During the current reporting period, we developed and employed novel methods aimed at measuring, describing and modeling social networks. We developed a framework for the r psychometric evaluation of multiplex networks measuring a common relational construct. By multiplexity, we mean how different types of relationships overlap; this research helps to identify the underlying meaning in that multiplexity. A manuscript describing our framework is currently in press. We introduced a new method for explicitly modeling network structure within a multi-level framework. In all of our ongoing projects, we obtain multiple networks, with the goal of characterizing the variability of network structure across families. There are few methodological approaches for modeling these multi-level systems. To address this gap, we developed random effects exponential random graph models that allow us to test structural hypotheses, based on information obtained from multiple network systems. This approach advances currently available approaches by allowing for simultaneous estimation of structural parameters and accommodating networks that vary in size. Further, our work on network dynamics focuses on post-intervention changes in network composition on the one hand, and development of novel tools for the analysis of temporally unfolding micro-social processes on the other. We have been principal developers in a family of models broadly called Relational Events Models (REM) for social action. REMs can be employed to understand how a social behavior unfolds in time using an event history perspective. These novel methods have resulted in publicly available software through the R-CRAN and has been applied to animal models of interpersonal behavior. In addition to our research developing a measurement framework for social networks and multiplexity, we have examined the psychometric and measurement properties of genetic literacy scales commonly used in the literature. Our research examined genetic literacy within a large consumer panel representing the US adult population. We showed that commonly used scales measuring three dimensions of genetic literacy (familiarity, skills, and factual knowledge) fit the Rogers' hierarchy of knowledge. knowing this measurement property is important in contextualizing previous research using these scales and guiding measurement of genetic literacy in future research.

在本报告期间，我们开发并采用了旨在测量、描述和建模社会网络的新方法。我们开发了一个框架，用于多重网络的心理测量评估，测量一个共同的关系结构。所谓多重性，我们指的是不同类型的关系如何重叠；这项研究有助于确定这种多样性的潜在含义。描述我们的框架的手稿目前正在印刷中。
