Läsförmågans faktorer och deras bidrag till läsning : En jämförelse mellan barn med olika nivå av läsförmåga, utifrån The Simple View of Reading

Sammanfattning: The simple view of reading is a theory in which reading is divided into decoding and linguistic comprehension. The theory has been used to explain and to subgroup reading disabilities. Research has also investigated if additional factors are of relevance to reading. In the present study, decoding was divided into the factors orthographic decoding and phonological decoding, while comprehension was divided into word comprehension and grammatical comprehension. The purpose was to analyze these factors and their contribution to reading ability in children in fourth grade: one group with reading difficulties (n=36) and one group with typical reading ability (n=36). Results were analyzed using multiple regression and the two groups were compared. The contribution of non-verbal ability and general processing speed was also studied. The results showed differences between the groups. Decoding made the largest contribution to reading ability for the children with reading difficulties, while linguistic comprehension contributed the most for the children with typical reading ability. Differences were also found in how much the underlying factors contributed to decoding and linguistic comprehension, respectively. Non-verbal ability and general processing speed made small contributions, for both groups, to reading ability, decoding and linguistic comprehension, respectively. However, the two factors increased the explained variance in reading ability for the children with reading difficulties. In this group the two factors in The simple view of reading explained somewhat less of the variance in reading ability than for the children with typical reading ability. The study shows that decoding and comprehension are useful predictors of reading ability, and also indicates that The simple view of reading is less appropriate for children with reading difficulties.
