BACKGROUND AND PURPOSE: The informal care demands of primary malignant brain tumor (PMBT) patients include unique issues associated with neurological and cognitive symptoms. Existing caregiver needs questionnaires do not include these disease-specific symptoms, which are particularly distressing. Therefore, we have developed the neuro-oncology Caregiver Needs Screen (CNS) and evaluated its psychometric properties. METHODS: The 32-item instrument was developed based on PMBT caregiver interviews (N = 109) and expert review.
