Abstract
A prospective, observational multicenter study was carried out assessing neuropsychiatric symptoms in a sample of 117 subjects in order to validate the Spanish version of the Problem Behaviors Assessment-Short (PBA-s). The psychometric properties of this version were analyzed. Inter- and intra-rater reliability were good: the mean weighted Cohen's kappa was 0.90 for severity scores and 0.93 for frequency scores. Four factors accounting for 56% of the total variance were identified after an exploratory factor analysis: apathy, irritability, depression, and perseveration. The PBA-s correlates strongly with the Neuropsychiatric Inventory, demonstrating its accuracy for assessing neuropsychiatric symptoms in patients with Huntington's disease.
