The Jackson Personality Inventory™-3 (JPI™-3) (formerly known as the SIGMA Personality) is the evolution of two foundational personality assessments, the Personality Research Form (PRF) and the Jackson Personality Inventory – Revised (JPI-R).  With more than 4,500 references combined, these personality assessments are among the most cited in scientific literature, attesting to their impact and credibility.  The JPI-3 builds on the legacy of these assessments, the Five-Factor Model, and personality research to deliver a comprehensive measure of personality in just 20 minutes.

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.  The Jackson Personality Inventory™-3 was 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.

What Does Jackson Personality Inventory™-3 Measure?

Jackson Personality Inventory™-3 measures 42 distinct traits grouped into seven personality dimensions: Agreeableness, Emotional Stability, Extraversion, Honesty/Humility, Industriousness, Methodicalness, and Openness to Experience. Each dimension covers a different broad area of personality.

What Makes the JPI-3 Better?

The JPI-3 goes beyond traditional tools like the Five-Factor Model. It gives a clearer picture of traits that matter most at work, including deeper insights into Conscientiousness and Honesty/Humility.

Twice the insights on factors that predict performance: The JPI-3 separates Conscientiousness into two distinct traits: Industriousness (drive and work ethic) and Methodicalness (organization and attention to detail). This split gives a more accurate view of how an individual will perform on-the-job, because conscientiousness has been found to be a strong predictor of both workplace performance and academic achievement.

Key indicators for prosocial and antisocial behavior: The JPI-3 measures Honesty/Humility in addition to the traditional Five-Factor traits. Honesty/Humility helps predict prosocial behavior as well as counterproductive workplace behaviors and toxic traits like narcissism, machiavellianism, and psychopathy — key insights for building strong, reliable teams.

Why Choose Jackson Personality Inventory™-3?

Convenience – Jackson Personality Inventory™-3 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. Jackson Personality Inventory™-3 makes it easier to identify low-quality data with built-in checks for careless responding and impression management (social desirability).

Comprehensive Factor Coverage – Jackson Personality Inventory™-3 expands upon the Personality Research Form (PRF), the Jackson Personality Inventory – Revised (JPI-R), and the Five-Factor Model in two important ways

• First, Jackson Personality Inventory™-3 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, Jackson Personality Inventory™-3 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).
