Psychometric properties of the Spanish version of the self-report Personality Diagnostic Questionnaire-4+ (PDQ-4+) in psychiatric outpatients

We examined the psychometric properties of the Spanish version of the self-report Personality Diagnostic Questionnaire-4+ (PDQ-4+) in a sample of 437 psychiatric outpatients. Psychometric properties were assessed through internal consistency analysis, exploratory factor analysis (EFA) and concurrent validity. Results indicate that the Spanish version of the PDQ-4+ has moderate internal consistency, which was acceptable for 7 of the 12 self-report scales. The factor structure roughly replicated the DSM-IV clusters. The presence of Personality Disorders was associated with the character dimensions of the Temperament and Character Inventory (TCI)Este estudio examina las propiedades psicométricas de la versión española del autoinforme Personality Diagnostic Questionnaire-4+ (PDQ-4+) en una muestra de 437 pacientes psiquiátricos ambulatorios.
