self-reported

UK: ˌself rɪˈpɔːtɪd | US: ˌself rɪˈpɔːrtɪd

Definition
  1. adj. based on or derived from a person's own account of their behavior, experiences, or condition, rather than external verification.

Structure
self <oneself>report <to give an account>ed <past participle/adjective suffix>
Etymology

The word combines "self," from Old English self (referring to one's own identity), with "report," from Latin reportare (re- "back" + portare "to carry"). The suffix -ed forms a past participle, here functioning as an adjective. The term emerged in the 20th century, reflecting modern emphasis on subjective data in fields like psychology and sociology. It logically progresses from "carrying back information about oneself" to "describing data sourced from personal accounts."
