[Mannheim Rating Scales for the analysis of mother-child interaction in toddlers].

As part of a prospective study on child development from birth to age 11 the Mannheim Rating Scales for the Analysis of Mother-Child Interaction in Toddlers was constructed. Ten-minute interactions of 352 mothers and their toddlers were videotaped in the laboratory and evaluated with micro- and macroanalytic techniques. The instrument consists of a combination of second-by-second codings and dimensional ratings of 5-second to 1 minute periods. Interrater reliability, assessed by having two raters analyze 16 mother-child dyads, proved satisfactory. Psychosocial risk showed different patterns from those at low risk. Interactions of mothers and daughters seemed to be more harmonious than interactions of mothers and sons.
