Abstract

OBJECTIVE:

The objective of the study is to examine caregiver factors as predictors of BPSD-related distress and their potential mechanisms.

METHOD:

Informal caregivers of people with dementia (n = 157) recruited from 28 community mental health teams in six NHS Trusts across England completed questionnaires regarding psychosocial factors (relationship quality, competence, guilt, health-related quality of life in the caregiver and person with dementia, reactivity to behavioural and psychological symptoms in dementia [BPSD] and burden) and frequency of BPSD. Analyses of BPSD-related distress include hierarchical multiple regression, mediation, moderation and path analysis.

RESULTS:

Caregiver psychosocial factors explained 56% of the variance in BPSD-related distress. After controlling for these factors, frequency of BPSD was not a significant predictor of BPSD-related distress. Caregiver reactivity to BPSD, burden, competence and relationship quality directly influenced BPSD-related distress. Guilt influenced distress indirectly via competence, burden and reactivity to BPSD. The final model accounted for 41% of the variance in BPSD-related distress and achieved a good fit to the data (χ2  = 23.920, df = 19, p = 0.199).

CONCLUSIONS:

Caregiver psychosocial factors including sense of competence, guilt, burden and reactivity to BPSD contribute to BPSD-related distress. Tailored interventions for managing behaviour problems in family settings could focus on these factors associated with BPSD-related distress to minimise distress in families.
