Appendix A: Standardization, Reliability, and Validity Tables
Table A.13. EQ-i 2.0 Test-retest Correlations and Descriptive Statistics
The following table summarizes the test-retest correlations and time 1 and time 2 means and standard deviations for the EQ-i 2.0 Total EI score, composite scales, and subscales in the 2–4 week and 8-week retest samples. Correlations range from 0.00 to 1.00. Higher values, as found in the EQ-i 2.0 test-retest samples, suggest excellent test-retest reliability.
