CYRM-R, PMK-CYRM-R, and The Strengths and Difficulties Questionnaire (SDQ) were completed by participants. Also, internal consistency, face, content, and criterion validity were investigated. A two-factor structure of CYRM-R for Iranian children was identified by CFA: Personal and Caregiver. Results indicated adequate goodness-of-fit and strong internal consistency (Cronbach's alpha = 0.88). Acceptable face, content, and criterion validity of the CYRM-R were reported by positive correlation to the PMK-CYRM-R. No significant relation was found between CYRM-R and SDQ. Findings of the present study support the robust psychometric properties and cultural adaptation of the CYRM-R in Iranian children.

Psychometric properties of Persian version of irritable bowel syndrome- behavioral responses questionnaire (IBS-BRQ).

This study aimed to determine the psychometric properties of Persian version of Irritable Bowel Syndrome-Behavioral Responses Questionnaire (IBS-BRQ). In addition to somatic symptoms and complaints, patients with irritable bowel syndrome have specific dysfunctional behaviors that lead to disease persistence and functional disturbance. Participants included 170 patients with irritable bowel syndrome, who were diagnosed based on ROM-IV criteria and selected from patients referring to the Gastrointestinal Disorders Clinic, as well as 100 persons from the general population in Isfahan in 2020. Both groups completed the 26-item Irritable Bowel Syndrome-Behavioral Responses Questionnaire (IBS-BRQ). Also, questionnaires including the Irritable Bowel Syndrome Symptom Severity Scale (IBS-SSS), Irritable Bowel Syndrome-Quality of Life IBS-QOL, Illness Perception Questionnaire (IPQ-R), Irritable Bowel Syndrome-Patient Satisfaction (IBS-SAT), Hope Scale, Interpersonal Forgiveness Inventory (IFI), and Dysfunctional Attitude Scale- 26-item (DAS-26) were completed to determine the validity of IBS-BRQ. Tests of internal consistency, principal components analyses (PCAs), differentiation analysis, and correlation were used to determine its reliability, along with criterion and construct validity. IBS-BRQ was valid and reliable in both groups with a high degree of internal consistency. Cronbach's alpha was obtained in the sample of patients with IBS and the total sample of participants 0.87 and 0.95 respectively. This scale differentiated significantly between IBS patients and non-patients (p<.001). The criterion validity was high as evidenced by a high correlation with DAS-26 (r=0.53, p<0.001), IBS-QOL (r=0.76, p<0.001), IBS-SSS (r=0.44, p<0.001), IPQ-R (r=0.56, p<0.001), and reverse correlation with IFI (r=-0.031, p<0.001), IBS-SAT (r=-0.23, p<0.001), and HOPE (r=-0.49, p<0.001). The Persian version of the IBS-BRQ proved to be a well-defined behavioral response measure in IBS patients with high validity and reliability, making it a suitable measure to be used in future IBS clinical research in Iran.

This study aims to examine the psychometric properties of the Persian version of the Structured Clinical Interview for DSM-5 for personality disorders (SCID-5-PD) among patients referred to psychiatric centres in Iran. Between March 2017 and June 2019, 287 outpatients and inpatients aged 16 to 75 years who were referred to three psychiatric centres in Tehran, Iran were invited to participate. Patients were interviewed using the Persian version of the SCID-5-PD by two PhD students in clinical psychology who were blinded to patient records. Face validity and content validity of the Persian version of the SCID-5-PD were assessed by five specialists with ≥2 years of clinical experience. The agreement between the diagnoses made with the Persian version of the SCID-5-PD by the two PhD students in clinical psychology and the gold standard diagnoses made with DSM-5 by psychiatrists was determined, as were sensitivity, specificity, and positive and negative likelihood ratios. 109 (43.6%) patients were interviewed again after an interval of 7 to 10 days for inter-rater reliability and test-retest reliability. A total of 250 patients aged 17 to 74 (mean, 32.56) years were included. Face validity and content validity of the Persian version of SCID-5-PD were acceptable. The agreement between the Persian version of SCID-5-PD and DSM-5 (gold standard) was acceptable (kappa >0.4) for the diagnoses of obsessive-compulsive, paranoid, schizotypal, schizoid, histrionic, narcissistic, borderline, and antisocial personality disorders, whereas the agreement was unacceptable (kappa <0.4) for the diagnoses of avoidant and dependent personality disorders. Sensitivity for all diagnoses was high, except for avoidant (0.66) and dependent (0.66) personality disorders. Specificity for all diagnoses was high, except for avoidant personality disorder (0.66). The positive and negative likelihood ratios showed that the SCID-5-PD was accurate for diagnosing all personality disorders, except for schizoid personality disorder. Inter-rater reliability was good for all personality disorders, except for schizotypal personality disorder (0.531). Test-retest reliability was good for all personality disorders. The Persian version of the SCID-5-PD can be used to evaluate those who seek psychotherapy for all personality disorders, except for avoidant, dependent, schizoid, and schizotypal personality disorders.
