The Zarit Burden Interview short 12-item form (ZBI-12) is a caregiver-reported burden instrument used to assess emotional, social, and role strain associated with caregiving. Higher scores indicate greater burden and can guide caregiver-support planning.
Formula: Zarit-12 total is the sum of 12 item responses (higher totals indicate greater burden).
ZBI short forms are widely validated for caregiver burden measurement in dementia and chronic-care populations.
Higher Zarit-12 totals indicate greater caregiver burden and need for targeted caregiver interventions.
Use when monitoring caregiver wellbeing in dementia and long-term-dependency care contexts.
Cutoff interpretation varies by setting and culture; combine with contextual psychosocial assessment.
For related assessments, see CSI, Pfeffer FAQ and ECog-12.
