FP7 The Dutch Objective Burden Inventory: Validity and Realiability in a Canadian Population of Caregivers for People with Heart Failure
Bibliographic record
Abstract
Background: Evidence suggests that caregivers of people with heart failure (HF) often experience caregiver burden and emotional distress. However, these studies measured the caregiving experience using generic tools since a disease-specific tool was not available. Recently, the Dutch Objective Burden Inventory (DOBI) was developed as a disease-specific tool measuring objective caregiver burden in a Dutch HF population. Purpose: The purpose of this study was to validate an English version of the DOBI in a Canadian population of caregivers. Methods: Using a cross-sectional design, caregivers of HF patients attending an outpatient HF clinic completed the DOBI, the Hosptial Anxiety and Depression Scale (HADS), the Caregiver Reaction Assessment (CRA) and a basic demographic and health survey. Patient demographic and clinical data from the health record were also collected. Results: Caregivers (n=47) were mainly female (72%) and spouses (72%) of the HF patients with a mean age of 63.1 (±10.4) years. Patients were older (mean age 72.7; ±10.6), 64% male and had advanced HF. Feasability for the objective portion of the DOBI was excellent with <10% missing values. The subjective component of the DOBI had many missing values and could not be used in the analyses. Seven items had minimal variability (at least 90% reponded “yes” or “no”) Significant relationships emerged between the DOBI, CRA and HADS revealing construct validity for all subscales of the DOBI. The DOBI personal care scale significantly positively correlated with the CRA schedule burden (Spearman's rho=0.362; p<0.05). The DOBI practical support scale significantly correlated with CRA schedule burden (rho=0.442; p<0.01), HADS depression (rho=0.351; p<0.05) and HADS anxiety (rho=0.365; p<0.05). The DOBI emotional support scale significantly correlated with patient gender (rho=0.328; p<0.05), caregiver gender (rho=0.438; p<0.01) and CRA family abandonment (rho=0.293; p<0.05). The DOBI Motivational support scale significantly correlated with patient gender (rho=0.458; p<0.01) and duration in HF clinic (rho=-0.309; p<0.05). Cronbach's alpha was >0.80 for all DOBI subscales.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
