The cognitive processes underlying suicidal thinking and behavior are not well understood. The present study examined brooding and reflection, two dimensions of rumination, as predictors of suicidal ideation among a community sample of 1134 adults. Participants completed self-report measures of rumination and depression, and a semi-structured clinical interview that included an assessment of suicidal ideation, at baseline and 1-year follow-up. Brooding was more strongly related to degree of ideation at baseline than was reflection. However, both brooding and reflection predicted whether an individual thought about suicide at 1-year follow-up, even after adjusting for baseline suicidal ideation. Symptoms of depression mediated the relationship between brooding and ideation but not that between reflection and ideation. Implications for the nature of thought processes that result in suicidal thinking are discussed.
导致自杀念头和行为的认知过程尚未得到充分理解。本研究考察了沉思的两个维度——沉思和反思，作为1134名成年人社区样本中自杀意念的预测因素。参与者在基线和1年随访时完成了关于沉思和抑郁的自我报告测量，以及一项包括自杀意念评估的半结构化临床访谈。在基线时，沉思比反思与意念程度的相关性更强。然而，即使在调整了基线自杀意念之后，沉思和反思都能预测个体在1年随访时是否会想到自杀。抑郁症状介导了沉思和意念之间的关系，但没有介导反思和意念之间的关系。本文讨论了导致自杀性思维的思维过程的本质。
