The following key points should be considered when authoring the introductory section. Invite subject to participate. For a relative or parent do not have the document invite "you." It should say "your relative" or "your child." Insert short, general statement about study. Explain how or why the person was identified as a potential subject. Include essential elements such as university or institution name, etc. Give enough information to make an informed decision, but not so much (or so technical) that the subject becomes confused. Include typeface that is 12-point type or larger. If the population has trouble handling small print, then make accommodations.
