SIGMA Personality is the evolution of two foundational personality assessments, the Personality Research Form (PRF) and the Jackson Personality Inventory – Revised (JPI-R).

Among the most highly cited personality assessments in the scientific literature, the impact and reputation of the PRF are evidenced through more than 1,500 references in published research.

The JPI-R boasts a similar legacy. SIGMA Personality, rigorously developed using best practices in test construction, builds on the legacy of the PRF, the JPI-R, the Five-Factor Model, and personality literature to deliver a comprehensive measure of personality in just 20 minutes.

Convenience – SIGMA Personality can be administered in just 20 minutes on SIGMA’s next-generation assessment platform. Scoring is automatic and reports are generated immediately. No need to spend time programming or scoring the assessment!

Data Quality – Whether you are conducting research, complementing coaching or counseling with personality insights, or identifying traits relevant to work performance, using high-quality data is essential. SIGMA Personality makes it easier to identify low-quality data with built-in checks for careless responding and impression management (social desirability).

Comprehensive Factor Coverage – SIGMA Personality expands upon the Personality Research Form (PRF), the Jackson Personality Inventory – Revised (JPI-R), and the Five-Factor Model in two important ways

• First, SIGMA Personality organizes facets of Conscientiousness into two distinct higher-order factors: Industriousness and Methodicalness. Measuring these factors separately permits a deeper understanding of an individual’s conscientiousness, which has been described as “the most potent, non-cognitive predictor of workplace performance”, and has been linked to several important life outcomes, including job performance and academic achievement.
• Second, SIGMA Personality also measures facets of Honesty/Humility, an important predictor of prosocial behavior, counterproductive workplace behaviors (CWBs), and the group of socially aversive traits known as the Dark Triad (narcissism, Machiavellianism, and psychopathy).
