This longitudinal study aimed to explore the event-specific emotional expressions of persons living with dementia in long-term care during a 6-month period with repeated observations. Emotional expressions at three specific events (mealtime, personal care, and social activity) were videotaped at the beginning, month 3, and month 6. Thirty participants were enrolled, and nine observations were made for each participant. Mixed-effect models were used for statistical analysis. The type of care events, the person who provides care, and the facility type were associated with emotional expressions. Specifically, personal care, interaction with non-nursing providers, and facility type were associated with positive emotional expressions. Negative emotional expressions were related to personal care, interaction with family or volunteer, and facility type. This study provides a better understanding of event-specific emotional expressions and knowledge to support the development of emotion-oriented intervention programs to improve the psychological well-being of persons living with dementia.
