Errores de interpretación de los valores p entre psicólogos profesionales españoles: un estudio exploratorio

This paper analyzes the misinterpretatons of the p-value made by Spanish practitioner psychologists given that lack of knowledge and understanding of p value might affect the professionals’ decisions and jeopardize the quality of psychological interventions. We carried out a survey on 77 practitioner psychologists from Spain (68.8% women, mean age of 41.44 years, SD = 9.42). Our findings are consistent with previous research and suggest that many participants did not know how to correctly interpret p values. More than a third of them believed that p-value indicate the clinical or practical significance of the findings. These results highlight the importance of the training in statistical concepts, research design methodology, and statistical inference tests in order to improve professional practice among practitioner psychologists.Este artículo analiza los errores de interpretación del valor p cometidos por los psicólogos profesionales españoles dado que la falta de conocimiento y comprensión del valor de p puede afectar las decisiones de los profesionales y poner en peligro la calidad de las intervenciones psicológicas. Se realizó una encuesta a 77 psicólogos profesionales españoles (68,8% mujeres, con una edad media de 41.44 años, DT = 9,42). Nuestros hallazgos son consistentes con previas investigaciones y sugieren que muchos participantes no saben cómo interpretar correctamente los valores de p. Más de un tercio de ellos creyó que el valor p indica la importancia clínica o práctica de los hallazgos. Estos resultados destacan la importancia de la formación en conceptos estadísticos, metodología de diseño de investigación y pruebas de inferencia estadística con el fin de mejorar la práctica profesional entre los psicólogos profesionales

Statistics anxiety in university students in assessment situations

[EN] Many students have feelings of state anxiety when exams, and these feelings probably affect their performance. Statistics courses have been identified as producing the most anxiety. The purpose of our study is to measure statistics anxiety throughout an academic course (pre-test and three assessments) in order to observe its change and analyze the relationship between statistics anxiety and academic achievement. The sample is composed of 30 Psychology students taking a course in research designs and statistics (26.7% men and 73.3% women) with a mean age of 20.31 years (SD = 3.76). The results show that the students begin with a high level of statistics anxiety that gradually declines as the course progresses and they study the course materials. Moreover, the final achievement in the subject maintains an inverse relationship with the level of statostics anxiety. The recommendation is to present the detailed contents of the teaching guide on the first day of the course in order to reduce students' anxiety and uncertainty when beginning a statistics course.http://ocs.editorial.upv.es/index.php/HEAD/HEAD18Frias-Navarro, D.; Monterde-I-Bort, H.; Navarro-Gonzalez, N.; Molina-Palomero, O.; Pascual-Soler, M.; Perezgonzalez, J.; Longobardi, C.

Escala Breve de Ansiedad ante la Evaluación Académica (EBAEA-3): Brief Scale of Anxiety of the Academic Evaluation (EBAEA-3)

Resumen: Los objetivos: analizar las propiedades psicométricas de una escala breve de ansiedad ante la evaluación académica y comprobar si hay diferencias entre los alumnos que cursan una materia del área de metodología o de otras áreas. La muestra está formada por 404 alumnos de Psicología (M = 21.03 años, DT = 5.45). El 56.4% reciben formación en metodología y el 43.6% en otras áreas. Los resultados señalan que los estudiantes que reciben formación en materias metodológicas informan de un mayor grado de ansiedad ante la evaluación y perciben que tienen menor autoeficacia. Las implicaciones de los hallazgos están vinculadas con la enseñanza de los contenidos de metodología y alerta a los docentes sobre la necesidad de actuar para controlar esas percepciones. Palabras clave: ansiedad en educación; ansiedad ante la evaluación; medida, fiabilidad; validez   Abstract: The objectives: to analyze the psychometric properties of a brief scale of pre-test anxiety and discover whether there are differences between students taking subjects in the area of methodology or in other areas. The sample is composed of 404 Psychology students (M = 21.03 years, SD = 5.45). Of them, 56.4% receive training in methodology and 43.6% in other areas. The results show that the students who receive training in methodological subjects report a greater degree of pre-test anxiety and perceive themselves as having less self-efficacy. The implications of the findings are linked to the teaching of the methodology contents, and they warn professors about the need to take steps to control these perceptions.  Keywords: anxiety in education, pre-test anxiety, assessment, reliability, validity

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.
