Özet

Objective: The aim of the study was to investigate psychometric properties of the Repetitive Thinking Questionnaire (RTQ) and the Cognitive Flexibility Inventory (CFI). The RTQ is a trans-diagnostic tool, which aimed to measure repetitive thinking and the CFI is developed for measure the cognitive flexibility. Methods: Research data was collected from 266 undergraduate students of Hacettepe University (187 female, 70.3%; 79 male, 29.7%). Participants completed the informed consent, the RTQ, the CFI, the Cognitive Flexibility Scale, the Positive and Negative Affect Schedule, the Beck Depression Inventory, the Beck Anxiety Inventory. For the test-retest reliability it was reached to 104 people again. Analyses were conducted by using SPSS. Factor analyzes were run and internal validity coefficients were estimated for the RTQ and CFI. Correlations for scales and subscales were evaluated. Results: It was found that the RTQ has a single factor and items which are in the second factor in the original study have to be reversed. The internal validity of RTQ was 0.94 and correlations with the other scales were between 0.12 and 0.35. RTQ-Short Form's internal validity was also 0.94 and correlation with the long form was 0.85. CFI, CFI-alternatives and CFI-control subscales' internal validity were 0.90, 0.89, 0.85 respectively and correlations with the other scales were between -0.13 and 0.48. RTQ and RTQ-Short Form's correlations with the retest were between 0.26 and 0.90. CFI and CFI subscales' correlations with the retest were between 0.22 and 0.81. Conclusion: We have adapted culturally appropriate forms of RTQ and CFI which have good psychometric values to use in future research. Researchers could use the RTQ-Short Form in future research because the short form has very high correlation with the long form and, excellent internal reliability and very similar correlations with the long form to the other criterion variables.
