Biopsychosocial model: a new perspective in the development of a clinical personality test

Abstract

Mental and personality disorders are linked to different functioning disabilities. Objective was to develop such a clinical personality test, which would merge psychopathology and functioning into one integrative model. Based on the DSM-V criteria and ICF domains: Body functions; Activities & Participation and Environmental factors an initial item pool were developed. A content validity of more than 786 initial items were evaluated by 11 experts and 710 items were selected to the further analysis in the clinical group (N = 400) and non-clinical group (N = 400). After signing an informed consent form participants filled out a set of 5 other measures (M.I.N.I., WHODAS, DASS, demographical questionnaire), which will be used for the analysis of the criterion validity of the new test. Now we are in the middle of the data gathering process. It is expected that based on the same item pool it is possible to develop DSM-V based scales and psychometrically based functional scales linked with the ICF. A combined analysis of psychopathology and functioning is promising and will be useful in many assessment contexts.
