I just received the following offer from Dr. Pamela Jackson, Dept. of Sociology, Indiana University. She is looking for families in our neighborhood to be a part of a study.
" Letter of invitation:
  You and your family are invited to participate in a study about family, work, and health.
  We would like to interview you in-person (we come to you any time and day of the week).
  We would like to interview 4-5 of your family members (over the telephone so they can live anywhere in the United States).
  Interviews will be completely confidential. 
  For completing an interview you will receive $20 and a 120 minute phone card.
  Your family members who complete a telephone interview will receive a 120 minute phone card. "
Sounds like an interesting study plus it includes a bonus. 
Here is a web page with more info, or you can download this word document.
