Assessment of cognitive flexibility: Reliability and validity studies of Turkish version of the Cognitive Flexibility Inventory

Cognitive Flexibility Inventory (CFI) was developed by Dennis and Wal (2010) in order to measure the cognitive flexibility levels of individuals against the events and circumstances. The purpose of this study is to examine the validity and reliability of Turkish form of CFI 551 university (389 female/162 male) students from Sakarya and Hacettepe Universities participated in the research. The validity of the scale was examined with criterion related validity, exploratory and confirmatory factor analysis methods. The reliability of the scale was examined with Cronbach alpha internal consistency and test-retest methods. The results of factor analysis showed that the scale has a structure of two factors. Cronbach alpha reliability coefficient of CFI was found as .90 for whole of the scale, .90 for “alternatives” sub-dimension and .84 for “control” subdimension. Test-repeat test reliability coefficient of was found as .75 for whole of the scale, .78 for “alternatives” sub-dimension and .73 for “control” sub-dimension. The obtained findings showed that CFI has the sufficient validity and reliability values in measuring the cognitive flexibility levels of Turkish university students
