Protocol - Years Living in the U.S.
Protocol Name from Source:
National Health Interview Survey (NHIS) Family Questionnaire, 2007
The interviewer asks the respondent how long he or she has been in the United States, in years. The number of years (2 digits) is entered by the interviewer. If the respondent has been in the United States for less than 1 year, the entry is "0."
About how long have you been in the United States?
[2-digit entry] ________
If less than 1 year given as response, code the answer as "0"; enter "00-94" for 0-94 years, enter "95" for 95+ years, 97-Refused, 99-Don’t know
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.
* There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).
While the source instrument was developed to be administered by computer, the PhenX Working Group acknowledges these questions can be administered in a noncomputerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer or handheld computer to administer a computer-assisted questionnaire.

The duration (in years) of stay in the United States, asked only of immigrants.
The purpose of this measure is to provide more detailed information related to immigrants than captured by nativity or birthplace alone. Duration in the United States has been related to various health behaviors, health outcomes, and access to health care.
Vetted against several other similar measures. This measure was selected because it captures number of years rather than the year (e.g., 2001) the person came to live in the United States.
