Effective Characterizing

Are you looking for an efficient solution to improve your Investigative Interviewing Skills?

The key features of the Enhanced Investigative Interviewing Training Program using the Four Temperament (DISC) Model of Human Behaviour include the ability to understand human dynamics, read people effectively, and decern people’s preferred communication style. You’ll also learn how to ask powerful questions that elicit information to gain insights – the ability to see things others overlook. Additionally, you’ll master the art of listening and easily establish and maintain rapport. 

One of the biggest benefits of Enhanced Investigative Interviewing using the Four Temperament (DISC) Model of Human Behaviour is improving in-person and online meeting mechanics. You’ll learn how to structure your interviews effectively and keep them on track, saving you valuable time and resources. You’ll also develop cultural awareness, allowing you to navigate different cultural norms and expectations.

A 3-Day Workshop to Learn The Skills of Interviewing, Debriefing, and Elicitation

People exhibit unconscious symptoms (clues and cues) that you can read to determine if they are being open and honest or evasive and untruthful. Using EII principles and guidelines, you can reliably assess a person’s personality traits, pinpoint areas that need further probing, overcome resistance and properly evaluate the reliability of the information you’ve received from an individual.


Workshop Program Content:


Day 1 - RELATIONSHIP via DISC Model of Human Behaviour

Based on the DISC Model of Human Behaviour, this module increases self-awareness regarding personality viewpoints and perspectives in order to improve relationships and minimize conflicts. In this module you will:

Discover the principles of effective communication and interaction

Experience where misunderstanding can take place

Apply strategies to establishing and maintaining rapport


Day 2 - MESSAGE via Behavioural Symptom Analysis (BSA)

BSA is the study of the way in which people act, speak and behave in various circumstances. From this study, patterns of behaviour can be built to enable predictions and deductions about an individual. This analysis is also particularly valuable in helping to evaluate truth and deception. This module addresses the following skills:

Vocal element: how we say those words

Verbal element: the words we choose to use

Non-verbal element: the posture, gestures and movements we make while talking - often called "body language"


Day 3 - CONTEXT via Cultural and/or Situational Awareness

The final key is context-adopting and applying both the DISC and BSA modules within a given context or situation. This module provides valuable insights, skills and strategies for communicating effectively across cultures, in addition to showing how culture affects the IDE process. In this module you will:

Explore the relationship between cultures and communication styles

Increase awareness of cultural perspectives and their effect on behaviour

Learn skills and strategies for effective communication
