A lack of perseverance, poor attention, and poorly modulated behaviour are important criteria of Attention Deficit Hyperactive Disorder (ADHD). Instructions often have to be repeated, sometimes even by different family members before a child with ADHD attends and complies. We hypothesised that a child with ADHD might cause less disagreement in families with almost no conflicts. Responses to the Mannheim Parents Interview and teacher's form of the Conners scale completed by families of 15 boys (ages 6 to 12 years), diagnosed with ADHD were compared with those of a matched, healthy control group of 15 boys. Parents completed a form assessing the family's cooperation and child-rearing practices. Having few family conflicts, i.e., almost no Verbal Disagreement may reduce Physical Punishment and Anger and Disregard and augment the Openness to another's needs and, for that reason, have protective effects on children's behaviour modulation.

Standardized assessment of a family's characteristics (conflict management, cohesion, etc.) is not used routinely, although these variables may play an important role in the course of psychological disorders in children. The present study investigated differences within the features of families of children with hyperkinetic and emotional disorders. Families of 20 boys diagnosed with Attention Deficit Hyperkinetic Disorder and 20 boys with Emotional Disorder (ages 6-12 years) by giving the Mannheim Parents Interview and the teacher's form of the Conners scale were included for evaluation and compared with a matched, healthy control group of 20 boys. Parents were asked to complete a form assessing the family's characteristics ("Familienklima-Testsystem"), including Cohesion, Expressiveness, Conflict Tendency, Individual Independence, Achievement Orientation, Intellectual-Cultural Orientation, Active-Recreational Orientation, Moral-Religious Emphasis, and Organization. Comparison of groups was made by the Kruskal-Wallis test and Mann-Whitney U test. There are significantly more conflicts in families whose children belong to the two disorder groups. Compared with a matched healthy control group, there is low Expressiveness, Independence, and Cultural and Active-Recreational Orientation in the Emotional Disorder group and a significant lack of Organization and Cohesion in the Attention Deficit Hyperkinetic Disorder group. Altogether there seems to be a significant association of Attention Deficit Hyperkinetic Disorder symptoms with the family's Cohesion and Organization. One implication is that therapists focus their efforts not only on the children with disorders but also on their families.

A lack of perseverance, poor attention, and poorly modulated behaviour are important criteria of Attention Deficit Hyperactivity Disorder (ADHD). Instructions often must be repeated, sometimes even by different family members, before a child with ADHD attends and complies. The hyperkinetic child might cause less disruption in families with high coherence. Families of 15 boys (aged 6 to 12 years) diagnosed with ADHD using the Mannheim Parent's Interview and the teacher's form of the Conners scale were compared with a matched healthy control group of 15 boys. Parents completed a form assessing the family's cooperation and childrearing practices. Intrafamilial coherence seems to have little positive association with the family's characteristics, especially for boys with Attention Deficit Hyperactivity Disorder. Low coherence among family members may reduce ADHD symptoms and may have protective effects on children with ADHD.
