parents who shared a last name and whose addresses could be located. Participants were

also recruited from medical offices and clinics offering obstetrical and pediatric care and

from a support group for new mothers which is available to all women who give birth at a

local hospital. A local midwifery center distributed surveys to past clientele who were

understood to meet the sample selection criteria. Couples who met the criteria and were

personally known to the researcher were also invited to participate. Lastly, potential

participants were located through a baby fair held at a synagogue and were provided with

paper copies of the survey or with a card listing the Internet survey website.

Participants

 The participants for this study included 132 couples. Within this sample, 96

couples completed the Internet-based survey and 36 couples completed the paper-based

survey. Data from individuals whose spouses did not also complete the survey were not

included for analysis.

Participants' ages, infants' ages, and length of marriage


 The participants ranged in age from 18 to 53. The average age for wives was 29.41,

with a median age of 29. The average age for husbands was 31.36, with a median age of

31. The ages of the couples' babies and the length of the couples' marriages were

calculated based on the reported wedding dates, infants' birth dates, and dates the survey

was completed. The survey completion date was recorded for those taking the Internet

survey, and was determined for those taking the paper-based survey by the date written

on their signed informed consent or by the postmark on the return envelope. The average

amount of time between one spouse's completion of the survey and the other's was 3.05

days; the time between each spouses' completion of the survey ranged from 0 to 46 days.
