General Description of Test:The MBTI is a personality questionnaire based on the theories of Carl Jung. It was in Jung’s theories that Isabel Myers found a vehicle to progress Katherine Briggs’ ideas and her own belief that it is of benefit to people to recognise their individual personality types, and how these differ from those of other individuals. The MBTI is the practical result of research by Myers and her colleagues. The end product is an untimed questionnaire which asks respondents to choose between two opposing courses of action, or two words, depending on what they feel is closest to their natural preference. Prior to the launch of Step-1 in 1998, the publishers undertook a programme of research to redevelop the MBTI with the aim of producing a form that would be more accurate for detecting ‘best-fit type’ in European English-speaking groups. Step-1 retains most of the features of Form G (the forced-choice item format, the same approach to scoring and the same preference score meanings), but it now contains 88 items (87 scored; 66 from Form G plus substitutes for items that did not work’ in the UK, taken from Myers’ Form J questionnaire). Thirty-one of the original unscored items have been dropped. The scoring system has also been simplified by eliminating the gender-specific scoring for Thinking-Feeling (see body of review) and all of the items now have only two forced-choice options. The results of a large-scale UK standardisation study are available, which is described in the MBTI Step-1 European English edition of the manual supplement. The administrator transfers the results to a report form, which is discussed with the respondent. There are options for computer scoring and report generation, in which case the report can be used as the basis for the discussion. The MBTI measures four preferences: 1 Extraversion or Introversion – the focus of an individual on the outside world of people and things (E) or the inner world of thoughts and ideas (I); 2 Sensing or Intuition – the preference of an individual to rely on the five senses for perceiving the world around (S) or to use intuition or ‘sixth sense’ to focus on relationships and possibilities (N); 3 Thinking or Feeling – the way in which a person prefers to exercise judgement, that is, the preference to focus on a logical analysis (T) or on personal convictions and values (F); 4 Judging or Perceiving – the preference to deal with the outside world through a judging process, either thinking or feeling (J) or a perceiving process of either sensing or intuition (P). People’s four preferences classify them into one of 16 types. Descriptions are given of the characteristics of people of each of the 16 types. Each type is described as having positive qualities and strengths, as well as possible development needs. The MBTI type information may be used in counselling, career counselling, individual development, education, and team building. The type interpreter’s task is to provide ways in which people can understand their best and most trustworthy ways of functioning. The substantial and comprehensive manual is accompanied by a range of interpretative guides and other support products for the user. The MBTI Step II (the re-launched form K) has been developed to include the option of an ‘expanded analysis’. This is a process whereby information can be generated from an individual’s responses to indicate preferences on the 20 sub-scales. The MBTI Step II will be reviewed separately.
