Openings and closings in Spanish email conversations
2011
Abstract Despite the increasing interest scholarly research has shown in the study of computer-mediated communication, there is still a need to investigate the empirical validity of assumed homogeneity of language usage over the net and focus on the social diversity and variation that characterizes any communication. With this in mind, the present paper is an investigation into the stylistic choices that a particular group of email users made when engaged in a specific activity type. More specifically, it explores the variation in the discourse practices employed to open and close emails in conversation alongside the institutional power of participants and the interactional position of each…
Social Validity Evaluation of the Hanen Program It Takes Two to Talk® in Spain
2020
This study sought to assess the social validity of It Takes Two to Talk (ITTT)®—the Hanen Program for parents, delivered to families of children with language delays in Valencia, Spain. Social validity was assessed using a multi-method approach—questionnaires (filled out by the parents) and a focus group—at different times during the program and at follow-up. The acceptability of the procedures used in ITTT® was positive in terms of the program format and the didactic resources used, such as the video-recordings of the parent–child interactions. Parents also expressed their overall satisfaction with the results regarding changes in their communication style and the advances observed in the…
The Irritation Scale as an Instrument to Measure Stress among University Students
2013
AbstractThe objective of this study was to verify the factor validity and structure of the “Irritation Scale” in a sample of 578 Spanish university students. At the same time, the study aimed to verify the criterion-related validity of the scale, analyzing the results obtained through correlation with other variables, such as general self-efficacy, self-regulation, depression, and certain personality dimensions. The results obtained through the Exploratory Structural Equation Modeling approach (ESEM) using Mplus confirmed the presence of two factors in the Irritation Scale, as observed in other international studies within a workplace setting. The significant correlations obtained between t…
Does Identity Precede Intimacy? Testing Erikson's Theory on Romantic Development in Emerging Adults of the 21st Century
2010
Erikson stated that healthy identity development during adolescence is a precursor of intimacy in romantic relationships during emerging adulthood. However, from a developmental contextual perspective, there are reasons to question this strict developmental ordering. Using interview and questionnaire data from a longitudinal study on 93 adolescents, the authors tested whether ego development in middle adolescence predicts intimacy in emerging adulthood. Second, the authors examined whether identity achievement at the transition to adulthood mediates this link. Results revealed direct links between early ego development (age 15) and intimacy in romantic relationships (age 25). No paths were…
Factor Structure and Longitudinal Factorial Validity of the Core Self-Evaluation Scale
2018
Abstract. The personality high-order concept of core self-evaluations (CSE), which refers to a basic evaluation of one’s worth, capability, and effectiveness, has attracted a lot of research interest. Yet little is known about the construct validity of the core self-evaluation scale (CSES) while information on its longitudinal factorial validity is wholly lacking. This study investigated the factor structure of the CSES using both confirmatory and exploratory factor analysis implemented in Mplus program. In addition, the factor loading invariance over time was investigated using exploratory structural equation modeling. Longitudinal data with three follow-ups over 2 years, gathered among u…
La evaluación del perfeccionismo: utilidad de la Escala Multidimensional de Perfeccionismo en población española
2009
La Escala Multidimensional de Perfeccionismo (MPS) de Frost et al. (1990) es uno de los instrumentos con más tradición empírica y mayor influencia en el estudio del perfeccionismo. El objetivo de este trabajo es traducir y validar la MPS para su uso en población española. Para ello, 434 participantes (77% mujeres; edad media: 23,38 años), completaron la versión española de la MPS junto con cuestionarios de obsesividad, trastornos alimentarios, y preocupaciones ansiosas, para evaluar la validez convergente de la MPS. El análisis de componentes principales (varianza explicada: 56%), reveló una estructura de 4 factores en lugar de los 6 originales: Miedo a los errores, Influencias paternas, Ex…
Overrating Classifier Performance in ROC Analysis in the Absence of a Test Set: Evidence from Simulation and Italian CARATkids Validation
2019
Background The use of receiver operating characteristic curves, or “ROC analysis,” has become quite common in biomedical research to support decisions. However, sensitivity, specificity, and misclassification rates are still often estimated using the training sample, overlooking the risk of overrating the test performance. Methods A simulation study was performed to highlight the inferential implications of splitting (or not) the dataset into training and test set. The normality assumption was made for the classifier given the disease status, and the Youden's criterion considered for the detection of the optimal cutoff. Then, an ROC analysis with sample split was applied to assess the disc…

Effect of a free healthy school meal on fruit, vegetables and unhealthy snacks intake in Norwegian 10- to 12-year-old children
2020
Abstract Background Norwegian children have a lower intake of fruit, vegetables, and a higher intake of unhealthy snacks compared to dietary guidelines. Such dietary inadequacies may be detrimental for their current and future health. Schools are favorable settings to establish healthy eating practices. Still, no school meal arrangement is provided in Norway, and most children typically bring packed lunches from home. The aim of this study was to investigate whether serving a free healthy school meal for one year resulted in a higher intake of fruit and vegetables and a lower intake of unhealthy snacks in total among 10–12-year-olds in Norway. Methods The School Meal Project in Southern Nor…
