目的目前,对中国人抑郁体验的现象学理解很大程度上依赖于西方教科书和国际诊断系统中的描述。而临床经验告诉我们,不同地区、不同文化对情绪痛苦的表达有着各自的特点;但中国在这方面还缺乏研究。为此,我们采用民俗学方法对广州地区就诊人群的抑郁体验进行了研究。方法在广州市精神卫生中心门诊,采用定额取样招募40例有抑郁情绪的患者;问及的合适的病人共43人,只有3人不同意参加。采用开放式深入民俗学访谈了解患者的抑郁体验,即让患者用他们自己的话来讲述患病经历。对访谈进行录音,转录为文字并译成英文。对中英文记录分别进行了内容分析。结果除了西方教科书和诊断系统中描述的抑郁症状外,还发现了六个情感体验的类别:本地情感语汇、具身的情绪体验、隐含的忧伤、难以言状的痛苦、情绪不良造成的人际不和谐,以及专注于失眠。结论精神病学教科书和诊断系统中的描述未能涵盖中国抑郁患者对抑郁症状的全部体验。需要进一步研究抑郁体验与生活事件的关联及其在不同文化下的表现方式,这样才能作出与文化相适应的有效诊断。 相似文献

The Hampshire Depression Project: development and piloting of clinical practice guidelines and education about depression in primary health care 总被引:1,自引:0,他引:1
This paper describes the development and piloting of a comprehensive educational programme about recognition and management of depressive illness in primary care. Full evaluation of the effectiveness of the programme is currently underway in a randomized controlled trial, the Hampshire Depression Project (HDP), involving 56 general practices. The programme consists of clinical practice guidelines, practice-based seminars and follow-up sessions. Each part of the programme has been designed to be flexible, clinically oriented and relevant to all members of the multidisciplinary primary care team. The pilot study established the need for a systematic approach to the access of practices and practice teams, and the organization and process of the seminars. Application of this approach was associated with excellent attendance in the main programme. 相似文献

冠心病行为模式与心理状态的相关性探讨 总被引:8,自引:1,他引:7
目的为探讨A型行为在冠心病(CoronaryHeartDisease,CHD)中的作用及与心理状态的相关性。方法对114例CHD及37例非CHD应用心理测验方法对照调查。结果发现A型行为的人易患CHD。CHDA型行为者在焦虑、抑郁、人际关系、认识、敌对性症状因子分较CHD非A型行为者有明显增高。CHD非A型行为者也具有一些特有的心理症状。结论CHD病人的行为模式与病后的某些心理表现呈正相关。 相似文献

Drug-induced improvement of depression may be mediated by changes in sleep physiology. The aim of this study was to relate changes in sleep polygraphic variables to clinical state during treatment with citalopram, a highly specific serotonin uptake inhibitor. Sixteen patients took part. The study was single-blind and uncontrolled. A 1-week wash-out period was followed by 1 week of placebo administration, a medication period of 5 weeks, and a 1-week placebo period. For the entire group a significant decrease of rapid eye movement sleep (REMS) and a significant lengthening of REMS latency were observed initially as well as at the end of treatment. No changes in sleep continuity were found, but non-REMS stage 2 (percentage) was significantly increased. On the basis of clinical change, as expressed by the scores of the Hamilton Rating Scale for Depression, at the end of the citalopram treatment the patient group was split in two halves: eight less and eight more improved patients. The groups did not differ with respect to any sleep polygraphic varible. 相似文献

Life satisfaction in patients with chest pain subsequently diagnosed as coronary heart disease – connection through depressive symptoms? 总被引:3,自引:0,他引:3

The aim of this study was to investigate factors associated with life dissatisfaction in symptomatic patients (n = 144) with chest pain subsequently diagnosed as coronary heart disease (CHD) by coronary angiography. Life dissatisfaction was assessed with a four-item life satisfaction scale (LS), depression with the 21-item Beck Depression Inventory (BDI) and other psychiatric symptoms with the symptom check list (SCL). DSM-III-R Axis I and Axis II psychiatric diagnoses were performed by means of the Structured Clinical Interview. All assessments took place one day before angiography. Twenty-four per cent of CHD patients were dissatisfied with their lives. Life dissatisfaction was associated with being unmarried. Dissatisfied patients had Axis I mental disorders and Axis II personality disorders more frequently than others. Psychiatric and depressive symptoms according to the SCL and BDI, respectively, were also higher among dissatisfied patients. In multiple logistic regression analyses, mental disorders were related to life dissatisfaction when age, sex, employment status, New York Heart Association class, duration of chest pain symptoms and work load were controlled in the model. Married subjects had a lower probability of being dissatisfied with their lives than other subjects (Odds Ratio, OR: 0.23). When BDI scores were included in the model, the only factor independently associated with life dissatisfaction was the severity of depressive symptoms (OR: 1.81). To conclude, life dissatisfaction is not primarily determined by the severity of CHD but by the existence of depressive symptoms. 相似文献

Alexithymia was measured in non-treatment seeking, community-dwelling Holocaust survivors using the Toronto Alexithymia Scale—Twenty Item Version (TAS-20). Scores of survivors with (n = 30) and without (n = 26) posttraumatic stress disorder (PTSD) were compared, and associations among alexithymia, severity of trauma, and severity of PTSD symptoms were determined. Survivors with PTSD had significantly higher scores on the TAS-20 compared to survivors without PTSD. TAS-20 scores were significantly associated with severity of PTSD symptoms, but not with severity of trauma. This study adds to our knowledge of the relationship between alexithymia and trauma by demonstrating that this characteristic is related to the presence of posttraumatic symptoms and not simply exposure to trauma. 相似文献

The presence of depression was evaluated in a cross-section of 50 outpatients with dementia using the self-rated Geriatric Depression Scale and the clinician-rated Cornell Depression Scale. Impaired insight, as manifested by unawareness of dementia, correlated with dementia severity and discriminated a group of patients in whom the self-rated scale failed to show evidence of depression. Discrepancy between the two types of scales occurred among mildly as well as moderately demented patients when insight was impaired. Recognition of this discrepancy suggests that reliance on self-ratings may underestimate the presence and degree of depression among patients with dementia. 相似文献

目的:研究参加社会活动和锻炼对新兴工业化农村社区冠心病患者并发抑郁的影响。方法:对114例在我院就医、属三角镇户籍常住人口的冠心病(CHD)患者进行Zung量表(SDS量表)检测,同时调查其经济状况、健康习惯、参加社会活动和锻炼情况等。用SPSS13.0版统计软件进行统计分析。结果:抑郁发生率37.7%,女性44.3%(27/61)高于男性30.2%(16/53)。70岁以上者47.6%(30/63)高于70岁以下者25.5%(13/51)。缺少社会活动(几乎不参加社会活动)、缺少锻炼(几乎不锻炼身体)都抑郁发生率高,可能是冠心病并发抑郁的独立预测因素。结论:适度参加社会活动和锻炼对CHD患者并发抑郁可能有预防作用。 相似文献
