Adaptación transcultural de la escala Low Vision Quality of life

Introduction

The quality of life related to visual function is a multidimensional construct that complements the functional assessment of patients with low vision. It shows the individual's perception of the course of ocular disease and its treatment within the framework of a value system and a sociocultural context. This clinical-epidemiological outcome is recognized as objective and valuable.

Objective

To validate the content of the spanish version of the Low Vision Quality of Life (LVQOL) scale in the Colombian population.

Methodology

A content validation study was conducted, which involved translating and back-translating the scale to evaluate semantic, idiomatic, conceptual, and experiential equivalence in the resulting version. The study included the participation of 21 individuals, and a quantitative evaluation was performed using Aiken's V coefficient to analyze the scores assigned in the categories of relevance and experiential capacity.

Results

The questionnaire presentation was reorganized. The examples were expanded, and some optical aids were mentioned. Additionally, terms were changed to improve comprehension and reduce rudeness. Out of the 25 items, 11 had an Aiken V coefficient of less than 1.0.

Conclusions

The obtained version is comparable to the original questionnaire. However, the idiomatic twists specific to the local context emphasize the need for content validation to ensure correct interpretation and contribute to the updating of the scale.
