Outline
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.
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.
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.
The developmental trajectories of early suicidal ideation among adolescents exhibit significant heterogeneity among groups and individual differences.
