ABSTRACT
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.

OBJECTIVE: Analysis of the relationship between treatment and improvement on language scores in children with language problems. DESIGN: Observational longitudinal study. MATERIALS AND METHODS: 123 children between 2 and 5 years of age, diagnosed as having a language problem were followed for 1 year. By means of monthly questionnaires, the form of intervention received was recorded. Language abilities were measured at baseline and after 1 year. Mixed model analysis was used to determine the relationship between improvement and language scores. RESULTS: During the year 119 parents returned the monthly questionnaires and four treatment groups were subsequently able to be categorized: language treatment (n=21, 18%), surgical hearing improvement (n=16, 13%), language treatment and surgical hearing improvement (n=42, 35%) and a three-combination group (language treatment, surgical hearing improvement and developmental guidance, n=40, 34%). For the four treatment groups there were no significant differences at baseline for the Language Comprehension Quotient (LCQ) (p=0.07) and Sentence Development Quotient (SDQ) (p=0.09). In all treatment groups the mean Sentence Development Quotient improved significantly (p=0.001). The mean Language Comprehension Quotient did not improve in the surgical hearing improvement group (p=0.42), but improved significantly in the language treatment group, in the language treatment and surgical hearing improvement group and in the three-combination group (p=0.002, 0.040, 0.001). From all included children 38 children (32%) moved from an inadequate to an adequate language score. CONCLUSION: All distinguished forms of treatment were effective. However, only for a proportion of the children this meant a clinical relevant improvement. For the improvement of language comprehension targeted language therapy seems essential, as children without this (children receiving surgical hearing impairment) did not improve their LCQ.

OBJECTIVE: Analysis of a clinical population referred for language analysis in terms of background variables and extent of language problems. DESIGN: Descriptive study. MATERIALS AND METHODS: Children referred to a speech and hearing clinic because of assumed language problems were analyzed with standardized tests for language comprehension (Dutch version of the Reynell Developmental Comprehension Scale) and language production (Schlichting test for sentence development). A language problem was defined when the language quotient score differed 1.3S.D. from the mean (quotient scores< or =80). Furthermore, potential risk factors for language problems were compiled (gender, prematurity, birth weight, family composition, familial aggregation, parental education and daycare/home care). RESULTS: Two hundred forty children, aged between 2 and 5 years of age were included in the study. A reliable language comprehension quotient (LCQ) was obtained in 204 children (85%) and a reliable sentence development quotient (SDQ) in 206 children (85%). In 35% of the children who were assumed to have language problems, adequate language development was found. The children with language problems differed from the children without language problems with regard to language problems in the family (more family aggregation). Also the former more frequently had parents with a low level of education and more often did not attend daycare. The total referred group differed from the Dutch population with regard to gender (more boys), more instances of low birth weight, more parents with middle and high educational level, more two-parent households, fewer siblings, and more frequent attendance at daycare. CONCLUSION: Parents with a low level of education more frequently have children with language problems. However, parents with a middle and high level of education are more often concerned about the language development of their child. As a consequence, the overestimation of language problems is a real issue in clinical practice. Normal variations in language development often are not considered. The analysis of compiled background variables indicates that language problems are genetically influenced (gender and family aggregation). Language input also is of importance (interactions with a language-competent parent or caregiver and peers): children with language problems less often attended daycare.
