NI number of items. [Min, Max] = range or interval between minimum and maximum value: p = potential range, e = empirical or observed range. M = arithmetic mean (95% confidence interval). Mdn median, Mo Mode, α = Cronbach’s alpha based on standardized items. Ordinal α = ordinal coefficient alpha. PA = Pearson-Agostino omnibus test for normality and levels of significance for one-tailed test using a chi-square distribution with two degrees of freedom: non-significant (ns) p > .05 * p ≤ .05, ** p ≤ .01, *** p ≤ .001. Variables: Age = years of age, BDI Beck Depression Inventory-II, BAI Beck Anxiety Inventory, PSS Parental Stress Scale, PWS Psychological Well-being Scale, SDS = Marlowe-Crowne Social Desirability Scale.
