BACKGROUND
In this study, we examined whether early-life trauma, psychopathy, and the testosterone/cortisol ratio predicted impulsive aggression problems in veterans.
METHOD
A sample of 49 male veterans with impulsive aggression problems and 51 nonaggressive veterans were included in the study. Logistic regression analysis was performed with early-life trauma, primary and secondary psychopathy, and testosterone/cortisol ratio as continuous predictor variables; impulsive aggression status was entered as a binary outcome measure. Correlation analyses were conducted to examine pairwise relations among the predictors.
RESULTS
Results indicated that early-life trauma and secondary psychopathy, but not the testosterone/cortisol ratio or primary psychopathy, were significant predictors of impulsive aggression status.
CONCLUSIONS
The current results indicate that early-life trauma and secondary psychopathy are risk factors for impulsive aggression problems among veterans. Future studies are needed to determine the exact causal relations among the variables examined here.
背景
在本研究中，我们检验了早年创伤、精神病态以及睾酮/皮质醇比值是否能预测退伍军人的冲动攻击问题。
方法
本研究纳入了49名有冲动攻击问题的男性退伍军人和51名无攻击行为的退伍军人作为样本。以早年创伤、原发性和继发性精神病态以及睾酮/皮质醇比值作为连续预测变量进行逻辑回归分析；将冲动攻击状态作为二元结局指标纳入分析。进行相关性分析以检验各预测变量之间的两两关系。
结果
结果表明，早年创伤和继发性精神病态是冲动攻击状态的显著预测因素，而睾酮/皮质醇比值和原发性精神病态则不是。
结论
目前的结果表明，早年创伤和继发性精神病态是退伍军人冲动攻击问题的危险因素。未来需要开展研究以确定此处所研究变量之间的确切因果关系。
