I wish you luck. I think your approach is far better than the mailed sheets of paper surveys I inevitably toss in the recycling bin that arrive 1-2 weeks after my children's appointments. Do you guys use any sort of incentive to boost responses?
Thanks! No incentives right now, as we don't want to bias the data. Response rates have been high enough though to blow other mediums away (by a factor of 5x roughly).
