了解术后乳腺癌患者的人格特征及心理健康水平，为术后乳腺癌患者的心理干预提供理论依据。

本研究选取2018年5月至2019年1月在江苏大学附属医院甲状腺乳腺外科就医的100例术后乳腺癌女性患者和同期体检的100名健康女性完成树木画投射测验。使用"树木人格测试的指标和神经症状的关系"分析外向、内向、焦虑、抑郁、神经过敏及攻击性6项人格特征以及树冠、茂盛度、树枝、树叶、树干、树基、树根、地面及附属物9项绘画特征。由3名评分者对2组的树木画独立评分。采用两独立样本t检验来比较2组评分的差异。

评分者在外向、内向、焦虑、抑郁、神经过敏、攻击性、总均分的肯德尔和谐系数W分别为0.554、0.653、0.573、0.523、0.671、0.582、0.587(χ²＝48.162、56.771、49.867、45.508、58.359、50.676、51.075，P均<0.050)，评分者信度较高。术后乳腺癌患者在茂盛度、树干2个方面得分均低于健康女性(1.68±0.15比2.52±0.84，t＝6.634，P<0.001；1.72±0.57比2.00±0.99，t＝2.461，P＝0.015)，焦虑、抑郁、神经过敏及攻击性的得分均高于健康女性(5.32±2.83比1.76±0.21，t＝-10.963，P<0.001；2.40±0.13比1.96±0.02，t＝-2.173，P＝0.031；5.60±2.10比2.00±0.41，t＝-14.226，P<0.001；2.22±0.14比1.60±0.33，t＝-4.206，P<0.001)。

术后乳腺癌患者存在神经过敏、攻击性人格、焦虑和抑郁症状，需要临床医师关注。

To understand the personality characteristics and mental health of postoperative breast cancer patients and provide a theoretical basis for psychological intervention.

This study involved 100 postoperative female patients with breast cancer in the Department of Thyroid and Breast Surgery, Affiliated Hospital of Jiangsu University from May 2018 to January 2019 and 100 healthy females for health examination in the same period. They all underwent the tree-drawing test. Based on the relationship between the indicators of the tree-personality test and neurological symptoms, six personality characteristics (extroversion, introversion, anxiety, depression, neurotism and aggression) and nine painting characteristics (crown, lushness, branches, leaves, trunk, base, roots, ground and its appendages) were analyzed. Three professionals independently evaluated tree paintings of two groups. The t test of two independent samples was used to compare the scores between two groups.

The Kendall coefficient W for extroversion, introversion, anxiety, depression, nervousness, aggression and total average scores were 0.554, 0.653, 0.573, 0.523, 0.671, 0.582 and 0.587, respectively, indicating a high inter-rater reliability(χ²=48.162, 56.771, 49.867, 45.508, 58.359, 50.676, 51.075, all P<0.050). Postoperative breast cancer patients showed significantly lower scores compared with healthy women in the lushness and trunk of tree painting (1.68±0.15 vs 2.52±0.84, t=6.634, P<0.001; 1.72±0.57 vs 2.00±0.99, t=2.461, P=0.015). The scores of anxiety, depression, nervousness and aggression in breast cancer patients were significantly higher than those of healthy women (5.32±2.83 vs 1.76±1.59, t=-10.963, P<0.001; 2.40±0.13 vs 1.96±0.02, t=-2.173, P=0.031; 5.60±2.10 vs 2.00±0.41, t=-14.226, P<0.001; 2.22±0.14 vs 1.60±0.33, t=-4.206, P<0.001).

Postoperative breast cancer patients have psychological symptoms including nervousness, aggressive personality, anxiety and depression, which needs special attention from clinicians.
