Investigated the relationship between childhood onychophagia (fingernail biting) and the suicidal and non-suicidal mean age among 60 hospitalized neurotic veterans. The results show no significant mean age difference between suicidal and non-suicidal veterans; neither does the childhood onychophagia variable "focal suicide" significantly lower either the mean age of suicidal veterans or the mean age of non-suicidal veterans.
研究了60名住院神经症退伍军人童年咬指甲行为与自杀及非自杀平均年龄之间的关系。结果显示，自杀退伍军人与非自杀退伍军人之间的平均年龄无显著差异；童年咬指甲变量“局灶性自杀”也未显著降低自杀退伍军人或非自杀退伍军人的平均年龄。
