title: Predicting Behaviors to Reduce Toxic Chemical Exposures Among New and Expectant Mothers: The Role of Distal Variables Within the Integrative Model of Behavioral Prediction.
abstract: There is a growing body of evidence linking childhood exposure to environmental toxins and a range of adverse health outcomes, including preterm birth, cognitive deficits, and cancer. Little is known, however, about what drives mothers to engage in health behaviors to reduce such risks. Guided by the integrative model of behavioral prediction, this study surveyed women who were pregnant and/or had children younger than 7 years (N = 819) to identify the factors that determine engagement in behaviors to reduce childhood exposure to toxic chemicals in the environment. Structural equation modeling pertaining to three different environmental toxins-bisphenol A, arsenic, and pesticides-demonstrated that perceived normative pressure was the primary determinant of behavior across all three models. Additionally, we identified two key distal variables-perceived risk and information seeking-that not only increased the model's predictive power but also consistently and positively predicted perceived social norms regarding exposure reduction behaviors. Findings also suggest important differences across these behaviors. Implications for health communication researchers and practitioners developing interventions, communication campaigns, and persuasive messages to promote prenatal and pediatric environmental health are discussed.
