Death fear is the main subject in thanatology. Several researchers have defined different reasons for fear of death. This study aimed to explore the performance of the Farsi version of the Reasons for Death Fear Scale (RDFS) among a convenience sample of Iranian nurses ( = 106).
The nurses were selected by the convenience sampling method and were asked to complete the RDFS, Death Concern Scale, Collett-Lester Fear of Death Scale, Death Anxiety Scale, Death Depression Scale, and Death Obsession Scale.
For the RDFS, the Cronbach's coefficient was 0.90, and the 2-week test-retest reliability was 0.64. The RDFS was correlated at 0.34, 0.39, 0.50, 0.35, and 0.39 to the above-mentioned five scales, indicating its good construct and criterion-related validity. Based on the exploratory factor analysis, the RDFS-identified four factors accounted for 66.20% of the variance and were labeled as "Fear of Pain and Punishment," "Fear of Losing Worldly Involvements," "Religious Transgressions and Failures," and "Parting from Loved Ones."
The RDFS presents good validity and reliability and can be used in clinical and research settings in Iran.
对死亡的恐惧是死亡学的主要研究内容。几位研究人员已经明确了对死亡恐惧的不同原因。本研究旨在探讨波斯语版死亡恐惧原因量表（RDFS）在伊朗护士便利样本（n = 106）中的表现。
采用便利抽样法选取护士，并要求他们完成RDFS、死亡关注量表、科利特 - 莱斯特死亡恐惧量表、死亡焦虑量表、死亡抑郁量表和死亡痴迷量表。
对于RDFS，克朗巴赫α系数为0.90，两周重测信度为0.64。RDFS与上述五个量表的相关性分别为0.34、0.39、0.50、0.35和0.39，表明其具有良好的结构效度和效标关联效度。基于探索性因素分析，RDFS确定的四个因素解释了66.20%的方差变异，并被标记为“对痛苦和惩罚的恐惧”、“对失去世俗事务的恐惧”、“宗教违规和失败”以及“与亲人分离”。
RDFS具有良好的效度和信度，可用于伊朗的临床和研究环境。
