Psychometric properties of the Polish version of the Cognitive Triad Inventory (CTI). A preliminary study.

Abstract

Aim of the studyThe aim of this study was to translate and evaluate the Polish version of the Cognitive Triad Inventory (CTI), an instrument developed to measure the cognitive triad conceptualized by Beck as an important variable in depression.Subject or material and methodsA sample of N=86 adults included depressed, non-depressed and prisoners completed a survey test battery comprised of CTI, CES-D, and STAI.ResultsThis study provided evidence for the reliability and validity of the Polish CTI. Exploratory factor analysis showed the one-factor model to best fit the data, as in the American version.DiscussionThe division into self, world, and future is an unwieldy taxonomy with highly overlapping categories. Because the three-factor model did not fit the data very well it is suggested that it would be reasonable to label that one CTI factor “Self-Relevant Negative Attitude.”ConclusionsThis study examined the psychometric properties and factor structure of the CTI on both clinical and nonclinical samples, and confirms that CTI may be used to measure the cognitive triad. Evaluation of suicidal ideation was also discussed.
