Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Title:
The composite scale of morningness for chronotype estimation in Portuguese older adults: Psychometric properties and cutoff scores
Publication year: 2019

Abstract/Results: ABSTRACT:
INTRODUCTION:
Chronotype refers to the individual differences that exist in the timing of circadian rhythms (e.g., core body temperature, sleep-wake cycle). The Composite Scale of Morningness (CSM) is one of the most widely used measures to estimate chronotype. Despite the importance of accurate chronotype assessments, the psychometric properties of the CSM are not sufficiently explored in older adults. The aim of this study was to examine reliability and validity data of the Portuguese version of the CSM, and to obtain cut-off points (based on percentiles), with a sample of older adults.
MATERIALS AND METHODS:
The sample comprised 522 participants (55% women) with ages between 65 and 95 years (M = 71.40; SD = 5.69), and up to 19 years of formal education (M = 7.10; SD = 4.56). After providing informed consent, all participants completed the CSM. So as to obtain validity data, participants also completed the Basic Scale on Insomnia symptoms and Quality of Sleep (BaSIQS), and questions concerning sleep schedules, and based on the latter the formula of the Mean Sleep point on Free days - sleep corrected (MSFsc) was used to estimate chronotype.
RESULTS:
Regarding the scale's reliability, an alpha value of 0.81 was obtained. All items appeared to contribute to the scale's internal consistency, as removing items would reduce Cronbach's Alpha. The corrected item-total correlations assumed appropriate values (0.33 - 0.60). CSM scores showed a normal distribution, ranging from 19 to 54, M=39.06 (SD = 6.18). Concerning the scale's validity, a non-significant correlation (r = -0.07; p = 0.25) was observed between CSM scores and BaSIQS scores (discriminant validity). Significant correlations were obtained between CSM scores and sleep schedule variables (convergent validity), ranging between -0.34 and -0.79 (i.e., higher morningness scores were accompanied by earlier sleep-wake schedules), and between CSM scores and MSFsc, r = -0.532, p < 0.001. Cut-off points based on P10, P25, P75, and P90, were obtained.
CONCLUSIONS:
The Portuguese version of the CSM seems to be a valid and reliable measure for chronotype assessment in older adults. Internal consistency analyses suggest that the CSM is a consistent and homogeneous scale in this age group. Validity analyses revealed that the CSM significantly correlates with measures of related constructs (sleep schedules and mid sleep point), whilst presenting a non-significant correlation with a measure of a less related construct (sleep quality). CSM mean scores and cut-off scores were higher than those generally reported for young adults in agreement with the advancing circadian system phase with age.

Abstract/Results: ABSTRACT:
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 a = 0.85) and concurrent validity (correlations above 0.76). This new reliable scale should facilitate future research.

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

Abstract/Results: ABSTRACT:
Introduction:
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.
Methods:
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.
Results:
Brislin’s back-translation model was performed to translate a Chinese version of the NDE-C scale and internal consistency (the Cronbach’s a value for the total group = 0.846) as well as the confirmatory factor analysis was conducted.
Discussion:
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.
