Introduction: cognitive accessibility is part of the general accessibility framework. Cognitive accessibility means that services are simple, consistent, clear, multimodal, error tolerant, and focused, with all users in mind.
Objectives: to validate a questionnaire on cognitive accessibility to be applied to health professionals.
Methods: The study is of a quantitative approach, with a non-experimental and cross-sectional design, developed between March and June 2022. The sample consisted of 130 health professionals from Argentina, selected through purposive sampling.
Results: the validation process was carried out in three stages. Internal consistency analysis (reliability) was performed using Cronbach's Alpha. The descriptive results with the 17 items showed a variance of 4.445 for each item, a total variance of 13.049, with a total Cronbach's Alpha of 0.701, indicating that the instrument presents internal consistency.
Conclusions: It was possible to verify that the scores of both Cronbach's Alpha and the factorial analysis allow us to affirm that the instrument has the necessary metric aspects to be used in future research, considering that it had a prior assessment by expert criteria. It can be assumed that this article becomes the starting point for future studies, in which it is intended to continue the line of research, which allows the analysis of cognitive accessibility in the context of health professionals.
