ABSTRACT
UNLABELLED: This study is an explorative research aiming to revise Schedule 5 of Cognitive Behavioural Assessment 2.0 (CBA), that is a reduced version of the Eysenck Personality Questionnaire (EPQ-R). The main goal of this work is to adapt this inventory to the Big Five model by adding new items with good psychometric characteristics, according to the up-to-date Five-Factor personality model. METHODS: These items were chosen on the basis of correlations between the scales of three personality inventories: EPQ-R, Neo Personality Inventory-Revised (NEO PI-R) and International Personality Item Pool (IPIP) test. The questionnaires have been submitted to a sample of 159 subjects, aged 35 to 65. RESULTS: First results confirm good indicators for the dimensions extraversion and Neuroticism, while Psychoticism did not exhibit significant correlations. Moreover, three dimensions in the NEO PI-R and IPIP test (Openness to Experience, Agreeableness, Conscientiousness) showed good psychometric characteristics. CONCLUSIONS: To obtain a new revised form of CBA 2.0 Schedule 5, we suggest the substitution of Psychoticism with three more consistent dimensions belonging to both the NEO PI-R and IPIP test: Openness to experience, agreeableness, conscientiousness. We also propose the new items for these dimensions to be selected from the short form of the NEO PI-R, the NEO Five Factor Inventory (NEO-FFI), as such selection has been already validated.
