Abstract

Objective: To determine whether auditory hallucinations in community-dwelling people with dementia (PwD) living in the community impacted on quality of life (QoL), subjective wellbeing and life satisfaction. Design: Cross-sectional cohort study. Settings and participants: 1251 community-dwelling PwD and caregivers were included in this study. Measures: Neuropsychiatric Inventory Questionnaire completed by caregiver interview. Mean differences between the absence and presence of auditory hallucinations were compared to scores on three validated measures of living well: QoL in Alzheimer's disease scale (QoL-AD), World Health Organization-Five Well-being Index and Satisfaction with Life Scale. Analysis of covariance determined the confounding contributions of cognition via Mini-Mental State Examination, depression via Geriatric Depression Scale-10, caregiver stress via Relative Stress Scale and whether antipsychotic drugs were prescribed. Results: Auditory hallucinations were associated with lower scores for QoL (p < 0.001, η2 = 0.01), wellbeing (p < 0.001, η2 = 0.02) and life satisfaction (p < 0.001, η2 = 0.01). After controlling for background measures, which were potential confounds, the relationship between auditory hallucinations and QoL (p = 0.04, pη2 = 0.01) and wellbeing (p < 0.000, pη2 = 0.02) remained significant but there was no significant association with life satisfaction. Conclusion: Auditory hallucinations are associated with lower QoL and wellbeing in PwD living in the community. This has implications for targeted therapies in PwD with psychotic symptoms.
