Abstract
The usefulness of psychological testing lies in translating subjective awareness into an objective indicator. However, psychological tests are often ambiguous in their wording and scoring. The tester must construct understandable test items for the subjects of the test. Adjustment of the weighting of test items is an important issue that must be addressed when developing new appropriate tests. Therefore, a test developer must clarify the definitions of words and the weighting of items. On the other hand, it is essential for the tester to select an appropriate psychological test in consideration of the importance of subjective appraisal.
