The photographic atlas of Spanish food consistency: a new tool for the treatment of dysphagia.

Introduction: dysphagia requires texture-modified foods and thickened liquids, which is difficult to explain to patients and caregivers.

Methods: an atlas has been developed and validated to explain the consistencies using the Likert scale questionnaire and the Delphi survey. The agreement and reliability of the tool were evaluated, with a minimum of 80%.
