McKinley at the University of Minnesota.  The most widely researched and clinically used of all personality tests  Developed to identify emotional disorders  This is one of the most frequently used personality tests in mental health.

  25. 25. Minnesota Multiphasic Personality Inventory  The MMPI-2 is most commonly used by mental health professionals to assess and diagnose mental illness.  The MMPI-2 has been utilized in other fields outside of clinical psychology. The test is often used in legal cases, including criminal defense and custody disputes.

Millon Clinical Multiaxial Inventory (MCMI )  It has been designed for adults (18 years and older) who have a minimum of an eighth-grade reading level.  The MCMI is one of the few self-report tests that focus on personality disorders along with symptoms that are associated with these disorders.

  31. 31. PROJECTIVE TECHNIQUES  Projective techniques involve asking subjects to interpret or fill in visual stimuli, complete sentences, or report what associations particular words bring to mind.  Because of the leeway provided by the tests, subjects project their own personalities onto the stimulus, often revealing personal conflicts, motivations, coping styles, and other characteristics.
  32. 32. Rorschach inkblot test Hermann Rorschach (8 November 1884 – 1 April 1922)

  34. 34. Rorschach inkblot test Test scores are based on several parameters: 1) what part of the blot a person focuses on 2) what particular details determine the response; 3) the content of the responses (what objects, persons, or situations they involve); 4) the frequency with which a particular response has been given by previous test takers
  35. 35. Rorschach test
  36. 36. Thematic Apperception Test (TAT)  Introduced at Harvard University in 1935 by Henry Murray.  Test takers look at a series of up to 20 pictures of people in a variety of recognizable settings and construct a story about what is happening in each one. They are asked to describe not only what is happening at the moment shown in the picture but also what events led up to the present situation and what the characters are thinking and feeling.
  37. 37. Thematic Apperception Test (TAT)  Its adherents assert that the TAT taps a subject's unconscious to reveal repressed aspects of personality, motives and needs for achievement, power and intimacy, and problem-solving abilities.
  38. 38. Thematic Apperception Test (TAT)  The subject is asked to tell as dramatic a story as they can for each picture presented, including the following: ? what has led up to the event shown ? what is happening at the moment ? what the characters are feeling and thinking ? what the outcome of the story was
  39. 39. TAT PROCEDURE
  40. 40. Some TAT cards

  42. 42. Thematic Apperception Test (TAT) USES OF TAT  Individual assessments for employment in fields requiring a high degree such as law enforcement, military leadership positions.  For diagnosis in order to match psychotherapy best suited to patients personalities.  Forensic purposes in evaluating the motivations and general attitudes of persons accused of violent crimes.  Research into specific aspects of human personality, most often needs for achievement, fears of failure, hostility.
  43. 43. sentence completion test  Specifically for children or adolescents.  Subjects are asked to complete sentences with such open-ended beginnings as “I wish . . .” or “My mother . . .”  Same sentence beginnings are shown to different test takers.  There are no norms for comparing their answers to those of previous subjects.
  44. 44. CREATE DRAWINGS  (Draw a person test)  complete a story.
  45. 45. NEUROPSYCHOLOGICAL ASSESSMENT  Luria- Nebraska battery  Halsted- Reitan battery  Michigan neuropsychological battery  Shipley Institute of Living Scale  NIMHANS neuropsychological battery.
