Parents of 37 children with asthma (aged between three and five years) and of 37 healthy controls were interviewed about their involvement in everyday care, discipline practices, perceptions of their child and situations which were particularly stressful. There was little correlation between mothers' and fathers' preferences for different discipline practices. There was, however, greater agreement in their perceptions. Parents of children with asthma did not differ from those of healthy controls in discipline practices. However, children with asthma were perceived to be generally less healthy. Parents of those with asthma also reported a greater number of everyday situations to be stressful. These data do not support traditional assumptions that parents of children with asthma are more permissive or overindulgent. At least in this preschool sample, there was only limited indication of adverse effects of chronic disease on parenting practices.
