Constructs vary considerably in their breadth. Some constructs are very broad and subsume considerable variation in content, whereas other constructs are much narrower in the content subsumed. This dimension is often discussed under the rubric of “bandwidth vs. fidelity” (Clark & Watson, 1995).
Broad constructs are those that cover a wide range of behavioral exemplars, meaning that assessment of a broad construct should be based on sampling from several subdomains of content.
Broad construct examples:
Narrower constructs cover a much narrower range of behavioral content.
