Background & Theory
In the late 1950s and early 1960s, Dr. Thomas Hendrickson developed William Moulton Marston’s DISC theory to produce the Thomas Personal Profile Analysis (PPA) for the work place.
Marston’s original theory viewed people behaving along two axes, with their attention being either passive or active, depending on the individual’s perception of their environment as either favourable or antagonistic. It was theorised that the way in which the individual interacts takes four basic directions: tendencies to dominate, influence, submit and comply.
The Thomas PPA describes 4 adapted behavioural factors. Each factor is seen as a scale of preference of style as perceived by an individual of his or her own behaviour in the workplace. The factors arise from different human needs, which result in habitual patterns of creating a characteristic “style”. These 4 factors are: Dominance, Influence, Steadiness and Compliance.

Format of the Thomas PPA test
When doing PPA testing, individuals are asked to choose 2 trait adjectives from a list of 4, one ‘most like’ and one ‘least like’ them. This process is repeated 24 times, giving 48 choices from a total of 96 words. An individual’s response patterns are then compared to themselves rather than the scores of a comparison group.
Thomas have also developed the PPA+ format which is suitable for people with a reading age of 11+ and for candidates who are fluent in English but for whom English is not their first language.

Reliability & Validity
The Thomas PPA has been subject to rigorous scientific testing to determine its reliability and validity as a psychological assessment. The PPA is registered with the British Psychological Society (BPS) after it was audited against the technical criteria established by the European Standing Committee on Tests and Testing, part of the European Federation of Psychologists' Associations.

Frequently Asked Questions
Thomas’ Personality Profile Analysis (PPA) is a personality test which enables employers to evaluate a candidates’ character traits in a more in-depth way to determine whether they will be a suitable fit for a role as well as how they prefer to communicate with others.
The Thomas PPA is a forced-choice questionnaire where candidates are shown short statements and are asked to choose two trait adjectives from a list of four, one ‘most like’ and one ‘least like’ them. An individual’s choice of adjectives reflects their behavioural tendencies and personality in a workplace setting.
From this, a personal profile is created around four traits: Dominance, Influence, Steadiness and Compliance. These traits are ranked in order to form one’s unique character. The Thomas PPA only takes 8 minutes to complete.
The PPA is based on Marston’s DISC theory which classifies an individual’s behavioural preferences and splits them into four factors: Dominance (D), Influence (I), Steadiness (S), and Compliance (C).
While most people will show all four of these behaviour patterns at times, an individual will display one or more of them consistently in the workplace. This is because each person develops a behavioural style which places more emphasis on one preference and less emphasis on others.
The PPA provides a comprehensive assessment of an individual including their fears, motivators, values and behavioural style. It gives you insights into how someone is likely to perform under pressure, how they modify their behaviour in their current job and any frustrations or problems they may be facing.
The PPA can also be used as a tool to back up your recruitment decisions and identify behaviours that were not shown at the interview stage. Since the PPA makes employers aware of their employee’s work styles, it also improves people management through a greater understanding of why people behave the way they do.
