Data on occurrence of suicide from a population of 993 Veterans Administration hospital patients were used to test the validity of the Fliess-Swoboda Biorhythm Theory. Using a novel approach to analysis, semicritical day types were included. Sixty-four day types were generated and divided a priori into five categories which corresponded to predictions of increased or decreased suicides according to biorhythm theory. The results showed that the number of suicides observed was significantly different from the calculated number of expected suicides. The largest discrepancy between expected and observed frequencies occurred in category I for day types with all combinations of critical and semicritical days. It was concluded that biorhythm theory has some validity when the novel methods in this study are employed. The findings have heuristic value and may be useful to clinicians treating male Caucasian Veterans Administration inpatients. Suggestions for future research are also presented.
来自993名退伍军人管理局医院患者群体的自杀发生率数据被用于检验弗利斯 - 斯沃博达生物节律理论的有效性。采用一种新颖的分析方法，纳入了半临界日类型。生成了64种日类型，并根据生物节律理论将其预先分为五类，这五类分别对应自杀率上升或下降的预测情况。结果显示，观察到的自杀人数与计算出的预期自杀人数存在显著差异。对于临界日和半临界日所有组合的日类型，预期频率与观察频率之间的最大差异出现在第一类中。得出的结论是，当采用本研究中的新颖方法时，生物节律理论具有一定的有效性。这些发现具有启发价值，可能对治疗男性白种退伍军人管理局住院患者的临床医生有用。同时也提出了未来研究的建议。
