Interpretation of findings:

... dry eye syndrome was defined as either three or more dry eye symptoms regardless of severity, or at least one symptom with moderate to severe ranking.

Clin Experiment Ophthalmol. Jun;31(3):229-32.)

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*.

*There are multiple modes to administer this question (i.e., pencil and paper and computer-assisted interviews)

Equipment Needs

Either a pencil and paper or computer-assisted instrument may be used. If a computer-assisted instrument is used, computer software may be necessary to develop the instrument. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.
