Creation and Initial Validation of the Caregiver Analysis of Reported Experiences with Swallowing Disorders (CARES) Screening Tool

Purpose: Dysphagia is a debilitating condition with widespread consequences. Previous research has revealed dysphagia to be an independent predictor of caregiver burden. However, there is currently no systematic method of screening for or identifying dysphagia-related caregiver burden. The aim of this study was to develop a set of questions for a dysphagiarelated caregiver burden screening tool, the Caregiver Analysis of Reported Experiences with Swallowing Disorders (CARES), and pilot the tool to establish preliminary validity and reliability. Method: The questionnaire was developed through an iterative process by a team of clinical researchers with expertise in dysphagia, dysphagia- related and general caregiver burden, and questionnaire design. A heterogenous group of 26 family caregivers of people with dysphagia completed the CARES, along with the Eating Assessment Tool (EAT-10), the International Dysphagia Diet Standardisation Initiative Functional Diet Scale ( IDDSI-FDS), and the Zarit Burden Interview (ZBI). Information on construct validity, item fit, convergent validity, internal consistency, and reliability was determined via Rasch analysis model testing, Cronbach's alpha, and Spearman's rho calculations. Results: The final CARES questionnaire contained 26 items divided across two subscales. The majority of the questionnaire items fit the model, there was evidence of internal consistency across both subscales, and there were significant relationships between dysphagia-specific burden (CARES) and perceived swallowing impairment (EAT-10), general caregiver burden (ZBI), and diet restrictiveness (IDDSI-FDS). Conclusions: Results from the current study provide initial support for the validity and reliability of the CARES as a screening tool for dysphagia-related burden, particularly among caregivers of adults with swallowing difficulties. While continued testing is needed across larger groups of specific patient populations, it is clear that the CARES can initiate structured conversations about dysphagia-related caregiver burden by identifying potential sources of stress and/or contention. This will allow clinicians to then identify concrete methods of reducing burden and make appropriate referrals, ultimately improving patient care.
