Editing Personality test (section)

==Overview==
There are many different types of personality assessment measures. The [[self-report inventory]] involves administration of many items requiring respondents to introspectively assess their own personality characteristics. This is highly subjective, and because of item transparency, such Q-data measures are highly susceptible to motivational and response distortion.<ref>Boyle, G.J. (1985). Self-report measures of depression: Some psychometric considerations. ''British Journal of Clinical Psychology, 24'', 45-59.</ref> Respondents are required to indicate their level of agreement with each item using a [[Likert scale]] or, more accurately, a Likert-type scale. An item on a personality questionnaire, for example, might ask respondents to rate the degree to which they agree with the statement "I talk to a lot of different people at parties" on a scale from 1 ("strongly disagree") to 5 ("strongly agree").

Historically, the most widely used multidimensional personality instrument is the [[Minnesota Multiphasic Personality Inventory]] (MMPI), a psychopathology instrument originally designed to assess archaic psychiatric [[nosology]].<ref>Helmes, E., & Reddon, J.R. (1993). A perspective on developments in assessing psychopathology: A critical review of the MMPI and MMPI-2.

In addition to subjective/introspective self-report inventories, there are several other methods for assessing human personality, including observational measures, ratings of others, projective tests (e.g., the [[Thematic Apperception Test|TAT]] and [[Rorschach inkblot test|Ink Blots]]), and actual objective performance tests (T-data).
