Why use the TCI?
The Temperament and Character Inventory (TCI) provides a thorough description of a person's personality and emotions -- that is, the usual way they think, feel, and act. Everyone is unique in responses to life experiences and relations with other people. The TCI gives a profile of these responses that can help you understand yourself or another person, such as your child, spouse, friend, or anyone else you know well.

The TCI is the most advanced and comprehensive test of personality available. It is the only test of personality that provides a comprehensive profile that is based on what is currently known about the biology, psychology, and development of personality and emotions.

Other tests ignore the differences between temperament (the basic emotional predispositions with which we are born) and character (what we make of ourselves intentionally). No other test measures all seven basic dimensions of personality, which are needed to understand the development of our capacity to work, love, and understand the meaning of life, as well as to understand the basic emotions we feel that may complicate mature development.

The TCI has many applications that are useful to private individuals, clinicians, and in the workplace in many countries. There are different forms for people of different ages, speaking different languages, and depending on whether you are describing yourself or another person, such as a child, spouse, friend, or enemy whom you want to understand better. The TCI has been given to many large groups of people in the general population and many people with different kinds of health problems.

Quantitative scoring of the profiles allows comparison to other people. It also allows predictions about situations that are difficult or stressful, and ways of dealing with those difficulties. It can help distinguish people who are leaders, cooperative team players, or loners.

The TCI profiles useful information about responses to drugs (like antidepressants and tranquillizers) and to psychotherapy (like cognitive-behavioral, psychodynamic, or meditation-based therapy) . (It can help predict who will benefit from an antidepressant, which antidepressant is most likely to give benefit, and what other medications may be helpful as adjuncts in refractory cases.) The TCI can be used to measure progress with treatment.

After the test is taken, scoring and interpretation is provided immediately using computerized analyses that are sufficient for most individuals and clinical professionals. However, further individualized consultation is available if requested and can be provided by the psychiatrists and psychologists in the Center for Psychobiology of Personality.
