Personality Test Design

Rob Williams Assessment Ltd have considerable experience in assessing the validity of psychometric tests. This is a one of the key final stages in any psychometric test design. In addition to test the SJT reliability and to advise on suitable cut-off scores which minimise any adverse impact (due to gender, age, ethnic group and disability).

Many of the UK’s and US’s leading test publishers have used Rob Williams Assessment’s to assist with ensuring the psychometric properties of their trial psychometric tests. We consult on how to improve any test’s psychometric properties, particularly the test’s internal reliability and construct validity.

Personality test trends

Candidates may also have to take a personality test as part of the recruitment process. There is a vast array of personality tests, which pose questions about a candidate’s behaviour and personal preferences. A typical question may ask whether you prefer attending parties or staying home with a good book. These personality tests help employers to determine whether a candidate has the right profile for the role.

Biodata questions

Personality biodata questions measure a variety of constructs, including attitudes, personality attributes, interests, skills/abilities, past events and experiences. An individual’s learning history is of particular interest.

Which personality traits do employers look for?

Sackett and Walmsley used a well-established model for measuring personality known as the Big Five as the theoretical basis for their study. In the Big Five model, an individual’s personality can be described using measures of five personality traits: conscientiousness, agreeableness, emotional stability, extraversion, and openness to experience.

The researchers analyzed a large set of data on job interviews to find out which personality traits companies look for when they’re hiring. Much of the data came from an analysis of structured job interviews, in which employers assess candidates for particular personality traits in order to make sure they’re a good fit for the job and overall work environment. For example, a company that is hiring a salesperson would want to assess job candidates for the traits of extraversion and friendliness to make sure they’re likely to work well with customers.

After crunching the numbers, Sackett and Walmsley found that conscientiousness was by far the most highly sought after personality attribute for job applicants. Agreeableness–being cooperative, flexible and tolerant–was the second most prized personality trait.

The researchers also analyzed data indicating the specific skills and qualities needed to be successful at over a thousand different jobs, drawn from a Department of Labor database called O*NET. They wanted to find out which of the Big Five personality traits are most often cited as important qualities for success across the entire American workforce.

The researchers found that overall attributes related to conscientiousness, agreeableness, and emotional stability were considered important for a wide variety of jobs from construction to health care.

Personality type career guidance

We all know one person who loves the job. Another who just hates upper management politics. another who doesn’t want to deal with people.

Can you get promoted in a way that keeps you using your personality authentically. Unfortunately, to be successful you have to understand firstly your personality type. Secondly, the way it will interact with the people around you.

Personality type career mismatches

Your personality type certainly affects the way you think and act. Plus, other people’s perceptions of you.

This isn’t a complicated idea, but it is a critical one. Your personality type and any misperceptions others have about it are likely to self perpetuate and drive your career. It’s a feedback loop, regardless of whether or not it’s positive or negative; if you’re unhappy with your job and others know it, you’re likely to become more unhappy about your job. If your personality type doesn’t fit your job, you’re likely to be unhappy there.

Personality type career guidance

Career success requires finding a job that matches your personality traits. The idea becomes doubly true once you start moving up the ladder. This is why you can guess what department somebody is from just by their attitude toward the company.  So before you accept a personality-type based promotion, you need to know what jobs you can and can’t do.

3) Focus groups

Thirdly, semi-structured focus group format represented the most suitable job analysis technique to use.

4) Role survey

Fourthly, a role survey based on the bank’s competency framework, with two questions per competency. Survey results informed the item writing process. The final 5-10 minute survey had two banks of questions with the stems:

  • How important do you do each of the following on a daily basis?
  • How important are the following to your job?

Candidate Experience Briefing

A separate briefing detailed the client style and language (US English) needs. The main aims from a “Candidate Experience” perspectives included:

  • Reflecting the company brand
  • Engaging job applicants
  • Providing some elements of a realistic job preview
  • Overall look and feel to be consistent

Focus Group Briefing

Firstly, focuses on how best to structure the upcoming focus group sessions. Secondly, a consideration of the outputs required. Thirdly, how individual consultants could best run their focus group sessions. The focus group aims were to confirm the role profile interview data; engender key stakeholder support for the blended assessment project (and any associated changes that the new tests required); and to complete a few final visionary interviews.

  • 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

Work Personality Assessment Designs – internal reliability

There are many ways to statistically measure the internal reliability of each scale on a personality questionnaire. Probably the most common is Chronbach Alpha. The advantage of using this measure of a personality test’s internal reliability is the agreement in the literature of what represents an acceptable Chronbach’s Alpha score for any personality questionnaire scale. A score above .7 indicates an internally reliable scale.

WORK PERSONALITY ASSESSMENT FAKING

One of the commonest criticisms of personality tests has been their fakeability. All personality assessment output relates to the candidate’s own answers and any pertinent points can be discussed at interview.

Test developers can build-in strategies to make faking more difficult, such as using different types of social desirability scale. Giving a consistently false picture is more difficult with a robust personality questionnaire. It also assumes that the candidate knows enough about the interviewer and their prospective employer to be able to guess at the ‘correct’ personality profile. A lengthy completion time may also indicate that a candidate has crafted their answers around what they consider to be a ‘correct’ personality profile.

WORK PERSONALITY ASSESSMENT EXAMPLE – THE MBTI

The MBTI® personality type instrument indicates an individual’s preferred behavioral styles. In particualr for interacting, using information and making decisions. It does not provide any indication of ability or suitability for a role. People of all types can do anything. However their natural tendency or first instinct may be to act in a certain manner.

There is research to suggest that people of certain types may find some professions more attractive. However there is no research to suggest that they will perform better than people of other types.
