. That is, if the CI includes zero between the lower bound (LB) and upper bound (UB), the difference is not statistically meaningful, as found for most EQ-i 2.0 scales and subscales.
