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…
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…
Confabulation: damage to a specific inferior medial prefrontal system
2008
Confabulation, the pathological production of false memories, occurs following a variety of aetiologies involving the frontal lobes, and is frequently held to be underpinned by combined memory and executive deficits. However, the critical frontal regions and specific cognitive deficits involved are unclear. Studies in amnesic patients have associated confabulation with damage to the orbital and ventromedial prefrontal cortices. However, neuroimaging studies have associated memory-control processes which are assumed to underlie confabulation with the right lateral prefrontal cortex. We used a confabulation battery to investigate the occurrence and localisation of confabulation in an unselect…
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 …
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-…
Wording effects and the factor structure of the 12-item General Health Questionnaire (GHQ-12)
2021
The 12-item version of the General Health Questionnaire (GHQ-12) has become a popular screening instrument with which to measure general psychological health in different settings. Previous studies into the factorial structure of the GHQ-12 have mainly supported multifactor solutions, and only a few recent works have shown that the GHQ-12 was best represented by a single substantive factor when method effects associated with negatively worded items were considered. Confirmatory factor analysis was applied to compare competing measurement models from previous research, including correlated traits-correlated methods and correlated traits-correlated uniquenesses approaches, to obtain further e…
The 9-item Bergen Burnout Inventory: Factorial Validity Across Organizations and Measurements of Longitudinal Data
2013
The present study tested the factorial validity of the 9-item Bergen Burnout Inventory (BBI-9) 1) . The BBI-9 is comprised of three core dimensions: (1) exhaustion at work; (2) cynicism toward the meaning of work; and (3) sense of inadequacy at work. The study further investigated whether the three-factor structure of the BBI-9 remains the same across different organizations (group invariance) and measurement time points (time invariance). The factorial group invariance was tested using a cross-sectional design with data pertaining to managers (n=742), and employees working in a bank (n=162), an engineering office (n=236), a public sector organization divided into three service areas: admin…
Relationship Between the Linguistic Environments and Early Bilingual Language Development of Hearing Children in Deaf-parented Families
2013
We explored variation in the linguistic environments of hearing children of Deaf parents and how it was associated with their early bilingual language development. For that purpose we followed up the children's productive vocabulary (measured with the MCDI; MacArthur Communicative Development Inventory) and syntactic complexity (measured with the MLU10; mean length of the 10 longest utterances the child produced during videorecorded play sessions) in both Finnish Sign Language and spoken Finnish between the ages of 12 and 30 months. Additionally, we developed new methodology for describing the linguistic environments of the children (N = 10). Large variation was uncovered in both the amount…
