The propensity to experience the somatic sensations as disturbing and noxious has been postulated as being a pathogenic factor in hypochondriasis. This somatic amplification style may also be a non-specific characteristic of some mental disorders with physical symptomatology. The aim of the current study has been to examine the somatic amplification style in the normal population. With this purpose 457 subjects completed the following instruments: Somatosensory Amplification Scale (SAS); Private Body Consciousness scale (Body Consciousness Questionnaire); MMPI Hypochondriasis scale; State-Trait Anxiety Inventory, and Beck Depression Inventory. Our results showed a satisfactory internal consistency, content validity and concurrent validity of the SAS. Moreover, total scores greater than 21 on this scale could be considered as a reliable cut-off point to identify persons who tend to amplify their somatic sensations.
Se ha postulado que la tendencia a experimentar las sensaciones somáticas de un modo intenso y perturbador es un elemento característico de la hipocondría y forma parte de un hipotético estilo perceptivo amplificador, si bien su presencia no se restringe a esta entidad y constituye un síntoma inespecífico de otros trastornos mentales que cursan con sintomatología física. El objetivo del presente estudio ha sido examinar la presencia de dicho estilo amplificador en la población general mediante la aplicación a una muestra de 457 sujetos sanos, de la Escala de Amplificación Somatosensorial (SAS). Los sujetos cumplimentaron además la subescala de Conciencia Corporal Privada del Cuestionario de Conciencia Corporal, el Índice Witheley, la Escala de Preocupación por la Enfermedad, la escala de Hipocondría del MMPI, el Inventario de Ansiedad Estado-Rasgo, STAI, y el Inventario de Depresión de Beck. Los resultados obtenidos indican que la SAS posee niveles satisfactorios de consistencia interna, validez de contenido y validez concurrente. Además, puntuaciones superiores a 21 identifican con razonable seguridad personas amplificadoras entre la población normal.
