Fifteen Factor Questionnaire +

Based on an extensively researched model, the 15FQ+ provides an in-depth assessment of the full sphere of human personality. It has been developed to ensure culture and gender fairness and has been adapted into over 20 languages. Building on the most current research, the 15FQ+ maintains the breadth of the original 16 personality factors first identified by Raymond B Cattell. It sets new standards for reliability and validity.

The 15FQ+ measures the fundamental building blocks of personality. These provide insight into how people typically think, feel and interact in ways that may be productive or counter-productive for your organisation.

For example the 15FQ+ can identify people who:

  • Crack under pressure
  • Lack motivation and drive
  • Create conflict and discord
  • Are insubordinate and defiant
  • Avoid decisions
  • Are rule breakers
  • Obstruct change
  • Are careless and error prone
  • Are cold and callous
  • Are needy and dependent
  • Are culturally insensitive
  • Are hostile and suspicious
  • Cope well with pressure
  • Are self starters
  • Resolve disagreements
  • Are team players
  • Are decisive and action-orientated
  • Are diligent and compliant
  • Embrace change
  • Are attentive to detail
  • Are participative and engaging
  • Are confident and self-assured
  • Are culturally sensitive
  • Are open and accepting


Having been completed by hundreds of thousands of people worldwide, the 15FQ+ is supported by an extensive evidence base attesting to its reliability, validity and culture fairness. It can be completed in paper and pencil format or online and offline using the GeneSys platform. It provides an in-depth assessment of a person’s strengths and development needs and is a powerful tool enabling you to select the right person for key positions in your organisation.

15FQ+ Reports

The GeneSys Integrated Assessment System generates profile charts and in depth expert narrative reports for decision-making and feedback. These describe an individual’s typical interpersonal behaviour, thinking style and ways of coping with stress. Extended reports include preferred Team Roles, Leadership, Subordinate and Selling Styles, and Career Themes. Reports focussing on competencies and emotional intelligence are also available.

Customised reports can be developed to focus on factors critical to your organisation. Interview prompts to further explore the match and mismatch between the individual and role requirements are also available
