Abstract

PURPOSE
The purpose of this study was to develop a Cardiovascular Disease Resilience (CDR) scale to evaluate disease specific resilience for recovery.
METHODS
The study was conducted as follows: items generation, and test of validity and reliability. Items were developed via literature review, review of instruments, and data acquired from the interviews. In order to test validity and reliability, seven panels of experts reviewed the preliminary questionnaire and then data were collected from 550 cardiovascular disease patients. Factor analysis, Pearson correlation, ANOVA, and Cronbach's alpha were used to analyze the data.
RESULTS
In the preliminary stage, forty-four items were generated. A reduction to 40 items was accomplished through content validity analysis. Factor analysis extracted 7 factors with a total of 25 items. The CDR items were moderately correlated with the subscales of the CD-RISC (Connor-Davidson Resilience Scale) and the mean score of CDR was associated with quality of life measured with CD-QOL (Cardiovascular Disease Quality of Life). Cronbach's alpha=.84.
CONCLUSION
Content validity, construct validity, criterion validity, and reliability of the CDR were established. The CDR is a reliable and valid instrument which the resilience of cardiovascular disease specific recovery state can be evaluated.
