This study aimed to evaluate the validity and reliability of the Persian version of Death Anxiety Scale-Extended (DAS-E). A total of 507 patients with end-stage renal disease completed the DAS-E. The factor structure of the scale was evaluated using exploratory factor analysis with an oblique rotation and confirmatory factor analysis. The content and construct validity of the DAS-E were assessed. Average variance extracted, maximum shared squared variance, and average shared squared variance were estimated to assess discriminant and convergent validity. Reliability was assessed using Cronbach’s alpha coefficient (α = .839 and .831), composite reliability (CR = .845 and .832), Theta (θ = .893 and .867), and McDonald Omega (Ω = .796 and .743). The analysis indicated a two-factor solution. Reliability and discriminant validity of the factors was established. Findings revealed that the present scale was a valid and reliable instrument that can be used in assessment of death anxiety in Iranian patients with end-stage renal disease.

Introduction: There has been an increasing awareness on the end of life care for end stage renal disease (ESRD) patients and patients’ factors have been identified as pivotal elements in directing its implementation. Questionnaire has been a useful tool by researchers to assess on patients’ knowledge, perceptions and preferences on end of life care. However, up to date, there is no validated questionnaire developed in Malaysia for such purposes. Thus, this study aims to develop and validate questionnaires on end of life care knowledge, perceptions and preferences among ESRD patients in Kuantan. Materials and method: A cross-sectional study among haemodialysis (HD) patients aged 18 and above from 14 out-patient HD centres was performed. This study was divided into 4 phases i) developing the questionnaire involving related specialists and pre testing, ii) improving and editing the questionnaire and redistribution to 50 respondents for the pilot study, iii) factor analysis and iv) internal consistency reliability testing of the questionnaire.  Results:  The result of Factor analysis with Varimax rotation performed identified 3 domains for the 41 items, with 10 to 20 items in each domain. All the 41 analyzed items had a good factor loading of more than 0.4 with the lowest value of 0.421 and were nicely fit into 3 respective domains; knowledge, perception and preference. Internal consistency reliability analysis performed indicates that Cronbach’s α was between 0.5 to 0.7 for all factors which were higher than the level set for this study which is 0.5. Conclusion: The questionnaire is successfully validated and considered as a useful tool to be used. Nonetheless, improvement will still be necessary from time to time to ensure its relevance especially if it is to be used by different populations or countries of different background than Malaysia.

Abstract BackgroundAdherence to a complex therapeutic regimen is crucial to maintain the quality of life of patients receiving haemodialysis. End Stage Renal Disease Adherence Questionnaire (ESRD-AQ) is a valid and most widely used instrument to assess all dimensions of treatment adherence among patients receiving in-center haemodialysis. Though the precise evaluation is fundamental, availability of valid and reliable instruments to evaluate treatment adherence is limited in Sri Lanka. Therefore, the purpose of this study was to evaluate the psychometric properties of Sinhala translated version of ESRD-AQ.MethodsThe translation and cultural adaptation of ESRD-AQ underwent forward and back translation, expert committee consolidation and pretesting among patients (n=10). Face and content validity were evaluated with a panel of experts (n=6) and group of patients (n=10). Confirmatory Factor Analysis (CFA) was performed to evaluate construct validity of two subscales of SINESRD-AQ. Subsequent Categorical Principal Component Analysis (CATPCA) was performed to identify a more parsimonious dimensionality to assess treatment adherence behaviors among patients. Ethical approval was obtained from the Ethics Review Committee, Faculty of Medical Sciences, University of Sri Jayewardenepura and Teaching Hospital, Kurunegala, Sri Lanka. ResultsA total of 150 patients with mean age of 54.08±10.78 (±SD) years were included. Majority were males (72.7%). Excellent face and content validity of SINESRD-AQ was reported. The CFA of two subscales of ESRD-AQ demonstrated barely acceptable model fit (SRMR=0.120, CFI=0.913, GFI=0.997, AGFI=0.996, NNFI=0.896). Subsequent CATPCA revealed new dimensionality with five components explaining 74% of the total variance. Convergent validity of new dimensionality was confirmed with Composite Reliability (CR) and Average Variance Extracted (AVE) with the values greater than 0.7 and 0.5 respectively. According to the Fornell Larcker criterion (1971), the square root of AVEs of components were greater than the inter component correlations and heterotrait-monotrait values were less than the threshold of 0.85 demonstrated the discriminant validity of new dimensionality.ConclusionSINESRD-AQ is a valid and a reliable instrument to assess treatment adherence behaviors among Sinhala speaking patients receiving haemodialysis in Sri Lanka. A follow-up CFA is to be performed to confirm the revised dimensionality of SINESRD-AQ.
