Summary

The main purpose of this study is to investigate if the internet-based computer-game Grapholearn (GL) is an effective tool for early and intensive intervention of the reading decoding skills in Swedish children with DLD, as compared to two control groups of children with DLD (I) playing a math computer game, and (II) attending usual schooling.

Hypothesis: Five weeks of 20 sessions of GL will improve the accuracy of word and nonword decoding skills in children with DLD from baseline to T2 and T3. The GL intervention group will perform higher number of accuratly decoded words and nonwords than the two control groups at T2, and at T3.

The second aim is to elucidate how the parents' language and reading skills, prevalence of language-related diagnoses, and socio-economic-status, and the children's self-reported self-esteem is related to their reading skills.

Hypothesis 1: Children with DLD who's parents show poor language and/or reading skills will perform lower on the word/nonword decoding tests.

Hypothesis 2: Children who show no significant improvement of word/nonword decoding skills will to a higher degree have parents with reading difficulties.

Hypothesis 3: Parents highest level of education will not be associated with the participating childrens language and reading skills.

Hypothesis 4: Results from the self-reported self-esteem will be lower than normdata from the test manual, and will not be associated with the children's language and reading skills.
