Statistical analysis
SECONDARY
The Shapiro-Wilk test was utilized to assess the distribution of variables, and accordingly, parametric or non-parametric analyses were conducted as appropriate. Summary statistics were utilized to describe the demographic characteristics of the two groups (ABILITY and TAU). Also, independent t-test and Chi-squared analyses were run to ensure that the two groups were comparable at baseline evaluation in terms of age, level of education, neuropsychological profile, and sex distribution. Summary statistics, frequencies, and paired and unpaired comparisons (independent t-test or Mann-Whitney) were reported to test the efficiency of ABILITY versus TAU.To test the effectiveness of the ABILITY treatment on primary and secondary neuropsychological outcome measures (see NCT02746484), we computed delta changes and obtained period effect (PE), treatment effect (TE), follow-up effect (FUE), and carry-over effect (COE). T0 was the baseline evaluation; T1 was the post-treatment evaluation (after 6 weeks), and T2 was the follow-up evaluation (1 year after baseline). PE was calculated on the whole group (ABILITY + TAU group) to measure outcome changes along with time points, both during the treatment period (PE
