"This Handbook provides a compendium of research methods that are essential for studying interaction and communication across the behavioral sciences. Focusing on coding of verbal and nonverbal behavior and interaction, the Handbook is organized into five parts. [bullet] Part I provides an introduction and historic overview of the field. [bullet] Part II presents areas in which interaction analysis is used, such as relationship research, group research, and nonverbal research. [bullet] Part III focuses on development, validation, and concrete application of interaction coding schemes. [bullet] Part IV presents relevant data analysis methods and statistics. [bullet] Part V contains systematic descriptions of established and novel coding schemes, which allows quick comparison across instruments. Researchers can apply this methodology to their own interaction data and learn how to evaluate and select coding schemes and conduct interaction analysis. This is an essential reference for all who study communication in teams and groups"-- "An overview of available software that can assist with interaction analysis is also part of this section. Part IV presents concrete data analysis techniques and relevant statistics that can be applied to further analyze and present coded data. The chapters focus on frequency analyses, sequential analyses, as well as special problems in interaction research, such as interdependence of data and the analysis of multiple levels. Several of the chapters also present quantitative and qualitative methods of visualizing coded data. Part V is comprised of a selection of coding schemes that can be used for different purposes in various research contexts"--
