Measures a person's overall attitude toward an informative communication source — such as an article, book, TV news program, or website — with an emphasis on its usefulness and credibility. The scale blends evaluative, credibility, and utility dimensions into a single composite measure. Originally used as a pretest check to ensure article stimuli were perceived as credible and useful before use in experiments on brand self-efficacy effects.
