Description:
<jats:p>This paper discusses the connections between nursing conceptual model concepts, middle-range theory, and situation-specific theory concepts, as well as between the theory concepts and how they are measured, that is, empirical indicators. Three types of empirical indicators are described—instruments, assessment tools, and interventions—and an example of each type is given. The paper’s central thesis is that a conceptual model concept is —or should be— the starting point for selecting or constructing an empirical indicator.</jats:p>
