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.
