To extract and quantitatively analyze tree drawing projection indices in patients with depression, patients in remission, and a normal control group, to explore characteristic indicators of tree drawing projections in individuals with depression.
Key Findings:
Significant statistical differences were found in canopy area, canopy height, canopy width, trunk area, trunk width, total area, and the ratio of canopy width to trunk width among the three groups (p values: < 0.001, < 0.001, < 0.001, 0.003, < 0.001, 0.004, < …
No significant differences were found in trunk height, root width, root height, root area, total height, the ratio of canopy height to trunk height, and the ratio of canopy area to trunk area.
The remission group showed significant differences compared to the depression group in several indices, but no significant differences were found between the remission group and the normal control group.
Interpretation:
The quantitative indices of tree drawing projections can differentiate between the depression group, the remission group, and the healthy control group.
Limitations:
Conclusion:
Seven quantitative indices showed significant differences among the groups, while seven indices showed no significant differences.
