Abstract

Background: This study aimed to evaluate the psychometric evaluation of heart failure somatic perception scale (HFSPS) in Iranian heart failure patients. Materials and methods: A total of 220 heart failure (HF) patients were enroled in the study. Data gathering was conducted via consecutive sampling from August 2022 to April 2023. Face validity, content validity, construct validity, and internal consistency were used to evaluate the validity and reliability of the Persian version of the HFSPS. Construct validity was done through confirmatory factor analysis and convergent validity. Convergent validity between HFSPS and symptom status questionnaire-heart failure was measured using Pearson’s correlation coefficient. Cronbach’s alpha and Macdonald’s omega coefficient were used to evaluate the reliability of instruments. Results: A total of 220 HF patients participated in this study. Their mean age was 66.46 (SD=11.40). Among the participants, 70% were men. The results of the confirmatory factor analysis evaluation showed the goodness of fit indices of the final HFSPS model after modification was within an acceptable range (χ2=306.18 P<0.001, Minimum Discrepancy Function Divided by Degrees of Freedom=2.47, Comparative of Fit Index=0.91, Tucker-Lewis index=0.90, Adjusted goodness of fit index=0.81, Parsimonious norm fit index=0.70, root mean square error of approximation=0.082). Convergent validity between HFSPS and symptom status questionnaire-heart failure indicated a positive…

How strong is the evidence?

Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 220 participants or records.
