The aim of this study was to understand the longitudinal trajectory of suicidal ideation (SI) among Chinese medical students and the role of childhood trauma (CT).
Using a whole-group sampling method, we assessed SI in 2192 (male = 834, female = 1358) medical students on three occasions over a period of one year. The Suicidal Ideation Self-Assessment Scale (SISAS) and the Childhood Trauma Questionnaire-Short Form (CTQ-SF) were used to assess SI and CT. The growth mixture modeling (GMM) was used to classify the developmental trajectory of SI.
A greater number of medical students were experiencing suicidal ideation during the COVID-19 pandemic. The trajectory of SI among medical students was divided into two groups: a low risk, slowly rising group and a high risk, continuous group. The low risk, slowly rising group had a significant time effect (B = 1.57, p < 0.001) and showed a slowly increasing trend. Emotional neglect (EN), physical neglect (PN), emotional abuse (EA) and physical abuse (PA) all had significant positive predictive effects for the high risk, continuous group (B = 0.18-0.65, P < 0.01).
The trajectory of SI among medical students can be divided into a low risk, slowly rising group and a high risk, continuous group; the more EN, PN, EA and PA experienced during childhood, the more likely medical students are to develop a high risk, continuous state of SI.
本研究旨在了解中国医学生自杀意念（SI）的纵向轨迹，以及童年创伤（CT）的作用。
采用整群抽样法，在一年的时间内，对 2192 名医学生（男=834，女=1358）进行了三次 SI 评估。采用自杀意念自评量表（SISAS）和童年创伤问卷-短式量表（CTQ-SF）评估 SI 和 CT。采用增长混合模型（GMM）对 SI 的发展轨迹进行分类。
在 COVID-19 大流行期间，有更多的医学生出现自杀意念。医学生 SI 的轨迹分为两组：低风险、缓慢上升组和高风险、持续组。低风险、缓慢上升组具有显著的时间效应（B=1.57，p<0.001），呈现缓慢上升趋势。情感忽视（EN）、躯体忽视（PN）、情感虐待（EA）和躯体虐待（PA）对高风险、持续组均有显著的正向预测作用（B=0.18-0.65，P<0.01）。
医学生 SI 的轨迹可分为低风险、缓慢上升组和高风险、持续组；儿童时期经历的 EN、PN、EA 和 PA 越多，医学生发展为高风险、持续 SI 状态的可能性就越大。
