The purpose of this study was to examine the reliability and validity of the Spanish (Spain) version of the Neuropsychiatric Inventory. The Neuropsychiatric Inventory was administered to the caregivers of 63 subjects from the Dementia Unit, Hospital Santa Caterina, Girona. All patients had detailed neuropsychological assessment, and their non-cognitive symptoms were also examined with the CAMDEX. There was a high level of internal consistency reliability. The Neuropsychiatric Inventory subscores correlated with those of the CAMDEX, indicating an acceptable level of validity. The most frequent symptom was apathy (56%), followed by irritability (38%), depression/dysphoria (35%), aberrant motor behavior (30%), agitation/aggression (29%), anxiety (27%), disinhibition (24%), delusions (19%), hallucinations (14%) and euphoria (3%). This study showed that the Spanish version of the Neuropsychiatric Inventory is a reliable instrument, which can briefly assess non-cognitive symptoms in demented patients. The Neuropsychiatric Inventory is a useful instrument for research and clinical practice in different culture around the world.
