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.
Validity evidence based on nomological validity is a general form of construct validity. It is the degree to which a construct behaves as it should within a system of related constructs (the nomological network). [3] Nomological networks are used in theory development and use a modernist [clarification needed] approach. [4]
[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.

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.
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.
Operationalization is part of the empirical research process. [17] An example is the empirical research question of if job satisfaction influences job turnover. Both job satisfaction and job turnover need to be measured. The concepts and their relationship are important — operationalization occurs within a larger framework of concepts.
Constructivism is a view in the philosophy of science that maintains that scientific knowledge is constructed by the scientific community, which seeks to measure and construct models of the natural world.
Bas van Fraassen is nearly solely responsible for the initial development of constructive empiricism; its historically most important presentation appears in his The Scientific Image (1980).
