摘　　要：目的 考察青少年早期自杀意念的动态发展轨迹,以及性别、留守状态、是否独生、走读情况和社会支持等对自杀意念发展轨迹的影响。方法 采取整群抽样法,于2023年3~12月选取湖南省某城区中学989名在校7年级学生进行3次追踪调查,使用青少年自杀意念量表(PANSI)与青少年社会支持量表(CASSS)进行问卷调查,采用LGMM模型分析探究青少年早期自杀意念的不同类别。结果 青少年早期自杀意念的发展轨迹存在4个潜在类别,分别是C1组定义为“高风险—稳定型”(7.2%)、C2组定义为“中风险—恶化型”(8.8%)、C3组定义为“中风险—稳定型”(11.1%)以及C4组定义为“低风险—稳定型”(72.9%)。女生、留守、独生是青少年早期自杀意念发展轨迹的危险因素(均P<0.05),社会支持是发展轨迹的保护因素。结论 青少年早期自杀意念的发展轨迹具有显著的群体异质性与个体差异性。Objective To investigate the dynamic developmental trajectories of early suicidal ideation among adolescents,and the influence of factors such as gender,left-behind status,only-child status,boarding status,and social support on the trajectories of suicidal ideation development.Methods A cluster sampling method was employed to conduct three follow-up surveys among 989 7th-grade students in a certain urban middle school in Hunan Province from March to December 2023.The adolescent suicidal ideation scale(PANSI) and adolescent social support scale(CASSS) were used for questionnaire surveys.A latent growth mixture model(LGMM) was utilized to analyze and explore different categories of early suicidal ideation among adolescents.Results Four potential categories of developmental trajectories of early suicidal ideation among adolescents were identified,labeled as C1 group "high-risk-stable"(7.2%),C2 group "medium-risk-worsening"(8.8%),C3 group "medium-risk-stable"(11.1%) and C4 group "low-risk-stable"(72.9%).Being female,left-behind,and only-child were identified as risk factors for the developmental trajectories of early suicidal ideation(all P<0.05),while social support was identified as a protective factor for these trajectories.Conclusion The developmental trajectories of early suicidal ideation among adolescents exhibit significant heterogeneity among groups and individual differences.
