Validación de una versión reducida en español del instrumento Barriers to Physical Activity Questionnaire for People with Mobility Impairments
2018
Objetivo. Validar una versión reducida en español del instrumento Barriers to Physical Activity Questionnaire for People with Mobility Impairments (BPAQ-MI), aplicable a diferentes tipos de discapacidad. Material y métodos. El cuestionario fue aplicado a 791 universitarios con discapacidad. La estructura factorial se validó mediante un análisis factorial confirmatorio y, para valorar la validez criterial, se llevaron a cabo correlaciones de Spearman. La fiabilidad se evaluó mediante el coeficiente alfa de Cronbach. Resultados. El modelo propuesto reveló buenos índices de ajuste y una excelente consistencia interna (α=0.920). Surgieron relaciones negativas entre las barreras experimentada…
Validity and reliability of the motivation for physical activity (RM4-FM) questionnaire
2021
There is a lack of validated instruments measuring motivation for physical activity (RM4-FM) in the Finnish language. The study examined the translated RM4-FM instrument’s psychometric properties in a sample of healthy, older Finnish adults. RM4-FM was translated and linguistically validated adhering to published guidelines. 65–75-year olds (n=102), completed the RM4-FM, the physical activity acceptance questionnaire (PAAQ) and sociodemographic characteristics questionnaires electronically. The RM4-FM was readministered one month after the initial assessment. RM4-FM translated well into Finnish. Motivation dimension scores were skewed towards high internal and low external motivation. A flo…
Validación de un instrumento de evaluación del comportamiento sexual de personas con discapacidad intelectual para padres (ECS-PA)
2019
La reciente normalización de la sexualidad y de los derechos sexuales entre las personas con Discapacidad Intelectual (DI) ha hecho que se incremente el número de iniciativas dirigidas a mejorar sus conocimientos y habilidades mediante programas de educación afectivo-sexual pero dichos programas requieren instrumentos de evaluación fiables que permitan identificar sus necesidades y puedan ser sensibles al cambio tras la intervención. En dicha valoración deben confluir sus percepciones, las de los profesionales que se ocupan de ellos y las de sus padres para asegurar la veracidad de la información obtenida, pero lamentablemente carecemos de instrumentos psicométricos válidos y fiables tanto …
Validating the Spanish version of the aggression scale in adolescents

The Scale of Physical and Verbal Aggressiveness has been an instrument widely used in the scientific literature to measure physical and verbal aggressiveness, both in children and adolescents as we...
Reviving the lost spaces under urban highways and bridges: an empirical study
2019
Purpose The fast development of urban movement infrastructures has created neglected urban places in cities. This study aims to provide users’ preferences for designing lost spaces that are a by-product of elevated urban highways (UHs) and bridges to develop a conceptual model for better environmental design. Design/methodology/approach This research is conducted by a combination of both qualitative and quantitative methods. In the first phase, to explore the citizen’s environmental preferences based on the Q-sort technique and in-depth interviews, the ideas of 50 users were considered up to data saturation. The preferences of people for designs under urban bridges were extracted by conten…
Sensory and affective components of symptom perception: A psychometric approach
2018
Psychological accounts of symptom perception put forward that symptom experiences consist of sensory-perceptual and affective-motivational components. This division is also suggested by psychometric studies investigating the latent structure of symptom reporting. To corroborate the view that the general and symptom-specific factors of a bifactor model represent affective and sensory components, respectively, we performed bifactor models applying confirmatory factor analytic approaches to the Patient Health Questionnaire-15 and the Checklist for Symptoms in Daily Life completed by 1053 undergraduate students. Additionally, we explored the association of latent factors with negative affectivi…
Is Small Still Beautiful for the Strengths and Difficulties Questionnaire? Novel Findings Using Exploratory Structural Equation Modeling.
2020
Article first published online: June 17, 2018 During the present decade a large body of research has employed confirmatory factor analysis (CFA) to evaluate the factor structure of the Strengths and Difficulties Questionnaire (SDQ) across multiple languages and cultures. However, because CFA can produce strongly biased estimations when the population cross-loadings differ meaningfully from zero, it may not be the most appropriate framework to model the SDQ responses. With this in mind, the current study sought to assess the factorial structure of the SDQ using the more flexible exploratory structural equation modeling approach. Using a large-scale Spanish sample composed of 67,253 youths ag…
Dimensions of Anxiety, Age, and Gender: Assessing Dimensionality and Measurement Invariance of the State-Trait for Cognitive and Somatic Anxiety (STI…
2018
The State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA) is a widely used measure of state and trait anxiety that permits a specific assessment of cognitive and somatic anxiety. Previous research provided inconsistent findings about its factor structure in non-clinical samples (e.g., hierarchical or bi-factor structure). To date, no psychometric validation of the Italian version of the STICSA has been conducted. Our study aimed to determine the psychometric functioning of the Italian version of the STICSA, including its dimensionality, gender and age measurement equivalence, and convergent/divergent validity in a large sample of community-dwelling participants (N = 2,938; 55.9% …
Psychometric Properties of the Spanish Version of the Nonattachment Scale (NAS) and Its Relationship with Mindfulness, Decentering, and Mental Health
2016
Abstract Nonattachment is a Buddhism-rooted construct, which can be defined as the relative absence of fixation on ideas, images, or sensory objects, as well as an absence of internal pressure to get, hold, avoid, or change circumstances or experiences. The present study was aimed at exploring the psychometric properties of the Spanish version of the Nonattachment Scale (NAS) and at delimitating the relationship between the NAS and measures of mindfulness, decentering, and negative emotional symptoms. Pooling the NAS data from Spanish meditators (n = 335) and nonmeditators (n = 270), we performed an exploratory factor analysis and then estimated the fit of two competing models (one-factor m…
2017
The analysis of open-minded attitudes towards sexuality in general requires a construct based on attitudinal dimensions. Although several existing studies involve sexual attitudes, they differ substantially and standardized conceptual work is missing. Thus, the authors introduce the latent variable sexual openness to develop a construct based on self-oriented attitudes towards different sexual topics. Available survey data of female German students in a steady relationship allowed providing a first empirical test for the applicability of this construct. Five subdimensions are acknowledged central for sexual openness: sexual practices, masturbation, bisexuality, permissiveness, and pornograp…
