Carl F. Jesness, Ph.D.



The Jesness Inventory has long been recognised as a classic measure for assessing personality and delinquent profiles.  Forty years of use has confirmed its utility to validly identify and understand youth and adults along multiple dimensions.  JI-R is a re-standardised version of this tool with new norms based on large and diverse samples of approximately 3,500 general population individuals, and 1,000 offenders/delinquents.

The JI-R is an easy-to-understand 160-item true/false questionnaire.  It is a tool that provides unique and powerful information about functioning across a variety of different areas.  It has 11 personality subtype scales that measure key traits and attitudes.  It also provides subtype evaluation with nine distinct subtype areas.  The subtype system has received strong endorsement from psychologists, social workers and counsellors.  The subtype system not only helps understand the individuals being assessed, but also leads to specific suggestions about treatment and risk.

The recent revision to Jesness Inventory was also used as an opportunity to introduce scales that relate directly to the relevant DSM diagnostic categories.  Two scales have been introduced to represent Conduct Disorder and Oppositional Defiant Disorder.  These new scales are fully normed, and add to the clinical diagnostic utility of the instrument.  The JI-R also contains validity scales to assess potentially invalid response patterns.  There is a Lie scale, as well as a Random Response scale that can be easily scored and interpreted when using the inventory.

The JI-R manual describes the development of the scales' new norms and validation and provides information on administration, usage and interpretation.  Scoring time is greatly reduced using the JI-R Scoring Templates. 

The JI-R was normed on 4,380 North American subjects - 3,421 non-delinquents and 959 delinquents.
