1 = ZBI score suggests screening for clinical depression, 0 = below threshold.
Self-care deficit score
Score indicating how much caregiver's own self-care is compromised (0-100).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Personal Strain = 1, Role strain (0-4) = 1, Time demands (0-4) = 1, Social isolation (0-4) = 1 = 10 input(s) provided
  2. Calculate Zarit Burden score
    Zarit Burden score = min(48, max(0, zbiTotal))
    10 = 10
  3. Calculate Burden category
    1 = 1
  4. Calculate Burnout risk score
    Burnout risk score
    23.1 = 23.1
