Objective To investigate the characteristics of aggressive behavior in methamphetamine addicts and explore its relationship with impulsivity and mental health，so as to provide theoretical basis for management and prevention of aggressive behavior in methamphetamine addicts. Methods A total of 154 male methamphetamine addicts from a drug rehabilitation center in Anhui from July to December 2020 and 65 healthy control groups in the community were selected. Their aggressive behavior, impulsivity, and mental health were measured using a general situation questionnaire, a drug use questionnaire, a Buss Perry aggression questionnaire, a Barratt impulse scale, and a symptom checklist; Divide the median score of aggressive behavior into high aggression group and low aggression group, and compare the impulsive and mental health levels of the high aggression group and low aggression group; Pearson correlation, multiple linear regression and Mesomeric effect test were used to analyze the relationship between the aggressive behavior of methamphetamine addicts and their impulsivity and mental health.. Results The scores of aggression (t=5.365, P<0.01), impulsivity (t=4.036,P<0.01) and mental health level (t=3.011,P<0.01) in the methamphetamine addiction group were hi her than those in the control group. The scores of impulsivity (t=7.254, P<0.01) and mental health level (t=6.597, P<0.01) in the hi h aggression group were hi her than those in the low aggression group (P<0.05). The aggressive behavior of methamphetamine addicts was positively correlated with drug duration (r=0.187, P<0.05), impulsivity (r=0.570, P<0.01), and mental health(r= 0.524, P<0.01) scores (P<0.05). Duration of drug use, impulsivity and mental health level were significant predicative factors of aggressive behavior (F=29.944, P<0.001). The motor impulsivity factor plays a complete mediating role between drug use duration and aggression, with an effect magnitude of 0.025 (t=1.224, P>0.05). Conclusion Methamphetamine addicts who have been taking drugs for a long time, hi h levels of impulsivity, and low levels of mental health are more likely to engage in aggressive behavior.

目的 调查甲基苯丙胺成瘾者攻击行为特征，探讨其与冲动性、心理健康的关系，为甲基苯丙胺成瘾者攻击行为的科学管理与预防提供理论依据。方法 抽取安徽某戒毒所2020年7月至12月的男性甲基苯丙胺成瘾者154名和社区的健康对照组65名，采用一般情况调查表和毒品使用情况调查表、Buss-Perry攻击问卷、Barratt冲动量表、症状自评量表测量其攻击行为、冲动性及心理健康情况；以攻击行为总分的中位数分为高攻击性组与低攻击性组，比较高攻击性组和低攻击性组的冲动性和心理健康水平；采用Pearson相关、多元线性回归、中介效应检验等方法分析甲基苯丙胺成瘾者攻击行为与冲动性、心理健康的关系。结果 甲基苯丙胺成瘾组攻击行为、冲动性、心理健康水平的得分高于健康对照组得分，差异有统计学意义（P<0.05）；甲基苯丙胺成瘾者高攻击性组在冲动性、心理健康水平因子得分高于低攻击性组，差异有统计学意义（P<0.05）。Pearson相关分析结果显示甲基苯丙胺成瘾者的攻击行为与吸毒时间、冲动性、心理健康得分呈正相关（r=0.187、0.570、0.524,P<0.05），多元线性回归分析显示吸毒时间、冲动性、心理健康水平对攻击行为有显著预测作用（B=0.054、0.484、0.118,P<0.05），运动冲动因子在吸毒时间和攻击性之间起完全中介作用，效应量0.025(t=1.224,P>0.05)。结论 吸毒时间长、冲动性水平高、心理健康水平低的甲基苯丙胺成瘾者，发生攻击行为的可能性更大。
