Personality inventory scales typically contain several different items to assess the various different aspects of the trait to be measured, and to obtain a good measurement of what is common to the items (i.e., the trait to be assessed). This approach increases the reliability and validity of the measurement. Option B) is incorrect as catching people in an inconsistent pattern of responding is not the primary goal of having multiple items in the scale, although it can be a useful side-effect. Option D) and E) are also incorrect, as distracting respondents from the real purpose of the inventory is not a common or ethical practice.
