A Roma founder BIN1 mutation causes a novel phenotype of centronuclear myopathy with rigid spine

2018

ObjectiveTo describe a large series of BIN1 patients, in which a novel founder mutation in the Roma population of southern Spain has been identified.MethodsPatients diagnosed with centronuclear myopathy (CNM) at 5 major reference centers for neuromuscular disease in Spain (n = 53) were screened for BIN1 mutations. Clinical, histologic, radiologic, and genetic features were analyzed.ResultsEighteen patients from 13 families carried the p.Arg234Cys variant; 16 of them were homozygous for it and 2 had compound heterozygous p.Arg234Cys/p.Arg145Cys mutations. Both BIN1 variants have only been identified in Roma, causing 100% of CNM in this ethnic group in our cohort. The haplotype analysis confi…

Translation, adaptation and psychometric validation of the preterm birth experience and satisfaction scale (P-BESS) into Spanish.

2018

Abstract Background Preterm labour and birth are two of the most important issues in perinatal care. The birth of a preterm baby is often a stressful and traumatic time for parents. Assessment of satisfaction with maternity services is crucial and questionnaires are the most common method as long as they are well-constructed. Only one, The Preterm Birth Experience and Satisfaction Scale (P-BESS), developed in United Kingdom, has been designed for this specific birth type. Objectives To translate, transculturally adapt and assess the psychometric properties of the P-BESS into Spanish. Design Cross-sectional study. Setting Maternity unit of a tertiary level hospital in Spain. Participants A t…

Protein aggregation in congenital myopathies.

2011

Protein aggregation in congenital myopathies may be encountered among different myofibrillar myopathies such as granulofilamentous myopathy, cytoplasmic body myopathy, or spheroid body myopathy, which are designated as αB crystallinopathy, desminopathy, and myotilinopathy, respectively, according to the respective mutant proteins. Caps in cap disease and reducing bodies in reducing body myopathy were disclosed to contain numerous proteins. The multitude of diverse proteins aggregating within muscle fibers suggests impaired extralysosomal degradation of proteins, a disturbance of catabolism. The lack of different proteins accruing, but the mutant ones at an early age of affected patients in …

Dynamic relations among COVID-19-related media exposure and worries during the COVID-19 pandemic

2021

Objectives: This study investigated how COVID-19-related media exposure during the COVID-19 crisis was related to same-day and next-day COVID-19-related worries. Design: A 21-day diary study was conducted between late March and late April 2020 in Germany. Main Outcome Measures: Hypotheses were tested in a sample of 561 participants (Mage = 42.79, SDage = 6.12). Every evening, participants indicated their exposure to COVID-19-related media (e.g., TV, print, online) and their COVID-19-related worries. Results: Same-day analyses showed that participants reported more COVID-19-related worries on days with higher exposure to COVID-19-related media. Dynamical structural equation models provided e…

Psychometric properties of the "Spanish Burnout Inventory" in Chilean professionals working to physical disabled people.

2011

While the most commonly employed burnout measure has been the Maslach Burnout Inventory (MBI), researchers have been troubled by some of the psychometric limitations of this instrument. The aim of this study was to analyze the psychometric properties of the “Spanish Burnout Inventory” (SBI). The psychometric properties were analysed with data from a sample of 277 Chilean professionals working to physical disabled people. The psychometric properties of the SBI were examined through the following analyses: confirmatory factor analysis, reliability Cronbach's alpha, and concurrent validity with the MBI. The hypothesized four factor model obtained an adequate data fit for the sample (X2(164) = …

Validation of a Short Form of Job Crafting Scale in a Spanish Sample

2018

AbstractApplications of job crafting are widespread in the professional practice. In an attempt to measure this phenomenon, Tims, Bakker and Derks (2012) developed a Job Crafting Scale based on the Job Demand-Resources model (JD-R) and validated it in a Dutch sample. However, its application to other cultural contexts presented some difficulties. The present work aimed to validate a shorter version of scale by Tims et al. (2012) in a Spanish sample (n = 1,647). The data were randomly split in two independent subsamples (Sample 1: Explorative; Sample 2: Confirmative). The exploratory factor analysis showed a three-factor structure. Through a confirmatory factor analysis, the four-dimensional…

Teacher Support Resources, Need Satisfaction and Well-Being.

2015

AbstractBased on Job Demands-Resources Model (JD-R), this study examines the relationships among teacher support resources, psychological need satisfaction, engagement and burnout in a sample of 282 Spanish secondary school teachers. Nine teacher psychological needs were identified based on the study of Bess and on the Self-Determination Theory (SDT). Self-report questionnaires were used to measure the constructs selected for this study and their interrelationships were examined by structural equation modeling. The results reveal a good model fit to the data (NNFI = .88; CFI = .90; GFI = .90; RMSEA = .061). The analyses indicate a positive and significant effect of latent variable Psycholog…

Country, Sex, and Parent Occupational Status: Moderators of the Continuity of Aggression from Childhood to Adulthood

2014

Using data from two American and one Finnish long-term longitudinal studies, we examined continuity of general aggression from age 8 to physical aggression in early adulthood (age 21–30) and whether continuity of aggression differed by country, sex, and parent occupational status. In all samples, childhood aggression was assessed via peer nominations and early adulthood aggression via self-reports. Multi-group structural equation models revealed significant continuity in aggression in the American samples but not in the Finnish sample. These relations did not differ by sex but did differ by parent occupational status: whereas there was no significant continuity among American children from …

Linking empowering leadership to safety participation in nuclear power plants: a structural equation model.

2012

Abstract Introduction Safety participation is of paramount importance in guaranteeing the safe running of nuclear power plants. Method The present study examined the effects of empowering leadership on safety participation. Results Based on a sample of 495 employees from two Spanish nuclear power plants, structural equation modeling showed that empowering leadership has a significant relationship with safety participation, which is mediated by collaborative team learning. In addition, the results revealed that the relationship between empowering leadership and collaborative learning is partially mediated by the promotion of dialogue and open communication. Conclusions The implications of th…
