Adaptation and Validation of Amsterdam Instrumental Activities of Daily Living Questionnaire Short Version for Peru

Abstract

Background: Instrumental Activities of Daily Living (IADL) are key indicators of functional decline in dementia, but culturally adapted tools for Latin America are scarce. The Amsterdam IADL Questionnaire Short Version (A‐IADL‐Q‐SV) has shown strong psychometric properties globally but has not been validated in Peru.
