Specific treatment modalities, such as dyadic psychotherapies, have emerged
, based on the notion that in cases of very early relational disorders, the

ult of a complex interplay between the infant's biological risk factors and
the parents' psychological risk factors. The emphasis is on the technique
and the course of the dyadic psychotherapy of the mother and her three-year
-old child, where the main goal was to change some of the intrapsychic and
interpersonal processes specifically related to pathological motherhood. Th
e theoretical background is briefly presented, while emphasizing the criter
ia fur choosing one approach among the different kinds of dyadic psychother
apy.
