The Big Five Aspects Scale (BFAS) is a model based on the Big Five, that is used to describe and measure human personality traits. This five factor model is broken down into two facets per factor. Namely, the BFAS extends these five factors by breaking them down into smaller, more specific facets: Openness to experience: how open-minded, imaginative, and creative you are, broken down into Intellectual curiosity and Openness. Conscientiousness: how organized, responsible, and dependable you are, broken down into Industriousness and Orderliness. Extraversion: how outgoing, energetic, and assertive you are, broken down into Enthusiasm and Assertiveness. Agreeableness: how cooperative and compassionate you are, broken down into Compassion and Politeness Neuroticism: how you experience emotions, broken down into Volatility and Withdrawal. The BFAS is often used in research to measure and study personality traits.

        Frequently asked questions

        What is the big five model of personality?

        For centuries, people have been intrigued by the differences in personalities and have attempted to understand and measure them. Despite the belief that body and soul are separate entities, people have searched for physiological connections to explain the psychological differences between them. With the advent of computational methods in the 20th century, scientists discovered a new approach to measuring differences between individuals based on everyday language used to describe them. This led to the creation of the Big Five or OCEAN theory. The theory and the test based on it were developed by collecting a long list of adjectives commonly used to describe others and analyzing which words frequently appear together. This method allowed psychologists to develop a comprehensive description of an individual's personality based on five basic aspects. These aspects are Openness to experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (also known as Emotional Stability).

        Why is the big five aspects scale test reliable?

        The BFAS personality test is a reliable and effective tool for assessing personality traits. Its rigorous scientific development, cross-cultural and cross-linguistic validity, comprehensive model of personality, and self-report nature all contribute to its high degree of reliability, making it a valuable resource for gaining insights into an individual's personality.
        The Big Five test was carefully crafted using a large sample size of individuals from diverse backgrounds, and the results were analyzed using advanced statistical methods to ensure that the test was measuring what it intended to measure. The Big Five is considered reliable because it has consistently demonstrated high levels of validity and reliability across various cultures and languages. The test has been utilized in numerous studies and has consistently produced consistent and meaningful results, further solidifying its credibility. Also, it is based on a comprehensive model of personality that has been meticulously developed and refined over many years. This model has undergone extensive research and validation, and its five broad dimensions of personality have been found to be stable and enduring over time. Another factor contributing to the Big Five's reliability is its self-report nature. Rather than being evaluated by an outside source, individuals are asked to describe themselves, which helps reduce the potential for bias and ensures that the test results are based on the individual's own self-perception.
        Jordan Peterson, Colin DeYoung, Lean Quilty and Jeremy Gray have conducted extensive research on the Big Five Aspects Scale (BFAS) and its applications in various fields. Their research has focused on the development and validation of the BFAS, its use in understanding personality traits and their impact on behavior, cognition and well-being. They have also explored the relationship between the BFAS and other psychological constructs, such as intelligence, creativity, and psychopathology. One of their key findings is that the BFAS is a reliable and valid measure of personality traits, with strong correlations between the five broad dimensions and their associated facets. They have also found that the BFAS can be used to predict a wide range of behaviors, from academic achievement to job performance to health outcomes. Additionally, Peterson, DeYoung, and their colleagues have explored the potential applications of the BFAS in various fields, including education, business, and clinical psychology. They have suggested that understanding personality traits can help individuals and organizations make better decisions, improve communication and teamwork, and promote personal and professional growth.

        Who created the big five personality test?

        The Big Five was created over several decades by a team of researchers in the field of psychology. One of the earliest contributors to the development of the Big Five was the psychologist Raymond Cattell, who in the 1940s proposed a theory of personality that included 16 different factors. This theory was later refined and expanded upon by other researchers, leading to the creation of the Big Five. The final version of the Big Five personality test was developed in the 1980s by two psychologists, Lewis Goldberg and Warren Norman. They identified the five broad dimensions of personality that are still used today: Openness to experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.

        Who created the Big Five Aspects Scale model?

        The Big Five Aspects Scale (BFAS) was developed by Dr. Colin DeYoung and other researchers. It is based on the Five Factor Model of personality and extends it by breaking the factors down into smaller facets. The development of the BFAS involved theoretical analysis, factor analysis, and extensive research, resulting in a comprehensive and reliable model of personality. If you’re wondering how to cite the big five aspects scale, then there are numerous research papers on the Big Five Aspects Scale.
        The key influential paper is "The Big Five Trait Taxonomy: History, Measurement, and Theoretical Perspectives," by Lewis R. Goldberg. It provides a comprehensive overview of the development of the Big Five personality traits, and their underlying facets, including the BFAS.
        A second key paper is "The Development and Validation of the Big Five Aspect Scales," by Colin G. DeYoung, Lena C. Quilty, and Jordan B. Peterson. This paper describes the development and validation of the BFAS, including its reliability and validity across different cultures and languages.
        A third notable paper is "The Role of Personality Traits in Predicting Earnings," by James J. Heckman, Jora Stixrud, and Sergio Urzua. It uses the BFAS to explore the relationship between personality traits and earnings, finding that traits such as conscientiousness are positively associated with higher earnings.
        Other key research papers on the BFAS include "The Validity of the Big Five Aspects Scale for Children and Adolescents," by Kali H. Trzesniewski, M. Brent Donnellan, and Richard W. Robins, and "The Big Five Personality Dimensions and Job Performance: A Meta-Analysis," by Timothy A. Judge and colleagues.
