Abstract The Neuropsychiatric Inventory is a clinical instrument for assessing behavioral and psychological symptoms in dementia. It is based on an interview with the primary caregiver. A brief questionnaire form of the NPI was developed, intended for use in routine clinical practice (NPI-Q). This study evaluates the validity of the NPI-Q Dutch form. The NPI-Q was compared to other questionnaires, i.e. the Revised Memory and Behavioural Problems Checklist (RMBPC), the short form Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE-N), the 15 items Geriatric Depression Scale (GDS-15) and the Cognitive Screening Test (CST-20). A data set was used of geriatric outpatients who were referred for neuropsychological assessment (n = 29). Correlations between the NPI-Q and RMBPC Depression- and Disinhibition subscales were relatively high. No relationship was found between the NPI-Q and the RMBPC Memory related behavioral changes subscale, or between the NPI-Q and the IQCODE-N and the CST-20. Informant ratings on the NPI-Q depression-item were related with patient ratings on the GDS-15, especially when patients were relatively mildly cognitive impaired. Caregiver distress was strongly associated with NPI-Q symptom assessment. IN CONCLUSION: our preliminary results support validity of the NPI-Q Dutch form. It is a practical rating scale for assessing neuropsychiatric symptoms in dementia and associated caregiver distress.
