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 α 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.
Background: Engaging families in postsurgical care is potentially beneficial for improving cancer patient outcomes and quality of care. The authors developed a family involvement program (FIP) and in this study, the authors aim to evaluate the impact of the FIP on family caregiver burden and well-being. Moreover, the authors aim to assess the fidelity of the program. Materials and methods: This is a preplanned subgroup analysis of a patient-preferred prospective cohort study that included family caregivers of patients who underwent major oncological surgery for gastrointestinal tumors. Only patient-nominated family caregivers could participate in the FIP. Caregivers received structured training in fundamental caregiving tasks from healthcare professionals and then actively participated in these tasks. Caregiver burden and well-being were measured four times (at hospital admission, at hospital discharge, and at 1 and 3 months posthospital discharge) using the Caregiver Strain Index+ (CSI+) and the Care-related Quality of Life instrument (CarerQoL-7D). The fidelity of the FIP was assessed by recording completion of care activities. In addition, family caregivers were asked whether they would participate in the FIP again. Results: Most of the 152 family caregivers were female (77.6%), and their mean age was 61.3 years (SD=11.6). Median CSI+ scores ranged between -1 and 0 and remained below the cutoff point of experiencing burden. CarerQoL-7D results indicated no significant differences in family caregivers' well-being over time. Upon discharge, over 75% of the family caregivers stated that they would recommend the FIP to others. The highest compliance with all fundamental care activities was observed during postoperative days 2-4. Conclusion: The family caregivers of oncological surgical patients who participated in the FIP exhibited acceptable levels of caregiver burden and well-being. These findings suggest that the FIP is a valuable intervention to equip family caregivers with the skills to navigate the uncertain period following a patient's hospital discharge.

A burden scale is described that is conceptually specific by concentrating on an assessment of different aspects of distress of care-giving burden and conceptually sensitive by distinguishing two dimensions: the relationship of the carer and the care-receiver and the limitations in the personal life of the carer. To develop a burden scale an analysis was carried out on a database of an intervention study in which 89 informal caregivers of psychogeriatric patients were interviewed twice. A principal components analysis was carried out showing two main factors that could be interpreted as the two dimensions mentioned above. Reliability analysis showed a Cronbach's alpha of 0.84 for the total care-giving burden scale (13 items) and 0.77 for both subscales (7 and 6 items), confirmed in an independent sample. An analysis of the hierarchy of items (Mokken Scale Analysis) showed a strong and moderate hierarchy for the subscales and the total scale, respectively. Finally, an analysis of construct validity showed strong correlations of care-giving burden with depression of the carer and deviant behaviour of the patient.
