Few studies have compared the three suicidality groups—suicidal ideators (SIs), single suicide attempters (SSAs), and multiple suicide attempters (MSAs)—in relation to the suicidal process. This cross-sectional study investigated trends and differences in suicide risk factors across suicidality groups. Using the baseline data of the Korean Cohort for the Model Predicting a Suicide and Suicide-related Behavior, we analyzed trends (Jonckheere-Terpstra or Mantel-Haenszel χ² test) and differences (analysis of covariance or logistic regression) in sociodemographic and clinical factors, psychiatric diagnoses, as well as clinical rating scores on psychopathology (suicidal ideation, depressive symptoms, anxiety symptoms, and problem drinking), trait impulsiveness, and stress across suicidality groups. Across suicidality groups comprising 193 SIs, 207 SSAs, and 376 MSAs, we observed a decreasing trend in age and increasing trends in history of early trauma, familial histories of suicide attempts and suicide, most diagnoses and psychopathologies (suicidal ideation, anxiety symptoms, and problem drinking), trait impulsiveness, and stress—with MSAs more likely to have histories of early trauma and familial suicide, almost uniformly higher proportions of diagnoses, and higher psychopathology rating scores. Overall, increasing trends in suicide risk factors were found across all suicidality groups. Notably, MSAs presented greater proportions of most psychiatric diagnoses and higher degrees of most psychopathologies, motor impulsiveness, and stress, indicating they were at more severe clinical states and were closer to suicide. Mental health professionals should ascertain the number of suicide attempts to identify MSAs, implement more thorough evaluations, and employ additional measures for reducing motor impulsiveness.

很少有研究比较这三个自杀性群体与自杀过程的相关性：自杀意识形态（SI），单自杀企图（SSA）和多自杀企图（MSA）。这项横断面研究调查了自杀倾向人群中自杀危险因素的趋势和差异。使用韩国队列为模型的基准数据来预测自杀和自杀相关行为，我们分析趋势（JONCKHEERE-特普斯特拉或曼特尔-亨塞尔χ ²测试）以及社会人口统计学和临床​​因素，精神病学诊断以及精神病理学的临床评分（自杀意念，抑郁症状，焦虑症状和饮酒问题），特质冲动和压力方面的差异（协方差或逻辑回归分析）自杀集团。在包括193个SI，207个SSA和376个MSA的自杀性群体中，我们观察到年龄下降趋势和早期创伤史，自杀未遂和自杀的家族史，大多数诊断和心理病理（自杀观念，焦虑症状和问题饮酒），特质冲动和压力-MSA更有可能具有早期创伤和家族自杀的病史，几乎一致的较高诊断比例以及较高的精神病理学评分。总体，在所有自杀人群中，自杀危险因素的趋势都在增加。值得注意的是，MSA在大多数精神病学诊断中所占比例较高，在大多数精神病学，运动冲动和压力中所占比例较高，表明他们处于较严重的临床状态，接近自杀。精神卫生专业人员应确定尝试自杀的次数，以识别MSA，进行更全面的评估，并采取其他措施来减少运动冲动。
