Abstract

Purpose: The aim of this study was to validate a Persian version of the Cardiac Depression Scale (CDS) in Iranian patients with acute myocardial infarction (AMI). Methods: The CDS was forward translated from English into Persian and back-translated to English. Validity was assessed using face, content, and construct validity. Also Cronbach's alpha (α), theta (θ), and McDonald's omega coefficient were used to evaluate the reliability. Results: Construct validity of the scale showed two factors with eigenvalues greater than one. The Cronbach's α, θ, McDonald's omega, and construct reliability were greater than .70. Conclusion: The Persian version of the CDS has a two-factor structure (i.e., death anxiety and life satisfaction) and has acceptable reliability and validity. Therefore, the validated instrument can be used in future studies to assess depression in patients with AMI in Iranians. © 2018 Springer Publishing Company.
