Death concern is a conscious contemplation of the reality of death combined with a negative evaluation of that reality. The Death Concern Scale (DCS) is related to thinking, and death fear or anxiety about death. The aim of the present study was to develop a Farsi version of the DCS and to explore its psychometric properties in a sample of Iranian nurses.
A cross-sectional study was conducted to investigate the reliability, validity, and factorial structure of the Farsi version of the DCS in a convenience sample of 106 Iranian nurses in two hospitals in Tehran, Iran. The nurses completed the DCS, the Collett-Lester Fear of Death Scale (CLFDS), the Death Anxiety Scale (DAS), the Reasons for Death Fear Scale (RDFS), the Death Depression Scale (DDS), and the Death Obsession Scale (DOS).
For the DCS, Cronbach's α was 0.77, the Spearman-Brown coefficient 0.63, the Guttman split-half coefficient 0.62, and two-week test-retest reliability 0.77. The DCS correlated at 0.51 with the CLFDS, 0.52 with the DAS, 0.34 with the RDFS, 0.40 with the DDS, and 0.48 with the DOS, indicating good construct and criterion-related validity. The results of an exploratory factor analysis for the DCS identified seven factors, accounting for 64.30% of the variance and indicating considerable heterogeneity in the content of the items.
The Farsi version of the DCS has good validity and reliability, and it can be used in clinical, educational, and research settings to assess death concerns in the Iranian society.
对死亡的关注是对死亡现实的有意识思考，并伴有对该现实的负面评价。死亡关注量表（DCS）与思考以及对死亡的恐惧或焦虑有关。本研究的目的是开发DCS的波斯语版本，并在伊朗护士样本中探讨其心理测量特性。
进行了一项横断面研究，以调查DCS波斯语版本在伊朗德黑兰两家医院的106名伊朗护士便利样本中的信度、效度和因子结构。护士们完成了DCS、科利特 - 莱斯特死亡恐惧量表（CLFDS）、死亡焦虑量表（DAS）、死亡恐惧原因量表（RDFS）、死亡抑郁量表（DDS）和死亡痴迷量表（DOS）。
对于DCS，克朗巴哈α系数为0.77，斯皮尔曼 - 布朗系数为0.63，古特曼折半系数为0.62，两周重测信度为0.77。DCS与CLFDS的相关性为0.51，与DAS的相关性为0.52，与RDFS的相关性为0.34，与DDS的相关性为0.40，与DOS的相关性为0.48，表明具有良好的结构效度和效标关联效度。DCS的探索性因子分析结果确定了七个因子，解释了64.30%的方差，表明项目内容存在相当大的异质性。
DCS的波斯语版本具有良好的效度和信度，可用于临床、教育和研究环境，以评估伊朗社会对死亡的关注。
