Jackson Personality Inventory™-Revised

The Jackson Personality Inventory™-Revised (JPI™-R) is an online personality assessment designed to evaluate normal adult personality traits and predict an individual’s behavior across interpersonal, educational, and professional settings. The test consists of 300 true/false questions, takes approximately 45 minutes to complete, and instantly generates a comprehensive report. Built using sophisticated test development methods, it includes built-in safeguards to filter out random answers or candidates trying to guess what “sounds good” rather than answering honestly.

What is the Jackson Personality Inventory™-Revised?

The JPI-R is a revision of the original JPI. Like its predecessor, the JPI-R assesses personality variables relevant to the functioning of a person in a wide range of settings such as those involving work, educational/organizational behavior, or interpersonal situations. The JPI-R contains a total of 300 True/False items and takes about 45 minutes to administer. Revisions to the original JPI materials include (a) updated college norms, (b) entirely new norms for blue and white collar workers, (c) renaming of some scales to better reflect scale content, (d) scale organization in terms of five higher-order dimensions, (e) removal of the Infrequency scale to facilitate use for employment screening, (f) coverage of extended distributional characteristics, (g) compilation of new research findings, (h) addition of scale-by-scale item lists to promote scale interpretation, (i) a glossary of technical terms to facilitate understanding of the often sophisticated procedures used in constructing the JPI and JPI-R, and (j) a new quick-scoring answer sheet, which eliminates the need for a separate scoring template. The JPI-R’s 15 scales are as follows, organized in terms of five higher-order clusters:

• Analytical: Complexity, Breadth of Interest, Innovation, Tolerance
• Extroverted: Sociability, Social Confidence, Energy Level
• Emotional: Empathy, Anxiety, Cooperativeness
• Opportunistic: Social Astuteness, Risk Taking
• Dependable: Organization, Traditional Values, Responsibility

The statistical procedures employed in the construction of the JPI are among the most elaborate ever employed for a personality test. Starting with a very large item pool, two separate item analyses on separate samples were undertaken to further three general aims: (a) to maximize item content saturation in relation to desirability variance; (b) to maximize scale reliabilities; and (c) to minimize interscale redundancy.

What It’s Best Used For

• Personnel selection and hiring: Assisting psychologists and hiring teams in evaluating whether an applicant’s core behavioral traits align with specific job demands.
• Corporate team-building: Mapping out the collective strengths of a department to foster better communication, collaboration, and cooperative work dynamics.
• Managerial and career counseling: Helping coaches guide employees or leadership candidates toward greater self-awareness, personal motivation, and tailored professional growth paths.
• Measuring precise personality clusters: Evaluating individuals across 5 core clusters and 15 distinct scales, including Analytical traits (innovation, complexity), Extroversion (social confidence), Emotion (empathy, anxiety), Opportunism (risk-taking), and Dependability (responsibility, organization).
• Academic and behavioral research: Providing data for psychological or organizational studies requiring highly reliable, sensitive, and valid data points on human functioning.

Who Should Use the Jackson Personality Inventory™-Revised?

• Counselors seeking to examine clients’ personality trait information at both the cluster or individual scale level
• Psychologists looking for detailed trait information to include in a selection battery
• Users seeking convenient online administration and a comprehensive, easy to interpret report
• Research on personality in a variety of settings

Why Should I Use the Jackson Personality Inventory™-Revised?

CONVENIENT

The JPI-R can be administered in 45 minutes online.  Reports are generated immediately.  Results are presented using graphs, numbers, and scale descriptions.

ELABORATE TEST CONSTRUCTION

A large item pool and extensive item analyses have helped create a superior assessment that is highly reliable and sensitive to response bias. In particular, the items selected correlate minimally with desirability–the tendency to answer in a way that “sounds good”, rather than answering honestly. The JPI-R also has special features that help detect random, or non-purposeful responding. Test norms are based on the responses of 1107 North American individuals.

RELIABLE AND VALID

The JPI-R is a reliable and valid measure of personality. Hundreds of correlations of JPI scales with a variety of criteria, ranging from occupational preferences to executive performance, are reported in the manual.

Scales Measured

5 CLUSTER SCORES AND 15 SCALE SCORES

Analytical

• Complexity
• Breadth of Interest
• Innovation
• Tolerance

Extroverted

• Sociability
• Social Confidence
• Energy Level

Emotional

• Empathy
• Anxiety
• Cooperativeness

Opportunistic

• Risk Taking
• Social Astuteness

Dependable

• Organization
• Traditional Values
• Responsibility

Reliability and Validity

The items on the JPI-R are the same as those included in the original JPI (with minor exceptions in the case of the Traditional Values scale). Accordingly, findings bearing on the JPI’s psychometric properties are applicable to the JPI-R. In two studies, median internal consistency reliabilities (Bentler’s Theta) were .90 and .93. Data on JPI validity include analyses of two multitrait-multi-method matrices employing adjective checklist, self rating, and peer ratings. Hundreds of correlations of JPI scales with a variety of criteria, ranging from occupational preferences to attitudes toward marijuana use, are reported in the manual.
