Validation of the Self-Care Agency Rating Scale-Revised in a Colombian Sample

Abstract

Abstract

Introduction: The Revised Self-Care Agency Rating Scale is an instrument designed to assess health self-care in clinical population. However, studies on its psychometric properties in the general non-clinical Colombian population are unknown. Objective: To validate the Revised Self-Care Agency Rating Scale with a sample of 306 volunteer participants in Colombia. Method: Psychometric methodological study carried out between October and December 2021. For the analysis of the validity of the structure, factorial, exploratory and confirmatory analysis techniques were applied. In a complementary way, the content validity was evaluated through a panel of experts. Finally, as evidence of the instrument’s reliability, its internal consistency was analyzed using McDonald’s Omega coefficient. Results: The findings show that the ASA-R shows a one-dimensional structure that explains 61.99 % of the total variance. The assessment of the relevance, clarity, precision and comprehension of the items had results that had an average that ranged from an Aiken’s V between 0.79 and 0.99. The internal consistency showed a satisfactory index for the total scale (ω=0.93). Conclusions: The version of the ASA-R presented in this article has adequate metric properties and its use is recommended to measure health self-care agency in a healthy Colombian population.
