This paper reports some of the preliminary findings of an investigation of the ways in which married couples experience pregnancy. Demographic, historical, personal, and marital information was gathered through individual interviews with each prospective parent. The 57 variables measured were combined to make six clusters: (1) experience of pregnancy, (2) psychophysiologic response to pregnancy (physical well-being and anxieties), (3) marital relationship, (4) social support, (5) expectations of labor and delivery, and (6) expectation of parenting. When the father and mother interview clusters were intercorrelated, several patterns emerged regarding differences and similarities in responses. Conclusions drawn from the statistical comparisons of the data suggest that fathering is as involved and varied an experience as mothering and that pregnancy is a dyadic experience for the prospective parents.
