The QRCA Forum had an interesting thread about optimal days of the week for holding a bulletin board focus group. Apparently, a researcher was having difficulty conducting the online qualitative research on Friday. The consensus opinion was that optimal days were generally mid-week, Tuesday – Thursday. Other days can be productive but often require even more engagement by the moderator and prep by the recruiters.
Friday is a problem for a longitudinal project
because it is such a transition day. People’s schedules on Friday are
the most transient. They might leave early from work, go out to dinner,
catch a movie or leave town for the weekend. Even if none of that
applies, they are likely thinking about getting a bit of rest before
hitting the ground running again on Monday. It’s a very difficult day to
start something when you expect consistency.
If the online qualitative research must go over a weekend for three days (and it can work very well), it is better to start on Saturday and end on Monday. Saturday
mornings are the one time in the week that people can most control. By
the time day three rolls around (Monday), they are having fun and you have
them hooked. They are usually willing to participate one more day to
wrap up and get their incentive.
