For example, the concepts of intelligence and motivation are used to explain phenomena in psychology, but neither is directly observable. A hypothetical construct differs from an intervening variable in that it has properties and implications which have not been demonstrated in empirical research. These serve as a guide to further research.
[1] [2] [3] Construct validation is the accumulation of evidence to support the interpretation of what a measure reflects. [1] [4] [5] [6] Modern validity theory defines construct validity as the overarching concern of validity research, subsuming all other types of validity evidence [7] [8] such as content validity and criterion validity.

An operational definition is designed to model or represent a concept or theoretical definition, also known as a construct.Scientists should describe the operations (procedures, actions, or processes) that define the concept with enough specificity such that other investigators can replicate their research.
In psychology, a construct, also called a hypothetical construct or psychological construct, is a tool used to facilitate understanding of human behavior. A psychological construct is a label for a domain of behaviors. Behavioral sciences use constructs such as conscientiousness, intelligence, political power, self-esteem, and group culture.
A concept model (a model of a concept) is quite different because in order to be a good model it need not have this real world correspondence. [3] In artificial intelligence, conceptual models and conceptual graphs are used for building expert systems and knowledge-based systems ; here the analysts are concerned to represent expert opinion on ...
A theoretical definition of a term can change, over time, based on the methods in the field that created it. Without a falsifiable operational definition, conceptual definitions assume both knowledge and acceptance of the theories that it depends on. [1] A hypothetical construct may serve as a theoretical definition, as can a stipulative ...
Construct validity refers to the extent to which operationalizations of a construct (e.g., practical tests developed from a theory) measure a construct as defined by a theory. It subsumes all other types of validity. For example, the extent to which a test measures intelligence is a question of construct validity.
The concept of construal is not a new one, and the components of construal can be seen in the works of many past psychologists including Kurt Lewin's recognition of the importance of a subjective reality and its effect on one's personal significance; Kurt Koffka's theories of gestalt psychology; Brunswik's emphasis on subjective distinction ...
