Abstract

Background and Purpose: The purpose of this study was to expand on the limited psychometric testing of the NPI-Q, and extend testing to include hospitalized older adults. Method: This was a descriptive study using data from 318 dyads in an ongoing cluster randomized clinical trial. Rasch analysis and hypothesis testing were done. Results: The majority of the participants were female (62%), non-Hispanic (98%), and black (50%) with a mean age of 81.62 (SD = 8.43). There was evidence of internal consistency and invariance across race and gender. The items fit with each subscale. Hypothesis testing was supported with a significant association between the NPI-Q and dementia and caregiver distress. Conclusions: The NPI-Q is short, easy to complete, and reliable and valid when used with hospitalized older adults.
