WebInternal consistency for the Y-BOCS-II-SR-T was calculated with Cronbach’s alpha coefficient (α), and the factor analyses were completed. Pearson’s correlation was used in determining convergent and divergent validity among the other measures. Results: The mean score of the Y-BOCS-II-SR-T total score was 20.71±11.16. WebIn the proposed study, the alpha coefficient obtained is 0.869, which indicates a good ability of the items of the questionnaire to evaluate the same latent factor in subjects, neuroticism in our case.
