A personality test is a questionnaire or other standardized instrument designed to reveal aspects of an individual's character or psychological makeup.The first personality tests were developed in the 1920s and were intended to ease the process of personnel selection, particularly in the armed forces.Test items are then selected or eliminated based upon which will result in the strongest internal validity for the scale.Measures created through deductive methodology are equally valid and take significantly less time to construct compared to inductive and empirical measures.
Development of personality tests tends to be an iterative process whereby a test is progressively refined.
This allows researchers to analyze natural relationships among the questions and label components of the scale based upon how the questions group together.
Several statistical techniques can be used to determine the constructs assessed by the measure.
The items created for an inductive measure to not intended to represent any theory or construct in particular.
Once the items have been created they are administered to a large group of participants.
The clearly defined and face valid questions that result from this process make them easy for the person taking the assessment to understand.
