Description of the Test:
The EPP6 is the computerised adaptation of Eysencks Personality Profiler (EPP) within the Vienna Test System. The adaptation appears to be a straight implementation of the paper and pencil version of the EPP6 and complete functional equivalence is assumed although no evidence is provided to support this assumption. Eysenck theory of personality is well known. It seeks to explain how personality develops and the biological basis underlying it. The theory sets out a system that describes and measures the main traits and higher order constructs of personality. The EPP6 is the last in the development of a series of personality questionnaires which began in 1952 with the Maudesley Medical Questionnaire, was developed into the Eysenck Personality Inventory in 1964, followed by the Eysenck Personality Questionnaire in 1975 and the revised Eysenck Personality Questionnaire in 1985. Finally the Eysenck Personality Profiler was first developed in 1988 with the Eysenck Personality Extraversion Profiler (v6) in 1999. The instrument is a multi scale, trait inventory, which measures through forced choice responses (yes, no and cannot decide) the three higher order constructs which according to Eysencks theory describe personality: extraversion-introversion, emotionality (neuroticism) and adventurousness-cautious (psychoticism). In addition there is a dissimulation (or lie scale) and the computer system generates the number of cant decide choices if this goes above 5% then a warning is issued about the reliability of the profile. The long version of the test (S1) has 440 items assessing 21 sub-scales, the short form (S2) consists of 200 items measuring 9 sub-scales. The following are the scales measured by the long version, with those included in the short version indicated by an asterisk: Extraversion Introversion E1: Activity * E2: Sociability * E3: Expressiveness E4: Assertiveness * E5: Ambitiousness E6: Dogmatism E7: Aggressiveness Emotionality (Neuroticisim) N1: Low Self Esteem * N2: Unhappiness * N3: Anxiousness * N4: Dependency N5: Hypochondriasis N6: Guilt N7: Obsessiveness Adventurousness Caution (Psychoticism) P1: Risk-taking * P2: Impulsiveness * P3: Irresponsibility * P4: Manipulativeness P5: Sensation Seeking P6: Toughmindedness P7: Practicality
