Notes * p < .05, ** p < .01; high mean values demonstrate a higher symptom severity; Explanation of abbreviations: M = mean; SD = standard deviation; N = number of participants; dfM = degrees of freedom for the effect of the model; dfR = degrees of freedom for the residuals of the model; effect sizes were analysed according to ANOVA with repeated measurements; ω2 = omega squared effect size; Interpretation of the effect size ω2: .01 ≤ ω2 < .06 – small effect; .06 ≤ ω2 < .15 – moderate effect; ω2 ≥ .15 – large effect.
