From resolving misunderstandings with colleagues to negotiating complex deals and leading project teams, you use influence as part of your everyday work life. While there are several different styles of interpersonal influence, research shows that assertive behavior has the greatest impact on individual success and organizational performance. The good news is that influence is a learned skill, and with the right training, some self-discovery, and a healthy dose of practice, people can develop their ability to be assertive.

The Interpersonal Influence Inventory (III) is designed to create an awareness of the behaviors people use when they attempt to influence others. The purpose of the Inventory is to allow respondents to recognize their own style of influence and work toward developing a more effective style.

How it works

The Interpersonal Influence Inventory assessment and workshop is an eye-opening learning tool that reveals a preference for one of four dominant styles: openly aggressive behavior, concealed aggressive behavior, passive behavior, or assertive behavior. An HRDQ bestseller for more than 20 years, the Interpersonal Influence Inventory is a combination of self-assessment and training workshop that has helped thousands of people:

  • Identify their interpersonal influence style.
  • Learn how they come across to others.
  • Work toward becoming more effective communicators.

The core of the Interpersonal Influence Inventory is derived from leadership and persuasive communication literature. The literature suggests that direct expression of one’s views, coupled with consideration for others, can help improve individual and organizational functioning. This type of behavior is often called assertive behavior.

Learning outcomes

By the end of this workshop, participants will be able to:

  • Identify their preference for one of four personal influence styles: passive, assertive, openly aggressive, or concealed aggressive.
  • Learn why assertive behavior is the one style that always yields positive results.
  • Understand how other influence styles can hamper interpersonal communication.
  • Discover the behavioral cues that signal each style.

Uses and applications

The Interpersonal Influence Inventory can be used as a stand-alone learning instrument or part of a more comprehensive training program.
The assessment is effective as a:

  • Tool to develop assertiveness skills.
  • Centerpiece of a communication workshop.
  • Component of a leadership development program.
  • Diagnostic tool for one-on-one coaching.
