Hypothesis
The CDI-SF would show satisfactory factorial validity and reliability.
Conclusion
The study supports the CDI-SF as a valid and reliable measure of cardiac distress in the Chinese context.
Supporting Evidence
- The CDI-SF showed excellent composite reliability (ω = .92).
- The 1-factor model showed adequate model fit.
- The CDI-SF factor was negatively associated with age (r = –.21, p <.01).
- The CDI-SF showed positive correlations with impact of event, depression, and burnout.
- The CDI-SF showed negative correlations with resilience and quality of life.
Takeaway
This study created a short questionnaire to help doctors understand how heart patients feel emotionally, which can help them get better care.
Methodology
227 patients with cardiac diseases completed the CDI-SF and other validated measures; exploratory factor analysis and partial correlation analysis were used.
Potential Biases
Non-random sampling design and low response rate may introduce bias.
Limitations
The sample was recruited via convenience sampling in a single clinic, which may affect representativeness.
Participant Demographics
Mean age was 59.2 years, with 73.1% male participants.
