Four brief unipolar items assess how acceptable, fitting, and proper a particular object or behaviour is perceived to be. Li, Chan, and Kim (2019) used the scale in Study 3 with 509 MTurk participants to evaluate the appropriateness of a service employee using emoticons in chat messages. The source of the scale was not identified. The items are sufficiently general to be applied across a broad range of contexts.
