Propiedades psicométricas del cuestionario de percepción de justicia en la lectura de la prensa deportiva

Introducción. El presente estudio analiza las propiedades psico- métricas del cuestionario de percepción de justicia en la lectura de la pren- sa deportiva. Apoyados en la teoría organizacional del ámbito del trabajo (Greenberg, 1987) y en el cuestionario de percepción de justicia de Colquitt (2001), se adaptaron los conceptos al ámbito de la prensa deportiva, dado que no existen instrumentos que midan la inuencia de la lectura de la prensa deportiva sobre la percepción de justicia de los lectores. Método. La muestra se compuso de 220 participantes, 166 hombres y 54 mujeres, con edades de 20,72 ± 3,08 años (18-41 años). Se realizaron análisis factoriales exploratorio y conrmatorio para analizar la estructura factorial del cues- tionario con dos submuestras divididas aleatoriamente. Resultados. Los resultados mostraron la viabilidad y adecuación de una estructura con tres factores (justicia informacional, justicia interpersonal, justicia distributiva) con adecuados índices de ajuste de validez y abilidad, mostrando eviden- cias consistentes de la estructura factorial obtenida. Discusión. Disponer de un instrumento válido para medir la percepción de justicia que origina la lectura de la prensa deportiva en los lectores podrá en el futuro originar lí- neas de investigación de gran interés social y cientíco. Estas líneas podrán abrir nuevos conocimientos en la psicología del deporte que nos permitan actuar de modo más adecuado en el tratamiento de los eventos deportivos mediáticos.

Invarianza factorial del Cuestionario de Autoconcepto Físico Modificado (CAF-M) en universitarios mexicanos deportistas y no deportistas

El objetivo principal del presente estudio fue examinar la invarianza factorial del Cuestionario de Autoconcepto Físico Modicado (CAF- M) en universitarios mexicanos deportistas y no deportistas. La muestra total fue de 1.528 universitarios mexicanos, 651 deportistas y 877 no deportistas, con una edad media de 20,78 años (DE = 2,45). Los análisis factoriales conrmatorios mostraron que una estructura de dos factores es viable y adecuada para ambas poblaciones. Atendiendo a criterios estadísticos y sustantivos, la estructura de dos factores (competencia motora y atractivo físico) ha mostrado adecuados indicadores de ajuste de abilidad y validez. Además, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes en las dos poblaciones estudiadas. Se encontraron diferencias entre los universitarios deportistas y no deportistas para las medias de ambos factores. Por último, el presente estudio también conrma la validez del modelo bidimensional del autoconcepto físico. Futuras investigaciones deberían replicar estos hallazgos en poblaciones con diferentes factores culturales y personales.

A cross-sectional study on the deprivation and sex differences in health-related fitness measures in school children

This study aimed to investigate deprivation and sex differences in selected health-relatedfitness measures in 9-12-year-old children. Data were captured on 3,407 children (49.3% boys; aged 10.5 ± 0.6 years). Cardiorespiratory fitness(20 m multistage shuttle run test; 20 m MSRT), muscular strength (handgrip strength) and body mass index (BMI) were measured. Welsh Index of Multiple Deprivation (WIMD) scores were used to make quintile groups. A two-way Analysis of Variance examined differences in BMI z-score by sex and WIMD quintiles. Two-wayAnalysis of Covariances investigated the effect of sex and WIMD quintiles on grip strength and shuttles achieved in 20 m MSRT, adjusting for BMI z-score and maturation, repectively. Independent of sex, children in the middle quintile had a significantly higher mean BMI z-score (p = 0.029) than their least deprived counterparts. There was a significant increase in grip strength (p = 0.005) and20 m MSRT (boys p < 0.001; girls p = 0.028) between most and least deprived quintiles. Significant differences in 20 m MSRT score were more apparent with decreases in deprivation in boys.Overall, inequalities exist in health-related fitness by sex and deprivation. These results can be used to inform focused services to improve current and future health

Active children through individual vouchers – evaluation (ACTIVE): protocol for a mixed method randomised control trial to increase physical activity levels in teenagers

BackgroundMany teenagers are insufficiently active despite the health benefits of physical activity (PA). There is strong evidence to show that inactivity and low fitness levels increase the risk of non-communicable diseases such as coronary heart disease (CHD), type 2 diabetes and breast and colon cancers (Lee et al. Lancet 380:219–29, 2012). A major barrier facing adolescents is accessibility (e.g. cost and lack of local facilities). The ACTIVE project aims to tackle this barrier through a multi-faceted intervention, giving teenagers vouchers to spend on activities of their choice and empowering young people to improve their fitness and PA levels.DesignACTIVE is a mixed methods randomised control trial in 7 secondary schools in Swansea, South Wales. Quantitative and qualitative measures including PA (cooper run test (CRT), accelerometery over 7 days), cardiovascular (CV) measures (blood pressure, pulse wave analysis) and focus groups will be undertaken at 4 separate time points (baseline, 6 months,12 months and follow-up at 18 months). Intervention schools will receive a multi-component intervention involving 12 months of £20 vouchers to spend on physical activities of their choice, a peer mentor scheme and opportunities to attend advocacy meetings. Control schools are encouraged to continue usual practice. The primary aim is to examine the effect of the intervention in improving cardiovascular fitness.DiscussionThis paper describes the protocol for the ACTIVE randomised control trial, which aims to increase fitness, physical activity and socialisation of teenagers in Swansea, UK via a voucher scheme combined with peer mentoring. Results can contribute to the evidence base on teenage physical activity and, if effective, the intervention has the potential to inform future physical activity interventions and policy

Risk factors for developing ventilator-associated lower respiratory tract infection in patients with severe COVID-19:a multinational, multicentre study, prospective, observational study

Around one-third of patients diagnosed with COVID-19 develop a severe illness that requires admission to the Intensive Care Unit (ICU). In clinical practice, clinicians have learned that patients admitted to the ICU due to severe COVID-19 frequently develop ventilator-associated lower respiratory tract infections (VA-LRTI). This study aims to describe the clinical characteristics, the factors associated with VA-LRTI, and its impact on clinical outcomes in patients with severe COVID-19. This was a multicentre, observational cohort study conducted in ten countries in Latin America and Europe. We included patients with confirmed rtPCR for SARS-CoV-2 requiring ICU admission and endotracheal intubation. Only patients with a microbiological and clinical diagnosis of VA-LRTI were included. Multivariate Logistic regression analyses and Random Forest were conducted to determine the risk factors for VA-LRTI and its clinical impact in patients with severe COVID-19. In our study cohort of 3287 patients, VA-LRTI was diagnosed in 28.8% [948/3287]. The cumulative incidence of ventilator-associated pneumonia (VAP) was 18.6% [610/3287], followed by ventilator-associated tracheobronchitis (VAT) 10.3% [338/3287]. A total of 1252 bacteria species were isolated. The most frequently isolated pathogens were Pseudomonas aeruginosa (21.2% [266/1252]), followed by Klebsiella pneumoniae (19.1% [239/1252]) and Staphylococcus aureus (15.5% [194/1,252]). The factors independently associated with the development of VA-LRTI were prolonged stay under invasive mechanical ventilation, AKI during ICU stay, and the number of comorbidities. Regarding the clinical impact of VA-LRTI, patients with VAP had an increased risk of hospital mortality (OR [95% CI] of 1.81 [1.40-2.34]), while VAT was not associated with increased hospital mortality (OR [95% CI] of 1.34 [0.98-1.83]). VA-LRTI, often with difficult-to-treat bacteria, is frequent in patients admitted to the ICU due to severe COVID-19 and is associated with worse clinical outcomes, including higher mortality. Identifying risk factors for VA-LRTI might allow the early patient diagnosis to improve clinical outcomes. Trial registration: This is a prospective observational study; therefore, no health care interventions were applied to participants, and trial registration is not applicable
