Self-Efficacy Scale Among Iranian Cardiovascular Patients: Persian Translation, Validity, and Reliability Assessment

Background and Purpose: The purpose of this study was to translate the Sherer Self-Efficacy Scale into Persian and assess its psychometric properties among Iranian patients with cardiovascular diseases. Methods: This crosssectional research design was done in 2019. The Persian version of the Self-Efficacy Scale was completed by 400 cardiovascular patients. The scale's reliability and validity (face, content, and construct) were evaluated. Results: A four-factor structure of the Self-Efficacy Scale explained 39.22% of the total variance. Additionally, this Scale demonstrated good construct validity on the basis of the confirmatory factor analysis's findings. The reliability of the scale was assessed and proved with coefficient alpha, McDonald's omega, and ICC. Conclusions: The Persian version of the Self-Efficacy Scale had acceptable reliability and validity. This Scale could be used by Iranian patients with cardiovascular disease to determine how effective they are at treating themselves.
