In this study, we examined whether early-life trauma, psychopathy, and the testosterone/cortisol ratio predicted impulsive aggression problems in veterans.
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 indicated that early-life trauma and secondary psychopathy, but not the testosterone/cortisol ratio or primary psychopathy, were significant predictors of impulsive aggression status.
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.
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。
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。
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。
