This study aimed to enhance our knowledge of the constituent variables affecting invented writing skills in 5-year-olds by investigating the concurrent relationships among home literacy, underlying language skills, and invented writing. The study comprised 111 Norwegian-speaking children (mean age: 5.7 years; 58 girls) and their parents. The children's language skills were tested individually. The results showed that, on average, children achieved low scores on tests of word writing; however, the within-group variations in the children's invented writing performances were large. The statistical modeling showed that parental education was significantly related to the home literacy environment, which was, in turn, directly related to both vocabulary and phonological awareness and indirectly related to invented writing skills. Implications of the findings are discussed.
