Scores of somatization, sensitivity of interpersonal relation, depression, anxiety, hostility, fear, monomania, psychiatric and total scores, total average scores, positive numbers, and positive average numbers of the experimental group were higher than those of the control group（P＜0.01）. Correlation analysis showed that age was positively correlated with the mood of depression and negative copying（P＜0.05）, educational level was negatively correlated with the mood of depression and anxiety, and serum albumin was negatively correlated with negative copying（P＜0.05）. Conclusion: The mood of depression and anxiety is an obvious symptom in nondialysis patients with chronic kidney disease.

结果：慢性肾脏疾病组焦虑情绪、抑郁情绪和消极应对显著高于对照组（P＜0.01）；人格类型稳定性两组相比差异有统计学意义（P＜0.01）；两组心理健康状况相比，躯体化、人际关系敏感、抑郁、焦虑、敌对、恐惧、偏执、精神病性及总分、总均分、阳性数、阳性均数差异均有统计学意义（P＜0.01）；心理指标与被试变量的相关性分析显示年龄与抑郁、消极应对呈正相关（P＜0.05）；受教育程度与焦虑、抑郁呈负相关（P＜0.05）；血清白蛋白与消极应对呈负相关（P＜0.05）；而性别、职业、肾功能、血红蛋白与焦虑抑郁情绪、应对方式及心理健康状况总分、总均分、阳性数无相关性。
