Latent class analysis (LCA) is a statistical method used to identify subtypes of related cases using a set of categorical or continuous observed variables. Traditional LCA assumes that observations are independent. However, multilevel data structures are common in social and behavioral research and alternative strategies are needed. In this…

Over the last decade the daily experience of adolescents has been transformed by developments in electronic media, including the computer, the Internet, and cell phones.

Because health behavior is often concerned with dynamic constructs, a longitudinal approach to measurement is needed. The Longitudinal Guttman Simplex (LGS) is a measurement model developed especially for dynamic constructs exhibiting cumulative, unitary development measured longitudinally. Data from the Television Smoking Prevention Project, a…

While data on the onset of cigarette smoking among younger adolescents has been investigated extensively, it is less clear whether the same social factors influence older adolescents.

Basic research and programs in substance abuse dealing directly with rural and small town populations lag far behind those aimed at urban groups, in both quality and quantity. A study was conducted to identify factors related to substance use by a preadolescent and early adolescent rural and small town population. Data were collected from 496…

The results indicate that…

Longitudinal studies conducted with children typically experience non-response problems that can make substantial inroads on sample size and introduce bias into the analysis. Three methods for limiting non-response in school-based research programs were assessed: (1) asking parents to return consent forms only if they do not want their children to…
