Personality Pattern Inventory: Evaluation of Personality Architecture


Personality Pattern Inventory is a profiling tool, part of the Process Communication Model that evaluates the human personality architecture originally developed by American psychologist Dr. Taibi Kahler in 1976.

Since its discovery, the Personality Pattern Inventory has been used by NASA as the main tool in the selection of candidate and has over 1 million worked profiles and over 40 years of scientific research and validation.



The PPI can be used both individually and at group or organization level (composite profiles) and measures the following:

Perceptions: The six ways (thoughts, opinions, emotions, actions, reactions and reflections) in which we filter and mentally process reality and how energized is each of them in us;

„Currency” used in communication: What each person focuses on in communication and interaction (logic, values, compassion, humor, imagination or charm);

Stengths : What are the native strengths that spring from each person’s personality and which are the areas of improvement;

Interaction styles/ management: Ranking a person’s preferences for a certain style of management (autocratic, democratic, benevolent or laissez faire);

Personality Parts: At the level of words, tone, gesture, posture and mimics, how they prefer each person to communicate;

Environment preferences: Hierarchy of a person’s preferences to spend time alone, in groups, from one group to another or one to one;

Fundamental psychological needs: Which are the main sources of motivation for each individual;

First degree distress sequence  – Specific alarm signals that indicate psychological fatigue and / or unsatisfactory psychological needs;

Second degree distress sequence  – The non-constructive behaviors to which each person is susceptible to severe stress and their correlation with the positive psychological need in the back;









Personality Pattern Inventory provides you with a scientific analysis of one’s inner life and proposes the most effective approaches to communication, interaction, motivation, and conflict management.

In specific terms, the PPI will help you:

  1. Speak with each person using her own language;
  2. Understand what is important and what each person focuses on;
  3. Quickly determine the strengths of each person’s personality and on what you can build upon;
  4. Choose the most effective style of interaction and management in relation to that person.
  5. Understand the particular contexts in which an individual can act productively;
  6. Understand the most important needs of one’s personality and how to satisfy them;
  7. Observe the first (unconscious) signals that you are heading to a conflict with the person you are interacting with;
  8. Understand distress sequences and non-constructive behaviors of people around you and manage them successfully;
