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…
Confirmatory Factor Analysis of the Valencia Scale on Attitudes and Beliefs Toward Hypnosis, Therapist Version
2008
Health professionals' beliefs and attitudes toward hypnosis may make them reluctant to use it or even to foster misapplications and iatrogenic uses of hypnosis. The Valencia Scale on Attitudes and Beliefs toward Hypnosis-Therapist version (VSABH-T) is a specific instrument to evaluate therapists' attitudes and beliefs. The aims of this study are to evaluate the 8-factor structure of the VSABH-T proposed from a confirmatory perspective. The sample comprised 1,661 licensed psychologists who are members of the Spanish Psychological Association for the initial test and 787 for the retest. Results confirmed the 8-factor structure obtained in a previous exploratory study, namely: Fear, Memory, He…
Permanently online and permanently connected : development and validation of the Online Vigilance Scale
2017
Smartphones and other mobile devices have fundamentally changed patterns of Internet use in everyday life by making online access constantly available. The present paper offers a theoretical explication and empirical assessment of the concept of online vigilance, referring to users' permanent cognitive orientation towards online content and communication as well as their disposition to exploit these options constantly. Based on four studies, a validated and reliable self-report measure of online vigilance was developed. In combination, the results suggest that the Online Vigilance Scale (OVS) shows a stable factor structure in various contexts and user populations and provides future work i…
Sensor acceptance model:measuring patient acceptance of wearable sensors
2008
Summary Objectives: This project focuses on how patients respond to wearable biomedical sensors, since patient acceptance of this type of monitoring technology is essential for enhancing the quality of the data being measured. There is a lack of validated questionnaires measuring patient acceptance of telemedical solutions, and little information is known of how patients evaluate the use of wearable sensors. Methods: In information systems research, surveys are commonly used to evaluate the user satisfaction of software programs. Based on this tradition and adding measures of patient satisfaction and health-related quality of life (HRQoL), a Sensor Acceptance Model is developed. The model i…
Measuring consciousness in dreams: the lucidity and consciousness in dreams scale.
2013
In this article, we present results from an interdisciplinary research project aimed at assessing consciousness in dreams. For this purpose, we compared lucid dreams with normal non-lucid dreams from REM sleep. Both lucid and non-lucid dreams are an important contrast condition for theories of waking consciousness, giving valuable insights into the structure of conscious experience and its neural correlates during sleep. However, the precise differences between lucid and non-lucid dreams remain poorly understood. The construction of the Lucidity and Consciousness in Dreams scale (LuCiD) was based on theoretical considerations and empirical observations. Exploratory factor analysis of the da…
Types of Triggers in Migraine - Factor Structure of the Headache Triggers Sensitivity and Avoidance Questionnaire and Development of a New Short Form…
2020
OBJECTIVE: To examine the factor structure of the Headache Triggers Sensitivity and Avoidance Questionnaire (HTSAQ) and its German version (HTSAQ-G), in order to identify potential different types of triggers. Furthermore, a short form of the questionnaire was developed. BACKGROUND: The HTSAQ includes 24 of the most commonly reported headache triggers (eg, stress, odors, lack of sleep). Both the HTSAQ and HTSAQ-G appeared to be reliable and valid measures of sensitivity to and avoidance of headache triggers. METHODS: In a cross-country collaboration, data from 2 cross-sectional studies including N = 391 individuals diagnosed with migraine from Australia (n = 222) and Germany (n = 169) were …
Development and Validation of the AdT-Physio Scale: A Tool to Assess Adherence and Perception of Physical Therapist Intervention in Patients With Cys…
2019
Abstract Objective The purpose of this study was to develop a scale to measure patient adherence to physical therapist intervention and to report psychometric properties in patients with cystic fibrosis (CF). Methods This observational, multicenter, qualitative, and cross-sectional study was divided into 2 phases: development of scale items (content validity) and assessment of psychometric properties (construct validity, reliability, and convergent/discriminant validity). Recruited were 121 patients with CF (aged ≥16 years). Sociodemographic characteristics, lung function testing, Coping with Stress Self-Efficacy, brief Coping Orientation to Problems Experienced inventory, and the scale of …
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…
Mini-Mental Adjustment to Cancer Scale: Construct validation in Spanish breast cancer patients.
2018
Abstract Objective The Mini-Mental Adjustment to Cancer Scale (MiniMAC) is widely used to evaluate cancer patients' psychological responses to diagnosis and treatment. Validation studies of the scale have shown inconsistency in the obtained factor structures. The aim of this study was to explore the factor structure, using Confirmatory Factor Analysis (CFA), and other psychometric properties of the MiniMAC in Spanish breast cancer patients. Methods A sample of 368 women with breast cancer completed the MiniMAC and the 18 items version of the Brief Symptom Inventory (BSI-18). Results The original pentafactorial model and three additional models derived from the empirical research -two first-…
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…
