Background: The reliability and validity of the subjective component of the Dutch Objective Burden Inventory (DOBI) are unknown.


Objective: The validity and reliability of the subjective component of the DOBI were examined in caregivers of individuals with heart failure, using the original 38- and a 24-item version.


Methods: In an online cross-sectional investigation, confirmatory factor analysis was used to examine factorial validity. In examining convergent validity, corrected item-dimension correlations assessed item performance and associations between subjective subscale scores and the Bakas Caregiving Outcomes Scale. Cronbach's [alpha] examined internal consistency.


Results: The original 4-factor solution was retained and both the original and shorter versions of the subjective component of the DOBI supported adequate construct validity and internal consistency.


Conclusions: Both the 38- and 24-item forms of the subjective DOBI supported construct validity and reliability. Further studies examining the usefulness of both versions are needed in carers of individuals with more severe HF.
