[Importance and determinants of early mother-child relations].

In a prospective longitudinal study on child development from birth to age eight 362 first-born infants and their families were investigated. The subjects were distributed across the nine cells of a two-factorial design, factor 1 representing the degree of organic, factor 2 the degree of psychosocial risk. At age 3 months mother-child interaction was videotaped and evaluated with microanalytic technique. The quality of MCI could be demonstrated to be as predictive for later cognitive development as early developmental tests. Social-emotional problems of the toddler and preschool child was predicted better by parameters of early MCI than by temperament. Disturbed interactions were associated with later cognitive retardation and enhanced behavior problems. MCI is significantly determined by neglect and rejection, which showed typical behavioral patterns. The early separation of mother and high risk newborn itself did not lead to alterations in maternal attachment. Compared with mother daughter dyads early interaction of mother and son was characterized by more reactivity and positive emotion.
