Abstract
Background: This research was conducted to objectively evaluate the level of brain fog that may develop due to many reasons.
Subjects and methods: This was a methodological study. This study was conducted in Turkey. Content validity ratio, EFA, CFA,
Kaiser-Meyer-Olkin analysis and Bartlett’s test of sphericity, Item analysis, Cronbach’s alpha coefficient, Spearman-Brown,
Guttman Analysis and test-retest correlations validity-reliability analysis were performed. The statistical meaningfulness level in all
tests was determined as p<0.05.
Results: As a result of context validity, factor analysis and item analysis, a 30 item scale with 3 subscale was obtained. The
variance amount explained by the 3 subscale was on a very good level (77.43%). The fact that all of the Cronbach alpha, Spearman-
Brown and Guttman internal consistency coefficients of the scale and all of its subscale are above 0.70. When the test retest
reliability coefficients of the scale was examined, the scale was found to present consistent results in different applications and the
scale was found to be reliable with regard to the constancy coefficient.
Conclusion: The Brain Fog Scale consists of 30 items and 3 subscales. It is a valid and reliable instrument.
