Life Styles Inventory™ with Item-Level Feedback (LSI ILF)

Research and Development by J. Clayton Lafferty, Ph.D. (LSI) and Robert A. Cooke, Ph.D. (ILF)


Identify targets for behavioral change to improve interpersonal relations, increase effectiveness, and develop leadership potential

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 relationships between personal, management, and leadership styles and effectiveness. Research over the past four decades, based on thousands of data points, demonstrates that the LSI styles are related to various indicators of individual effectiveness and important outcomes such as managerial effectiveness and openness to feedback (as reported by others), self-reported stress, salary, and organizational level.

The ILF report provides a deeper understanding of the personal orientations and behavioral styles measured by the LSI. Individuals are provided with detailed item-by-item feedback that offers otherwise unavailable information on the specific behaviors on which they should focus to strengthen Constructive styles and reduce Defensive tendencies. Their results are compared to those for 14,000 individuals in our new international norming data set. To complement the ILF, additional results (self-reports and descriptions by others) at the style level are presented in a new Summary Grid to identify Confirmed Strengths, Unrecognized Strengths, Stumbling Blocks, and Blind Spots.
