Abstract
BACKGROUND: A proper measurement instrument is selected based on the suggested use of
the instrument, the target concept of measurement, and features of measurement (e.g. internal
consistency, reproducibility, content and construct validity, responsiveness, and interpretability).
Concerning the design and features of measurement, there are not any adequately specific standards
for instrumentation to measure oral health literacy (OHL). The present study proposes a protocol
that attempts to fill this gap by introducing the psychometrics of a standard questionnaire which
measures OHL.
MATERIALS AND METHODS: The present research employs a methodological design and is carried
out in Tehran, with data collected through interviews that are held face to face. The data collection
procedure involves a review of the related literature, cognitive interviews, fuzzy Delphi Method, and
focal groups with participants with OHL work experience for item generation. The target participants
of this research are the Iranian adult population and experts working professionally in different
health domains. For qualitative data analysis, the content analysis strategy and in the instrument
Psychometrics COSMIN checklist will use.
CONCLUSIONS: Achievement of the present research  will be used to evaluate the capability of
the Iranian adult population in searching, processing, and deciding on healthcare services. This
instrument will focus on evaluating both clinical and nonclinical settings. The present research can
vastly improve our knowledge of the state of OHL in the Iranian adult population.
