The present study investigates the role of attitudinal variables, such as children's literacy interest and parents' reading beliefs, in conjunction with home literacy activities (HLA), in predicting children's print-concept knowledge. The objective of the study is to test a theoretical model describing the relationship among these variables. This study involved 551 low-income preschool children. Structural equation modelling was used to test the model. The model was a good fit for the data when parental teaching of reading/writing was used as the measure of HLA. In the model, negative parent reading beliefs and parent teaching predicted print-concept knowledge. Results suggest that practitioners should consider not only the literacy activities children and parents participate in, but also their attitudes towards those activities.
