Personal Style Inventory

Select Components:

Self-understanding is a necessary prerequisite for learning, growth, and getting along with others. Without it, no amount of formal training or on-the-job experience will enable people to reach their full potential - or improve their relationships with peers, coworkers, and managers. Blind to their own behavioral patterns, they will continue to trip over themselves in the same old ways. So, as a trainer, where do you begin?

A bestseller for more than 25 years, the Personal Style Inventory (PSI) test and training workshop is an accurate, statistically reliable personality-style assessment.

The online version of this assessment requires a subscription to the HRDQ Online Assessment Center.

How It Works

Based on Carl Jung's well-known personality theory, the Personal Style Inventory (PSI) identifies deep-seated style preferences along four paired dimensions:

  • Extroversion or introversion
  • Sensing or intuiting
  • Thinking or feeling
  • Perceiving or judging

The PSI makes it easy for people to "see" how they think, act, and feel. Plus, with eyes wide open, you've taken the first step toward improving your organization's communication, teamwork, leadership, and interpersonal relationships.

Using either the paper or online assessment, individuals respond to a series of 32 statements that relate to four paired dimensions. The result is a personality-style profile that is abbreviated by a combination of four letters symbolizing a preference for each dimension (i.e., ISTP = Introversion/Sensing/Thinking/Perceiving).

The paper assessment takes 15 minutes to complete, and we recommend you allow at least one hour for the interpretation of results, debrief, and action planning.

You can also extend the learning into two half-day training programs - one for individuals and one for teams - using the workshop instructions and PowerPoint presentation included with the facilitator guide. Trainer certification is not required to administer or facilitate the PSI.

What are the differences between the PSI and other Jungian-based assessments? Although these instruments use the same theory to measure personality style, the PSI asks individuals to assume a different frame of reference. While other Jungian-based assessments attempt to measure how people usually behave, the PSI measures how people prefer to behave. We believe this unveils a style closer to the true nature of the individual's personality style. Also, the PSI measures the relative strengths of each dimension, which is more helpful to individuals than either/or results presented by other Jungian-based assessments.

Uses and Applications

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

  • Centerpiece of a communication or leadership development program
  • Discussion starter for individual and personal counseling
  • Diagnostic instrument for career planning and job selection
  • Tool for mapping a team profile and improving group dynamics

Learning Outcomes

By the end of the workshop, participants will:

  • Identify an individual's dominant personality style
  • Learn about the 16 different personality styles
  • Discover the characteristics, strengths, and potential blind spots of each style
  • Understand how each style interacts with the others - and how to improve these relationships
  • Discover what types of tasks are suited - or not suited - to each personality style
  • Develop an action plan to improve performance and relationships with others
