q2 i? Parent narrative utterances at 42 months significantly predict PPVT scores at 54 months after controlling for parent education, prior PPVT, and word tokens. → Rowe Meredith L 2012

q2 · i? · associational · r2

Multiple regression analysis (Model 9) predicting PPVT at 54 months in a sample of 50 dyads, of whom 48 children completed the 54-month PPVT. The association is correlational and cannot show cause. "parent uses of decontextualized language at 42-months, particularly use of narrative utterances (p < 0.05)" predicted child vocabulary with all controls in the model.

"Model 9 shows that parent uses of decontextualized language at 42-months, particularly use of narrative utterances (p < 0.05) and explanations (p < 0.10) are positive predictors of child vocabulary, controlling for quantity of parent talk, parent education and children’s PPVT scores one year earlier."
