Content Of Near-death Experiences Research Articles

Chinese translation and validation of the Near-Death Experience Content scale.

In recent years, a growing number of near-death experience (NDE) testimonies have been collected worldwide due to an increasing interest in research on this phenomenon. China has many patients who survive life-threatening situations, leaving over much data on NDEs to be collected for research. In the historical context of Eastern civilization, many mentally controlled practices in China can also lead to "NDEs-like" (e.g., meditation). This study aimed (1) to translate and validate the recently developed Near-Death Experience Content (NDE-C) scale into Chinese and (2) to quantify and identify NDEs and NDEs-like in China with this new Chinese version of the NDE-C scale. Here, we presented the work that had been performed to translate the NDE-C scale into Chinese and validated this version on 79 NDE testimonies. Brislin's back-translation model was performed to translate a Chinese version of the NDE-C scale and internal consistency (the Cronbach's α value for the total group = 0.846) as well as the confirmatory factor analysis was conducted. Currently, the Chinese version of the NDE-C scale is ready for use in research practice in the context of Eastern culture, to screen people who have experienced an NDEs(-like) and to quantify their subjective experience, promoting further NDEs-related research in China.

The Near-Death Experience Content (NDE-C) scale: Development and psychometric validation.

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.

Near-Death Experiences in patients with locked-in syndrome: Not always a blissful journey

Memories of Near-Death Experiences (NDEs) most often are recounted as emotionally positive events. At present, no satisfactory explanatory model exists to fully account for the rich phenomenology of NDEs following a severe acute brain injury. The particular population of patients with locked-in syndrome (LIS) provides a unique opportunity to study NDEs following infratentorial brain lesions. We here retrospectively characterized the content of NDEs in 8 patients with LIS caused by an acute brainstem lesion (i.e., "LIS NDEs") and 23 NDE experiencers after coma with supratentorial lesions (i.e., "classical NDEs"). Compared to "classical NDEs", "LIS NDEs" less frequently experienced a feeling of peacefulness or well-being. It could be hypothesized that NDEs containing less positive emotions might have a specific neuroanatomical substrate related to impaired pontine/paralimbic connectivity or alternatively might be related to the emotional distress caused by the presence of conscious awareness in a paralyzed body.

Using computational linguistics to understand near-death experiences: Concurrent validity for the Near Death Experience Scale.

Latent semantic analysis—a technique to quantify qualitative data—was used on a large dataset of near death experience (NDE) accounts for which a sizable portion also had scores on Greyson’s NDE Scale. Given previous research with the NDE Scale showing there is a “core NDE” comprised of a probabilistic hierarchy of cognitive, affective, transcendental, and paranormal components, we hypothesized that there would be a similar hierarchy of experiential components reflected in NDErs’ verbal accounts as evidenced by a significant relation between NDE intensity and NDE content. Predictions were largely confirmed. The verbal accounts associated with True NDEs, defined by above median scores on the NDE Scale, stood out as highly structured episodes with a clear framework comprised of seven major linguistic clusters of descriptors. Four of the linguistic factors included transcendent or paranormal themes, whereas the remaining three factors tended to focus on both vague and specific references to physiological or environmental elements. The results are argued to support concurrent validity issues with Greyson’s NDE Scale and illustrate how latent semantic analysis (LSA) and related approaches can be used to study qualitative information across topics relevant to the many facets of theory-building in consciousness studies.

About the continuity of our consciousness.

Some people who have survived a life-threatening crisis report an extraordinary experience. Near-death experiences (NDE) occur with increasing frequency because of improved survival rates resulting from modern techniques of resuscitation. The content of NDE and the effects on patients seem similar worldwide, across all cultures and times. The subjective nature and absence of a frame of reference for this experience lead to individual, cultural, and religious factors determining the vocabulary used to describe and interpret the experience. NDE can be defined as the reported memory of the whole of impressions during a special state of consciousness, including a number of special elements such as out-of-body experience, pleasant feelings, seeing a tunnel, a light, deceased relatives, or a life review. Many circumstances are described during which NDE are reported, such as cardiac arrest (clinical death), shock after loss of blood, traumatic brain injury or intra-cerebral haemorrhage, near-drowning or asphyxia, but also in serious diseases not immediately life-threatening. Similar experiences to near-death ones can occur during the terminal phase of illness, and are called deathbed visions. Furthermore, identical experiences, so-called “fear-death” experiences, are mainly reported after situations in which death seemed unavoidable like serious traffic or mountaineering accidents. The NDE is transformational, causing profound changes of life-insight and loss of the fear of death. An NDE seems to be a relatively regularly occurring, and to many physicians an inexplicable phenomenon and hence an ignored result of survival in a critical medical situation.

Risk Management in Hypnotic Recall of Near-Death Experiences

A substantial number of people facing physical and/or psychological crisis report having a near-death experience (NDE) involving a subjectively real experience of an alternate reality. Where NDE content is associated with positive emotions, benefit might be gained by hypnotic recall of the NDE, yet such recall might involve possible risk in the form of reactivation of the original crisis. In this article we describe a study involving hypnotic recall of positive NDEs by one male and five female subjects. We describe in detail some procedures to minimize risk, including a hypnosis protocol.

Hospice nurses' knowledge and attitudes toward the near-death experience

I surveyed 60 hospice nurses regarding their knowledge and attitudes toward the near-death experience (NDE), using Thornburg's Near-Death Phenomena Knowledge and Attitudes Questionnaire. Most hospice nurses had previous work experience with an NDEr. Approximately half the nurses were knowledgeable about the NDE. All participants had a positive attitude toward near-death phenomena and toward caring for an NDEr. Recommendations include near-death phenomena inservice education for hospice nurses and inclusion of NDE content in nursing education programs.
