BDD beliefs are characterized by varying degrees of insight, ranging from good (ie, recognition that one's BDD beliefs are not true) through \u201cabsent insight\/delusional\u201d beliefs (ie, complete conviction that one's BDD beliefs are true). The <jats:italic>Diagnostic and Statistical Manual of Mental Disorders<\/jats:italic>, 3rd ed., rev. (DSM-III-R) and The <jats:italic>Diagnostic and Statistical Manual of Mental Disorders<\/jats:italic>, 4th ed. (DSM-IV) classified BDD's nondelusional form in the somatoform section of the manual and its delusional form in the psychosis section, as a type of delusional disorder, somatic type (although DSM-IV allowed double-coding of delusional BDD as both a psychotic disorder and BDD). However, little or no evidence on this issue was available when these editions were published. In this article, we review the classification of BDD's delusional and nondelusional variants in earlier editions of DSM and the limitations of their approaches. We then review empirical evidence on this topic, which has become available since DSM-IV was developed. Available evidence indicates that across a range of validators, BDD's delusional and nondelusional variants have many more similarities than differences, including response to pharmacotherapy. Based on these data, we propose that BDD's delusional and nondelusional forms be classified as the same disorder and that BDD's diagnostic criteria include an insight specifier that spans a range of insight, including absent insight\/delusional BDD beliefs. We hope that this recommendation will improve care for patients with this common and often-severe disorder. This increased understanding of BDD may also have implications for other disorders that have an \u201cabsent insight\/delusional\u201d form.<\/jats:p>","DOI":"10.1017\/s1092852913000266","type":"journal-article","created":{"date-parts":[[2013,5,10]],"date-time":"2013-05-10T04:50:15Z","timestamp":1368161415000},"page":"10-20","source":"Crossref","is-referenced-by-count":56,"title":["Delusional
