Diseño y validación de un instrumento para evaluar la participación de las familias en los centros educativos

ABSTRACT  The aim of this study is to design and validate an instrument to evaluate family involvement in schools. The study was conducted with a sample of 271 legal guardians of school-age students of the different Territorial Area Directions of the Autonomous Community of Madrid (parents and custodians). We set up a theoretical model consisting of four dimensions where it the reliability, the validity of content and the construct is analyzed.The overall reliability of the instrument is very satisfactory scoring 0.928 (Cronbach's alpha) and quite acceptable giving the ratio of 0.896, Learning Support of 0.855, Participation of 0.913 and Training of 0.910. The validity of the content is supported by the theoretical foundation and the validity of experts. One Confirmatory Factor Analysis (CFA) is performed by applying S.E.M. (Structural Equation Modeling) methodology for validation of the instrument constructed obtaining an appropriate adjustment (CMIN / DF = 2.066, CFI = 0.900, RMSEA = 0.063, PRATIO = 0.916).Therefore, we can say that the instrument gets the technical characteristics required to be considered a valid and reliable approach for the study of family involvement in schools and its application in research and evaluation assessment.RESUMENEl objetivo de este estudio ha sido diseñar y validar un instrumento para evaluar la participación de las familias en los centros educativos. El estudio se ha realizado con una muestra de 271 representantes legales de estudiantes en edad escolar de las distintas Direcciones de Área territorial de la Comunidad Autónoma de Madrid (CAM) (padres, madres y tutores). Se propuso un modelo teórico compuesto por cuatro dimensiones donde se analizó la fiabilidad, la validez de contenido y de constructo.La validez de contenido fue sustentada a través de la fundamentación teórica y la validez de expertos. Se realizó un Análisis Factorial Confirmatorio (AFC) mediante la aplicación de metodología S.E.M. (Structural Equation Modeling) para la validación del constructo del instrumento obteniendo un ajuste adecuado (CMIN/DF=2.066, CFI=0.900, RMSEA=0.063, PRATIO=0.916). Por todo ello, se puede afirmar que el instrumento reúne las características técnicas exigidas para ser considerado un recurso de evaluación válido y fiable para el estudio de la participación de las familias en los centros educativos y su aplicación en investigación y evaluación.ABSTRACT  The aim of this study is to design and validate an instrument to evaluate family involvement in schools.

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background: Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods: The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results: A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion: Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
