Document Summary
Structured (objective) personality test vs. projective personality test. Logically deduce the type of content that should measure the characteristic to be assessed. Begins with a theory about the nature of the particular characteristic to be measured. Attempts to create a homogeneous scale and, toward this end, may use statistical procedures such as item analysis. Empirical strategies: rely on data collection and statistical analyses to determine the meaning of a test response or the nature of personality and psychopathology, criterion group strategy. The approach attempts to determine which items discriminate the criterion and control groups. Begin with a criterion group, who share the same personality traits, such as leadership or schizophrenia. Administer a group of item to criterion group and control group, which represent the general population. Then try to find the contrast between two groups. Cross-validate the scale by checking how well it distinguishes an independent criterion sample.
