Abstract:
Trait neuroticism, time of day, and day of the week were assessed as predictors of state fatigue. After completing an in-lab questionnaire, 176 participants (N = 176) reported their state subjective fatigue three times a day for 8 days. Trait neuroticism was shown to be a predictor of subjective fatigue states in the morning, early evening, at bedtime, and over the course of the 8-day study period. Additionally, results indicated statistically significant differences in subjective fatigue at different points in the day. A statistically significant Neuroticism X Day of the Week interaction indicated that the neuroticism -fatigue relationship was strongest on Tuesday and weakest on Sunday. The relative contribution of personality, time of day, and day of the week variables to state subjective fatigue are discussed.
