NCT07670403

Brief Summary

This prospective observational study enrolls 500 skin cancer patients across five Chinese tertiary care centers. The investigators use natural language processing and a hierarchical transformer model to analyse 1.2 million social media posts (Weibo, Douyin, Xiaohongshu, WeChat) for psychological distress and suicide ideation, with prospective validation of an AI Early Warning System.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Suicide Ideation Risk Assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS)

    Proportion of participants with C-SSRS score ≥ 2 (active suicidal ideation with some intent to act, without specific plan) at any follow-up assessment. The C-SSRS is a clinician-administered instrument with a severity subscale ranging from 0 (no suicidal ideation) to 5 (active suicidal ideation with specific plan and intent). Higher scores indicate greater suicide risk.

    24 months

Secondary Outcomes (4)

  • Depression Severity Assessed by the Patient Health Questionnaire-9 (PHQ-9)

    24 months

  • Anxiety Severity Assessed by the Generalized Anxiety Disorder-7 (GAD-7)

    24 months

  • Psychological Distress Assessed by the Hospital Anxiety and Depression Scale (HADS)

    24 months

  • Rate of Psychological Resource Utilization Following AI Early Warning System Alerts
