Background: Children with language impairment (LI) often have lags in development of print knowledge, an important early-literacy skill. This study explores impacts of a print-focused intervention for Spanish-speaking children with LI in Southeastern Mexico. Aims: Aims were twofold. First, we sought to describe the print knowledge (print-concept knowledge, alphabet knowledge) of Spanish-speaking children with LI. Second, we determined the extent to which print-referencing intervention delivered by children's parents could improve print knowledge. Methods & Procedures: Using a pre-test–post-test delayed treatment research design, 13 parent–child dyads were assigned to an intervention (n = 8) versus control (n = 5) condition. Children were drawn from a speech–language clinic and all were receiving services for LI. Caregivers in the intervention group implemented an 8-week home-reading programme following a systematic scope and sequence for improving children's print knowledge. Outcomes & Results: Children showed individual differences in their print knowledge based on three baseline measures examining print-concept knowledge, alphabet knowledge and letter-sound knowledge. Those whose caregivers implemented the 8-week programme showed statistically and practically significant gains on two of the three measures over the intervention period. Conclusions & Implications: The results presented here may stimulate future research on the print knowledge of Spanish-speaking children with LI. Sources of individual differences are important to determine. Caregivers may use the intervention presented here as a potential avenue for improving children's print knowledge.
