An ongoing validation process is an important function in the development process of any behavioural profile analysis or any psychological profiling method, although few developers publish their findings.
Extended DISC International and FinxS systems are the exception and have recently produced their latest 2022 Validation Report as part of an ongoing and long-term validation process of the Extended DISC® Persona Management System, which, after several years of development, they released in 1994. Importantly, the systems are continually enhanced, developed, and expanded.
This latest report is a continuation of previous two-yearly reports that summarise a continuing study of the Extended DISC® instrument and the four key dimensions which it assesses (Dominance, Influence, Steadiness and Compliance).
The population was collected from the users of Extended DISC® and FinxS® Systems around the world and represents every age group, gender, organisation type and level in the same ratios that it is designed to be used.
The total population used in the research was an impressive:
- 1,237,505 for Behavioural Analysis,
- 51,202 for the Sales Capacity Assessment,
- 151,960 for Reasoning Analysis,
- In a total of 86 languages for Behavioural Analysis.
Reliability and validity characteristics of the Extended DISC® Persona Management System are analysed by using various statistical methods. The results, methods and basic theory are also briefly discussed in the report and compared with related earlier reports. This report is based on data collected in both normal training and consultancy situations and during special data collection processes conducted by Extended DISC International Ltd. and its associate consultants.
