The TCI is designed to be a comprehensive inventory of personality. It is used by psychiatrists, psychologists, coaches, corporations, and individuals. Below are alternative forms of the TCI for various age and clinical groups, as well as for different formats and respondents.
The TCI-R is recommended for full individualized personality assessment in adults or adolescents 15 or older. It provides most precise measurement of the 7 higher order dimensions and 29 subscales.
The Short TCI-R is recommended for research applications in which time available for subjects may be limited. It provides reliable measurement of the 7 higher order dimensions and most, but not all, of the subscales.
The TCI is the original true-false version for adults and includes a validity analysis that makes it specially useful for forensic applications or situations where the subjects may have motivation for misrepresentation of their self-image. It provides reliable measurement of 7 higher order dimensions and 25 subscales (persistence is measured by one short scale rather than by 4 as in the TCI-R, and reward dependence is measured by 3 scales rather than 4 as in the TCI-R).
The Tridimensional Personality Questionnaire (TPQ) is the original self-report form that measures only temperament dimensions. It provides reliable measures of 3 dimensions of temperament (Harm Avoidance, Novelty Seeking, and Reward Dependence), including 11 subscales, plus one short scale for persistence. Character is not measured, so level of maturity versus personality disorder is not evaluated.
The Junior TCI (JTCI) is the self-report form for children 10-14 years of age. It provides reliable measures of 7 higher order dimensions.
The Junior TCI-he/she is the form for description of children 5-14 by those who know them well, such as parents or teachers. It provides reliable measures of 7 higher order dimensions.
The Pre-school TCI (PSTCI) is the form for description of preschool children (ages 2-4 years) by those who know them well, such as parents, care-takers, pre-school teachers. It provides measures of 7 higher order dimensions.
