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. The interviewer should be trained to prompt respondents further if a "don't know" response is provided.

Equipment Needs

The PhenX Working Group acknowledges these questions can be administered in a computerized or noncomputerized format (i.e., paper-and-pencil 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.

Questionnaire to obtain the marital status of the respondent’s primary caregiver (i.e. family member or another individual who takes primary responsibility for the respondent).


Marital status of the primary caregiver is associated with socioeconomic status, academic achievement, health status and outcomes, insurance coverage, and health care utilization.

Selection Rationale

These questions from the Silent Cerebral Infarct Multi-Center Clinical Trial (SIT) were vetted against similar protocols and selected as the best methodology to capture marital status of caregivers. These questions are based on similar questions from the National Health and Nutrition Examination Survey (NHANES).
