Significance of the ANOVA analyses is indicated by the test value of the between clusters versus within clusters mean square (F) and the overall effect size, expressed as fraction of explained variance (η2). Cluster means with different subscripts differ statistically significant from each other (p < 0.01, Bonferroni post-hoc test). Effect sizes for the difference between cluster means (Cohen’s d) were calculated from the difference in means and the pooled standard deviation, derived from the ANOVA analyses
***p < 0.001 in all cases; n. s., not significantly different. The means which have different subscripts differ from each other significantly. The means with the same subscript do not differ significantly. BPN basic psychological needs.
