The ABCC-CHF tool demonstrated high validity (97% with KCCQ), excellent internal consistency (Cronbach's α 0.92), and test-retest reliability (ICC 0.97) in CHF patients.
The newly developed ABCC-CHF module is a valid and reliable tool for assessing disease burden in patients with chronic heart failure.
Objective To develop a chronic heart failure (CHF) module for the Assessment of Burden of Chronic Conditions (ABCC) tool and evaluate its psychometric properties. Design Mixed methods study. Setting The study was conducted in the Netherlands. Participants Healthcare providers (ie, general practitioners (GPs), practice nurses, cardiologists, heart failure nurse practitioners, heart failure specialist nurses) and patients with CHF were involved in the developmental phase. In the psychometric evaluation, patients with CHF were included. Results The ABCC-CHF module comprised 26 items across CHF-specific domains, accompanied by associated advice. It demonstrated high convergent validity with the Kansas City Cardiomyopathy Questionnaire (KCCQ) (97%) and successfully differentiated most known-groups. Internal consistency yielded a Cronbach’s α of 0.92 for the total scale, while test-retest reliability showed an intraclass correlation coefficient (ICC) of 0.97. Conclusion The CHF-specific module is developed and validated. It aims to integrate disease burden into routine healthcare, supporting person-centred care for people with CHF and multimorbidity.
Keijsers et al. (2026) studied this question. The ABCC-CHF tool demonstrated high validity (97% with KCCQ), excellent internal consistency (Cronbach's α 0.92), and test-retest reliability (ICC 0.97) in CHF patients.
