A brief inventory for DSM-5 personality disorders: The development of Coolidge Axis II Inventory Plus Turkish-Short Form

Objective: The purpose of this study is to develop a short-form of Coolidge Axis II Inventory Plus Turkish Form (CATI+TR) specific for Turkey, which assesses personality disorders in the DSM-5, and to examine the psychomet-ric properties of this form (CATI+TR-SF). Methods: Two samples were used in the study that to be (49.8% male, 50.2% female and mean age 34.89±11.08) community sample of 648 individuals and (35.5% male, 64.5% female and mean age 31.01±10.03) clinical sample of 138 individuals. Forty-three of the participants formed the test-retest reliability sample. In the context of convergent and discriminant validity, it were applied together CATI+TR-SF to community and clinical sample of 106 persons The Structured Clinical Interview for DSM-III Axis II Disorders-Per-sonality Ouestionnaire (SCID-II-PQ) and to community and clinical sample of 107 persons Personality Belief Ques-tionnaire-Turkish Short Form (PBQ-TSF). Results: In the reliability study, the Cronbachs alpha for (CATI+TR-SF) was between 0.66 and 0.77 for subscales. Correlation coefficient values for test-retest reliability were between 0.77 and 0.89. With respect to Personality Disorders scales of CATI+TR-SF, an exploratory factor analysis with principal components analysis method and varimax rotation revealed a two-factor structure with eigenvalues greater than 1, explaining 64.66% of the total variance, corresponding to the two major clusters of PDs. In the convergent validity analyzes, the correlation coefficients of CATI+TR-SF subscales with PBQ-TSF subscales ranged between 0.35 and 0.64, SCID-II-PQ subscales between 0.27 and 0.78. In the discriminant validity analysis, CATI+TR-SF personality disorder scores were found to be significantly higher in favor of the clinical sample, and CATI+TR-SF was found to differentiate clinical and community samples to SCID-II-PQ (except schizoid PD). Discussion: Findings obtained because of the analyzes showed that CATI+TR-SF is a valid and reliable scale. [Anadolu Psikiyatri Derg 2018; 19(0.200): 14-21]
