Description of the Test:
The TDI (Type Dynamics Indicator) together with its subset of items the LSI (Learning Styles Indicator) forms part of The Type Mapping system published by Team Focus. This is an approach to using Psychological Type which is firmly based on the writings of the Swiss psychologist Carl Jung.
It is described as a Jungian Type indicator, because its rationale is said to fit explicitly with Jung’s concepts of dynamic interplay, change over lifespan and individuation. The author of the questionnaire argues its primary purpose is to assist with individuation aiding people to gain insight, grow and develop as individuals and to be more effective and satisfied with their lives and relationships.
Those familiar with the Jungian approach to personality will recognise the four dichotomies Extraversion-Introversion, Sensing-Intuition, Thinking-Feeling and Judging-Perceiving and the 16 types associated with a test taker’s preferences. However, the aim of the TDI is not to report a fixed set of letters that represent the test taker’s personality, but to help people understand different aspects of their personality and so help them to become more behaviourally flexible and to adapt to changing circumstances.
There are three forms of the test, Form C the closed version available for on-line or pencil and paper administration by trained practitioners. It is a 64-item questionnaire composed of phrases and word pairs rated on a 6-point scale. It takes 10-20 minutes to complete. The questionnaire is also available where each question is answered in two mind-sets – ‘the way it is’ and ‘the way I want’. This version takes around 15-25 minutes.
Form O is an open version available online for controlled administration. The open version is the same as form C but uses a different set of 64 items.
And Form, P a pictorial form initially intended for use with young people but with subsequent wider application. It employs 56 pictures using a 6-point scale and takes 8-12 minutes.
Completion of any of the versions yields scores on the four dichotomies summarised into one of 16 types.
A range of computer generated reports presenting the results both numerically and graphically as well as in narrative form are available on completion.
In summary, the authors believe the TDI to be a quick and easy to use reliable measure using a recognised model. It is intended for use in self-awareness, careers and relationship development.
