Cronbach's ? reliability, concurrent validity, and factorial structure of the Death Depression Scale in an Iranian hospital staff sample.

ABSTRACT: Objective:Death depression is an important component in the process of death and dying. Death depression is the second element of death. Depression is one of the important features in death distress. The aim of this study was to explore the performance of the Farsi version of the Death Depression Scale with an Iranian convenience sample of nurses (n = 106). Methods:Nurses were selected using a convenience sampling method, and completed the Death Depression Scale (DDS), Death Concern Scale (DCS), Collett-Lester Fear of Death Scale (CLFDS), Reasons for Death Fear Scale (RDFS), Templer's Death Anxiety Scale (DAS), and Death Obsession Scale (DOS). Results:The results of exploratory factor analysis on DDS identified 4 factors (56.16% of variance). Factor 1 labeled "Death sadness", Factor 2 labeled "Death finality/end and Death dread/fear", Factor 3 labeled "Death despair and Death depression", and Factor 4 labeled "Death loneliness". Cronbach's ? coefficient was 0.84, Spearman-Brown coefficient 0.85, and Guttman Split-Half coefficient 0.81 The DDS correlated 0.40 with the DCS, 0.39 with the CLFDS, 0.50 with the DAS, 0.35 with the RDFS, and 0.44 with the DOS, indicating good construct and criterion-related validity. Concurrent validity for the DDS with the other scales were significant. Conclusions:The DDS has good validity and reliability, and it can use in clinical and research settings.

Project description:BackgroundThis study aimed to assess the factorial validity and reliability of the Pandemic Stressor Scale (PaSS), a new measure to assess the severity of distress for different stressors relevant during a pandemic or epidemic.MethodsThe PaSS was administered in N = 2760 German participants. Exploratory factor analysis was used to extract factors. The factor structure obtained in the German sample was examined in N = 1021 Austrian participants using confirmatory factor analysis. χ2, RMSEA, SRMR, CFI, TLI were assessed as global goodness of fit indices for two models (Model 1: nine-factor model; Model 2: nine-factor model combined with a second-order general factor). We additionally assessed factor loadings, communalities, factor reliability, discriminant validity as local fit indices. Internal consistency, item discrimination, and item difficulty were assessed as additional test quality criteria.ResultsThe results of the exploratory factor analysis suggested a nine-factor solution with factor loadings accounting for 50.4% of the total variance (Factor 1 'Problems with Childcare', Factor 2 'Work-related Problems', Factor 3 'Restricted Face-to-Face Contact', Factor 4 'Burden of Infection ', Factor 5 'Crisis Management and Communication', Factor 6 'Difficult Housing Condition', Factor 7 'Fear of Infection', Factor 8 'Restricted Access to Resources', Factor 9 'Restricted Activity'). The confirmatory factor analysis showed a sufficient global fit for both tested models (Model 1: χ2 (369, N = 1021) = 1443.28, p < .001, RMSEA = .053, SRMR = .055, CFI = .919, TLI = .904; Model 2: χ2 (396, N = 1021) = 1948.51, p < .001, RMSEA = .062, SRMR = .074, CFI = .883, TLI = .871). The results of the chi-square difference test indicated a significantly better model-fit of Model 1 compared to Model 2 (∆χ2 (27, N = 1021) = 505.23, p < .001). Local goodness of fit indices were comparable for both tested models. We found good factor reliabilities for all factors and moderate to large factor loadings of the items as indicators. In Model 2, four first-order factors showed small factor loadings on the second-order general factor.ConclusionThe Pandemic Stressor Scale showed sufficient factorial validity for the nine measured domains of stressors during the current COVID-19 pandemic.
