About the Validation of this Measure
Country where validated:
Canada
Content validity:
For the generation of items, different dental patient educational materials and text types were reviewed. These included pamphlets, brochures and on-line materials, preoperative and postoperative instructions for different dental procedures, labels and instructions for commonly prescribed drugs in dentistry, and patient registration and appointment forms. The materials and texts, and the activities associated with them, were drawn from various dental health related contexts and had reading levels similar to materials used for the Test of Functional Health Literacy of Adults (TOFHLA), on which the Oral Health Literacy Instrument (OHLI) was modelled.
