Neuropsychiatric symptom profiles of community-dwelling persons living with dementia: Factor structures revisited.

ABSTRACT:

Objectives

Most persons living with dementia (PLWD) will develop neuropsychiatric symptoms (NPS) at some point. NPS are often clustered into subsyndromes with other related symptoms, but the evidence supporting commonly used clusters is insufficient. We reexamine behavioral clusters in community-dwelling PLWD and identify associated risk factors and potential contributors.

Methods

This study used baseline data from a longitudinal behavioral intervention study of 250 community-dwelling older adults with dementia and their caregivers. Using exploratory factor analysis (principal component analysis [PCA]), the factor structure of NPS frequency scores of the Neuropsychiatric Inventory (NPI-C) was evaluated. Multiple linear regressions assessed the association of the derived beha
