How much time did you usually spend walking on one of those days? (in hours per day)
The respondent should think of one of those days in which they walked during the past 7 days and give an estimate of the total time they spent walking on that day. Walking must have lasted 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 walking 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.
