房树人测验抑郁评估计分系统信效度研究

An analysis on the reliability and validity of a scoring system of house-tree-person test for depression

目的构建一个适合临床应用的房树人测验抑郁评估计分系统。方法通过文献复习和专家咨询,初步确定评估条目;经预试验,初步确定抑郁评估计分系统;对216例抑郁情绪被试进行测试,验证该系统的信度和效度。结果抑郁评估计分系统由23个抑郁评估条目构成,分为5个因子,累计解释总方差的77.50%。总量表分半信度系数分别为0.87和0.88,内部一致性Alpha系数为0.81,各因子内部一致性Alpha系数为0.75~0.96（P〈0.01）。每个条目Kappa系数为0.71~0.89（P〈0.01）;总量表分校标效度为0.65,各因子校标效度为0.34~0.60（P〈0.01）。总分阳性划界分为4分,与PHI抑郁亚量表阳性判断的一致性检验Kappa值为0.85（P〈0.01）;各因子阳性划界分为1分。结论房树人测验抑郁评估计分系统具有良好的信度和效度,在临床上具有可操作性。

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 216 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.
