Abstract :Objectives: The aim of the study was to investigate the reliability and validity of the Turkish version of the Mental Fatigue Scale insert ignore into journalissuearticles values(MFS); in healthy Turkish population. Methods: This study was held in Hacettepe University, Faculty of Physical Therapy and Rehabilitation between April and August 2019. A total of one hundred thirty-two healthy participants aged between 18-50 years were recruited. Reliability was investigated using test-retest reliability. The internal consistency of MFS was calculated using Cronbach`s alpha coefficient. The validity of the MFS was assessed by comparing the MFS score with the 36-item Short Form Health Survey insert ignore into journalissuearticles values(SF-36); and Checklist Individual Strength Questionnaire insert ignore into journalissuearticles values(CIS-T); scores. Pearson correlation coefficient was used to evaluate validity. Results: The test–retest reliability of the MFS were excellent in healthy Turkish population insert ignore into journalissuearticles values(ICC: 0.91, with a 95% confidence interval of 0.88–0.94);. The scale had high internal consistency insert ignore into journalissuearticles values(Cronbach’s α 0.86);. For the validity, the correlations between the MFS and the total/subscales of CIS-T scores and SF-36 scores were good insert ignore into journalissuearticles values(p<0.001);. The correlations between the MFS and CIS-T subscales insert ignore into journalissuearticles values(subjective feeling of fatigue, r=0.50; concentration, r=0.53; motivation, r=0.42); and CIS-T total insert ignore into journalissuearticles values(r=0.56); were good insert ignore into journalissuearticles values(p<0.001);. Significant correlations were found between the MFS and SF-36 subscales insert ignore into journalissuearticles values(energy/fatigue, r=0.54; emotional well-being, r=0.54, general health, r=0.41); insert ignore into journalissuearticles values(p<0.001);. Conclusion: The Turkish version of the Mental Fatigue Scale has been demonstrated to be valid and reliable to assess mental fatigue in Turkish population. The Turkish Mental Fatigue Scale is suggested to be a valuable tool for assessment of mental fatigue in healthy Turkish population.
