To assess the mental health of patients admitted to hospital with suspected ischaemic heart disease, by means of two instruments, the General Health Questionnaire (GHQ-28) and the MH (1-5) dimension of the SF-36 Health Survey Questionnaire, and to compare the psychometric properties of both questionnaires in this population.
A study was conducted of 185 patients consecutively admitted to hospital with suspected ischaemic heart disease, classified into four groups: Acute Myocardial Infarctus (AMI), unstable angina, non-ischaemic cardiologies, and non-cardiological conditions. Their mental health was assessed by means of the GHQ-28 and the MH 1-5 sub-scales of the SF-36; the validity of the results were analysed by the association of each instrument with socio-demographic (age, sex, social class, and educational level) and clinical (co-morbidity, risk factors, diagnostic groups and background to the illness) variables. The correlation of each instrument with other sub-scales of the SF-36 was studied. The internal consistency was measured by Cronbach's alpha, together with the item-internal consistency and item-discriminant validity.
Of the population studied, 71.9% were males and the mean age was 60.2 years (SD: 10.4). The diagnosis for 33.5% was AMI and for 37.8% unstable angina. For all the variables studied, the scores in the two instruments were ordered in the same way, and were significantly worse for females and for the most disadvantaged social class. None of the scales discriminated in respect of the diagnostic group or the presence of comorbidity. However, a linear relationship was observed with risk factors. Cronbach's alpha was 0.95 for the GHQ-28 and 0.80 for the MH 1-5. Correlations with the other dimensions showed ranges of -0.35 to -0.61 for the GHQ-28 and of 0.26 to 0.61 for the MH 1-5. These were highest for the Vitality and Social Functioning sub-scales in both instruments.
The subjective perception of mental health is measured in a similar way by both the MH 1-5 scale of the SF-36 and the GHQ-28. However, since the MH 1-5 questionnaire is shorter, it should be administratively easier to introduce into routine cardiological practice.
通过使用两种工具，即一般健康问卷（GHQ - 28）和SF - 36健康调查问卷的心理健康（MH(1 - 5)）维度，评估因疑似缺血性心脏病入院患者的心理健康状况，并比较这两种问卷在该人群中的心理测量特性。
对185例因疑似缺血性心脏病连续入院的患者进行了一项研究，这些患者被分为四组：急性心肌梗死（AMI）、不稳定型心绞痛、非缺血性心脏病以及非心脏病情况。通过GHQ - 28和SF - 36的MH 1 - 5子量表评估他们的心理健康状况；通过将每种工具与社会人口统计学（年龄、性别、社会阶层和教育水平）以及临床（合并症、危险因素、诊断组和疾病背景）变量进行关联分析结果的有效性。研究了每种工具与SF - 36其他子量表的相关性。通过Cronbach's alpha测量内部一致性，同时测量项目内部一致性和项目区分效度。
在研究人群中，71.9%为男性，平均年龄为60.2岁（标准差：10.4）。33.5%的诊断为AMI，37.8%为不稳定型心绞痛。对于所有研究的变量，两种工具的得分排序方式相同，女性和最弱势社会阶层的得分明显更差。没有一个量表在诊断组或合并症存在方面有区分能力。然而，观察到与危险因素呈线性关系。GHQ - 对于所有研究的变量，两种工具的得分排序方式相同，女性和最弱势社会阶层的得分明显更差。没有一个量表在诊断组或合并症存在方面有区分能力。然而，观察到与危险因素呈线性关系。GHQ - 28的Cronbach's alpha为0.95，MH 1 - 5的为0.80。与其他维度的相关性显示，GHQ - 28的范围为 - 0.35至 - 0.61，MH 1 - 5的为0.26至0.61。在两种工具中，这些相关性在活力和社会功能子量表中最高。
SF - 36的MH 1 - 5量表和GHQ - 28对心理健康的主观感知测量方式相似。然而，由于MH 1 - 5问卷较短，在日常心脏病学实践中引入应该在管理上更容易。
