Life Styles Inventory™ (LSI)
On-Line and Self-Scoring Kits

Research and Development by J. Clayton Lafferty, Ph.D.


Beyond Emotional Intelligence: The LSI assesses and provides feedback on thinking and behavioural patterns that people can change to develop themselves along multiple dimensions, including their ability to understand and manage their emotions.

As one of Human Synergistics International’s first assessments, the LSI has helped millions of individuals gain self-awareness as well as an understanding of the relationship between personal, management, and leadership styles and effectiveness. Years of research using thousands of data points demonstrates that LSI styles are related to various indicators of individual effectiveness, including quality of interpersonal relations, openness to feedback, stress, salary, and organizational level.

The LSI specifically provides participants with feedback on Self (LSI 1) and Others’ (LSI 2) reports on personal orientations (Constructive, Passive/Defensive, and Aggressive/Defensive) and 12 specific thinking and behavioural styles associated with these orientations. Results are plotted on the Circumplex, which is normed against 14,000 individuals.

Participants complete the inventory on-line and receive a Simple Report based on their results, along with a 70-page Self-Development Guide. Alternatively, participants can complete a self-scoring inventory and receive their Self-Development Guide after they have scored their own inventory.

Human Synergistics also has available a number of LSI Enhancement Products  to help facilitators deliver an optimal learning experience for their participants.
