PMID 27617563WHAT IT FOUND
The Zarit Burden Interview gave consistent burden scores for family caregivers of people with heart failure.
Use the total score, not separate scores; a score of 17 or more was linked with more depressive symptoms.
Key findings
01The Zarit Burden Interview produced consistent scores in 124 analysed caregivers (Cronbach's alpha .92).
02Caregivers with a ZBI score of 17 or more had more than double the mean depressive symptom score of caregivers with lower burden, on the 0 to 27 depression scale (7.0±6.86 vs 3.11±4.35).
03The items grouped into four factors explaining 62.8% of the variance, but the authors recommend using the total score rather than factor scores.

What it does not show
Only 124 of 143 caregivers were analysed because missing data were excluded. Most caregivers were female and Caucasian, so findings may not apply to male caregivers or other ethnic groups. The study used baseline questionnaire data; it did not test whether using the ZBI improves caregiver or patient outcomes. Subscale scores were not proposed or tested, so only the total score is supported. Two items about wanting to do more or better correlated weakly with most other items and strongly with each other.

The easy way to misread this
Do not use the four factor scores as validated subscales. The study found four factors, but it did not propose or test subscale scoring, and the authors recommend using the total score only.
