Behavioural problems in young children with language problems.

Objective: Analysis of behavioural problems in young children with language problems.

Materials And Methods: From 38 children diagnosed with a language problem, the opinion of the parents about the behaviour of their child, scored by the Child Behaviour Checklist 1.5-5 was compared with the behavioural problems in the Dutch population with the Chi-square test. T-tests and Mc Nemar tests were used to compare the opinion of the fathers about the behavioural problems with the opinion of the mothers and to compare the scores on internalizing problems with scores on externalizing problems. Plots display the measurement of the mean behavioural problems of the parents against the discrepancy between the parents and of the total behavioural problems against the discrepancy between internalizing and externalizing problems. The relation between the behavioural problems, the language score and the non-verbal intelligence score was also compared and is presented in a bar chart.

Results: All children had an inadequate language production (GDS). Twenty-seven children had an adequate and 11 children had an inadequate Language Comprehension Quotient (LCQ). Twenty-eight children had an adequate and 10 children had an inadequate non-verbal IQ (SON-IQ). In the clinical population mothers report more internalizing behavioural problems than in Dutch peers. The fathers also experience differences, but these are not significant. There is agreement between the parents in how they experience problems on the internalizing, externalizing and total problem scale. And there are no significant differences between the internalizing and externalizing problem scales, between boys and girls, and in behavioural problems in children with both adequate LCQ and SON-IQ and with inadequate LCQ and/or SON-IQ.

Conclusion: Compared to their peers in the Dutch population, young children with language problems show more internalizing problems according to their mothers. The fathers also experience differences, but these are not significant. Fathers and mothers agree on the behaviour analysis of their child and there are no differences between the occurrences of internalizing or externalizing problems and between boys and girls. There is also no relation between the behavioural problems and the severity of the language problem or the level of non-verbal functioning.
