Computer-based tree drawing test in adolescents and adults with depression

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.
