The authors deal with the question of interindividual differences in the circadian periodicity of man and with the possibility of the classification of circadian phase types resulting from this (morning type, evening type, indifference type). For this purpose on 26 test persons on 3 consecutive days at 9 o'clock and at 17 o'clock, respectively, 11 different vegetatively influenced parameters were measured. The quotients from the averaged 9 o'clock and 17 o'clock-values (Q 9/17) formed the basis for the statistical evaluation (cluster analysis in combination with a discriminance analysis). The result of the discrimination was compared with a subjective subdivision of our test group, based on a questionnaire newly developed by the authors, and yielded a portion of error of 4%. Issuing from this, the authors demonstrate an objective investigation method which shall allow to classify any patients simply, quickly and with high reliability into morning, evening and indifference types, respectively.
作者探讨了人类昼夜节律的个体差异问题，以及由此产生的昼夜节律相位类型（早晨型、晚上型、无差异型）分类的可能性。为此，对26名测试对象在连续3天的上午9点和下午5点分别测量了11个受植物神经系统影响的不同参数。上午9点和下午5点平均值的商（Q 9/17）构成了统计评估（聚类分析结合判别分析）的基础。将判别结果与基于作者新开发的问卷对测试组进行的主观细分进行比较，得出的误差率为4%。据此，作者展示了一种客观的调查方法，该方法应能分别将任何患者简单、快速且高度可靠地分类为早晨型、晚上型和无差异型。
