Validation of the French Version of the Informal Caregiver Burden Assessment Questionnaire (QASCI) in Caregivers of Patients With COPD (VALQASCI)

Beyond its respiratory component, COPD, being a systemic condition, leads to significant problems in various domains for patients. Dyspnea remains their main complaint, but these patients also experience impairments in physical capacity, nutritional status, and symptoms of anxiety and depression, which can limit their daily physical activity and reduce their quality of life, even their life expectancy.

As the disease progresses, patients become increasingly dependent on care, experiencing difficulties in performing activities of daily living (ADLs), and social isolation is often observed.

In this context, caregivers (usually a spouse or child) play a crucial role in supporting patients with ADLs, providing assistance with medical care and symptom management. Their presence is essential for facilitating and improving patients' adherence to COPD management behaviors, such as treatment compliance or increasing daily physical activity. Thus, their role in the healthcare system is fundamental, both as a link to medical teams and as support for the patient.

However, assuming the caregiver role can heavily impact the caregiver's physical, psychological, and social well-being. A survey in Spain reveals that many caregivers face health issues and experience reduced social, leisure, and professional activities due to their role. Additionally, they may feel helpless, anxious, depressed, and vulnerable to fatigue, incapacity, and/or burnout while trying to cope with the demands related to COPD. Other studies highlight the professional impact of caregiver status, with absences linked to this situation or decreased work effectiveness. This situation can be even more challenging for caregivers of patients with advanced COPD, who face higher risks of exacerbations, hospitalizations, and mortality compared to less severely affected patients.

It is therefore essential that healthcare professionals and paramedical staff who work with COPD patients and their caregivers have a tool to assess the burden on informal caregivers. To date, the only existing tool seems to be the QASCI questionnaire, drafted and validated in Portuguese by Hipólito et al. However, due to the language barrier, this tool cannot be used with French-speaking populations.
