title: Adjustment disorder: new developments.
abstract: Adjustment disorders (ADs) have been included in the psychiatric classifications since 1952 although their name has changed over time. In DSM 5 they have been classified under the trauma and stress related disorders for the first time. Despite this positive step, there are still problems with the classification of ADs. There is no guidance on the distinction from normal stress reactions, it remains a subthreshold category, and the subtypes are not strongly underpinned by research. There are no specific diagnostic criteria in terms of symptom numbers or combinations of these, unlike most other conditions classified in DSM. Apart from epidemiological studies in those with medical illnesses, recent prevalence studies in other populations are scarce. Research is lacking in many aspects of AD, especially their biological underpinnings and treatments. One factor contributing to this is the absence of adequate diagnostic interview schedules. Interest in ADs may increase now that they are classified with the trauma-related group of disorders.
