Diseño y validación de una escala de adherencia a antineoplásicos orales / Design and validation of an adherence scale to oral antineoplastic drugs

Objetivo: diseñar y validar una escala para medir la adherencia a antineoplásicos orales. Disponer de una herramienta sencilla, validada y aplicable a la rutina asistencial que permitirá detectar e identificar la falta de adherencia para establecer estrategias que permitan mejorarla y optimizar la calidad de los servicios sanitarios.Métodoestudio de validación de una escala diseñada para evaluar la adherencia a antineoplásicos orales en una muestra de pacientes ambulatorios que recogen su medicación en 4 hospitales españoles. Se analizará su validez y fiabilidad, elaborada a partir de un estudio previo de metodología cualitativa, mediante la teoría clásica de los test y el análisis Rasch. Se examinará su funcionamiento, el ajuste de los ítems, la estructura de respuesta y de las personas a las predicciones del modelo, así como la dimensionalidad, la fiabilidad ítem-persona, la adecuación del nivel de dificultad de los ítems a la muestra, y el funcionamiento diferencial de los ítems en función del sexo.

Objective: To design and validate a questionnaire to measure adherence to oral antineoplastic drugs. The availability of a simple, validated tool that can be applied to routine care will make it possible to detect and identify non-adherence in order to establish strategies to improve adherence and optimize the quality of healthcare services.MethodValidation study of the questionnaire designed to assess adherence to antineoplastic drugs in a sample of outpatients who collect their medication in two Spanish hospitals. Its validity and reliability will be analyzed, based on a previous qualitative methodology study, using classical test theory and Rasch analysis. We will examine its performance, item fit, response structure and person fit to the predictions of the model, as well as dimensionality, item-person reliability, the appropriateness of the level of difficulty of the items to the sample, and the differential performance of the items according to gender.
