Abstract：
OBJECTIVE: To analyse the related influencing factors of adolescent major depressive disorder (MDD) with suicidal and self-injurious behaviour (SSIB).
METHODS: A total of 299 adolescents with MDD who were admitted to the psychiatric department of the hospital between February 2022 and July 2023 were selected using the convenience sampling method. The participants were divided into the SSIB group (n = 110) and the non-SSIB group (n = 189) according to whether SSIB was present, and related indicators were collected and compared.
RESULTS: The patients\' ages at the time of their first SSIB ranged from 10 to 18 years old, with a mean age of 13.30 ± 1.74 years. The most commonly injured parts were the lower arm and wrist (42.13%), and the most common injury was cutting, accounting for 40.00% of the total patients. The most common type of self-injury differed by sex (X2 = 17.798, P = 0.006); for men, hitting was the most common, and for women, cutting was the most common. In 51.41% of the patients, the period between the initial thought and the actual committing of the SSIB was less than 5 minutes. The scores of the Eysenck Personality Questionnaire, the Barratt Impulsivity Scale, the Buss-Perry Aggression Questionnaire, the Symptom Checklist-90 (all P < 0.001), and the health-risk behaviour scale (67.47 ± 12.59 vs. 41.58 ± 11.36, t = 9.587, P < 0.001) were significantly increased in the SSIB group compared with the non-SSIB group. In addition, the total score of quality of life (QOL) (11.36 ± 4.32 vs. 16.43 ± 5.64, t = 5.496, P < 0.001) was decreased in the SSIB group compared with the non-SSIB group.
CONCLUSIONS: The SSIB of adolescent patients with MDD is related to various factors, including impulsiveness, aggressiveness, personality traits, QOL, and mental health level.

摘要：
目的：分析青少年重度抑郁障碍(MDD)伴自杀和自伤行为(SSIB)的相关影响因素。
方法：采用便利抽样法，选取2022年2月至2023年7月期间该院精神科收治的299名MDD青少年。根据是否存在SSIB，将参与者分为SSIB组（n=110）和非SSIB组（n=189），并对相关指标进行收集和比较。
结果：患者在第一次SSIB时的年龄范围为10至18岁，平均年龄13.30±1.74岁。最常见的受伤部位是下臂和手腕(42.13%),最常见的伤害是割伤，占患者总数的40.00%。最常见的自我伤害类型因性别而异（X2=17.798，P=0.006）；对于男性，打人是最常见的,对于女性来说,切割是最常见的。在51.41%的患者中，从最初的想法到实际的SSIB提交之间的时间少于5分钟.艾森克人格问卷的得分，Barratt冲动量表,巴斯-佩里侵略问卷，症状检查表-90（所有P<0.001），和健康风险行为量表(67.47±12.59vs.与非SSIB组相比，SSIB组41.58±11.36，t=9.587，P<0.001）显着增加。此外,生活质量总分(11.36±4.32vs.与非SSIB组相比，SSIB组降低了16.43±5.64，t=5.496，P<0.001）。
结论：青少年MDD患者的SSIB与多种因素有关，包括冲动,侵略性,人格特质，QOL,心理健康水平。
