Which model includes the traits of openness, conscientiousness, extraversion, agreeableness, and neuroticism?

The model that includes the traits of openness, conscientiousness, extraversion, agreeableness, and neuroticism is known as the Big Five model. This framework is widely recognized in psychology for describing the fundamental dimensions of human personality. Each of these traits represents a broad spectrum of behaviors and attitudes; for instance, openness reflects creativity and curiosity, conscientiousness pertains to organization and dependability, extraversion relates to sociability and assertiveness, agreeableness refers to compassion and cooperation, and neuroticism encompasses emotional instability and anxiety.

The Big Five model has been supported by extensive research and is often used in both academic settings and practical applications, such as personality assessments. Other models, like trait theory, include a variety of approaches to personality, but the Big Five specifically delineates these five core traits that are essential for understanding personality structure. The HEXACO model also includes traits, but it adds honesty-humility as a sixth dimension, distinguishing it from the Big Five. Types theory, on the other hand, focuses on categorizing people into distinct personality types, which differs from the trait-based approach of the Big Five. Thus, the emphasis on these five traits makes the Big Five model the correct answer.
