This investigation of adult suicidal behavior and childhood onychophagia among hospitalized psychiatric male veterans suggests that for only personality disorders does childhood non-onychophagia show a significant relationship to adult nonsuicidal behavior. Otherwise, this study indicates that the presence or abscence of childhood onychophagia is not a significant suicidal or nonsuicidal factor among these veterans with a psychotic, neurotic, or personality disorder classification.
这项针对住院精神科男性退伍军人的成人自杀行为与儿童期咬甲癖的调查表明，仅在人格障碍中，儿童期无咬甲癖与成人非自杀行为存在显著关联。否则，这项研究表明，在这些患有精神病性、神经症性或人格障碍的退伍军人中，儿童期咬甲癖的存在与否并非显著的自杀或非自杀因素。
