Translation and primarily validation of the Persian Version of Caregiver Burden Inventory

Objective (s): To translate and validate the Caregiver Burden Inventory: (CBI) in Iran. The questionnaire was translated from English into Persian and face and content validity were determined qualitatively. Quantitative validation was performed using construct validity (known groups comparison and criterion validity). The Beck depression inventory and Beck anxiety inventory were used for criterion validity. Reliability was assessed by estimating internal consistency and test-retest analyses. In all 150 Alzheimer patients’ caregivers completed the Persian version of the CBI. The results obtained from known groups comparison showed that the pressure burden care of caregivers with moderate health level was significantly lower than other caregivers (p = 0.0001). Criterion validity showed a significant correlation between Persian version of CBI with Beck depression inventory (r =0.508) and Beck anxiety inventory (r = 0.686). The internal consistency (Cronbach’s alpha) was 0.930. Test-retest reliability (ICC) of the questionnaire with interval time of two weeks was 0.960. The findings indicated that the Persian version of Caregiver Burden Inventory (CBI) is a valid instrument and now could be used for measuring caregivers’ burden in research and clinical practice.
