Confessionalism: This is a style of poetry that developed in the mid 20th century in the United States. It bothers on deep-sitted issues of subjective pain, distress or psychological trauma. It could be regarded as a form of "autobiographical confessions" - the use of first person pronouns ("I" or "me") with the layout of private-closet experiences. 

Confessionalism is a postmodern movement associated with Lowell Robert, Sylvia Plath and a few other American writers. Like all postmodern thoughts, it poses a cognitive criticism to the outlook of modernity. In simple terms, the shell of personalisation in confessional poetry is a means of telling off the ugliness of modernity.
