Cross-cultural adaptation of the Innsbruck health dimensions questionnaire for neurosurgical patients (IHD-NS)

The goal of this study was to accomplish the cross-cultural adaptation of a quality of life instrument, specific for neurosurgical patients, called Innsbruck Health Dimensions Questionnaire for Neurosurgical Patients (IHD-NS). Thirty patients participated in this study, male and female, all having been submitted to brain tumor surgery more than twelve months before, and whose ages ranged from 26 to 66. After the process of translation/back translation and the elaboration of the Brazilian version of the instrument, the patients were assessed and reassessed within a one-month period. Statistical analyses evinced the preservation of the internal consistency, high agreement levels and highly significant intra-class correlation, allowing for the belief in the quality and reliability of the Portuguese version, named Questionário de Dimensões de Saúde para Pacientes Neurocirúrgicos de Innsbruck - DSI (NC).
