There are a few scales that measure the Big Five Personality Traits. One acronym is the word OCEAN. Each letter refers to the first letter of a Big Five personality trait.
Scientific studies by Paul Costa and Robert McCrae (1998) established a basis for the five factors known by the acronym OCEAN, which I refer to below.
See Big Five Personality Theory for more details and references.
O- Openness to experience includes curiosity, imagination, and creativity. People high in this trait appreciate complexity and originality and enjoy new experiences.
C- Conscientiousness describes behavior patterns of self-control and acting in socially acceptable ways. People high in conscientiousness are dependable, work within rules, plan and organize effectively, and have a strong degree of gratification.
E- Extroversion (aka extraversion) is often considered along with introversion. In a sense, the dimension identifies where a person finds their energy. Extroverts thrive in the presence of others while introverts need to withdraw from people to restore their souls in solitude.
A- Agreeableness refers to patterns of interactions with others and contrasts with disagreeableness. People might describe those high in agreeableness as altruistic, trusting, modest, humble, patient, tactful, polite, kind, loyal, helpful, sensitive, amiable, cheerful, and considerate.
N- Neuroticism refers to emotional stability. Sensitive clinicians reframe this term as Emotional Stability.
