Survival Tree

48
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

    Area of Science:

    • Psychiatry
    • Artificial Intelligence
    • Psychological Assessment

    Background:

    • Depression is a prevalent mood disorder with increasing incidence.
    • Current diagnostic methods rely on subjective patient-psychiatrist conversations, lacking objective biomarkers.
    • The Synthetic House-Tree-Person (S-HTP) test offers a less subjective assessment but is limited by analyst expertise.

    Purpose of the Study:

    • To introduce DeHTP, a deep learning model for automated depression detection using S-HTP drawings.
    • To develop a convenient and objective method for mental health assessment.
    • To overcome the limitations of subjective diagnostic conversations and analyst variability.

    Main Methods:

    • Development of a deep learning model named DeHTP.
    • Application of DeHTP to analyze S-HTP drawings for depression detection.
    • Comparison of DeHTP performance against conventional manual S-HTP analysis.

    Main Results:

    • DeHTP achieved an Area Under the Curve (AUC) of 0.963 and an accuracy of 0.9.
    • The model demonstrated superior performance compared to conventional manual analysis of S-HTP.
    • DeHTP identified 22 drawing features correlated with depression, aligning with existing research.

    Conclusions:

    • DeHTP provides a flexible, convenient, and objective method for depression detection based on S-HTP.
    • The model shows potential for widespread adoption in daily self-mental monitoring.
    • DeHTP serves as a promising auxiliary diagnostic tool for clinical settings.
