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 (e.g., pencil-and-paper and computer-assisted interviews).
Equipment Needs
While the source instrument was administered over the telephone, the PhenX Working Group acknowledges that these questions can be administered in a computerized format (i.e., computer-assisted personal interview). 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 Category | Required |
|---|---|
| Major equipment | No |
| Specialized training | No |
| Specialized requirements for biospecimen collection | No |
| Average time of greater than 15 minutes in an unaffected individual | No |
Mode of Administration
Interviewer-administered questionnaire
Lifestage
Child, Adolescent
