以躯体化症状为主的抑郁症患者心境一致性记忆研究

A Study of Mood-congruent Memory in Depressed Patients with Somatization Symptoms

目的:探讨以躯体化症状为主的抑郁症患者的心境一致性记忆及与以情绪症状为主的抑郁症患者比较。方法:躯体化症状组、情绪症状组和正常组各30名被试。实验材料96个效价词。实验程序包括学习阶段、干扰实验、再认测验。结果:①躯体化症状组在健康词上,正常组在正性词上有意识提取成绩显著高于其他效价词。②躯体化症状组在健康词上,情绪症状组在负性词上无意识提取平均成绩高于其他效价词。③正常组总体外显记忆成绩显著高于躯体化症状组和情绪症状组。结论:①躯体化症状为主的抑郁症组在外显记忆上表现了对健康词的记忆效应;②躯体化症状为主的抑郁症组在内隐记忆上也可能存在对健康词的记忆效应;③抑郁个体存在外显记忆缺损而不存在内隐记忆缺损。

Objective：To explore the Mood Congruency Memory in depressed patients with somatization symptoms and to compare them with depressed patients with mood symptoms.Methods：Subjects included 30 depressed patients with somatization symptoms,30 depressed patients with mood symptoms and 30 normal persons.Test material consisted of 96 valence words.Procedures were learning phase,interference experiment,and recognition test.Results：①Somatization symptoms group showed significant effect on healthy valence words and other valence words in explicit memory,normal group showed significant effect on positive valence words and other valence words in explicit memory.②Somatization symptoms had more higher average extraction results in healthy valence words in implicit memory,mood symptoms group had more higher average extraction results group in negative valence words in implicit memory.③Compared with somatization symptoms group and mood symptoms group the normal group showed significant effect on total extraction results in explicit memory and on difference in implicit memory.Conclusion：①Somatization symptoms group have a memory bias on healthy valence words in explicit memory and also may have a memory bias in implicit memory;②Disabilities of explicit memory were possibly found in depressed patients.
