The patients' sexual life after a myocardial infarction is important for his/her quality of life. In spite of this, many patients are in doubt regarding their sex life after a myocardial infarction (MI) and the sexual information received, and counselling from health care providers has been seen to be insufficient. The purpose of this study was to evaluate the psychometric properties of 'The 25-item Sex after MI Knowledge Test' in a Swedish context. A convenience sample was recruited. The scale was translated into Swedish and completed by 79 former patients from The Heart and Lung Patients' National Association on two occasions, with an interval of 2 weeks. The scale was tested for face and content validity, internal consistency and test-retest reliability. The result in this study indicates that the instrument has good face and content validity and displayed a moderate internal consistency (alpha 0.61). The instrument showed some level of instability in test-retest reliability with 60% of the items presenting moderate or strong agreement between the test and retest. Further studies that use this instrument in larger and more diverse samples are thus needed.
心肌梗死后患者的性生活对其生活质量至关重要。尽管如此，许多患者对心肌梗死后的性生活以及所获得的性信息心存疑虑，而且医疗保健提供者提供的咨询被认为是不足的。本研究的目的是在瑞典背景下评估“心肌梗死后25项性知识测试”的心理测量特性。招募了一个便利样本。该量表被翻译成瑞典语，来自全国心肺疾病患者协会的79名 former patients 分两次完成该量表，间隔为2周。对该量表进行了表面效度和内容效度、内部一致性以及重测信度的测试。本研究结果表明，该工具具有良好的表面效度和内容效度，并显示出中等程度的内部一致性（α系数为0.61）。该工具在重测信度方面表现出一定程度的不稳定性，60%的项目在测试和重测之间呈现出中等或高度一致性。因此，需要在更大、更多样化的样本中使用该工具进行进一步研究。
