Actualización del contenido conceptual del cuestionario “Low Vision Quality Of Life Questionnaire” para evaluar la calidad de vida relacionada con la visión funcional en pacientes con baja visión residentes en Colombia en el año 2025

Abstract

Introduction: Low vision is an irreversible visual condition that, according to Wilson and Cleary's model, significantly impacts quality of life by influencing the performance of activities of daily living, including physical health, emotional state, social interaction, interaction with the environment, and functionality. This condition progressively worsens, requiring specific instruments to assess its impact. Objective: To update the Low Vision Quality of Life Questionnaire (LVQOL) to assess the quality of life related to visual function in patients with low vision residing in Colombia in 2025. Methodology: Descriptive study evaluating diagnostic tests to validate the content of the updated LVQOL questionnaire in the Colombian population with low vision. The study is conducted in three phases: a zero phase of literature review; in the next phase, the base questionnaire is reviewed by experts and patients, which integrates items from the LVQOL, NEI VFQ-25, VCM1, and VA LV VFQ-48; and finally, a pilot test of the resulting version is conducted with a group of 33 people with low vision. Results: Question 5b elicits the greatest disagreement among participants in terms of the evaluation criteria related to relevance, clarity, wording, adequacy, and relevance. Question 23 obtained greater agreement among participants in the four evaluation criteria. Conclusions: The content validity for the updated Spanish version of the LVQOL scale is adequate and constitutes a solid basis for moving toward more accurate psychometric analyses in a larger sample.
