However, these differences are likely a reflection of varying degrees of program awareness. The health plan offered a generous cash incentive to enroll in the program. The program and the incentive were promoted by employers through work sites. The intervention and comparison groups were equally likely to be employed, but married women had greater chance to hear about the program and the incentive through their husbands. Companies may have promoted the program more intensely to more highly paid, married workers, and some companies promoted the program more than others.
Married status is a well known factor in birth outcomes.
Sharing information with a partner may reinforce messages and increase recall. We recommend that future surveys ask if pregnancy health information was shared with family members or other support persons. Finally, all or any part of the differences detected could be due to information giving through extra telephone contact with case managers. Also, the intervention group did not express desire for extra contact, but rather responded to a cash incentive. Therefore, the potential additional factor contributing to significant differences in recall and satisfaction is telephone contact initiated by case managers with members of the intervention group only.
