The latent structure of the functional dyspepsia symptom complex: A taxometric analysis
2016
OBJECTIVES: Rome III introduced a subdivision of functional dyspepsia (FD) into postprandial distress syndrome and epigastric pain syndrome, characterized by early satiation/postprandial fullness, and epigastric pain/burning, respectively. However, evidence on their degree of overlap is mixed. We aimed to investigate the latent structure of FD to test whether distinguishable symptom-based subgroups exist. METHODS: Consecutive tertiary care Rome II FD patients completed the dyspepsia symptom severity scale. Confirmatory factor analysis (CFA) was used to compare the fit of a single factor model, a correlated three-factor model based on Rome III subgroups and a bifactor model consisting of a g…
Validation of the German version of the Bodily Distress Syndrome 25 checklist in a representative German population sample
2020
Abstract Objective The Bodily Distress Syndrome 25 (BDS 25) checklist is a self-report instrument that can be used for case finding of a BDS in both clinical practice and research. We assessed the reliability and the internal and external validity of the German version of the BDS 25 in a sample of the general German population. Methods The psychometric properties of the BDS 25 German were examined in a representative cross-sectional German population survey which included 2386 persons aged ≥14 years. Validation instruments included the Somatic Symptom Scale 8, the Giessen Subjective Complaints List 8 and the Patient Health Questionnaire 4. Participants were asked if they had been diagnosed …
Measurement invariance of the Satisfaction with Life Scale by gender, age, marital status and educational level
2019
Introduction The Satisfaction with Life Scale (SWLS) has shown strong evidence of acceptability, reliability, validity and invariance for gender, whereas there is mixed evidence of invariance by culture and age and the literature has not explored the roles of marital status and educational level. The SWLS should be invariant by marital status and educational level to be able to compare scores between groups. We aimed to explore the invariance of the SWLS by marital status and educational level. Method A convenience sample of 726 Spanish adults participated in a survey. We tested a one-factor model using confirmatory factor analysis. We tested the configural, metric and scalar invariance of …
Validation of the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Spanish women
2014
Contains fulltext : 124145.pdf (Publisher’s version ) (Closed access) The Dutch Eating Behavior Questionnaire (DEBQ) was developed to measure eating styles that may contribute to or attenuate the development of overweight. It comprises three scales that measure emotional, external and restrained eating. The main goal of this study is to evaluate the internal structure of the Spanish version of the DEBQ using updated psychometric techniques in a sample of women. A sample of 647 Spanish females answered the questionnaire. Both exploratory structural equation modeling and confirmatory factor analysis were used to evaluate the factor structure of the DEBQ. Reliabilities were estimated with Cron…
A brief form of the Perceived Social Support Questionnaire (F-SozU) was developed, validated, and standardized
2015
Abstract Objectives Development of a brief instrument (F-SozU K-6) for the measurement of perceived social support in epidemiologic contexts by shortening a well-established German questionnaire (F-SozU K-14). Study Design and Setting The development of the F-SozU K-6 consisted of two phases; phase 1: the F-SozU K-14 was presented to a general population sample representative for the Federal Republic of Germany (N = 2,007; age: 14–92 years). Six items for the short form were selected based on the maximization of coefficient alpha. Phase 2: the new short form (F-SozU K-6) was evaluated and standardized in an independent second population survey (N = 2,508, age: 14–92 years). Results The F-So…
Development and validation of the Barriers to Physical Activity and Sport Questionnaire for lesbian, gay, bisexual, transgender and queer/questioning…
2020
Abstract Objective The objective of the study was to develop the Barriers to Physical Activity and Sport Questionnaire for lesbian, gay, bisexual, transgender and queer/questioning (BPASQ-LGBTQ+ [encompassing all spectrums of sexuality and gender]) persons (BPASQ-LGBT), which measures barriers using a socio-ecological model, and to validate it through exploratory and confirmatory factor analysis. Study design Validation study. Methods First, content validity was achieved by (a) developing a bank of items, (b) discussing the adequacy of the items in a committee of experts and classifying the selected ones under three socio-ecological levels (intrapersonal, interpersonal, environmental) and (…
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…
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…
