In Christian tradition, there are said to be "seven deadly sins": Lust, Gluttony, Greed, Sloth, Wrath, Envy, and Pride.
In Catholicism specifically, there are sometimes said to be seven virtues, each sin having an opposite: Chastity, Temperance, Charity, Diligence, Patience, Kindness, and Humility.
In a sense, this is a personality model. (Each sin/virtue duality can be thought of as a spectrum, with the sin lying at one end, and the virtue at the other. In the middle would be the "average" soul.)
In psychology, the "Big Five" traits come to mind, with the acronym "OCEAN": Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.
