self-reporting

The word 'self-reporting' is a modern English compound formed from three distinct elements. The core, 'report', originates from the Latin 'reportare', meaning "to carry back," which evolved through Old French into the English verb for presenting information. The prefix 'self', of ancient Germanic origin, attaches to specify that the source and subject of the reported information are the same entity. The suffix '-ing', from Old English, converts the verbal action into an adjective or noun, describing the method or act itself. Thus, the term's literal logic—"the carrying back of information by oneself"—perfectly encapsulates its modern use in psychology, research, and data collection, where individuals are the agents documenting their own states or behaviors.
