Translation, Adaptation, and Validation of the Preparedness Assessment Instrument for the Transition Home

Abstract

Introduction: Stroke is a leading cause of disability, affecting both survivors and their caregivers. Using a validated instrument to assess caregiver readiness for transitioning to home care will enable an optimal response to caregiving needs. Objective: The objective is to translate, adapt and validate the psychometric properties of the Preparedness Assessment for the Transition Home Instrument for its use in Mexico. Methodology: This is a methodological study with seven stages: Translation, semantic adaptation, validation by judges, style correction, pilot test, psychometric properties and factor analysis. Results: Item Validity Index: 0.37; Criterion Validity: 24% error; Content Validity Index: 10. Kendall's W: coherence (141.848/p=0.000), clarity (143.312/p=0.000), relevance (159.631/p=0.000), sufficiency (59.885/p=0.000). The final version's criterion validity, as determined by the Kaiser-Meyer-Olkin analysis, is 0.832. Bartlett's Sphericity Test yielded a chi-squared value of 2158.306, with 300 degrees of freedom and a p-value of less than 0.000. Exploratory Factor Analysis identified seven factors explaining 63.38% of the total variance. Confirmatory Factor Analysis showed an adequate model fit (X² = 779.423, df = 269, p < 0.000; CFI = 0.741; TLI = 0.687; NFI = 0.660; AIC = 941.423; PNFI = 0.547; RMSEA = 0.087, CI [0.080, 0.094]). The final internal consistency is 0.86 by Cronbach's alpha. Conclusions: The Mexican version of the instrument retains the original 25 items, which are distributed across seven domains. It is valid and reliable for the intended population.
