Spss for mac version 15

Pearson's chi-squared test (χ²) was applied to determine the percentage of participants who had changed their clinical classification. The α level (two-sided) was set at 0.05 for all of the analyses. All analyses were computed using SPSS for Mac, version 15 (SPSS Inc., Chicago, USA).

For each scale and test, scores in all the assessments were compared using repeated measures analyses of variance (ANOVA). ANOVA findings that violated the sphericity assumption were accommodated by Greenhouse and Geisser’s conservative degrees of freedom adjustment. Post-hoc simple contrasts (Bonferroni) were conducted for each significant time main effect to determine the source of the significant difference. Data were confirmed to have a normal distribution using the Shapiro–Wilks normality test. The α level was set at 0.05 for all analyses (two-sided). All analyses were computed with SPSS for Mac, version 15 (SPSS Inc., Chicago, USA).
