Background: The main aim of this study was to determine the association between Behavioral and Psychological Symptoms of Dementia (BPSD) and caregiver burden, and the mediating role of coping strategy and personality style of caregivers to patients with dementia (PWD).
Methods: This cross-sectional study was conducted among 202 caregivers to PWD in home-based settings. Recruited caregivers were administered questionnaires regarding BPSD which was measured using Neuropsychiatric Inventory-Questionnaire (NPI-Q), caregiver burden using Zarit Burden Interview (ZBI), Brief COPE for coping strategies and Big-Five Inventory which measured personality traits.
Results: Majority of the caregivers were female (71.3%), aged 50 and above (55%), single (46%), married (43.6%), working full time (45%) while the rest work part time (22.3%), unemployed (7.4%) and retiree (25.2%), and majority were parents (58.9%) and spouse (18.3%). The duration of caregiving was less than a year (33.7%) while the rest are more than a year. Results demonstrated that the most frequent types of BPSD exhibited by PWD was irritability, followed by apathy and agitation. All of the types of BPSD showed to be significantly correlated to caregiver burden except for anxiety, elation and appetite. Of personality traits, only conscientiousness was found to mediate the relationship between BPSD and caregiver burden (p < .05). Self-distraction, active coping, planning and acceptance were the coping strategies that demonstrated to have mediation effect on the relationship between BPSD and caregiver burden.
Conclusion: Presentation of BPSD is correlated to caregiver burden which is partially mediated by coping strategies and personality styles.
