title: Home literacy environment of pre-school children with intellectual disabilities.
abstract: BACKGROUND
  For pre-school children, the home literacy environment (HLE) plays an important role in the development of language and literacy skills. As there is little known about the HLE of children with intellectual disabilities (ID), the aim of the present study was to investigate the HLE of children with ID in comparison with children without disabilities.
  
  
  METHODS
  Parent questionnaires concerning aspects of the HLE were used to investigate differences between 48 children with ID, 107 children without disabilities of the same chronological age and 36 children without disabilities of the same mental age (MA). Furthermore, for the children with ID, correlations were computed between aspects of the HLE and children's non-verbal intelligence, speech intelligibility, language and early literacy skills.
  
  
  CONCLUSIONS
  From the results of the multivariate analyses of variance it could be concluded that the HLE of children with ID differed from that of children in the chronological age group on almost all aspects. When compared with children in the MA group, differences in the HLE remained. However, differences mainly concerned child-initiated activities and not parent-initiated activities. Correlation analyses showed that children's activities with literacy materials were positively related with MA, productive syntax and vocabulary age, and book orientation skills. Also, children's involvement during storybook reading was related with their MA, receptive language age, productive syntax and vocabulary age, book orientation and rapid naming of pictures. The amount of literacy materials parents provided was related to a higher productive syntax age and level of book orientation of the children. Parent play activities were also positively related to children's speech intelligibility. The cognitive disabilities of the children were the main cause of the differences found in the HLE between children with ID and children without disabilities. Parents also adapt their level to the developmental level of their child, which may not always be the most stimulating for the children.
