INFORMATION

Psicothema was founded in Asturias (northern Spain) in 1989, and is published jointly by the Psychology Faculty of the University of Oviedo and the Psychological Association of the Principality of Asturias (Colegio Oficial de Psicólogos del Principado de Asturias).
We currently publish four issues per year, which accounts for some 100 articles annually. We admit work from both the basic and applied research fields, and from all areas of Psychology, all manuscripts being anonymously reviewed prior to publication.

Background: Neuropsychiatric symptoms (NPS) are a psychopathological dimension of neurodegenerative diseases, consisting of personality changes, behavioral disorders, and alterations in basic functions such as appetite or sleep, among others. The aim of this study was the construction and validation of a screening test to identify these NPS associated with neurodegenerative pathologies in preclinical and prodromal stages, based on the ISTAART criteria for Mild Behavioral Impairment (MBI). Method: The sample consisted of 206 subjects over 55 years old (117 cognitively healthy, 89 with Mild Cognitive Impairment). 69% were women, the mean age was 77 years (SD = 10.58). Results: The new scale consists of 19 items and exhibited a one-dimensional structure. Confidence was excellent (α = .94 and Ω = .97) and there was evidence of convergent validity with the MBI-C test (r = .88) and the NPI-Q (r = .82). In addition, the scale demonstrated good sensitivity (.88) and specificity (.80). Conclusions: The scale allows evaluation of NPS in DCoL. It exhibits good psychometric properties and makes a useful tool in early diagnosis of neurodegenerative pathologies.

Antecedentes: Los síntomas neuropsiquiátricos (SNP) constituyen una dimensión psicopatológica de las enfermedades neurodegenerativas conformada por cambios en la personalidad, trastornos conductuales o alteraciones en funciones básicas como, entre otras, el apetito o el sueño. El objetivo de este estudio es la construcción y validación de un test de cribado para la identificación de estos SNP asociados a patologías neurodegenerativas en etapas preclínicas y prodrómicas y basado en los criterios ISTAART para el Deterioro Conductual Leve (DCoL). Método: Se empleó una muestra de 206 sujetos mayores de 55 años (117 cognitivamente sanos y 89 con Deterioro Cognitivo Leve) siendo el 69% mujeres, con una media de edad de 77 años (DT = 10,58). Resultados: La nueva escala desarrollada consta de 19 items y muestra una estructura unidimensional. La fiabilidad fue excelente (α = .94 y Ω = .97) y se observaron evidencias de validez convergente con el test MBI-C con una correlación de .88 y la NPI-Q con .82. Además, muestra una buena sensibilidad de .88 y especificidad de .80. Conclusiones: La escala desarrollada permite evaluar los SNP en el DCoL mostrando buenas propiedades psicométricas y constituyendo una herramienta muy útil en el diagnóstico precoz de las patologías neurodegenerativas.
