* Note: Reliability estimates obtained from a quality-filtered quota sample in Germany (ntest = 420, nretest = 202; based on a German adaption of the scales; presented before the ‘/’) and a quality-filtered parallel sample in the U.K. (ntest = 440, nretest = 199; presented behind the ‘/’) in a 3-form planned missingness design; rtt: test-retest reliability with an interval between 2-3 weeks using pairwise complete observations; Ω: McDonald’s Omega composite reliability based on the fitting scalar invariant (i.e., across Germany and the U.K.) multi-group CFA measurement model including three correlated latent core strength variables and an uncorrelated latent acquiescence variable using full information maximum likelihood (FIML).
