Instructions
Abstract or concrete qualities, properties, or characteristics of people, things, or
situations are described as variables. Variables are manipulated and/or measured in
quantitative research (Grove & Gray, 2019.) Variables are defined in two way -
conceptually and operationally. A conceptual definition is a broad, abstract definition of a
concept. This definition can be found in relevant literature about topics of interest. For
example, pressure injuries are defined as "localized damage to the skin and underlying soft
tissue usually over a bony prominence or related to a medical or other device." (Wound
Ostomy Continence Nursing Society, 2016). As defined here, there is no way to determine
change or outcomes in conceptual definitions. So, we operationalize the variables.
Instruments and tools are developed to make the concepts measurable by assigning
numbers for data analysis. Examples of pressure injuries
operational definitions could be using wound assessment tools, the Braden Scale, or the
NPUAP Staging tool.
Variables are classified in several ways and all studies use several types of variables.
