目的：美国一项针对抑郁自杀者的研究和西班牙马德里一项针对所有连续入院的自杀者的研究的结果表明，美国自杀者的攻击性得分更高。这一观察结果使我们对来自两个自杀研究中心的抑郁症患者和对照组进行了比较，并探讨了纽约市（NYC）的患者是否比马德里的患者进行了更大致命性的自杀行为。研究的目的是（1）比较两个城市的自杀者和健康志愿者的攻击性得分;（2）确定较高的攻击性得分是否与自杀企图的较大医疗致死率相关。来自纽约市和马德里的样本分别包括被诊断为严重抑郁症的精神疾病诊断与统计手册第四版的患者（N = 117和N = 133）和健康对照（N = 90和N = 317）。采用方差分析模型，比较了两个研究中心的志愿者和健康志愿者的攻击性得分（采用Brown-Goodwin量表测量）。采用逻辑回归分析评估自杀行为致死率与攻击性得分之间的关系。研究对象为1998 ~ 2001年纽约市和1999年马德里市连续收治的抑郁症自杀者。结果：纽约市抑郁症自杀者比马德里市抑郁症自杀者有更大的自杀企图和更多的终生攻击行为。纽约市健康志愿者也报告了更多的侵略比他们的马德里people.Conclusions：这项试点研究表明，在纽约市自杀行为的杀伤力更大相比，马德里与更高的侵略水平，虽然数据有局限性。需要进行跨文化研究来验证攻击性和高致命性自杀企图是否具有共同的素质，以解释纽约市较高的自杀率。
Objective: Published results from a U.S. study of depressed suicide attempters and a Madrid, Spain, study including all consecutively admitted suicide attempters suggested that aggression scores were higher in U.S. attempters. This observation led us to compare depressed attempters and controls from both suicide research centers and explore whether New York City (NYC) patients carry out suicidal acts of greater lethality than patients in Madrid. The study goals were (1) to compare aggression scores in attempters and healthy volunteers between the 2 cities and (2) to determine whether higher aggression scores are associated with greater medical lethality of suicide attempts.Method: The respective samples from NYC and Madrid included attempters with a DSM-IV diagnosis of major depressive disorder (N = 117 and N = 133) and healthy controls (N = 90 and N = 317). Aggression scores, measured by the Brown-Goodwin Scale, in attempters and healthy volunteers from both sites were compared using an analysis of variance model. The relationship between lethality of suicidal acts and aggression scores in attempters was assessed using logistic regression analyses. NYC subjects were recruited from 1998 to 2001, and Madrid subjects were selected from consecutive admissions in 1999.Results: Depressed suicide attempters from NYC made attempts of greater lethality and reported more lifetime aggressive behavior than depressed attempters in Madrid. NYC healthy volunteers also reported more aggression than their Madrid counterparts.Conclusions: This pilot study suggests that the greater lethality of suicidal behavior in NYC compared to Madrid is related to higher aggression levels, although the data have limitations. Cross-cultural studies are needed to verify whether aggression and higher lethality suicide attempts share a common diathesis explaining the higher suicide rates in NYC.
