Sample size: N = 330. Internal consistency: NI = number of items, Ordinal α = ordinal coefficient alpha, and α = Cronbach’s alpha based on standardized items. Convergent validity: AVE average variance extracted, ω = McDonald’s omega coefficient. Summary statistics: [Min, Max] = observed range or interval between minimum and maximum value (potential range from 1 to 4), M = arithmetic mean (95% confidence interval using t-distribution), Mo mode, SD standard deviation, G1 = Fisher-Pearson skewness coefficient for sample (95% confidence interval using z-distribution; standard error: G1SE = 0.134), G2 = Fisher-Pearson excess kurtosis coefficient for sample (95% confidence interval using z-distribution; standard error: G2SE = 0.268), Pn = nth percentile. Normality: PA = Pearson-Agostino omnibus test for a null hypothesis that the data are normally distributed: PA = (G1/G1SE)2 + (G2/G2SE)2; levels of significance for one-tailed test: non-significant (ns) p > .05 * p ≤ .05, ** p ≤ .01, *** p ≤ .001.
