Validation of a Spanish Version of the Lille Apathy Rating Scale for Parkinson’s Disease

Introduction. To date, no rating scales for detecting apathy in Parkinson’s disease (PD) patients have been validated in Spanish. For this reason, the aim of this study was to validate a Spanish version of Lille apathy rating scale (LARS) in a cohort of PD patients from Spain. Participants and Methods. 130 PD patients and 70 healthy controls were recruited to participate in the study. Apathy was measured using the Spanish version of LARS and the neuropsychiatric inventory (NPI). Reliability (internal consistency, test-retest, and interrater reliability) and validity (construct, content, and criterion validity) were measured. Results. Interrater reliability was 0.93. Cronbach’s α for LARS was 0.81. The test-retest correlation coefficient was 0.97. The correlation between LARS and NPI scores was 0.61. The optimal cutoff point under the ROC curve was , whereas the value derived from healthy controls was . The prevalence of apathy in our population tested by LARS was 42%. Conclusions. The Spanish version of LARS is a reliable and useful tool for diagnosing apathy in PD patients. Total LARS score is influenced by the presence of depression and cognitive impairment. However, both disorders are independent identities with respect to apathy. The satisfactory reliability and validity of the scale make it an appropriate instrument for screening and diagnosing apathy in clinical practice or for research purposes.

Validation of the Spanish version of mackey childbirth satisfaction rating scale

Background: The “Mackey Childbirth Satisfaction Rating Scale” (MCSRS) is a complete non-validated scale which includes the most important factors associated with maternal satisfaction. Our primary purpose was to describe the internal structure of the scale and validate the reliability and validity of concept of its Spanish version MCSRS-E. Methods: The MCSRS was translated into Spanish, back-translated and adapted to the Spanish population. It was then administered following a pilot test with women who met the study participant requirements. The scale structure was obtained by performing an exploratory factorial analysis using a sample of 304 women. The structures obtained were tested by conducting a confirmatory factorial analysis using a sample of 159 women. To test the validity of concept, the structure factors were correlated with expectations prior to childbirth experiences. McDonald’s omegas were calculated for each model to establish the reliability of each factor. The study was carried out at four University Hospitals; Alicante, Elche, Torrevieja and Vinalopo Salud of Elche. The inclusion criteria were women aged 18–45 years old who had just delivered a singleton live baby at 38–42 weeks through vaginal delivery. Women who had difficulty speaking and understanding Spanish were excluded. Results: The process generated 5 different possible internal structures in a nested model more consistent with the theory than other internal structures of the MCSRS applied hitherto. All of them had good levels of validation and reliability. Conclusions: This nested model to explain internal structure of MCSRS-E can accommodate different clinical practice scenarios better than the other structures applied to date, and it is a flexible tool which can be used to identify the aspects that should be changed to improve maternal satisfaction and hence maternal health.

Paracetamol vs ibuprofeno para el dolor de la episiotomía en las 42 horas postparto

Objetivo: Evaluación de la eficacia analgésica para el dolor de la episiotomía entre el paracetamol y el Ibuprofeno, en las primeras 42 horas postparto. Método: Estudio cuasi-experimental (prospectivo y simple ciego) en mujeres que dieron a luz en el HOSPITAL UNIVERSITARIO CENTRAL DE ASTURIAS (OVIEDO), excluyendo alérgicas, patologías asociadas ó aquellas que el idioma impidiese un correcto entendimiento. Dos grupos: 1) Paracetamol 1 gr; 2) Ibuprofeno 600 mg. Tamaño de muestra: 110 por grupo para alcanzar mínimo de 80. Variable principal: grado de dolor según puntuación de escala (0 a 3). Otras variables: edad de paciente, semanas de gestación, peso neonatal, paridad, inicio del parto, anestesia epidural, tipo de parto, desgarro, inflamación y enrojecimiento, hematoma, hemorroides, necesidad de sondaje evacuador, aplicación de hielo y solicitud de analgesia. Tamaño final de la muestra: 88 grupo paracetamol y 97 grupo ibuprofeno. La escala de dolor se midió a las 2 horas postparto (previo al tratamiento) y, posteriormente, cada 8 hasta 42 horas. Se realizó análisis descriptivo y comparación entre grupos. Resultados: No encontramos diferencias significativas en la escala de dolor entre ambos fármacos, ni en los subgrupos analizados, salvo en el subgrupo de partos eutócicos, donde el ibuprofeno fue superior al paracetamol. En el global de la serie, el grupo de paracetamol solicitó hielo y otra medicación con mayor frecuencia que el grupo de ibuprofeno. Conclusiones: El ibuprofeno 600 mg y el paracetamol de 1 gr obtienen una respuesta similar en las primeras 42 horas postparto, si bien el ibuprofeno parece tener algunas ventajas adicionales.

A reliable and valid questionnaire was developed to measure computer vision syndrome at the workplace

Objectives: To design and validate a questionnaire to measure visual symptoms related to exposure to computers in the workplace. Study Design and Setting: Our computer vision syndrome questionnaire (CVS-Q) was based on a literature review and validated through discussion with experts and performance of a pretest, pilot test, and retest. Content validity was evaluated by occupational health, optometry, and ophthalmology experts. Rasch analysis was used in the psychometric evaluation of the questionnaire. Criterion validity was determined by calculating the sensitivity and specificity, receiver operator characteristic curve, and cutoff point. Testeretest repeatability was tested using the intraclass correlation coefficient (ICC) and concordance by Cohen’s kappa (k). Results: The CVS-Q was developed with wide consensus among experts and was well accepted by the target group. It assesses the frequency and intensity of 16 symptoms using a single rating scale (symptom severity) that fits the Rasch rating scale model well. The questionnaire has sensitivity and specificity over 70% and achieved good testeretest repeatability both for the scores obtained [ICC 5 0.802; 95% confidence interval (CI): 0.673, 0.884] and CVS classification (k 5 0.612; 95% CI: 0.384, 0.839). Conclusion: The CVS-Q has acceptable psychometric properties, making it a valid and reliable tool to control the visual health of computer workers, and can potentially be used in clinical trials and outcome research.

Diseño y validación de una escala de autoevaluación de competencias digitales para estudiantes de Pedagogía

Este trabajo presenta el proceso de validación de una Escala de Autoevaluación de competencias digitales para estudiantes de Pedagogía. La estructura del instrumento contempla cinco dimensiones: Pedagógica - Social, Ética y Legal - Técnica - Gestión Escolar y Desarrollo Profesional. El procedimiento consideró la validación de contenido, validación de constructo a través del Análisis Factorial y la determinación de fiabilidad a través del alfa de Cronbach. La escala se aplicó a una muestra de 161 estudiantes de Pedagogía de la Universidad del Bío-Bío (Chile) que habían comenzado la actividad de práctica profesional. El proceso desarrollado permitió dar validez científica al instrumento diseñado.
