The effects of caregiver characteristics on behavioral and psychological symptoms of dementia of patients with dementia

OBJECTIVE: To determine the association between caregiver characteristics and behavioral and psychological symptoms of dementia (BPSD) in patients with dementia (PWD) in a Taiwanese community-dwelling population. METHODS: This cross-sectional study was conducted using the data of 190 patients with Alzheimer's disease/dementia and 190 informal matched caregivers in Taiwan. BPSD were examined using the Neuropsychiatric Inventory-Questionnaire (NPI-Q). Correlation and regression analyses were used to explore associations between caregiver characteristics and the presence, severity, and distress of NPI-Q items. RESULTS: Only spouse primary caregiver was positively associated with presence of delusions in PWD. Caregiver education was positively correlated to severity of hallucinations, agitation/aggression, and apathy/indifference in PWD, while child primary caregiver was positively related to severity of disinhibition in PWD but negatively related to severity of anxiety in PWD. Spouse primary caregiver was positively related to severity of anxiety and appetite/eating in PWD while sole primary caregiver was positively related to severity of anxiety and nighttime behaviors in PWD. Caregiver education was positively correlated to distress of agitation/aggression in caregivers while child primary caregiver was positively related to distress of disinhibition in caregivers. Spouse primary caregiver was positively related to distress of anxiety and appetite/eating in caregivers while spouse caregiver was positively related to distress of nighttime behaviors in caregivers. CONCLUSIONS: Caregiver education, child and spouse primary caregiver were relevant to severity of PWD and distress of caregivers of BPSD. It is suggested that healthcare professionals provide caregivers with proper individualized interventions based on these results to enhance caring quality.Key pointsCaregiver education was positively correlated to severity of hallucinations, agitation/aggression, and apathy/indifference, and distress of agitation/aggression.Child primary caregiver was positively related to severity and distress of disinhibition but negatively related to severity of anxiety.Spouse primary caregiver was positively related to severity and distress of anxiety and appetite/eating, and distress of nighttime behaviors.
