Psychometric properties of the Brief Symptom Inventory-18 in a Spanish breast cancer sample
2007
Abstract Objective The objective of this work was to study the psychometric and structural properties of the Brief Symptom Inventory-18 (BSI-18) in a sample of breast cancer patients ( N =175). Methods Confirmatory factor analyses were conducted. Two models were tested: the theoretical model with the original structure (three-dimensional), and the empirical model (a four-factor structure) obtained through exploratory factor analysis initially performed by the authors of the BSI-18. Results The eligible structure was the original proposal consisting of three dimensions: somatization, depression, and anxiety scores. These measures also showed good internal consistency. Conclusion The results …
Psychological assessment of patients with temporomandibular disorders: confirmatory analysis of the dimensional structure of the Brief Symptoms Inven…
2006
Abstract Objective This article analyzes the psychometric and structural properties of the Brief Symptoms Inventory 18 in a sample of patients with temporomandibular disorders (TMDs), given the convenience of a brief evaluation of distress in these patients. Methods Confirmatory factor analysis was carried out in a sample of 114 patients with TMDs. Two models were tested: the theoretical model with the original structure proposed—which considers three dimensions—and the empirical model obtained through the exploratory factor analysis initially carried out by Leonard R. Derogatis—which consists of the four-factor structure. Results Both models reached satisfactory indexes in confirmatory fac…
Remodelling of biological parameters during human ageing: evidence for complex regulation in longevity and in type 2 diabetes.
2013
Factor structure analyses have revealed the presence of specific biological system markers in healthy humans and diseases. However, this type of approach in very old persons and in type 2 diabetes (T2DM) is lacking. A total sample of 2,137 Italians consisted of two groups: 1,604 healthy and 533 with T2DM. Age (years) was categorized as adults (≤65), old (66-85), oldest old (>85-98) and centenarians (≥99). Specific biomarkers of routine haematological and biochemical testing were tested across each age group. Exploratory factorial analysis (EFA) by principal component method with Varimax rotation was used to identify factors including related variables. Structural equation modelling (SEM) wa…
Collaborative Policy Making and Stakeholder Engagement: A Resident–Based Perspective
2019
This study analyses residents’ perceptions and attitudes towards tourism and community engagement with tourism planning. Overall, residents think that the positive effects of tourism development outweigh the negative impacts. Despite this, they express concerns regarding the economic future of their area and that the tourism development in their area is mostly exogenously driven. Further, they do not feel involved in tourism planning but, quite surprisingly, they do not seems to be convinced that local authorities should encourage community participation in tourism decision making. Exploratory factor analysis and hierarchical and non-hierarchical cluster analysis were therefore conducted. F…
Factorial analysis and psychometric properties of the revised Valencia scale of attitudes and beliefs towards hypnosis-client version
2007
Psychometric properties and factorial structure of the Revised Valencia Scale of Attitudes and Beliefs toward Hypnosis – Client Version using a Portuguese sample are presented. Exploratory factor analysis on a Portuguese population of undergraduate college students (N = 444) yielded 8 factors: ‘Interest/Liking’, ‘Memory/Magic’, ‘Help’, ‘Control’, ‘Cooperation’, ‘Marginal’, ‘Fear’ and ‘Automaton’. The overall 8-factor structure is similar to the one found in the therapist version of the scale, and as in the therapist version, each factor of the client version showed good internal consistency and reliability. Differences among participants that had and had not experienced hypnosis previously …
Attitudes and beliefs about hypnosis: A multicultural study
2008
The aim of this study is to examine the effects of having personal experience and information about hypnosis over the beliefs and attitudes toward hypnosis, using a sample of students from Spain, United States, Portugal and Romania. The factor structure of the Revised Valencia Scale of Attitudes and Beliefs toward Hypnosis-Client Version, as well as its psychometric properties are also analyzed. An exploratory factor analysis of the scale was conducted and an 8-factor model solution similar to the one found in other versions of this scale was obtained: Help, Personal Control, Magical Solution, Interest, Collaboration, Fear, Memory/Trance and Marginal. Results also indicated that participant…
Desarrollo y evaluación psicométrica de una forma abreviada de la escala de posicionamiento ante el diagnóstico enfermero
2013
El Position on Nursing Diagnosis (PND) es una escala que utiliza la técnica del diferencial semántico para medir las actitudes hacia el concepto diagnóstico enfermero. El estudio objetivó desarrollar una forma abreviada de la versión española de esta escala, evaluar sus propiedades psicométricas y eficiencia. Se utilizó un doble enfoque empírico-teórico para obtener una forma reducida del PND, el PND-7-SV, que fuera equivalente a la original. Mediante un diseño transversal a través de encuesta, se evaluó la fiabilidad (consistencia interna y fiabilidad test-retest), validez de constructo (análisis factorial exploratorio, técnica de grupos conocidos y validez discriminante) y de criterio (va…
How students perceive the university's mission in a Spanish university: Liberal versus entrepreneurial education?
2013
AbstractThis study explores the extent to which undergraduate students perceive a dichotomy between a liberal vs. an entrepreneurial model of university. This research is important in that it compares the stated aims of university education, particularly within the Bologna Process, with students' expectations regarding liberal education and employability. A Likert-type questionnaire containing 25 statements reflecting liberal and entrepreneurial features of university education was answered by 488 students from 10 disciplines at the University of Valencia, Spain, just before the implantation of the Bologna curriculum. An exploratory factor analysis revealed that students clearly perceive th…
The Impact of Acculturation on Attitudinal Familism in a Community of Puerto Rican Americans
1998
The goal of this study was to examine the relationship between acculturation and familism in a samnple of 182 Hispanics of Puerto Rican descent. Exploratory factor analysis was used to establish the multidimensionality of each construct. Consistent with earlier studies, three dimensions of acculturation and familism were identified. Each dimension offamilism was then regressed on a set of explanatory variables that included three dimensions of acculturation. For two dimensions offamilism (familial obligations and support from relatives), acculturation was positively related to familism; for the other dimension (family as referents), the relationship was nonsignificant. In explaining varian…
Development and validation of a scale to measure caregiver skills in eating disorders
2014
Objective:- The aim of this study was to develop and validate a new questionnaire designed to measure caregiver skills that, in line with the interpersonal component of the cognitive interpersonal maintenance model (Schmidt and Treasure, J Br J Clin Psychol, 45, 343–366, 2006), may be helpful in the support of people with anorexia nervosa (AN). A further aim is to assess whether this scale is sensitive to change following skills-based caregiver interventions. Method:- The Caregiver Skills (CASK) scale was developed by a group of clinicians and caregivers. Preliminary versions of the scale devised for both caregivers and parents were given at baseline and at follow-up after two studies of ca…
