The hospital anxiety and depression scale   总被引:63,自引:0,他引:63  
A self-assessment scale has been developed and found to be a reliable instrument for detecting states of depression and anxiety in the setting of an hospital medical outpatient clinic. The anxiety and depressive subscales are also valid measures of severity of the emotional disorder. It is suggested that the introduction of the scales into general hospital practice would facilitate the large task of detection and management of emotional disorder in patients under investigation and treatment in medical and surgical departments.  相似文献

A novel test for the selective identification of anxiolytic and anxiogenic drug effects in the rat is described, using an elevated + -maze consisting of two open arms and two enclosed arms. The use of this test for detecting such drug effects was validated behaviourally, physiologically, and pharmacologically. Rats made significantly fewer entries into the open arms than into the closed arms, and spent significantly less time in open arms. Confinement to the open arms was associated with the observation of significantly more anxiety-related behaviours, and of significantly greater plasma corticosterone concentrations, than confinement to the closed arms. Neither novelty nor illumination was a significant contributor to the behaviour of the rats on the + -maze. A significant increase in the percentage of time spent on the open arms and the number of entries into the open arms was observed only within clinically effective anxiolytics (chlordiazepoxide, diazepam and, less effectively, phenobarbitone). Compounds that cause anxiety in man significantly reduced the percentage of entries into, and time spent on, the open arms (yohimbine, pentylenetetrazole, caffeine, amphetamine). Neither antidepressants nor major tranquilisers had a specific effect. Exposure to a holeboard immediately before placement on the + -maze showed that behaviour on the maze was not clearly correlated either with exploratory head-dipping or spontaneous locomotor activity.  相似文献
OBJECTIVE: To review the literature of the validity of the Hospital Anxiety and Depression Scale (HADS). METHOD: A review of the 747 identified papers that used HADS was performed to address the following questions: (I) How are the factor structure, discriminant validity and the internal consistency of HADS? (II) How does HADS perform as a case finder for anxiety disorders and depression? (III) How does HADS agree with other self-rating instruments used to rate anxiety and depression? RESULTS: Most factor analyses demonstrated a two-factor solution in good accordance with the HADS subscales for Anxiety (HADS-A) and Depression (HADS-D), respectively. The correlations between the two subscales varied from.40 to.74 (mean.56). Cronbach's alpha for HADS-A varied from.68 to.93 (mean.83) and for HADS-D from.67 to.90 (mean.82). In most studies an optimal balance between sensitivity and specificity was achieved when caseness was defined by a score of 8 or above on both HADS-A and HADS-D. The sensitivity and specificity for both HADS-A and HADS-D of approximately 0.80 were very similar to the sensitivity and specificity achieved by the General Health Questionnaire (GHQ). Correlations between HADS and other commonly used questionnaires were in the range.49 to.83. CONCLUSIONS: HADS was found to perform well in assessing the symptom severity and caseness of anxiety disorders and depression in both somatic, psychiatric and primary care patients and in the general population.  相似文献
目的评价国产丁螺环酮片治疗广泛性焦虑症的临床效果和副作用。方法采用与安定的随机双盲对照方法,将符合中国精神疾病分类方案与诊断标准第2版修订本广泛性焦虑症标准的206例患者随机分为丁螺环酮组(107例)和安定组(99例),治疗4周。用汉密尔顿焦虑量表、Zung焦虑自评量表、临床总体印象量表及临床疗效和治疗药物副作用量表评定疗效和药物的不良反应。结果丁螺环酮与安定的疗效相近。丁螺环酮对精神性焦虑症状的起效时间较安定稍慢,但没有明显的镇静、嗜睡及体重增加作用,对焦虑症状的治疗具有选择性,尤适用于门诊治疗。丁螺环酮主要的不良反应是轻微的口干及头昏和眩晕等,偶可致窦性心律不齐,但不影响治疗。结论丁螺环酮治疗焦虑症有效,副作用轻微。  相似文献

Anxiety and affective style: role of prefrontal cortex and amygdala.   总被引:31,自引:0,他引:31  
This article reviews the modern literature on two key aspects of the central circuitry of emotion: the prefrontal cortex (PFC) and the amygdala. There are several different functional divisions of the PFC, including the dorsolateral, ventromedial, and orbital sectors. Each of these regions plays some role in affective processing that shares the feature of representing affect in the absence of immediate rewards and punishments as well as in different aspects of emotional regulation. The amygdala appears to be crucial for the learning of new stimulus-threat contingencies and also appears to be important in the expression of cue-specific fear. Individual differences in both tonic activation and phasic reactivity in this circuit play an important role in governing different aspects of anxiety. Emphasis is placed on affective chronometry, or the time course of emotional responding, as a key attribute of individual differences in propensity for anxiety that is regulated by this circuitry.  相似文献

综合医院住院患者焦虑与抑郁症状调查   总被引:25,自引:0,他引:25  
目的:调查综合医院中住院患者焦虑抑郁症状的时点发生比率及在不同科室病种的分布情况。方法:采用综合医院焦虑抑郁量表(HADS),在2003年4月的同一天对综合医院的14个科室中的320例住院患者进行调查。结果:近1/3的患者出现焦虑或抑郁负性情绪;出现焦虑症状阳性者占被调查群体的35.0%,出现抑郁症状阳性者占32.2%,内科患者无论是焦虑和抑郁分,还是出现的焦虑症状和抑郁症状,均显著高于外科患者。焦虑和抑郁症状的发生与患者的年龄密切相关,即随着年龄的增大,其发生率呈增加趋势。结论:综合医院中住院患者的焦虑、抑郁反应是值得重视的现象,应处理这些负性情绪。  相似文献
