In this chapter, we provide an overview of the research process insofar as it is relevant to peace psychology. To begin, different research goals and designs are introduced. Subsequently, we discuss different quality criteria, sampling techniques, as well as methods of data collection and analysis. In doing so, we cover aspects of both qualitative and quantitative methodology. The chapter is complemented with various examples of studies from the field of peace psychology. Where applicable, we refer to methodological particularities specific to the area.
