Exposure to reading and motivation to read as mediators of the relationship between socioeconomic status and reading comprehension skills in adolescents: A multi-national investigation

This study examined the hypothesis that both exposure to reading materials in the home and intrinsic motivation to read mediate the relationship between socioeconomic status and reading comprehension skills in adolescents. Data were derived from the Program for International Student Assessment 2000 dataset (PISA 2000). Six countries out of forty-three were chosen on the basis of country-level SES: two from the bottom 25th percentile (Thailand, Mexico), two at the 50th percentile (Austria, France), and two at the 75th percentile (Norway, United States). Data analysis was conducted on a total of 27,351 participants and 823 schools. Hierarchical linear modeling (HLM) analyses were conducted to examine predictors of reading comprehension skills. Follow-up analyses using logistic regression were conducted to predict group membership (i.e., poor vs. normal readers). Results support the idea that exposure to reading materials in the home mediates the relationship between SES and reading comprehension skills at the child level, regardless of the overall economic state of the country. This relationship did not hold when predicting at the school level. Intrinsic motivation to read was consistently a poor predictor.
