Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews.

Equipment Needs

While the source instrument was developed to be administered by computer, the PhenX Working Group acknowledges these questions can be administered in a non-computerized format (i.e. pencil and paper instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

Requirements

Requirement CategoryRequired
Average time of greater than 15 minutes in an unaffected individualNo

Specialized requirements for biospecimen collectionNo

Definition

This questionnaire assesses personal and family history among adults of glaucoma, macular degeneration, cataract, and diabetic retinopathy, including history of any associated laser or eye surgeries.

Purpose

Glaucoma, macular degeneration, cataract and diabetic retinopathy are the most common forms of blindness in the U.S. and throughout the world. All of these conditions have complex inheritance involving multiple genetic and/or environmental risk factors. Family history of these conditions, especially in first degree relatives, is a significant risk factor for disease.

Selection Rationale

Questions asking about family history of ocular conditions need to accurately assess the occurrence of disease in family members and also need to accurately identify the relationships between family members. This protocol was chosen because both of these requirements were met using a relatively short questionnaire.
