Abstract

Objectives: This study aims to investigate the psychometric properties of the Persian version of the Self-Report Personality Questionnaire of the Structured Clinical Interview for DSM-5 (SCID-5-SPQ) in Iranian clinical samples. Methods: This is a descriptive survey study. Participants were 289 outpatients and inpatients referred to Iran Psychiatric Hospital, Hazrat-e Rasool General Hospital and the clinic of Tehran Institute of Psychiatry who were selected using a convenience sampling method. In addition to a demographic form and the Persian version of SCID-5-SPQ, the Persian version of SCID-5 Personality Disorder (SCID-5-PD) was used. Finally, face validity, internal consistency (by Cronbach’s alpha), convergent validity (by Spearman correlation test) and the differences between self-reports of women and men (by Mann-Whitney U test) were evaluated. Results: The Persian SCID-5-SPQ showed good face validity. Regarding the convergent validity, all subscales of this questionnaire showed a significant positive correlation with the SCID-5-PD (P<0.001). Moreover, Cronbach’s alpha was reported α=0.93, indicating good internal consistency. Conclusion: The Persian version of SCID-5-SPQ has good validity and reliability, and can be used alone or along with the interviews in psychiatric clinics and hospitals in Iran for screening personality disorders.
