Developed by psychologist and University of Washington professor Allen L. Edwards, the Edwards Personal Preference Schedule (EPPS) is a forced choice, objective, non-projective personality inventory. The target audience in between the ages of 16-85 and takes about 45 minutes to complete. 〔 Edwards derived the test content from the human needs system theory proposed 〔Kaplan, R. M., & Saccuzzo, D. P. (2009). "Psychological testing: Principles, appoications, and issues" (7th ed.). Belmont, CA: Wadsworth〕 by Henry Alexander Murray, which measures the rating of individuals in fifteen normal needs or motives. The EPPS was designed to illustrate relative importance to the individual of several significant needs and motives. It is useful in counseling situations when responses are reviewed with the examinee. 〔 Educational Testing Services. (1992). "The ets test collection catalog:Affective measures and personality tests", Arizona: Oryx Press. 〕 ==Murray's Theory of Psychogenic Needs== Murray's system of human needs has influenced the making of personality tests for years. 〔 By incorporating his theory into personality testing, one can determine how one may act in a specific situation, as an employee, student, parent... The list goes on and on... Following is an overview on Murray's theory. American psychologist Henry Murray developed a theory of personality that was organized in terms of motives, presses, and needs. Murray described a need as a potentiality or readiness to respond in a certain way under certain given circumstances. Theories of personality based upon needs and motives suggest that our personalities are a reflection of behaviors controlled by needs. While some needs are temporary and changing, other needs are more deeply seated in our nature. According to Murray, these psychogenic needs function mostly on the unconscious level, but play a major role in our personality. 〔 Cherry, Kendra. (2012). "Murray's theory of psychogenic needs". Retrieved November 21, 2012, from http://psychology.about.com/od/theoriesofpersonality/a/psychogenic.htm〕 The Personality Research Form and the Jackson Personality Inventory are also structured personality tests based on Murray's theory of needs but were constructed slightly differently than the EPPS in hopes of increasing validity. 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Edwards Personal Preference Schedule」の詳細全文を読む スポンサード リンク
