Interviewer instructions
By 'the last time you had sexual intercourse' we are referring to the respondent's most recent act of sexual intercourse.
In most cases you will record the respondent's answer by using the same units of measure he used in her response. For example, if he says '3 weeks ago', circle '2' and write '03' in the boxes next to 'Weeks ago'. If he says "4 days ago," circle '1' and write '04' next to 'Days ago'. If the respondent says "last night," circle '1' and write '00' for 'Days ago'. If the respondent answers with a month, for example, if he says "it was in December," count the number of months and record months. It may be helpful to write the name of the month in the questionnaire. All responses within less than 12 months will be recorded in months, weeks or days. Record 'year ago' only if last intercourse was one or more years ago.
If 12 months or more the answer must be recorded in years.
If the response is 12 months or more, circle '4' and record the answer in years. The 'Years ago' row should be used only if the last intercourse was more than 1 year ago. There should never be a response recorded '00' 'Years Ago'. If the response is 12 months or more, go to the SB13.
While this question is a simple one, respondents who have not had sexual intercourse recently are likely to round off their answers, and it will be up to you to learn from respondents whether they last had sex more or less than a year ago. For example, a man with no regular sexual relationships may engage in sexual intercourse on an irregular basis. Perhaps the last time he had sexual intercourse was during a trip he took 10 months ago; he will be more likely to respond "about a year ago," rather than count how many months ago it was. Therefore, you will need to probe all responses of 'a year ago' with: "Do you remember which month it was?" In this way, we will be able to determine whether the respondent actually had intercourse within the last year or more than a year ago. Respondents who last had sexual intercourse, 10, 11, 12, 13, 14 or 15 months ago may all give responses of 'a year ago'; it will be up to you to clarify when it actually was. Asking the respondent "Was it more or less than a year ago" is not a very good probe for this question; it would be best to ask, "Do you remember what month it was?"
