Abstract
A Validity and Reliability Study of the Turkish Version of the Counterfactual Thinking Scale for Negative Events Scale
The purpose of present study is to adapt the Counterfactual Thinking Scale for Negative
Events (CTNES) and to study its validity and reliability. Present study was conducted on
241 participants, 109 female and 132 male. Cronbach’s alpha, McDonald’s omega, splithalf
test reliability and corrected item-total correlations were used for the findings on the
reliability of the scale. Confirmatory factor analysis was applied to evaluate the construct
validity of the scale. Confirmatory factor analysis results showed that the goodness of fit
values (CMIN = 167.758, SD = 98, CMIN/SD = 1.71, RMSEA = .054, GFI = .92, CFI
= .93, IFI = .93, TLI = .91, SRMR = .054) were at an acceptable level. Analysis results
showed that the factor structure of the Turkish form of the scale provides good fit values
and that the four-factor factor structure of the scale is confirmed in parallel with the
original scale. When analyzed in terms of reliability values of the Turkish form of the
scale, it was found that the Cronbach’s alpha value was .87, the McDonald’s omega value
was .87, the split-half test reliability was .80, and the corrected item total correlations
were ranked between .40 and .58. Analysis results showed that the Turkish version of the
Counterfactual Thinking Scale for Negative Events (CTNES) can be considered as a valid
and reliable measurement tool.
