The Diagnostic and Statistical Manual of Mental Disorders is a publication by the American Psychiatric Association (APA) for the classification of mental disorders using a common language and standard criteria.
A mental disorder, also called a mental illness or psychiatric disorder, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. Such features may be persistent, relapsing and remitting, or occur as a single episode. Many disorders have been described, with signs and symptoms that vary widely between specific disorders. Such disorders may be diagnosed by a mental health professional.
Schizoaffective disorder is a mental disorder characterized by abnormal thought processes and an unstable mood. The diagnosis is made when the person has symptoms of both schizophrenia and a mood disorder—either bipolar disorder or depression. The main criterion for the schizoaffective disorder diagnosis is the presence of psychotic symptoms for at least two weeks without any mood symptoms present. Schizoaffective disorder can often be misdiagnosed when the correct diagnosis may be psychotic depression, psychotic bipolar disorder, schizophreniform disorder, or schizophrenia. It is imperative for providers to accurately diagnose patients, as treatment and prognosis differs greatly for each of these diagnoses.
Delusional disorder is a generally rare mental illness in which a person presents delusions, but with no accompanying prominent hallucinations, thought disorder, mood disorder, or significant flattening of affect. Delusions are a specific symptom of psychosis. Delusions can be bizarre or non-bizarre in content; non-bizarre delusions are fixed false beliefs that involve situations that occur in real life, such as being harmed or poisoned. Apart from their delusion or delusions, people with delusional disorder may continue to socialize and function in a normal manner and their behavior does not necessarily generally seem odd. However, the preoccupation with delusional ideas can be disruptive to their overall lives.
The World Psychiatric Association is an international umbrella organisation of psychiatric societies.

The Feighner Criteria are a set of influential psychiatric diagnostic criteria developed at Washington University in St. Louis, Missouri from the late 1950s to the early 1970s.
Cross-cultural psychiatry is a branch of psychiatry concerned with the cultural context of mental disorders and the challenges of addressing ethnic diversity in psychiatric services. It emerged as a coherent field from several strands of work, including surveys of the prevalence and form of disorders in different cultures or countries; the study of migrant populations and ethnic diversity within countries; and analysis of psychiatry itself as a cultural product.
The Chinese Classification of Mental Disorders, published by the Chinese Society of Psychiatry (CSP), is a clinical guide used in China for the diagnosis of mental disorders. It is currently on a third version, the CCMD-3, written in Chinese and English. It is intentionally similar in structure and categorisation to the ICD and DSM, the two most well-known diagnostic manuals, though it includes some variations on their main diagnoses and around 40 culturally related diagnoses.
The classification of mental disorders is also known as psychiatric nosology or psychiatric taxonomy. It represents a key aspect of psychiatry and other mental health professions and is an important issue for people who may be diagnosed. There are currently two widely established systems for classifying mental disorders:
Child and adolescent psychiatry is a branch of psychiatry that focuses on the diagnosis, treatment, and prevention of mental disorders in children, adolescents, and their families. It investigates the biopsychosocial factors that influence the development and course of these psychiatric disorders and treatment responses to various interventions.
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is the 2013 update to the Diagnostic and Statistical Manual of Mental Disorders, the taxonomic and diagnostic tool published by the American Psychiatric Association (APA). In the United States, the DSM serves as the principal authority for psychiatric diagnoses. Treatment recommendations, as well as payment by health care providers, are often determined by DSM classifications, so the appearance of a new version has practical importance. The DSM-5 is the first DSM to use an Arabic numeral instead of a Roman numeral in its title, as well as the first "living document" version of a DSM.

In personality pathology, dimensional models of personality disorders conceptualize personality disorders as quantitatively rather than qualitatively different from normal personality. They consist of extreme, maladaptive levels of certain personality characteristics. Within the context of personality psychology, a "dimension" refers to a continuum on which an individual can have various levels of a characteristic, in contrast to the dichotomous categorical approach in which an individual does or does not possess a characteristic. According to dimensional models personality disorders are classified according to which characteristics are expressed at which levels. This stands in contrast to the traditional categorical models of classification, which are based on the boolean presence or absence of symptoms and do not take into account levels of expression of a characteristic or the presence of any underlying dimension.
