Various authorities criticized the fifth edition both before and after it was formally published. Critics assert, for example, that many DSM-5 revisions or additions lack empirical support; inter-rater reliability is low for many disorders; several sections contain poorly written, confusing, or contradictory information; and the psychiatric drug industry unduly influenced the manual's content. Many of the member of work groups for the DSM-5 had conflicting interests, including ties to pharmaceutical companies.
