This paper reports our experience with the use of an improved self-administered questionnaire for assessing quality of life (QOL) after acute myocardial infarction. The modified questionnaire significantly increased the proportion of patients able to answer all questions from 84%-92%. The additional questions in the improved questionnaire increased the total variance explained by the Emotional, Physical and Social QOL factors from 65.8%-66.5%. Internal consistency and construct validity were assessed and found to be high. Overall, we have found that this improved questionnaire is easy to administer and that it possesses desirable properties of validity and reliability.
本文报告了我们使用一种改进的自填式问卷评估急性心肌梗死后生活质量（QOL）的经验。修改后的问卷显著提高了能够回答所有问题的患者比例，从84%提高到了92%。改进后的问卷中的额外问题使情感、身体和社会生活质量因素所解释的总方差从65.8%提高到了66.5%。对内部一致性和结构效度进行了评估，发现其较高。总体而言，我们发现这种改进后的问卷易于实施，并且具有理想的效度和信度。
