Validación de la versión en español del cuestionario "Epidemiology of Prolapse and Incontinence Questionnaire-EPIQ”

Abstract

Introduction: One out of three women suffers from pelvic floor disorders. Thus, an instrument to evaluate this pathology in common clinical practice would be very useful. In this study the psychometric characteristics of the Spanish version of the US questionnaire "Epidemiology of Prolapse and Incontinence Questionnaire-EPIQ" have been evaluated, in order to test its equivalence to the original and allow for its use in Spain. Material and Methods: 60 women with pelvic floor pathology and 60 control women filled in the Spanish version of the EPIQ. The questionnaire was validated following the statistical procedure used in the validation of the original form. Results: Factibility: 113 women filled in all questionnaire items and 7 leaved some of them blank. Validity: 7 dimensions were indentified: quality of life (QoL), overactive bladder (OAB), anal incontinence (AI), micturition difficulty/pain (MD/P), functional defecation disorders (FDD), stress urinary incontinence (SUI), and pelvic organ prolapse (POP). The validity of contents was proved comparing the mean scores for each dimension in patients and control (T-student test). Positive and negative predictive values were POP=92,3% and 82,52%; SUI= 54,34% and 84,93%; OAB=60,6% and 84,52% and AI=24,32% and 92,68%. Reliability: Global Cronbach´s-alfa was 0,94 and for the different dimensions: 0,96 (QoL); 0,91 (OAB); 0,63 (AI); 0,72 (MD/P); 0,75 (FDD) y 0,61 (SUI). Discussion: The Spanish version of the EPIQ questionnaire presents adequate factibility, validity and reliability to evaluate pelvic floor pathology in clinical practice.

Prevalencia y factores asociados a incontinencia urinaria en el área de salud este de Valladolid

“…Asimismo, hay que tener en cuenta que los pacientes se muestran reacios a consultar al clínico acerca de un tema tan delicado como puede ser la incontinencia urinaria o anal. Por ello, otra forma más válida de medir la presencia y severidad de patología de suelo pélvico consistiría en la utilización de un instrumento en forma de cuestionario autocontestado, de sencillo uso y formalmente validado (15,16) . Lukacz et al, desarrollaron y validaron en Estados Unidos, el cuestionario "Epidemiology of Prolapse and Incontinence Questionnaire-EPIQ" (17) .…”

“…La versión española del cuestionario EPIQ muestra adecuadas factibilidad, validez y fiabilidad para ser utilizado en la práctica clínica como instrumento de cribado de la patología de suelo pélvico (16)(17)(18) .…”

“…En la práctica clínica si lo que se pretende es sólo saber si existe o no un determinado problema, el EPIQ puede ser suficiente. En investigación de resultados, se ha de completar con cuestionarios específicos de cada patología, que evalúen no solo la existencia o no del problema, sino que puedan utilizarse como escalas para analizar los resultados de los tratamientos aplicados (16,17) .…”
