Studies have this reported the presence of death anxiety, ranging from near-death experiences to physically ill people, to a simple thought about death, as well as when it is associated with states of loneliness. The Templer's Death Anxiety Scale (DAS), based on Eysenk's incubation theory, has been adapted and validated in different contexts and is still insufficient in countries such as Peru. This study aimed to determine the psychometric properties of the DAS, its internal structure, and factorial invariance.
An online scale was used in 1248 Peruvians aged between 18 and 70 years (M= 27.37, SD= 11.29) from all regions. DAS was validated using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), convergent validity, measurement invariance, and internal consistency (reliability).
Psychometric properties were found with adequate values in its structure and validity based on the internal structure through exploratory factor analysis, where it was found that the components of the scale are interrelated and the data matrix is factorizable. model of three specific factors and a general factor is presented, which is consistent with the theory and has practical utility, revealing adequate statistical values that reflect acceptable levels of reliability. Finally, there was fairness according to sex and age group of the scale by means of factorial invariance analysis.
Our results indicate adequate psychometric properties and facilitate a better data collection process for future research.
研究报告了死亡焦虑的存在，范围从濒死体验到身体患病的人，再到对死亡的简单思考，以及与孤独状态相关时的情况。基于艾森克潜伏期理论的坦普勒死亡焦虑量表（DAS）已在不同背景下进行了改编和验证，但在秘鲁等国家仍不够完善。本研究旨在确定DAS的心理测量特性、其内部结构和因素不变性。
对来自秘鲁所有地区的1248名年龄在18至70岁之间（M = 27.37，SD = 11.29）的人使用了在线量表。通过探索性因素分析（EFA）、验证性因素分析（CFA）、收敛效度、测量不变性和内部一致性（信度）对DAS进行了验证。
通过探索性因素分析，基于内部结构在其结构和效度方面发现了具有适当值的心理测量特性，发现量表的各成分相互关联且数据矩阵可进行因子分解。提出了一个包含三个特定因素和一个一般因素的模型，该模型与理论一致且具有实际效用，揭示了反映可接受信度水平的适当统计值。最后，通过因素不变性分析表明该量表在性别和年龄组方面具有公平性。
我们的结果表明该量表具有适当的心理测量特性，并为未来研究促进了更好的数据收集过程。
