The impact factor (IF) is a metric for assessing academic journals. Despite its shortcomings, the IF is the preeminent yardstick by which the quality of scientific journals is determined. In this paper, the key aspects of the IF are covered from an international perspective, with a specific emphasis on psychiatry journals.
