Abstract

Objective To explore the influencing factors of suicidal ideation in first-episode adolescent patients with depression in an ethnic minority concentrated area in southern Yunnan. Methods A total of 277 first-episode adolescent patients who presented to the psychiatric outpatient departments of Yuxi City People’ s Hospital and Mojiang County People’ s Hospital between March 2023 and July 2024 with chief complaints of depressed mood and met diagnostic criteria for depression were enrolled. Patients were divided into two groups: those with suicidal ideation （n = 128） and those without suicidal ideation （n = 149）. Psychological factors were evaluated using the Symptom Checklist-90 （SCL-90）, Beck Anxiety Inventory （BAI）, Beck Depression Inventory （BDI）, Pittsburgh Sleep Quality Index （PSQI）, and Adolescent Self-Rating Life Events Checklist （ASLEC）. Logistic regression analysis was applied to determine independent predictive factors of suicidal ideation in first-episode adolescent depression patients （total sample and female subgroup）. A combined predictive probability model was constructed based on Logistic regression coefficients, and the predictive efficacy of individual factors and the combined model for suicidal ideation was assessed by plotting Receiver Operating Characteristic （ROC） curves. Results The ASLEC total score, SCL-90 total score and subscale scores, BAI total score, BDI total score, and PSQI total score in the group with suicidal ideation were significantly higher than those in the group without suicidal ideation （P < 0.01）. Multivariate logistic regression analysis showed that age, academic pressure subscale score, depression subscale score, hostility subscale score, and anxiety subscale score were independent predictive factors of suicidal ideation in first-episode adolescent depression patients. For female first-episode adolescent depression patients, age and SCL-90 mean total score were independent predictive factors of suicidal ideation. ROC curve analysis indicated that age, academic pressure subscale score, depression subscale score, hostility subscale score, anxiety subscale score, and their combination all had significant predictive value for suicidal ideation in first-episode adolescent depression patients （P < 0.05）, with the combined model showing the highest predictive efficacy （AUC = 0.942）. In female first-episode adolescent depression patients, age, SCL-90 mean total score, and their combination also had high predictive value for suicidal ideation （P < 0.05）, with the combined predictive model similarly demonstrating the highest efficacyas well （AUC = 0.758）. Conclusion The independent predictors of suicidal ideation in first-episode adolescent depression patients are younger age, academic stress, depression, hostility and anxiety factor scores. The combined predictive efficacy is significantly better than that of a single factor. Younger age and the total symptom severity of SCL -90 are the specific independent predictors for female patients.
