The purpose of this study was to adapt Multidimensional State Boredom Scale developed by Fahlman, Mercer-Lynn, Flora and Eastwood (2013) into Turkish language and culture. The scale was applied to a total of 305 students attending Afyon Kocatepe University in Turkey. After Confirmatory Factor Analysis was conducted for testing construct validity, it was determined that the adapted scale consisted of 27 items and five factors (Disengagement, High-Arousal, Low-Arousal, Inattention, Time-Perception). The internal consistency coefficient was found as 0.91 for the whole scale. According to the results obtained through the study, Turkish version of Multidimensional State Boredom Scale is an instrument that can be used in the assessment of boredom proneness.
