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 ( = 106).
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).
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 α 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.
The DDS has good validity and reliability, and it can use in clinical and research settings.
死亡抑郁是死亡及临终过程中的一个重要组成部分。死亡抑郁是死亡的第二个要素。抑郁是死亡困扰的重要特征之一。本研究的目的是在一个由106名伊朗护士组成的便利样本中，探索波斯语版死亡抑郁量表的表现。
采用便利抽样法选取护士，并让他们完成死亡抑郁量表（DDS）、死亡担忧量表（DCS）、科利特 - 莱斯特死亡恐惧量表（CLFDS）、死亡恐惧原因量表（RDFS）、坦普勒死亡焦虑量表（DAS）和死亡痴迷量表（DOS）。
对DDS进行探索性因子分析的结果确定了4个因子（方差贡献率为56.16%）。因子1标记为“死亡悲伤”，因子2标记为“死亡终结/结束与死亡恐惧/害怕”，因子3标记为“死亡绝望与死亡抑郁”，因子4标记为“死亡孤独”。克朗巴赫α系数为0.84，斯皮尔曼 - 布朗系数为0.85，古特曼折半系数为0.81。DDS与DCS的相关系数为0.40，与CLFDS的相关系数为0.39，与DAS的相关系数为0.50，与RDFS的相关系数为0.35，与DOS的相关系数为0.44，表明具有良好的结构效度和效标效度。DDS与其他量表的同时效度显著。
DDS具有良好的效度和信度，可用于临床和研究环境。
