HPI (Hogan)

Generalities

HPI stands for Hogan Personality Inventory. The HPI was devised by Robert and Joyce Hogan to assess the FFM from the perspective of their socioanalytic model of personality. The authors say the model was built on research dating back to the 1970s. The HPI has been distributed by Hogan Assessment Systems, Tulsa, Oklahoma, USA, since 1987.

Other tests proposed by the Hogan Assessment System include the MVPI (Motives Values Preferences Inventory) and the HDS (Hogan Development Survey). The publisher proposes combining the three assessments into the HP-CAR, which stands for the High Potential Candidate Assessment Report.

The HPI was originally devised to answer questions about what a person’s reputation is as their most important attribute, and use personality measures to provide answers and make predictions about a person’s future behavior. It is presented as measuring the “normal” and “bright side” of personality.

Assessment

The HPI was originally a 310-item inventory of trait statements with six scales. It is based on Gough's CPI test, and other works such as the 16 PF, FFM, and the Big Five approach to personality. The HPI now comprises 206 True/False items. The test takes around 15 to 20 minutes to complete. Seven primary factors are measured (see below): Adjustment, Ambition, Sociability, Interpersonal Sensitivity, Prudence, Inquisitive, and Learning Approach. Each factor includes five facets, for a total of 41.

HCI additionally proposes comparisons with six occupational scales: Service Orientation, Stress Tolerance, Reliability, Clerical Potential, Sales Potential, and Managerial Potential. The HCI results are delivered in a variety of report formats, including suitability for the position, interview notes, and notes highlighting strengths. The seven primary factors measured by the HPI are the following:

Dimension	Description and Facets	GRI Correlation
Adjustment	Measures the degree to which a person appears calm, steady under pressure, and self-accepting, or conversely, open to feedback, candid, self-critical, moody, tense, and irritable.	Low3 versus high 3.
Ambition	Measures the degree to which a person seems socially self-confident, leader-like, restless, forceful, competitive, and energetic, or conversely good team player, complacent, unassertive, and less interested in leading and advancement.	High 1 versus low 1
Sociability	Measures the degree to which a person seems to need and/or enjoy interacting with others, is colorful, outgoing, talkative, seeks attention, or conversely is reserved, quiet, socially reactive, and prefers working independently.	High 2 versus low 2
Interpersonal Sensitivity	Measures the degree to which a person is seen as perceptive, tactful, friendly, warm, conflict-averse, and socially sensitive, or conversely is direct and frank, willing to confront others, cold and tough.	Low 1, high 2, high 3, high 4 versus High 1, low 2, low 3, low 4.
Prudence	Measures the degree to which a person seems conscientious, confirming, inflexible, and dependable, or conversely, is flexible, open-minded, and impulsive.	High 4 versus Low 4
Inquisitive	Measures the degree to which a person is perceived as bright, creative, imaginative, interested in intellectual matters, and a poor implementer, or conversely is practical, not easily bored, and un-inventive.	Low 1, low 2, high 3, low 4 versus high 1, high 2, low 3, high 4
Learning Approach	Measures the degree to which a person seems to enjoy academic and to value learning and educational achievement for its own sake, is insightful and may seem like a know-it-all, or conversely is a hands-on learner, focuses on their interest and is technology-averse.	Low 1, low 2, high 4 versus high 1, high 2, low4

Originally, the assessment was based on the factor extractions and correspondence established with the FFM (Five Factor Model): Adjustment corresponded to the Emotional stability dimension of the FFM; Ambition to the Extraversion dimension; Sociability to the Extraversion dimension as well; Interpersonal Sensitivity (originally called Likeability) to the Agreeableness dimension; Prudence to the Conscientiousness dimension; Inquisitive (originally called Intellectance) to Openness to Experience dimension; and Learning Approach (originally called School Success) to Openness to Experience dimension as well. The correspondence was established in 2003 based on the FFM factor loadings (from participants’ responses) and the content of the survey’s sample items.

Usage and Statistics

The HPI was initially sold only to psychologists (in 2006). It was primarily designed for use in personnel selection, individualized assessment, career-related decision-making, relationships, education, and research. This has evolved, and the HPI is more recently (2026) commonly sold to coaches for personal development, coaching, leadership development, and, to a lesser extent, for team dynamic exercises. The HPI survey includes reliability and numerous validity reports. It shows no adverse impact and meets EEOC requirements, which enables its use for recruitment. The publisher claims high test-retest reliabilities ranging from .69 to .87.

Comments

Theory

The HPI was developed within the context of socioanalytic theory, which posits that people are motivated to engage in social interaction by two universal motives: a need for social acceptance and a need for status. The technique explicitly states ift focuses on normal personality.

An actor's view and the observer's view of personality must be distinguished, and since one sees only an actor's behavior, assuming that survey respondents present themselves rather than report the truth, measurement efforts, according to HCI’s theory, should focus on reputation rather than what the person is like "down deep."

The theory continues by stating that profiles can be used to evaluate how others perceive a person, with important consequences for social acceptance and career success. They help experts build a better understanding of a candidate or employee and diagnose a situation. In contrast, GRI’s theory was driven by individual and organizational performance. For GRI, when relevant, a reputation’s measure is based on characteristics beyond those that instruments like HPI or GRI can capture.

Both systems focus on the normal and “bright side” of personality, as Hogan puts it, rather than the clinical side. Although the two systems share common ground on the basic structure of social behavior, HPI and GRI theories take vastly different approaches to addressing individual and organizational challenges. GRI brings refinements to the scales, takes the environment into consideration, and measures adaptation and engagement from a behavioral, emotional, and cognitive standpoint in ways that HPI can’t. Those aspects are built by GRI into a symbolic language learned and used in operations and by experts.

Forced or Free

HPI uses a forced-choice questionnaire that includes 206 True/False sentences, scored on a 10-point scale, and takes about 30 to 1 hour to complete. The GRI survey's open-ended free-choice scenario strategy differs vastly from HPI. It asks only two questions and proposes adjectives to check, based on whether they are part of the participant’s experience. It usually takes around 10 minutes to answer.

In both cases, statistics are applied to the answers, helping to relate results to a larger population and understand how the dimensions compare with each other. In the case of GRI, however, one of the survey questions is about the participant's experience of their environment, which is closer to a 360-degree approach than only a self-assessment.

Intensity

Hogan recognizes the low and high ends of the HPI scale, although each is labeled in favor of one side, and is broken down into four to eight subscales, for a total of 42 subscales, as trait systems typically do to bring more granularity. Ultimately, HCI is used as a trait system. The scales are measured in percentile scores that indicate where a person stands in relation to a large norm group of the general working population. The percentiles are organized into four broad categories for interpretation: Low (0 to 25th percentile), Below Average (26th to 50th percentile), Above Average (51st to 75th percentile), and High (76th to 100th percentile).

In contrast, GRI’s scales are in standard deviations, which provide a more accurate measure of a behavior’s occurrence, its intensity, and the emotions and cognitions that accompany it. The granularity and precision for describing social behavior come from analyzing the four factors together and their relative positions, which the standard scale makes possible. Additional granularity comes from analyzing adaptation, engagement, and response levels in the environment, which, again, are enabled by the standard deviation scales.

Orthogonality

The four dimensions Ambition, Sociability, Adjustment, and Prudence are close to GRI factors, respectively, 1, 2, 3, and 4 in that order, for common origins in the Five Factor Model, and the focus on social behavior. Those four factors are as orthogonal, independent, and complementary as they can be to cover social behaviors broadly. However, as already mentioned above, by assigning one label to each factor, HPI favors one side of the factor’s continuum over both, a common challenge shared with systems measuring traits.

The three other dimensions, Interpersonal Sensitivity, Inquisitive and Learning Approach, as indicated in the above table, combine the first four factors. Although appropriate for research, for practicality, these two dimensions, if relevant, may be assessed more effectively by other techniques, such as semi-directive interviews, biodata, or social media scans, rather than self-report questionnaires.

Adaptation

The HPI model does not account for behaviors that people feel compelled to adapt to their environment. HPI’s measurement combines natural and adaptive behaviors into a single metric. In the HPI model, a person’s natural self is influenced by their perceived adaptation, which only reflects how they see themselves at the moment they answer the survey.

How people adjust their behavior and how they are engaged are key pieces of information that connect individuals to their environment and job demands, yet the HPI model does not include these elements.

Work relatedness

The HPI uses the Job Evaluation Tool (JET) and its four components, particularly the Performance Improvement Characteristic (PIC), to complete a job analysis. The PIC contains 48 items that the publisher says conceptually and empirically align with the HPI, but nevertheless cannot establish a one-to-one correspondence. In comparison, the GRI uses techniques such as the PBI (Position Behavior Indicator) and the TBI (Team Behavior Indicator) to define the behaviors expected in jobs and teams, with the same four factors and profiles, thereby enabling the analysis of fit with individual results, the need for adaptation, and how that adaptation will happen.

Representation Model

HPI results come with reports, as all systems do; The measures are represented as bar charts that show the percentile scale and where the measure stands, as personality traits typically do. In contrast, GRI presents the measures with adaptive profiles and using standard deviation scales, which more accurately help concentrate, compare, learn, and use the measured information.

General validity

A general comment applies here to people who receive their HPI results: they typically accept information from reports and feedback sessions. This is unsurprising because the survey responses reflect what people know about themselves.

In comparison, nuances from a GRI feedback session arise not only from the nature of the dimensions being measured but also from the scales used to measure them and how the dimensions relate to one another. Commenting on the context, adaptation, engagement, and response levels provide additional indications for development and adjustments.

Learning

HPI learning typically focuses on the dimensions measured and on the applications of these measures for personal, recruitment, and organizational development. Since the HPI scales don’t capture a person’s adaptation, engagement, and other essential characteristics that connect a person to their environment and affect their motivation and relationships with others, the learning can only have a slight impact on a modus operandi for long term personal and organizational development. In contrast, GRI is learned as a tool for analyzing people and organizations, providing new insights that may initially seem counterintuitive but ultimately help develop more realistic, effective solutions, starting from the outset of the learning process.
