What You Cannot See Can Still Kill You: On the Use of Latent Constructs

Nursing research relies heavily on the use of latent constructs to describe and understand phenomena that cannot be measured through direct observation.

In this sense, latent constructs represent real phenomena that cannot always be seen directly.
