ABSTRACT
This chapter deals with the one take-home, bottom-line message for both sport and exercise psychology scholars and our measurement colleagues: Identifying our research questions, or achieving conceptual clarity, is the source and solution for our measurement, statistics, and design issues. It reviews the progress sport psychology has made with measurement, statistics, and design within this framework; highlight some current issues; and discuss directions and options. Some of the advances apply to other content areas within exercise and sport science, but the chapter focuses on progress in measures and research related to individual differences. Many of the most important constructs of sport and exercise psychology are multidimensional, and recently we have used multidimensional conceptual frameworks and measurement procedures to develop appropriate multidimensional measures. It purposely focuses on the psychological measurement issues, because they are the most unique to the sport and exercise psychology area, and because they are indeed major issues.
