Diagnostic agreement between the Personality Diagnostic Questionnaire-4+ (PDQ-4+) and its Clinical Significance Scale

Résumé 0

"Background: The Personality Diagnostic Questionnaire-4+ (PDQ-4+) is composed of a self-report and an interview, the Clinical Signi fi cance Scale, but no studies have reported joint fi ndings. This study is the fi rst to examine the diagnostic agreement between the Spanish version of the PDQ-4+ self- report and its corresponding interview. Method: The sample comprised 235 psychiatric outpatients who were assessed with both instruments. Results: The interview reduced to one half the number of diagnoses provided by self-report (83.4% to 38.3%; mean number of diagnoses 3.29 to .62). Diagnostic agreement was between fair and moderate (mean kappa .45 for PDQ-4+ total score). Conclusions: Findings suggest the utility of jointly administering the PDQ-4+ and its Clinical Signi fi cance Scale to screen for the presence or absence of personality disorders (PDs). Modi fi cations in the diagnostic cut-offs for individual PDs and the PDQ-4+ total score may improve the ef fi cacy of the instrument."
