Abstract:
Objective To develop a quantitative scoring system for the House -Tree -Person (H -T -P)test.Methods By literature review and expert consultation,preliminary evaluation items were defined.After pilot test,the scoring system for assessing depression were defined.A total of 21 6 cases of patients with depressive mood disorder from the Tong De hosptial of the Zhejiang Province were tested.The reliability and validity of a scoring system of house -tree -person test for depression were analyzed.Results The scoring system of depression evaluation including 23 items and 5 factors,could explain 77.50% of the cumulative total variance.The split -half reliability of the system was 0.87 and 0.88,and the internal consistency reliability of the system was 0.81 .The Kappa coefficient of each item was 0.71 -0.89 (P <0.01 ). The standard validity of the scale was 0.65,and the criterion validity of each factor was 0.34 -0.60 (P <0.01 ).The critical point of positive demarcation was 4,and the critical point of positive demarcation of each factor was 1 .The Kappa value of the consistency test was 0.85 with the PHI Depression Inventory.Conclusion This study demonstrates H -T -P scoring system has acceptable validity and internal consistency.
