A preliminary psychometric study of the Turkish Schema mode inventory-forensic (SMI-F)

Abstract

The Schema Mode Inventory was the first tool that was developed to assess schema modes (SMI; Young et al., 2007). Recently, the SMI was expanded to also assess forensic modes (Bernstein et al., 2014). The main purpose of the current study was to test The Schema Mode Inventory – Forensics’ (SMI-F) reliability and validity. The sample consists of (n = 1271) volunteer undergraduate students across various universities from Turkey. The sample consisted mostly of females (77.5%). The mean age of the whole sample was 20.43 (SD = 2.16, range = 18-57). In order to test the psychometric properties of the SMI-F, we carried out confirmatory factor analysis, multiple regression analysis, correlational analyses for test-retest, and calculated the correlations and internal reliability coefficients. Overall, the results revealed that the SMI-F has satisfactory levels of reliability and validity and might be useful for research and clinical purposes. In conclusion, the inclusion of the forensic modes in this version makes the inventory more comprehensive in reflecting recent developments in the Schema Therapy Model. It could be possible to assess a wide variety of coping modes and formulate a treatment plan for the general population and forensic patients with the SMI-F.
