title: [Subjective wellbeing of shift workers in relation to individual characteristics of circadian rhythm].
abstract: With a goal to test the influence of individual traits of circadian rhythms on the tolerance of shiftwork a circadian questionnaire has been developed with the method of factors analysis. There are two scales in the final form of the questionnaire representing two chronobiological characteristics: morningness - eveningsness (circadian phase-position) and flexibility of the sleep-wake-rhythm. Sex- and age-norms exist for the two scales. Reliability and validity have been demonstrated. The results of an epidemiological study shows that the hypothesis of better adjustment to shiftwork of evening-types can not be verified. A better predictor of tolerance to shift work in terms of wellbeing seems to be the individual circadian trait flexibility of sleep-wake-rhythm.
