Note. The G2 test with 2 df evaluates differences between the waves in both severity and discrimination parameters. Differences between the waves on either parameter are evaluated using 1 df tests. p Values for df 1 tests were adjusted using the Benjamini–Hochberg procedure. Severity parameters that (a) represent a statistically significant difference between waves and (b) exceed our effect size criteria (0.25) are shown in bold.
