This frame and its counterpart, Character Trait: Negative, are similar to the Mental Property frame in that they involve a (usually implicit) Judge who determines that some Protagonist possesses a particular character trait, based on the their Behavior. The primary difference is that here, the basis of the judgement is Behavior toward other human beings (the Company). This gives the Character Trait frames a definitive social component.

The Character Trait: Positive frame contains lexical units that denote positive (and a few neutral) character traits such as "nett" ("nice"), "freundlich" ("friendly") or "schüchtern" ("shy"). The related frame, Character Trait: Negative, contains lexical units that denote negatively judged character traits, such as "unhöflich" ("impolite") or "gemein" ("mean").

The Company in this frame is often affected in some way by the Behavior of the Protagonist, and it is possible to mention both the Company and the degree to which the Protagonist behaves appropriately toward them. Alternatively, the Behavior may be expressed alone, with the understanding that these behaviors characterize a property of the unmentioned Protagonist. Furthermore, the Protagonist's Behavior may be mentioned with relation to some Content, which is the relevant context of the Behavior (typically a set of circumstances that elicited the Behavior).
