[Development and psychometric validation of a new screening questionnaire for erectile dysfunction (SQUED questionnaire)]. / Desarrollo y validación psicométrica de un nuevo cuestionario de screening para la disfunción eréctil (cuestionario SQUED).

BACKGROUND: It is necessary to have simple tools to screen erectile dysfunction (ED) in an easy, reliable and valid manner. The objective of this study was to develop and validate a short diagnostic questionnaire for erectile dysfunction [SQUED), easy to use in the primary care setting. SUBJECTS AND METHOD: The development of SQUED included: concepts identification, item generation and evaluation of contents and face validity through interviews with subjects to assess comprehension and idiomatic adequacy. The psychometric validation was conducted in an epidemiologic, observational, comparative and multicenter study. Participants should complete the questionnaire in primary care setting and send to the specialist to confirm the diagnosis by an in depth interview and the application of IIEF questionnaire. Internal consistency, test-retest reliability and sensitivity and specificity of SQUED was evaluated. RESULTS: Out of 405 subjects enrolled, 316 (208 ED and 108 non-ED) were evaluable. The SQUED questionnaire showed a high internal consistency (Cronbach's alpha = 0.92) and a good test-retest reliability (Kappa index = 0.77). Furthermore, the questionnaire showed a good diagnostic capacity with high values of sensitivity and specificity, 0.87 and 0.78, respectively, in relation to the diagnosis made by urologists. The cutting point was established at a score of 12. DISCUSSION: The SQUED questionnaire is a simple, easy to use and reliable instrument. It can become a useful tool, and the shortest validated, for primary care physicians to easily screen for ED patients. Its simplicity should facilitate an easy cultural adaptation and validation into other languages.

[Psychological impact of erectile dysfunction on self-esteem and self-confidence]. / Repercusiones psicológicas de la disfunción eréctil sobre la autoestima y autoconfianza.

BACKGROUND AND OBJECTIVE: Erectile dysfunction (ED) is caused by a large range of organic, psychological, psychiatric, interpersonal and pharmacological factors. Numerous scientific publications mention the loss of self-esteem as a collateral effect of ED, with a very probable affectation of the subject's self-confidence. The objective of this study was to evaluate the self-esteem and self-confidence of subjects with ED and to compare them with a group of non-ED subjects. SUBJECTS AND METHOD: An epidemiological, cross-sectional, observational, comparative and multicentric study was conducted. General Practitioners selected 405 men older than 18 years in which they suspected ED. All the participants had to complete the self administered form of the Spanish version of the Rosenberg self-esteem scale and the Spanish culturally adapted version of the Johnson and McCoy self-confidence scale. After that, patients were referred to the urologist in order to confirm the ED diagnosis. RESULTS: The statistical analysis of the data showed that the subjects with ED obtained significantly lower scores in the self-confidence and self-esteem scales than the non-ED subjects (p < 0.01). DISCUSSION: The results of this study show the loss of self-confidence and self-esteem that suffer patients with ED.

Desarrollo y validación psicométrica de un nuevo cuestionario de screening para la disfunción eréctil (Cuestionario SQUED) / Development and psychometric validation of a new screening questionnaire for erectile dysfunction (squed questionnaire)

Introducción. Es necesario contar con herramientas sencillas que permitan detectar de forma válida y fiable la presencia de disfunción eréctil (DE). El objetivo de este estudio fue desarrollar y validar un cuestionario de cribado de la DE que fuera útil para usar en atención primaria (AP). Material y Métodos. El desarrollo del cuestionario SQUED (Short Questionnaire for Erectile Dysfunction) incluyó la identificación de conceptos y generación de ítems, evaluación del contenido y la validez aparente a partir de entrevistas con sujetos para valorar la compresión y adecuación del lenguaje. Para la validación psicométrica se realizó un estudio epidemiológico, observacional, comparativo y multicéntrico. Los participantes completaron el cuestionario en el ámbito de la AP y fueron derivados al especialista para la confirmación diagnóstica mediante entrevista clínica y la administración del International Index of Erectile Function (IIEF). Se evaluó la consistencia interna, la fiabilidad del test-retest y la sensibilidad y la especificidad del SQUED. Resultados. Participaron 405 sujetos, de los cuales 316 (208 con DE y 108 sin DE) fueron evaluables. El cuestionario SQUED mostró una alta consistencia interna (alfa de Cronbach = 0,92) y una buena fiabilidad test-retest (índice Kappa= 0,77). Además, el cuestionario mostró una alta capacidad diagnóstica con valores de sensibilidad y especificidad, 0,87 y 0,78, respectivamente, respecto al diagnóstico del urólogo. El punto de corte se estableció en una puntuación de 12. Discusión. El cuestionario SQUED es un instrumento sencillo, fácil de usar y fiable. Constituye una herramienta útil, y la más corta validada, para que los médicos de AP puedan identificar fácilmente pacientes con DE. Su sencillez debería hacer fácil el proceso de adaptación cultural y validación en otros idiomas

Repercusiones psicológicas de la disfunción eréctil sobre la autoestima y autoconfianza / Psychological impact of erectile dysfunction on self-esteem and self-continence

Introducción: La disfunción eréctil (DE) está causada por una amplia gama de factores orgánicos, psicológicos, psiquiátricos, interpersonales y farmacológicos. En numerosas publicaciones se menciona la pérdida de autoestima como un efecto colateral de la DE siendo muy probable también una afectación de la autoconfianza del sujeto. El objetivo del siguiente estudio fue evaluar la autoestima y autoconfianza de sujetos con DE y compararla con un grupo de sujetos sin DE. Material y Métodos: Estudio epidemiológico, transversal, observacional, comparativo y multicéntrico. Se seleccionaron 405 sujetos varones mayores de 18 años en los que el médico de Atención Primaria sospechara que pudieran padecer DE. Todos los participantes debían cumplimentar de forma autoaplicada la versión española del cuestionario de autoestima de Rosenberg y la adaptación cultural al español del Cuestionario de autoconfianza de Johnson y McCoy. Después fueron remitidos a un urólogo que confirmaba el diagnóstico de DE (“gold Standard”).Resultados: El análisis estadístico mostró que los sujetos afectados de DE obtenían puntuaciones significativamente inferiores en las escalas de autoconfianza y autoestima que los sujetos sin DE (p< 0.01).Discusión: Los resultados ponen de manifiesto la pérdida de autoconfianza y autoestima que sufren los pacientes afectados de DE (AU)
