The near-death-experiences features

14 December, 2020

In the scope of the research project “Characterization of “Near-Death Experiences” through the comparison of experiencers and non-experiencers’ particularities: inter-individual differences in cognitive characteristics and susceptibility to false memories” supported by the BIAL Foundation, the research team of the University of Liège led by Steven Laureys published the paper The Near-Death Experience Content (NDE-C) scale: Development and psychometric validation in the journal Consciousness and Cognition.

As interest grows in near-death experiences (NDEs), it is increasingly important to accurately identify them to facilitate empirical research and reproducibility among assessors. We aimed (1) to reassess the psychometric properties of the NDE scale developed by Greyson (1983) and (2) to validate the Near-Death Experience Content (NDE-C) scale that quantifies NDEs in a more complete way. Internal consistency, construct and concurrent validity analyses were performed on the NDE scale. Based on those results and the most recent empirical evidence, we then developed a new 20-item scale. Internal consistency, explanatory and confirmatory factor, concurrent and discriminant validity analyses were conducted. Results revealed (1) a series of weaknesses in the NDE scale, (2) a 5-factor structure covering relevant dimensions and the very good psychometric properties of the NDE-C scale, including very good internal consistency (Cronbach α = 0.85) and concurrent validity (correlations above 0.76). This new reliable scale should facilitate future research”.
