Converging Analysis of the Concept of Strategic Group in the Spanish Lighting Industry
2008
Strategic group literature does not seem to offer strong enough theoretical bases to state the very existence of strategic groups and their effects on firm’s conduct and performance. The empirical validation of the existence of strategic groups has been usually done trying to contrast their predictive validity in relation to performance, obtaining conflicting evidence. Other papers have decided to contrast the convergent validity of the strategic group concept using different definitions and measures of this construct. Our work belongs to the second type of studies. It tries to make progress in the development of a theoretical model, able to state the industry features which affect the prob…
The Development of the Brief Eating Disorder in Athletes Questionnaire
2014
MARTINSEN, M., I. HOLME, A. M. PENSGAARD, M. K. TORSTVEIT, and J. SUNDGOT-BORGEN. The Development of the Brief Eating Disorder in Athletes Questionnaire. Med. Sci. Sports Exerc., Vol. 46, No. 8, pp. 1666–1675, 2014. Purpose: The objective of this study is to design and validate a brief questionnaire able to discriminate between female elite athletes with and without an eating disorder (ED). Methods: In phase I, 221 (89.5%) adolescent athletes participated in a screening including the Eating Disorder Inventory-2 (EDI2) and questions related to ED. All athletes reporting symptoms associated with ED (n = 96, 94.1%) and a random sample without symptoms (n = 88, 86.3%) attended the ED Examinatio…
Comparative evaluation of three semi-quantitative radiographic grading techniques for knee osteoarthritis in terms of validity and reproducibility in…
2008
OBJECTIVE: The objective of this work was to compare the measurement properties of three categorical X-ray scoring methods of knee osteoarthritis (OA), both on semiflexed and extended views. METHODS: In data obtained from trials and cohorts, X-rays were graded using Kellgren and Lawrence (KL), the OA Research Society International (OARSI) joint space narrowing score, and measurement of joint space width (JSW). JSW was analyzed as a categorical variable. Construct validity was assessed through logistic regression between X-ray stages and Western Ontario and McMaster Universities OA Index. Inter-observer reliability was assessed in 50 subjects for extended views by weighted kappa. Intra-obser…
Fitness testing in tennis: Influence of anthropometric characteristics, physical performance, and functional test on serve velocity in professional p…
2021
The aims of this study were to examine the relationship between anthropometric variables, physical performance, and functional test with serve velocity regarding tennis players’ level and to design regression models that effectively predict serve velocity. A sample of sixteen male tennis players participated in this study (national level = 8, professional level = 7). Anthropometric measurements (body mass, height, body mass index and body segments) and physical test (hand strength, countermovement jump, jump on serve, and serve velocity) and functional test (medicine ball throw overhead and shot put) were performed. No differences in anthropometrics and physical test were found between nati…
Trait self-control and self-discipline : Structure, validity, and invariance across national groups
2021
The aim of the present study was to test the validity of the Brief Self-Control Scale (BSCS; Tangney, Baumeister and Boone 2004) including its dimensional structure based on competing one- and two-factor models, discriminant validity from the conceptually-related self-discipline construct, invariance across multiple samples from different national groups, and predictive validity with respect to health-related behaviors. Samples of undergraduate students (total N = 1282) from four national groups completed the brief self-control scale, the self-discipline scale from the NEO-PI-R, and self-report measures of binge drinking, exercise, and healthy eating. Confirmatory factor analytic models sup…
Dynamic Risk Assessment of Sexual Offenders: Validity and Dimensional Structure of the Stable-2007.
2018
In this study, the predictive and incremental validity of the Stable-2007 beyond the Static-99 was evaluated in an updated sample of N = 638 adult male sexual offenders followed-up for an average of M = 8.2 years. Data were collected at the Federal Evaluation Center for Violent and Sexual Offenders (FECVSO) in Austria within a prospective-longitudinal research design. Scores and risk categories of the Static-99 (AUC = .721; p < .001) and of the Stable-2007 (AUC = .623, p = .005) were found to be significantly related to sexual recidivism. The Stable-2007 risk categories contributed incrementally to the prediction of sexual recidivism beyond the Static-99. Analyzing the dimensional struct…
Análisis de la relación entre la autoeficacia interpersonal del profesorado y sus niveles de burnout
2017
Introducción. Este trabajo se centra en la evaluación y en el análisis de la capacidad predictiva de la autoeficacia interpersonal del profesorado sobre sus niveles de burnout. Se destaca la utilidad del estudio, dada la ausencia en nuestro contexto de instrumentos de evaluación sobre este constructo psicoeducativo, así como el notable impacto de la percepción de nivel de apoyo social y del mantenimiento de relaciones satisfactorias y de ayuda en el trabajo sobre el estrés docente.Método. En el estudio participan 103 profesores de distintos niveles del sistema educativo es-pañol (55 mujeres, 48 hombres, rango de edad: 24-56), a los que se aplicó una adaptación del Teacher Interpersonal Self…
Validación de una Medida de Clima de Servicio en las Organizaciones
2012
Service climate is critical for organizations pertaining to the service sector. It reflects the importance organizations attribute to service quality and efforts to please customers. Using previous work of Schneider, White, and Paul (1998) as starting point, this research validates a measure of service climate in the Spanish language. Data from two survey study projects were brought together. A total of 120 hotels, located in Spain, participated in the research. The sample consisted of 508 frontline hotel employees distributed in 152 work-units. Our results confirmed that construct and predictive validity are satisfactory, with four factors describing the facets of service climate: Global S…
Trans-Contextual Model Predicting Change in Out-of-School Physical Activity: A One-Year Longitudinal Study
2021
The aim of the current study was to test the long-term predictive validity of the trans-contextual model in accounting for variance in adolescents’ out-of-school physical activity measured by self-report and accelerometer based-devices over a one-year period. Secondary school students ( N = 265) aged 11 to 15 years completed a three-wave survey on two occasions in time, spanning a one-year interval, measuring perceived autonomy support in physical education (PE), peer and parent autonomy support in leisure-time, autonomous and controlled motivation in PE and leisure-time, attitude, subjective norms, perceived behavioural control, intention, and out-of-school physical activity both by sel…
