Clinical Report: Investigation of Tree Drawing Projection Tests for Evaluating Depression Severity
Overview
This study quantitatively analyzes tree drawing projections in patients with depression, those in remission, and normal controls. Significant differences in specific drawing indices were identified, suggesting potential utility in assessing depression severity.
Background
Depression is a prevalent mental health disorder with significant impacts on individuals' functioning and quality of life. Traditional diagnostic methods often rely on structured interviews and validated scales, yet there is growing interest in alternative assessment tools. Tree drawing tests may offer additional insights into the psychological state of patients, warranting further investigation.

Key Findings
Seven quantitative indices showed significant differences among the three groups: depression, remission, and normal controls.
Indices with significant differences included canopy area, height, width, trunk area, width, and total area.
No significant differences were found in trunk height, root dimensions, or ratios involving height and area.
The remission group differed significantly from the depression group but not from the normal control group across the assessed indices.
Tree drawing projections may serve as a supplementary tool for assessing depression severity.
Clinical Implications
The findings suggest that tree drawing tests could be integrated into clinical assessments to help differentiate between varying states of depression. Clinicians may consider these indices as adjunctive measures alongside traditional diagnostic tools.
Conclusion
The study highlights the potential of tree drawing projection tests in evaluating depression severity, indicating a need for further research to validate these findings in broader clinical settings.
