An Examination of Psychometric Characteristics and Factor Structure of Death Anxiety Scale Within a Sample of Iranian Patients With Heart Disease

Abstract

Background and aims: Despite a substantial body of work examining the role of death anxiety (DA) in an individual’s quality of life, there is a lack of valid and standardized instruments that could measure this construct for patients with coronary heart disease (CHD). The objective of this study was to examine the psychometric characteristics and factor structure of the Templer Death Anxiety Scale (TDAS) within a sample of Iranian patients who had experienced acute myocardial infarction (AMI). Methods: In this study, 584 patients with CHD completed the TDAS. A principal components analysis evaluated dimensionality of the measuring instrument. Reliability and validity were assessed.
