Adaptation and Validation of the Instrument for Adopting the Role of Family Caregiver for Chronic Patients

Abstract

Introduction: Disability due to stroke in older adults requires a caregiver; assuming this role entails life changes, challenges, knowledge, and skills. However, the lack of culturally adapted instruments in Mexico limits the understanding of the transition process to adopting the caregiver role. Objective: To adapt and validate the instrument for the Adoption of the Role of Family Caregiver of a Chronic Patient (ROLE) in the Mexican context. Methodology: Five-stage methodological study: Validation by judges, style correction, pilot test, psychometric properties, and factor analysis. Results: Item validity index, 0.25; validity criterion, 16 % error; content validity index, 9.32. Kendall’s W coefficients: Comprehension [84.667/p= 0.000], clarity [78.693./p= 0.000], relevance [79.893 /p= 0.000], accuracy [78.693/p= 0.000]. Final version, criterion validity using Kaiser-Meyer-Olkin analysis is 0.78. Bartlett’s sphericity [X2 = 592.3, gl = 205, p = 0.000]. Confirmatory factor analysis showed an adequate fit of the model: CFI = 0.70; TLI = 0.66; AIC= 732.3; RMSEA = 0.087 CI [0.079/0.095]). Final internal consistency of 0.79 by Cronbach’s alpha. Conclusion: The adaptation of the ROL instrument in Mexico maintains the 22 items distributed across five domains and is a valid and reliable tool for measuring the adoption of the caregiving role.
