Objective: The psychometric properties of a scale should be re-assessed routinely with different samples to ensure its generalizability. The present study aimed to determine the reliability and validity of the Persian Version of Death Depression Scale (DDS) in Iranian patients with Acute Myocardial Infarction (AMI).
Methods: The face validity, content validity and construct validity (i.e. factorial, convergent, and discriminant validity) of the DDS were assessed using a sample of 407 AMI patients. Confirmatory factor analysis was conducted using the ratio chi-square by degrees of freedom (χ2/df), the Goodness-of-fit index (GFI), Comparative Fit Index (CFI), Incremental Fit Index (IFI), Normed Fit Index (NFI), and Root Mean Square Error of Approximation (RMSEA). Convergent and discriminant validity were assessed using average variance extracted (AVE), maximum shared squared variance (MSV), and average shared square variance (ASV). Internal consistency, test–retest, and construct reliability (CR) were used to assess reliability of the Persian Version of DDS.
Results: Based on principle component analysis and consideration of conceptual meaning, a four-factor solution was selected, explaining 75.89% of the total variance. Goodness-of-fit indices (c2(98) = 583.646, p < .05, c2/df= 5.956, GFI = .856, CFI = .902, NFI = .885, IFI = .902, RMSEA (90% C.I.) = .110 (.102 - .119) in the final DDS structure demonstrated the adequacy of the four-domain structure of the DDS. Convergent and discriminant validity was used to assess the construct validity of the DDS. The reliability was greater than .70.
Conclusion: The DDS was found to be a valid and reliable assessment tool for death depression in Iranian patients with AMI. |
