Adaptation of the Cognitive Triad Inventory into Turkish: a Validity and Reliability Study.

INTRODUCTION

The aim of this study was to assess psychometric properties of the Turkish version of The Cognitive Triad Inventory developed to use cognitive triad based on Beck's depression model.

METHODS

The study sample included 337 (female 72.2%, male 27.8%) students from Hacettepe University. Reliability was evaluated by test-retest analysis and internal consistency coefficients. For validity, explanatory and confirmatory factor analyses were performed. In addition, the scales which are assumed to measure similar cognitive structures were used to examine convergent validity. The Cognitive Triad Inventory, Beck Depression Inventory and The Hopelessness Scale were administered to the participants.

RESULTS

The Cronbach Alpha coefficient reliability of The Cognitive Triad Inventory (r=0.91) showed that internal consistency reliability of inventory is high. It was found that test-retest reliability coefficients range from 0.74 to 0.94 and are high for an interval of 4 weeks (p<0.005). Confirmatory factor analysis has supported three factor structure of the inventory: "view of self", "view of world" and "view of future". The analysis showed that the model has high goodness of fit. Comparison with three self-report measures released that Cognitive Triad Inventory and its subscales have good convergent validity.

CONCLUSION

The Turkish version of the Cognitive Triad Inventory has been found to be a valid and reliable measure that can be used for the university students of Turkey.
