Parents and Children Together (PACT), lasts for six weeks. About a hundred families in Head Start centers in Chicago have participated so far, and more than four hundred will have participated by the end of the trial run. One group was asked to commit to read to their children for a certain number of minutes each week. Parents in this group received daily text messages from the researchers reminding them of their goal and of the importance of spending time reading to their children. At the end of each week, parents received messages about the amount of time they spent reading, and they received positive recognition each week either for meeting their goals or for achieving the highest level of reading among parents in this group. The other group of parents received no such incentives, feedback, or recognition for their efforts.
