Confirmatory Factor Analysis of the Valencia Scale of Attitudes and Beliefs Toward Hypnosis–client Version in a Portuguese Sample

2018

Research literature about hypnosis highlights the importance of clients' attitudes and beliefs toward hypnosis because they promote hypnotic responses and may predict the effectiveness of hypnotic interventions as well as minimize iatrogenic effects for clients. This study analyzes the factorial structure and psychometric properties with confirmatory methodology of the Valencia Scale of Attitudes and Beliefs Toward Hypnosis-Client Version, using a Portuguese sample. We expected to replicate the results obtained in previous research conducted with samples from various countries. The Portuguese sample comprised 1,977 participants. We found a structure of 8 factors, with an adequate internal c…

Reliability of Magnetoencephalography and High-Density Electroencephalography Resting-State Functional Connectivity Metrics

2019

Resting-state connectivity, for example, based on magnetoencephalography (MEG) or electroencephalography (EEG), is a widely used method for characterizing brain networks and a promising imaging biomarker. However, there is no established standard as to which method, modality, and analysis variant is preferable and there is only limited knowledge on the reproducibility, an important prerequisite for clinical application. We conducted an MEG-/ high-density (hd)-EEG-study on 22 young healthy adults, who were measured twice in a scan/rescan design after 7 – 2 days. Reliability of resting-state (15 min, eyes-closed) connectivity in source space was calculated via intraclass correlation coefficie…

A Brief Measure for the Assessment of Competence in Coping With Death: The Coping With Death Scale Short Version.

2019

Context. The coping with death competence is of great importance for palliative care professionals, who face daily exposure to death. It can keep them from suffering compassion fatigue and burnout, thus enhancing the quality of the care provided. Despite its relevance, there are only two measures of professionals’ ability to cope with death. Specifically, the Coping with Death Scale (CDS) has repeatedly shown psychometric problems with some of its items. Objective. The aim of this study was to develop and validate a short version of the CDS. Methods. Nine items from the original CDS were chosen for the short version. Two cross-sectional surveys were conducted in Spanish (N ¼ 385) and Argent…

Comparing indirect methods of digit ratio (2D:4D) measurement.

2008

The ratio of the lengths of the second and fourth finger (2D:4D) has been proposed to index prenatal exposure to androgens. Different methods have been utilized to measure digit ratio, however, their measurement precision and economy have not been systematically compared yet. Using different indirect methods (plastic ruler, caliper, computer software), three independent raters measured finger lengths of 60 participants. Generally, measurement precision (intraclass correlation coefficient, technical error of measurement, and relative technical error of measurement) was acceptable for each method. However, precision estimates were highest for the computer software, indicating excellent measur…

Testing the validity of the International Atomic Energy Agency (IAEA) safety culture model

2012

This paper takes the first steps to empirically validate the widely used model of safety culture of the International Atomic Energy Agency (IAEA), composed of five dimensions, further specified by 37 attributes. To do so, three independent and complementary studies are presented. First, 290 students serve to collect evidence about the face validity of the model. Second, 48 experts in organizational behavior judge its content validity. And third, 468 workers in a Spanish nuclear power plant help to reveal how closely the theoretical five-dimensional model can be replicated. Our findings suggest that several attributes of the model may not be related to their corresponding dimensions. Accordi…

Modeling offenses among motorcyclists involved in crashes in Spain.

2013

In relative terms, Spanish motorcyclists are more likely to be involved in crashes than other drivers and this tendency is constantly increasing. The objective of this study is to identify the factors that are related to being an offender in motorcycle accidents. A binary logit model is used to differentiate between offender and non-offender motorcyclists. A motorcyclist was considered to be offender when s/he had committed at least one traffic offense at the moment previous to the crash. The analysis is based on the official accident database of the Spanish general directorate of traffic (DGT) for the 2003–2008 time period. A number of explanatory variables including motorcyclist character…

Arrival-time judgments on multiple-lane streets: the failure to ignore irrelevant traffic

2014

How do road users decide whether or not they have enough time to cross a multiple-lane street with multiple approaching vehicles? Temporal judgments have been investigated for single cars approaching an intersection; however, close to nothing is known about how street crossing decisions are being made when several vehicles are simultaneously approaching in two adjacent lanes. This task is relatively common in urban environments. We report two simulator experiments in which drivers had to judge whether it would be safe to initiate street crossing in such cases. Matching traffic gaps (i.e., the temporal separation between two consecutive vehicles) were presented either with cars approaching o…

Another look at safety climate and safety behavior: deepening the cognitive and social mediator mechanisms.

2012

WOS:000301081700053 (Nº de Acesso Web of Science) “Prémio Científico ISCTE-IUL 2013” In this study, safety climate literature and the theory of planned behavior were combined to explore the cognitive and social mechanisms that mediate the relationship between organizational safety climate and compliance and proactive safety behaviors. The sample consisted of 356 workers from a transportation organization. Using a multiple mediation design, the results revealed that proactive and compliance safety behaviors are explained by different patterns of combinations of individual and situational factors related to safety. On the one hand, the relationship between organizational safety climate and pr…

A correlation linking the predicted mean vote and the mean thermal vote based on an investigation on the human thermal comfort in short-haul domestic…

2015

Abstract The results of an experimental investigation on the human thermal comfort inside the cabin of some Airbus A319 aircrafts during 14 short-haul domestic flights, linking various Italian cities, are presented and used to define a correlation among the predicted mean vote (PMV), a procedure which is commonly used to assess the thermal comfort in inhabited environments, and the equivalent temperature and mean thermal vote (MTV), which are the parameters suggested by the European Standard EN ISO 14505-2 for the evaluation of the thermal environment in vehicles. The measurements of the radiant temperature, air temperature and relative humidity during flights were performed. The air temper…
