Purpose:
Patients with coronary heart disease (CHD) will have a series of sexual problems, and their sexual life quality can be affected. However, a standardised evaluation tool for patients with CHD was lacking. Therefore, this study aimed to develop a sexual life quality questionnaire for patients with CHD and to evaluate its psychometric properties.
Methods:
Based on previous phenomenological studies, literature analysis and group discussion, questionnaire items were formed. After two rounds of expert consultation and pre-survey, the questionnaire items were modified. Items were screened by item analysis. Exploratory factor analysis and confirmatory factor analysis were used to explore and confirm the structure of the questionnaire. Content validity and criterion validity were evaluated using the expert consultation and correlation analysis, respectively. The questionnaire reliability was evaluated using internal consistency, split half reliability, and test-retest reliability.
Results:
The sexual life quality questionnaire of patients with CHD was developed, which included two versions: male version and female version. The male version of the questionnaire contains 3 dimensions and 20 items, while the female version contains 3 dimensions and 17 items. After reliability and validity test, the two versions of the questionnaire have good reliability and validity.
Conclusions:
In this study, the sexual life quality questionnaire of patients with CHD was developed and its psychometric properties were confirmed, which can be used to evaluate the sexual life quality of patients with CHD.
Implications For Clinical Practice:
The development of a sexual life quality evaluation tool for patients with coronary heart disease to provide objective and quantitative tools for clinical staff to evaluate patients' sexual life status.
Patient Contribution:
Patients were invited to participate in a questionnaire survey for this study.

Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
