Eysenck Personality Questionnaire
The Eysenck Personality Questionnaire (EPQ) is a widely used personality assessment tool that was developed by Hans Eysenck in the 1950s. The original EPQ was designed to measure three dimensions of personality: extraversion, neuroticism, and psychoticism. In recent years, a revised version of the EPQ has been developed which includes a fourth dimension, the lie scale, and questions related to social desirability.
The EPQ is administered through paper and pencil or online and takes approximately 20-30 minutes to complete. The results of the EPQ are used to understand an individual’s personality traits and how they compare to others in the same age and gender group. While the EPQ is a valuable tool for understanding personality, it is important to recognize its limitations and criticisms.
History of the EPQ
Hans Eysenck was a German-British psychologist who developed the EPQ as a tool to measure personality traits. He believed that personality could be understood through three dimensions: extraversion, neuroticism, and psychoticism. Extraversion referred to an individual’s level of sociability, assertiveness, and activity level. Neuroticism referred to an individual’s level of emotional stability and their tendency to experience negative emotions. Psychoticism referred to an individual’s level of aggression, impulsivity, and unconventionality.
The original EPQ consisted of 50 questions and was administered through paper and pencil. It was designed to measure these three dimensions of personality in order to understand individual differences and predict behavior. Eysenck believed that these dimensions were biologically based and could not be changed. The EPQ gained widespread popularity and has been used in various research studies and clinical settings.
In recent years, a revised version of the EPQ has been developed which includes a fourth dimension, the lie scale, and questions related to social desirability. The lie scale measures an individual’s tendency to present themselves in a more favorable light and avoid answering questions honestly. The inclusion of these additional questions allows for a more comprehensive understanding of an individual’s personality.
The Revised EPQ
The revised version of the EPQ includes a fourth dimension, the lie scale, and questions related to social desirability. The lie scale measures an individual’s tendency to present themselves in a more favorable light and avoid answering questions honestly. The inclusion of these additional questions allows for a more comprehensive understanding of an individual’s personality and helps to control for the potential influence of social desirability on the results.
The revised EPQ also includes updated questions and has a longer length compared to the original version. It consists of 90 questions and is administered through paper and pencil or online. It takes approximately 20-30 minutes to complete. The revised EPQ measures the four dimensions of personality: extraversion, neuroticism, psychoticism, and lie scale.
The revised EPQ is a valuable tool for understanding personality traits and differences. It provides a comprehensive assessment of an individual’s characteristics and can be used in various settings, including research studies and clinical settings. However, it is important to recognize the potential limitations and criticisms of the EPQ, such as the influence of social desirability on the results.
Dimensions of Personality
The Eysenck Personality Questionnaire (EPQ) measures four dimensions of personality: extraversion, neuroticism, psychoticism, and lie scale.
- Extraversion refers to an individual’s level of sociability, assertiveness, and activity level. People who score high on the extraversion dimension tend to be outgoing and energetic, while those who score low tend to be more introverted and reserved.
- Neuroticism refers to an individual’s level of emotional stability and their tendency to experience negative emotions. People who score high on the neuroticism dimension tend to be more anxious and prone to negative emotions, while those who score low tend to be more emotionally stable.
- Psychoticism refers to an individual’s level of aggression, impulsivity, and unconventionality. People who score high on the psychoticism dimension tend to be more aggressive and impulsive, while those who score low tend to be more conventional and controlled.
- The lie scale measures an individual’s tendency to present themselves in a more favorable light and avoid answering questions honestly. People who score high on the lie scale tend to be more likely to present themselves in a more positive light, while those who score low tend to be more honest and straightforward in their responses.
Administration and Scoring of EPQ
The Eysenck Personality Questionnaire (EPQ) is administered through paper and pencil or online and takes approximately 20-30 minutes to complete. It consists of 90 questions that measure the four dimensions of personality: extraversion, neuroticism, psychoticism, and lie scale.
The questions in the EPQ are designed to assess an individual’s personality traits and characteristics. They are written in a yes/no format and are designed to be easy to understand and answer.
To score the EPQ, the responses to the questions are totaled and compared to normative data for the individual’s age and gender group. Normative data is a statistical representation of the scores of a large group of people within a specific age and gender group. By comparing an individual’s scores to the normative data, it is possible to understand how their scores compare to others in their age and gender group.
The results of the EPQ provide an understanding of an individual’s personality traits and how they compare to others in the same age and gender group. The scores on each dimension are interpreted based on how they compare to the normative data. For example, someone who scores high on the extraversion dimension would be considered more extroverted compared to others in their age and gender group.
It is important to recognize that the EPQ is a tool to understand personality traits and differences, and should not be used to make definitive conclusions about an individual’s behavior or potential. It is also important to consider the potential limitations and criticisms of the EPQ, such as the influence of social desirability on the results.
Interpretation of Results
The results of the Eysenck Personality Questionnaire (EPQ) provide an understanding of an individual’s personality traits and how they compare to others in the same age and gender group. The scores on each dimension are interpreted based on how they compare to the normative data.
For example, someone who scores high on the extraversion dimension would be considered more extroverted compared to others in their age and gender group. Someone who scores high on the neuroticism dimension would be considered more anxious and prone to negative emotions compared to others in their age and gender group. Someone who scores high on the psychoticism dimension would be considered more aggressive and impulsive compared to others in their age and gender group. And someone who scores high on the lie scale would be considered more likely to present themselves in a more positive light compared to others in their age and gender group.
It is important to consider the potential limitations and criticisms of the EPQ when interpreting the results. The EPQ is a tool to understand personality traits and differences, and should not be used to make definitive conclusions about an individual’s behavior or potential. Additionally, the influence of social desirability on the results may affect the accuracy of the scores.
Overall, the results of the EPQ can be useful in understanding an individual’s personality traits and differences and can be used in various settings, including research studies and clinical settings. However, it is important to recognize the potential limitations and criticisms of the EPQ and use caution when interpreting the results.
Uses and Applications of EPQ

- Research studies: The EPQ is often used in research studies to understand personality traits and differences and their potential impact on behavior.
- Clinical settings: The EPQ is used in clinical settings, such as in therapy or counseling, to help understand an individual’s personality traits and how they may be impacting their behavior or mental health.
- Selection and recruitment: The EPQ is sometimes used in the selection and recruitment process for jobs or educational programs to assess an individual’s personality traits and determine their fit for a particular role.
- Personal development: Some individuals may choose to take the EPQ for personal development purposes, to better understand their own personality traits and how they may impact their relationships and interactions with others.
Overall, the EPQ is a valuable tool for understanding personality traits and differences and has various uses and applications in different settings. However, it is important to recognize the potential limitations and criticisms of the EPQ and use caution when interpreting the results.
Criticisms and Limitations
The Eysenck Personality Questionnaire (EPQ) is a widely used personality assessment tool that has various uses and applications. However, there are also criticisms and limitations of the EPQ that should be considered when interpreting the results.
One criticism of the EPQ is that it is based on the assumption that personality can be understood through three (or four) dimensions, which may not be comprehensive enough to accurately capture the complexity of personality. Additionally, some critics argue that the dimensions measured by the EPQ, such as extraversion and neuroticism, are culturally biased and may not be applicable to all populations.
Another limitation of the EPQ is the influence of social desirability on the results. The revised version of the EPQ includes a lie scale to measure an individual’s tendency to present themselves in a more favorable light, but it is still possible for individuals to intentionally or unintentionally provide responses that are not completely honest. This may affect the accuracy of the scores and should be considered when interpreting the results.
Overall, while the EPQ is a valuable tool for understanding personality traits and differences, it is important to recognize its limitations and criticisms and use caution when interpreting the results. It is also important to consider other factors, such as cultural background and social desirability, that may affect the accuracy of the scores.
Available Versions
There are two main versions of the Eysenck Personality Questionnaire (EPQ): the original version and the revised version.
The original version of the EPQ consists of 50 questions and measures three dimensions of personality: extraversion, neuroticism, and psychoticism.
The revised version of the EPQ consists of 90 questions and measures four dimensions of personality: extraversion, neuroticism, psychoticism, and lie scale. The revised version also includes questions related to social desirability.
