Abstract
In the analysis of the reliability, the Cronbach α value for the questionnaire was 0.94, indicating very high internal consistency. The test-retest reproducibility analysis was highly significant (r = 0.91, P < .001). In the analysis of the validity, comparing the three study groups, the mean scores of the questions included in each of the dimensions of the test (ANOVA) detected major differences in the dimensions that assess cognitive symptoms, depressive disorders, sleep and psychopathological symptoms. After factor analysis obtained a total of nine axes, allowing a clear distinction between the three study groups.
