D. Diamond et al., SEPARATION-INDIVIDUATION AS A FAMILY TRANSACTIONAL PROCESS IN THE TRANSITION TO PARENTHOOD, Infant mental health journal, 17(1), 1996, pp. 24-42
This is a study of the impact of prebirth level of parental and marita
l individuation on the course of parent-infant and infant development
during the first postnatal year. Support was found for the first hypot
hesis, namely, that a couple's composite individuation profile, taking
into account the prebirth separation-individuation of the father and
the mother, and their marriage, would be associated with positive infa
nt development and parent-infant transactions related to separation-in
dividuation and mutuality during the first postnatal year. A second hy
pothesis, that maternal individuation would most strongly predict infa
nt and parent-infant development at 6 months, while paternal individua
tion would emerge at 1 year as a strong predictor, was not supported.
It was found instead that prebirth maternal and paternal individuation
were equally strong predictors at six months, while maternal individu
ation was the primary predictor at 12 months. Other findings on the di
rect and indirect associations between prebirth parental and marital i
ndividuation and postnatal parent-infant transactions suggest that ear
ly separation-individuation processes result from a complex configurat
ion of triadic mother-father-infant transactions.
