Development of DSM-5

In 1999, a DSM–5 Research Planning Conference, sponsored jointly by APA and the National Institute of Mental Health (NIMH), was held to set the research priorities. Research Planning Work Groups produced "white papers" on the research needed to inform and shape the DSM-V[clarification needed], and the resulting work and recommendations were reported in an APA monograph and peer-reviewed literature. There were six workgroups, each focusing on a broad topic: Nomenclature, Neuroscience and Genetics, Developmental Issues and Diagnosis, Personality and Relational Disorders, Mental Disorders and Disability, and Cross-Cultural Issues. Three additional white papers were also due by 2004 concerning gender issues, diagnostic issues in the geriatric population, and mental disorders in infants and young children. The white papers have been followed by a series of conferences to produce recommendations relating to specific disorders and issues, with attendance limited to 25 invited researchers.
On July 23, 2007, the APA announced the task force that will oversee the development of DSM-5. The DSM-5 Task Force consists of 27 members, including a chair and vice chair, who collectively represent research scientists from psychiatry and other disciplines, clinical care providers, and consumer and family advocates. Scientists working on the revision of the DSM have experience in research, clinical care, biology, genetics, statistics, epidemiology, public health, and consumer advocacy. They have interests ranging from cross-cultural medicine and genetics to geriatric issues, ethics and addiction. The APA Board of Trustees required that all task force nominees disclose any competing interests or potentially conflicting relationships with entities that have an interest in psychiatric diagnoses and treatments as a precondition to appointment to the task force. The APA made all task force members' disclosures available during the announcement of the task force. Several individuals were ruled ineligible for task force appointments due to their competing interests. Future announcements will include naming the workgroups on specific categories of disorders and their research-based recommendations on updating various disorders and definitions.
The DSM-5 field trials included "test-retest reliability" which involved different clinicians doing independent evaluations of the same patient -- a new approach to the study of diagnostic reliability.
Owing to criticism over the perceived proliferation of diagnoses in the current edition of the DSM, David Kupfer, M.D., who is the DSM-5 Task Force chair and is shepherding the DSM's revision, said in an interview: "One of the raps against psychiatry is that you and I are the only two people in the U.S. without a psychiatric diagnosis."
 First draft diagnostic criteria for DSM-5
The first draft diagnostic criteria for DSM-5 has now been released. Revisions include the following:
The recommendation of new categories for learning disorders and a single diagnostic category, “autism spectrum disorders” that will incorporate the current diagnoses of autistic disorders, Asperger’s Syndrome, childhood disintegrative disorder and pervasive developmental disorder (not otherwise specified). Work group members have also recommended that the diagnostic term “mental retardation” be changed to “intellectual disability,” bringing the DSM criteria into alignment with terminology used by other disciplines.
Eliminating the current categories substance abuse and dependence, replacing them with the new category “addiction and related disorders.” This will include substance use disorders, with each drug identified in its own category. Eliminating the category of dependence will better differentiate between the compulsive drug-seeking behavior of addiction and normal responses of tolerance and withdrawal that some patients experience when using prescribed medications that affect the central nervous system.
Creating a new category of “behavioral addictions,” in which gambling will be the sole disorder. Internet addiction was considered for this category, but work group members decided there was insufficient research data to do so, so they recommended it be included in the manual’s appendix instead, with a goal of encouraging additional study.
New suicide scales for adults and adolescents to help clinicians identify those individuals most at risk, with a goal of enhancing interventions across a broad range of mental disorders; the scales include research-based criteria such as impulsive behavior and heavy drinking in teens.
Consideration of a new “risk syndromes” category, with information to help clinicians identify earlier stages of some serious mental disorders, such as neurocognitive disorder (dementia) and psychosis.
A proposed new diagnostic category, temper dysregulation with dysphoria (TDD), within the Mood Disorders section of the manual. The new criteria are based on a decade of research on severe mood dysregulation, and may help clinicians better differentiate children with these symptoms from those with bipolar disorder or oppositional defiant disorder.
New recognition of binge eating disorder and improved criteria for anorexia nervosa and bulimia nervosa, as well as recommended changes in the definitions of some eating disorders now described as beginning in infancy and childhood to emphasize that they may also develop in older individuals.
In addition to proposed changes to specific diagnostic criteria, the APA is proposing that “dimensional assessments” be added to diagnostic evaluations of mental disorders. These would permit clinicians to evaluate the severity of symptoms, as well as take into account ”crosscutting” symptoms.
Careful Consideration of Gender, Race and Ethnicity
The process for developing the proposed diagnostic criteria for DSM-5 has included careful consideration of how gender, race and ethnicity may affect the diagnosis of mental illness.
 Proposed changes to DSM-IV diagnoses
 Asperger syndrome
Main article: Asperger syndrome
There have been proposals to eliminate Asperger's syndrome as a separate disorder, and instead merge it under autism spectrum disorders (ASD). Under the proposed new classification, clinicians would rate the severity of clinical presentation of ASD as severe, moderate or mild. However, this proposal has inspired much controversy amongst Asperger's Syndrome specialists such as Tony Attwood and Simon Baron-Cohen and opposition groups, such as "Keep Asperger's Syndrome in the DSM-V."
 Attention deficit hyperactivity disorder
Main article: Attention deficit hyperactivity disorder
There has been a proposal to increase the diagnostic criteria for the age when symptoms became present. The proposal would change the diagnostic criteria from symptoms being present before seven years of age to symptoms being present before twelve years of age. The new diagnostic criteria would read: "B. Several noticeable inattentive or hyperactive-impulsive symptoms were present by age 12." 
There has been a proposal that for the Inattentive type and Hyperactive/Impulsive type, a minimum of only four symptoms need to be met if a person is 17 years of age or older. The current DSM-IV-TR criteria of meeting a minimum of six symptoms for the Inattentive type or Hyperactive/Impulsive Type would still apply for those 16 years of age or younger.
 Bipolar disorder
Main article: Bipolar disorder
There have been proposals to include further and more accurate sub-typing for bipolar disorder (Akiskal and Ghaemi, 2006).
There have been proposals for more stringent criteria for the diagnosis of bipolar disorder in children with a new diagnosis temper dysregulation disorder with dysphoria proposed.
Main article: Depression (mood)
While currently grief is only considered a sign of depression if two months have elapsed since the death of a loved one, the new version would allow diagnosis in the first few weeks already. 
 Dissociative identity disorder
Main article: Dissociative identity disorder
Proposed changes to the controversial dissociative identity disorder diagnosis include adding a new diagnostic criterion: "C. Causes clinically significant distress or impairment in social, occupational, or other important areas of functioning." This phrase, which occurs in several other diagnostic criteria, is proposed for inclusion in 300.14 as part of a proposed merger of dissociative trance disorder with DID. Criterion C would be included to "help differentiate normative cultural experiences from psychopathology". For example, professionals would be able to take shamanism, which involves voluntary possession trance states, into consideration, rather than diagnosing those who report it as having a mental disorder.
 Gender identity disorder
Main article: Gender Identity Disorder
Gender Identity Disorder (GID) has been proposed to be renamed as "Gender Dysphoria" in the DSM 5. Along with these changes comes the creation of a separate Gender Dysphoria in Children as well as one for Adults and Adolescents. The grouping will be moved out of the Sexual Disorders category and into its own. The name change was made in part due to stigmatization of the term "disorder" and the relatively common use of "gender dysphoria" in the GID literature and among specialists in the area. The creation of a specific disorder for children reflects the poor insight into what they are experiencing and ability to express it in the event that they have insight.
 Hypersexual disorder
Main article: Hypersexual disorder
Hypersexual Disorder is proposed as a new category to be added. The diagnosis would apply when a person experiences several of the indicated symptoms (extreme amounts of time spent in the sexual activity, using the sexual activity in response to low mood or stress, failed attempts to reduce the behaviors, etc.). Moreover, it would apply only when the problem lasted six months or more, when person experienced significant distress or impairment in major life areas because of it, and when the problem was not directly caused by a medication or drugs, as well as other criteria. Under the proposal, an official diagnosis would also specify which behavior(s) are problematic in the case: masturbation, pornography use, cybersex, etc. 
The label “hypersexual disorder” was reportedly chosen because it did not imply any specific theory for what causes hypersexuality, which remains unknown. A proposal to add sexual addiction to the DSM system has been rejected by the APA, as not enough evidence suggested to them that the condition is analogous to substance addictions, as that name would imply.
The DSM-IV-TR includes "Sexual Disorder—Not Otherwise Specified" (Sexual Disorder NOS), which applies to, among other conditions, “distress about a pattern of repeated sexual relationships involving a succession of lovers who are experienced by the individual only as things to be used.”
 Oppositional Defiant Disorder
Main article: Oppositional Defiant Disorder
It is proposed that the eight symptoms of Oppositional Defiant Disorder should be divided into the following categories: Angry/Irritable Mood; Defiant/Headstrong Behavior; and Vindictiveness. However, just as in the DSM-IV-TR, four of these symptoms need to be present to meet diagnostic criteria. The minimum four symptoms can come from all (or even just one or two) of the three categories.
It is proposed that a section be added to the diagnostic criteria for Oppositional Defiant Disorder stating that for children under 5 years of age, oppositional behavior "must occur on most days for a period of at least six months". For children 5 years or older, oppositional behavior "must occur at least once per week for at least six months". The current criteria states that four or more symptoms must be present for at least 6 months. The proposed change adds the criterion of frequency of symptoms and also delineates required frequency by the age of the child.
 Personality disorders
Main article: Personality disorder
Major changes have been proposed in the assessment and diagnosis of personality disorders. These include a revamped definition of personality disorder and a dimensional rather than a categorical approach based on the severity of dysfunctional personality trait domains (negative emotionality, introversion, antagonism[disambiguation needed ], disinhibition, compulsivity, and schizotypy). In addition, patients would be assessed on how much they match each of six prototypic personality disorder types: antisocial/psychopathic, avoidant, borderline, narcissistic, obsessive-compulsive, and schizotypal with their criteria being derived directly from the dimensional personality trait domains. Some former personality disorders, like histrionic personality disorder, will be submerged under facets of various personality type domains (in this case, the narcissism and histrionism facets of antagonism).
Main article: Pica (disorder)
It is proposed that Pica is reclassified from the "Disorders Usually First Diagnosed in Infancy, Childhood, or Adolescence" classification to the "Eating Disorders" classification.
It is proposed that the wording of "non-food substances" be added alongside the current DSM-IV-TR wording of "non-nutritive substances". "Non-food" was added to further clarify that items consumed are not just merely lacking nutrients (diet soda, according to the DSM-V committee, is an example of a non-nutritive substance), but are actual non-foodstuffs.
 Posttraumatic stress disorder
