Evolution & Model

The goal of the CPI260™ assessment, which is derived from the full 434-item California Psychological Inventory™ (CPI™) instrument, is to give a true-to-life description of the respondent in clear, everyday language (Gough & Bradley, 2005). The CPI260™ assessment measures 29 distinct psychological constructs grouped into 6 scale categories:

  • 7 Dealing with Others scales, focusing on the manner in which social participation is expressed
  • 7 Self-management scales, assessing self-discipline and acceptance of societal rules
  • 3 Motivations and Thinking Style scales
  • 3 Personal Characteristics scales
  • 6 Work-Related Measures scales, assessing disposition at work
  • 3 High-Order Measures scales, assessing personal orientations

The attributes of the CPI260™ instrument come from the language of everyday life, more specifically from what may be called “folk concepts” (Gough & Bradley, 2005). A folk concept is a construct about personality that all people everywhere use to comprehend their behavior and the behavior of others.

The CPI260™ instrument was designed to assess a sufficient number of folk concepts so that any consequential, recurring form of interpersonal behavior can be forecast, either from a single scale or from a combination of scales.


The tool is helpful for human resource and training personnel, as well as consultants involved in recruitment and selection, executive development and leadership training programs:

Recruitment: Skilled interviewers can ask questions that reveal some aspects of an applicant’s true behaviour, but the CPI260™ instrument, with its validity detectors, provides further insights with extraordinary accuracy.

Cost Savings: The CPI260™ instrument can be administered to large groups of people and computer-scored at very low cost.

Personal Growth: It uses non-technical language and describes behaviour in everyday terms that are easily comprehended.
