Propriedade psicométricas do CD-Quest-S5

Abstract

Introduction: Cognitive distortions are considered one of the main causes of stress and so they have been an area of research all over the world. Cognitive Distortions Questionnaire (CD-Quest) is an instrument that identifies distortions and it is used in Trial-Based Cognitive Therapy. Objective: To analyze psychometric properties of the aforementioned questionnaire, as well as to verify whether cognitive distortions serve as mediators in the impact of stress on well-being. Method: Sample consisted of 1,124 undergraduate students from Federal University of Bahia. After evaluating content validity and data analysis, the instrument was reduced to 5 items (from the initial 15). Content and structure of the items were analyzed by a psychometrist. Finally, in order to investigate the relationship between CD-Quest-S5 and stress-related distortions, the instrument was compared to the original version of the full scale and two subscales that measure frequency of distortions and intensity that is attributed to them. Result: Exploratory factor analysis and concurrent validity indicated that CD-Quest-S5 items present good psychometric properties and generate reliable scores. Conclusion: Study shows that CD-Quest-S5 presents favorable psychometric measures to assess cognitive distortions in a population of university students and stress is directly related to the reduction of well-being in this population.
