The computer-based Tree Drawing Test aids in diagnosing depression by analyzing drawing features. It showed significant differences between depressed patients and controls, and between adult and adolescent depression groups.

Area of Science:

  • Psychological assessment
  • Clinical psychology
  • Neuroscience

Background:

  • Depression is a prevalent mental health disorder affecting various age groups.
  • Accurate diagnostic tools are crucial for effective treatment of depressive disorders.
  • The Tree Drawing Test is a projective technique used in psychological assessment.

Purpose of the Study:

  • To evaluate the diagnostic value of a computer-based Tree Drawing Test for depressive disorders.
  • To compare the Tree Drawing Test performance between adolescent and adult depression patients.

Main Methods:

  • A study involving 184 participants (adults with depression, adolescents with depression, healthy controls).
  • Administration of the Tree Drawing Test and standardized depression scales (HDRS, HAMA).

  • Statistical analysis using computer image recognition and calculation techniques.

    • Main Results:

    • Significant differences in drawing parameters (crown area, trunk area, total area) and HDRS scores between adult depression and control groups.
    • Significant differences between adult and adolescent depression groups in trunk area, total area, HDRS, and HAMA scores.
    • Correlation found between drawing features (crown area, trunk area, total area) and HDRS scores.

    Conclusions:

    • The computer-based Tree Drawing Test demonstrates utility as an auxiliary diagnostic tool for depression.
    • Further validation with larger, diverse populations is recommended to confirm generalizability and cultural adaptability.
