Life Styles Inventory™ (LSI) 40th Anniversary Edition

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 organisational-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.

Unique characteristics of the Life Styles Inventory™ (LSI)

  • Clearly describes the individual’s thinking (LSI 1) and behavior (LSI 2) in ways that promote Constructive change
  • Highlights similarities and differences between self and others’ views, leading to greater awareness and a focus on improvement
  • Meets academic and psychometric standards
  • Part of the Integrated Diagnostic System, which uses the Human Synergistics International Circumplex to link individual, manager, leader, team, and organisation behaviours
