Maternal criticism, mother-child interaction, and bronchial asthma.

The study investigated maternal critical attitude (CA) and negative mother-child communication in families with an asthmatic child and in controls. Twenty-five children with bronchial asthma (7-13 yr) and 25 healthy children with their mothers participated in the project. Mothers were asked to describe their child (Five Minute Speech Sample; FMSS). Additionally mother and child discussed a mutual problem (Problem Discussion; PD). Videorecordings were taken. CA was assessed from the mothers' responses during FMSS. Negative verbal behavior during PD was coded for mother and child. During FMSS significantly more mothers of the asthmatic children than of the controls showed CA. During PD mothers of the asthmatic children made significantly more critical remarks than their controls. Within the asthmatic group, CA mothers showed significantly more criticisms than those with non-CA. Significantly more long sequences of negative verbal interaction occurred in mother-child-dyads with a CA mother than in those with a non-CA mother.
