Notes: 1.Statistical significance of differences between psychometrics at intake (0 month) and further assessments (Mixed ANOVA Main Time effect. Tukey test for post hoc comparisons):
p<0.01.
Main Group effects and interaction Time*Group effects for all variables are non-significant.
2. Statistical significance of differences between psychometrics at intake (0 month) and further assessments (Fridman Test and Wilcoxon Signed Ranks Test for post hoc comparisons):
p<0.05.
Mann–Whitney U test Between Group comparisons at all time points are non-significant.
3. The means are the means for all patients with data at a given time point.
