Bespoke Personality Tests

We will work with you to design the most suitable work styles tool to suit your needs. Examples of the typical personality test format can be found here.

Our Bespoke Personality Questionnaire design process aims to:

  • include dimensions identified as key to the role being assessed
  • reflect the personality, attitudinal and motivational aspects of the role-specific dimensions
  • have face valid questions
  • be capable of completion in 20 minutes approx.
  • adopt a single-stimulus question format (Likert scale)
  • adopt a normative format of scoring utilising a sten look-up table (for each personality scale)
  • use a Social Desirability scale to deal with the issue of faking or extreme scoring patterns.

Key personality test design stages

The ideal for personality questionnaire design is to have sets of items on each  scale measuring the same latent variable – as described by the scale name and the scale descriptors. This is what is meant by the internal reliability of a personality questionnaire’s set of scales.

General Personality test Designs

We are not aligned with a particular test publisher. Thus, we can offer an independent perspective on any personality questionnaire design. Whilst we recommend designing bespoke personality tests, we can also advise on the most commonly used, off-the-shelf personality tests. These are listed below: firstly as general personality questionnaires; and then as personality questionnaires with specific applications.

  • SHL’s Occupational Personality Questionnaire (the 32-scale OPQ).
  • Kenexa’s OPI.
  • OPP’s 16PF5 Personality Questionnaire, MBTI Step I, MBTI Step II and the California Personality Inventory.
  • Saville Consulting’s Wave Styles.
  • Talent Q’s Dimensions.

Personality Values Test Design

We can design values assessment exercises design to focus on any values framework.

Values based recruitment may involve values based structured interviews, values based selection centres, values based situational judgement tests and/or values based personality tests.

Values based personality tests

Personality tests can be designed to measure values – as well as job specific constructs or competencies. As with a situational judgement based design, values based personality tests can serve as a highly effective realistic job preview, or self-selection tool.

If it is important to differentiate personality traits from values, then values can be seen as enduring goals, whilst personality better describes enduring dispositions.

Whenever a values based personality test is being used as part of a values based recruitment process, its vital to remember that personality influences motivational processes differently to how values drive motivational behaviour. Values impact goal content whereas personality traits impact the efforts that individuals make towards their goals.

MBTI Personality Test Tips

This personality inventory is based on the psychological types described by Carl Jung and developed by Isabel Briggs Myers and her mother Katharine Briggs to make the theory accessible to people. The theory is that seemingly random variation in behavior is due to basic difference in individuals’ preferences for perception and judgement, resulting in 16 different personality types. The original MBTI® assessment has spawned an endless array of imitators and innovators who have developed new assessments based on the 16-type system.

Big Five Personality Test Tips

Otherwise known as the 5-Factor Model, this assessment groups various traits together into five main categories – extraversion, conscientiousness, agreeableness, neuroticism and openness to experience. The Big Five is the most widely accepted personality model in the academic community and the basis for most personality research, but it is less popular outside of academic circles because it does not categorize people into easily summarized types. There is no one “official” Big Five test, but many researchers have developed their own assessments based on this theory.

DISC Personality Test Tips

The DISC personality profile was designed to measure behavioral styles and describes people in terms of their levels of dominance, influence, steadiness, and compliance. Assessments based on the DISC model are used widely in organizations to develop leadership skills, management training and team building. Free DISC tests are less common, as this model hasn’t gotten much attention outside of the business world.

Enneagram Personality Test Tips

The Enneagram began with a spiritual practice, not a scientific one, and conceptualizes personality as a dynamic system driven by emotions, fears, and beliefs. Traditionally, Enneagram knowledge was passed on by spiritual teachers, rather than formalized in an assessment. Recently, though, the system has become more popular, leading to the development of several assessments that aim to determine your Enneagram type.

How have psychometric tests evolved over the years?

  • The basic principles of test development did not change significantly until around 2010. In the previous decade, ability and personality tests have evolved considerably in terms of the uses to which they are put; and in what specific assessments can measure.
  • Development of ability tests that are based on structured learning principles
  • Adaptive tests and integrity tests are already widely used in the American educational system.

Specific Personality Assessment Designs

  • Hogan Development Survey (de-railers)
  • Kenexa and SHL’s Motivation Questionnaires
  • FIRO-B (relationship building)
  • MBTI for Teams (team relationships) and MBTI for Coaching
  • EJI and EIQ (emotional intelligence measures)
  • Thomas-Kilmann Conflict Mode (conflict management)
  • SHL’s Corporate Culture Questionnaire and Customer Contact Styles Questionnaire

Work Personality Tests Examples

In our opinion, the typical stages of such a personality questionnaire design project should be:

Firstly, investigate the job role(s) using the most appropriate types of job analysis.

Secondly, study the job analysis results to determine the personality areas or competencies that measure effective work performance within this particular context.

Thirdly, you have what you need to write questions for each personality area or competency.

Thus, you are able to produce a trial personality questionnaire and deliver this to a representative sample of current employees in the role(s).

Now, you can determine the best way to validate the questionnaire: (a) For example, using performance data such as sales figures, or appraisal ratings. (b) Designing a performance rating form for completion by managers of the sample group.

Next, produce scoring keys for the personality questionnaire scales.

Then, trial the personality questionnaire alongside the performance rating form.

Next, analyse the trial data and validation data to determine the personality scales and specific questions that are most predictive of work performance.

Finally, produce the final questionnaire, norm tables and scoring key.

Personality Test Distortion 

Social desirability scales 

You will probably not be able to fake this personality profile throughout the whole of the test. Your responses could easily be identified by the faking / social desirability scale used by the personality assessment tool. Then you could be asked to explain your “unusual” test taking style by one of the recruiters and/or be asked to take the personality assessment again.

Lie scales

Given the high potential for faking a personality test there are multiple ways built-in to test how reliable a candidate’s responses are. One of the most effective ways is what’s called a social desirability, or lie-scale.

For example, a personality test question may ask you to rate statements such as I have never told a lie or I have never been late for an appointment. Be wary of trying to come across as a perfect angel here. Everyone has told a lie at least once and everyone has been late at least some of the time.

Social Desirability – Personality scale Interpretation

A sten score of 8, 9 or 10 should be treated with caution and the respondent questioned accordingly at the interview stage – to validate their personality profile. The key point being that an extreme Social Desirability score indicates the respondent may be trying to distort their results by answering in an overly positive manner. As with any personality scale individuals have different social desirable tendencies so it’s difficult to distinguish genuine responses (for such positive attributes) from respondents intentionally distorting their answers.

A high Social Desirability score could reflect preferred behavioural style. In our opinion, it does not prove the respondent is lying / faking. This reinforces the need to validate any personality test profile with a follow-up interview. Then, to probe for interview evidence of such positive attributes.

Using Social Desirability as a personality scale

In our opinion, I have never told a lie, is one good example. Everyone has lied at some point. So, denying this is to answer in a socially desirable way. In fact, in our opinion, “Social desirability” describes two things:

  1. The tendency to exaggerate positive behaviours when answering a personality questionnaire. There is a tendency for a small percentage of personality questionnaire respondents to agree with seemingly desirable questions.
  2.  It also describes the moderation of negative behaviours. In other words, to disagree with socially undesirable questions (Zickar & Gibby, 2006).

It is therefore best practise in popular personality questionnaire design to use a Social Desirability scale to address such faking issues.


There are many personality tests used in career guidance and selection. Some tests display the person personality profile along 16 to 20 different dimensions.

The most popular of these tests are:

  • California Personality Inventory (CPI)
  • Cattell’s 16 Personality Factors (16PF)
  • Edward’s Personal Preferences Schedule (EPPS).

The advantage of these tests is that there are very comprehensive. Each was validated on the basis of enormous samples from a wide variety of occupations. This validity procedure established which occupations tend to score high on which dimensions.

So, sales representatives tend to score high on extroversion and dominance. Whereas chemists tend to be thinking introverts.

Personality Factors

A test like the 16PF has 20 factors (16 primary and 4 secondary). Using 20 personality factors, there are 110 possible combinations of two extreme scores (either high or low).

The MBTI is a very popular alternative to these tests. The MBTI:

  • Uses four basic bipolar dimensions.
  • Classifies the person into one of 16 possible personality descriptions.
