*2.5. Statistical Analyses*

Means, standard deviations and percentages are reported for sample descriptions. Since variables were mostly not normally distributed, Mann–Whitney *U* tests for the analyses of single differences of means were used. To analyze potential associations between variables, Spearman rho correlations are reported. All statistical analyses were performed using IBM SPSS Statistics version 24 (IBM Corporation, Armonk, NY, USA). The level of significance for all analyses was set at *α* = 0.05.
