Behaviour and achievement disorders in children with high intelligence.

With 6% of the patients of a childpsychiatric population using treatment a high intelligence with an IQ of over 120 was the result. This is in agreement with the results by Reinhard (1981), but is below the results by Schmidt (1977) and justifies neither the association to a higher talent as risk factor nor as protective factor in view of a potential psychic illness. 341 child-neuropsychiatric patients with hyperkinetic syndrome (55%), Enuresis (28%), reactions of adaptation (5%), specific emotional disturbances in childhood (4%), Encopresis (3%), Psychalgy (3%) and tics (2%) were studied; thereby 22 highly intelligent patients were compared with average intelligent patients. With high intelligence better performances of concentration, more reflexive style of study, better school notes and more favourable motor capabilities, less pronounced signs of anxiety and neuroticism are found, but also a poorer social adaptation and less favourable effects of treatment. Concerning the poorer chances of treatment with high intelligence however the behaviour-therapeutic concentration of our therapy has to be pointed out, which might not offer an optimal chance for development.
