A Science-Backed Tool to Understand How You are Perceived

The Interpersonal Dynamics Inventory

The Interpersonal Dynamics Inventory (IDI) is a multi-rater behavioral assessment tool that combines several perceptions to measure aspects of behavior rather than intent. IDI's results teach us how our behavior impacts others, improve our ability to work with and influence others, and help us understand what motivates our own and others' interpersonal behavior.

Why IDI Works

IDI has three unique characteristics that are crucial for feedback to have a positive effect on our behavior.

IDI calls on the important people in your life.

IDI is linked to a specific context. 

IDI relates to your professional role, not just your personality.

Asking others for feedback generates respect. Your respondents invest in the process by describing how they experience you, which creates a "contract" between you and them. You become, so to speak, "obliged" to do something with the feedback you receive and this greatly increases the chances that you will actually do it.

IDI does not tell you who you "are". Your IDI profile is a snapshot of how people experience you in a given context. Because the feedback is specific and applies to a particular context, it becomes easier to transform the feedback into insights and concrete actions that you perceive as important.

Developing IDI For Today's Workplaces

The Interpersonal Dynamics Inventory (IDI) was initially developed in the United States by Dr. Richard E. Zackrison, Ph. D. in 1977. His decades-long work resulted in the instrument as it exists today, which emphasizes the interpersonal tendencies of human nature while remaining sensitive to the varying behavioral norms of cultures around the world. 

Unlike industry tools like the Meyers-Briggs, the Interpersonal Dynamics Inventory draws on both self-perception and input from significant others in the workplace, for instance, co-workers, supervisors, and subordinates. The resulting feedback allows an individual to understand his or her social style and role in order to strengthen relationships and leadership.

Throughout the years, the IDI tool has been consistently tested and adjusted as needed to ensure its foundational approach can translate to modern users and practice. The IDI tool is now fully operational in a digital format in over 24 languages while continuing to employ the groundbreaking outcomes of decades of behavioral-based research.
