Interviewer instructions
The respondent should think of one of those days in which they did vigorous activity during the past 7 days and give an estimate of the total time they spent doing vigorous activities on that day. The respondent should think of only activities undertaken for at least 10 minutes duration. The maximum hours in a day is 24 and the maximum minutes in a day is 1440. The interviewer should check for any implausible responses. If the respondent says each day was very different, ask them to estimate the usual or average time spent doing vigorous activities on a day.
The actual response provided by the respondent should be recorded. For example, “120 minutes” is recorded in the minutes response space. “Two hours” should be recorded as “2” in the hours column. A response of “one and a half hours” should be recorded as either “1” in hour column and “30” in minutes column.
