摘要目的 验证画树测验(Koch's Tree-Drawing Test)在医学生人格和心理问题评估中的信度和效度.方法 随机抽取312名年龄在19～ 23岁的医学生施测画树测验;3名评分者对30份测验独立进行画树测验评分;275名被试间隔30 d和39名被试间隔60 d接受重测;部分被试接受16PF、抑郁自评量表和焦虑自评量表测试.结果 不同间隔时间画树测验的重测相关分别为0.570～0.733和0.341 ～ 0.713 (P＜0.05);三名评分者Kendall和谐系数为0.491～ 0.626(P＜0.05);画树测验中相关指标与16PF、SDS、SAS测验相对应指标存在相关性(P＜0.05).结论 画树测验具有较好的信度和效度,能投射出被试的抑郁和焦虑倾向.

abstractsObjective To assess the reliability and validity of the Tree-Drawing Test in medical college students.Methods The study randomly selected 312 aged 19 to 23-year-old medical students to take part in TreeDrawing Test.In addition,a total of 275 college students were selected to receive re-test,30 days late and Pearson correlation coefficient of two tests were calculated.The three raters were invited to assess 30 trees painting score,analyzing the Kendall coefficient of concordance between the scores to verify raters' reliability; parts of students also participated in the 16PF test,SAS,SDS test,analyzing the correlation coefficient between the various test results,in order to assess the effectiveness of the Tree-Drawing Test.Results The re-test reliability in different time was 0.570-0.733 and 0.341-0.713 (P＜0.05),the raters' reliability was 0.491 ～ 0.626(P＜0.05),there are some correlations between Tree-Drawing Test and 16PF,SAS,SDS.Conclusion The Tree-Drawing Test has good reliability and validity; it can be applied to the detection of college students' psychological assessment and psychological problems.
