We surveyed randomly selected parents in one state (N = 1, 081) to examine sources they used to gain child‐rearing information. On average, parents used five sources, most commonly books and family members. Usage patterns generally followed the “digital divide” perspective whereby higher education levels were associated with greater usage. Logistic regression results of Internet use showed, however, that being younger and unmarried increased the likelihood of use, indicating the Internet's potential for reaching potentially vulnerable parents.
Human behavior is dynamic, influenced by changing situations over time. Yet the impact of the dynamic nature of important explanatory variables on outcomes has only recently begun to be estimated in developmental models. Using a risk factor perspective, this article demonstrates the potential benefits of regressing time-varying outcome measures on time-varying explanatory measures in longitudinal models. The authors apply event history analysis techniques to demonstrate a methodological strategy that accounts for changes over time in two family risk factors for high school graduation. In a sample of 686 low-income youth attending school in an urban district, the authors found that maternal employment status and income are significant predictors of high school graduation only when conceptualized and measured as time-varying influences. The implications for policy and practice and, from a methodological perspective, for the use of time-varying explanatory variables in event models are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
