What was the primary reason dsm created

Among patients who have similar signs and symptoms, the prognosis might be expected to be similar. Additionally, underlying causes could be identified by finding commonalities in the histories of different patients with the same signs and symptoms.

Finally, treatments found to help one patient might be tried for other patients with the same signs and symptoms [ 11 ]. Medical diagnosis and the ability to differentiate disorders from one another is the foundation of clinical practice. Choosing the most effective treatment depends, for example, on whether the patient has pneumonia, pulmonary embolus, congestive heart failure, or lung cancer.

These different conditions, although they affect the same parts of the body and share some features of their presentation, require different treatments. Differentiating among various disorders is equally important in psychiatry as in the rest of medicine. For example, schizophrenia, mood disorders, and substance use disorders are different illnesses that have been demonstrated to have different prognoses and require different treatments [ 2 , 3 ].

By the late s, medical science was making great advances in the understanding of the biological origins of medical illness, especially with the discovery of bacteria as the source of infectious diseases.

In that era, German physicians Kraepelin and Alzheimer were developing methods to identify neurological causes of disease in some of their patients and to separate diseases such as dementia from other psychiatric illnesses on the basis of biological indicators. They further advanced the notion that mental illness may have a biological basis, and began to organize a framework of psychiatric disorders based on systematic observation of patterns of illness, including characteristic symptoms, course, and outcomes among patients.

Their work, however, was largely ignored by American psychiatry at the time [ 12 ]. It was not until that psychiatry was first recognized as a medical specialty in the United States, by the Association of Medical Superintendents of American Institutions for the Insane, an organization that became the American Psychiatric Association APA in In about , American psychiatry came to be dominated by psychoanalytic theory, an era that lasted approximately two decades [ 13 ].

During this period, American psychiatry emphasized individual differences rather than commonalities in illnesses. Mental processes in psychological health and illness were assumed to be similar. The lack of a unified classification system and the lack of progress toward embracing a biological appreciation of psychiatric illness led to the marginalization of American psychiatry from the rest of medicine [ 12 ].

Psychoanalysis eventually came under attack in American psychiatry with two developments. The first was the discovery of psychiatric medications that were increasingly used for the treatment of major psychiatric illness. The second was the advent of biological research into mental disorders with important new discoveries such as neurotransmitter systems [ 14 ]. The first American initiative to develop standardized diagnostic criteria was prompted by the U.

Census Bureau, to aid efforts to estimate the prevalence of mental disorders in America for the census. This initiative produced a diagnostic manual, the Statistical Manual for the Use of Institutions for the Insane SMUII , which outlined 21 disorders, 19 of which were psychotic disorders. This manual was largely ignored by American psychiatrists, even through the evolution of this document across a series of 10 editions by [ 12 ].

In and , the American Psychiatric Association released its first two versions of its diagnostic criteria for psychiatric disorders, but diagnostic reliability and validity were not to be established until decades later. In , the classic US—UK cross-national study illustrated the importance of having a unified diagnostic system for determining rates of psychiatric illness. Gurland and colleagues [ 15 ] conducted a study to clarify large reported discrepancies between U.

New York City and UK London statistics on the proportions of adults with hospital admissions for schizophrenia and manic-depressive illness. Utilizing semi-structured interviews, ratings of videotapes, and systematic examination of case records, the study found that inconsistent diagnostic methods for routine hospital admissions between the sites were responsible for large discrepancies in diagnosis.

Many of the patients diagnosed with schizophrenia in New York would have been diagnosed with manic-depressive illness in London. Diagnostic agreement would not be possible until reliable diagnostic systems came into existence, such as with DSM-III [ 7 ] in In the midth century, a revolution was beginning in St. Louis, Missouri which would ultimately transform American psychiatry. These academicians were dissatisfied with existing methods of diagnostic classification in psychiatry, which were based more on clinical opinion than on systematic research [ 1 ].

Believing that reliable and valid diagnostic criteria were essential for the field of psychiatry to establish meaningful treatments and conduct scientific research [ 1 , 2 ], this pioneering group set an ambitious goal of developing operationalized diagnostic criteria.

In this work, they specifically avoided theoretical assumptions about the etiology of psychiatric illness in an atheoretical and etiologically agnostic approach to defining psychiatric disorders [ 3 ]. Broader than simply defining disease, this work encompassed strategies for thinking about, studying, and providing care for patients with psychiatric illness. The St. In developing diagnostic criteria for psychiatric disorders, Robins and Guze emphasized the importance of validity whether a coherent syndrome is being measured, and whether it is what it is assumed to be as well reliability the likelihood that different clinicians arrive at the same diagnosis.

To address validity, they adopted a well-established five-phase diagnostic validation model for operationalization of criteria for medical diagnosis. This validation method dates back to work in the 17th century by Thomas Sydenham, and further includes contributions of Koch, Pasteur, and Virchow in the centuries to follow [ 1 , 13 ].

Its application to psychiatric diagnosis in the 20th century, however, was considered radical at the time [ 16 ]. The five phases of diagnostic validation used by Robins and Guze were: 1 clinical characteristics of the syndrome and of the patients who develop it including core symptoms, demographic characteristics, and precipitating factors ; 2 exclusionary criteria differentiating the syndrome from other known disorders; 3 family studies; 4 laboratory data radiological, chemical, pathologic, and psychological evidence ; and 5 follow-up studies for diagnostic stability, course, and treatment response.

The Robins and Guze validation procedure is considered a gold standard for judging different sets of criteria for diagnostic categories. The validation process was intended to be iterative, and adjustments based on the availability of new data to further improve the criteria would always be possible [ 1 , 17 ].

Robins and Guze noted that psychiatric science generally lacked biological evidence, and that more complete diagnostic validation procedures incorporating the fourth phase of validation laboratory data thus awaits future advances in biological science [ 1 ]. The course and outcome to define psychiatric categories of illness related to this third contribution of Robins and Guze had actually already come into use in 19th century Europe, as illustrated by the work of Kraepelin in distinguishing schizophrenia from manic-depressive illness based on its characteristic time course [ 13 ].

Defining diagnoses descriptively and empirically based on characteristic symptoms and course of illness, rather than on theoretically based in assumed etiologies, has practical implications [ 3 ]. Scientifically untested causal assumptions about the etiology of disease may be incorrect, leading to misguided treatment.

An agnostic approach to diagnosis not assuming etiology opens doors to testing of causal hypotheses through epidemiologic, genetic, and neurobiological research.

Helzer and colleagues [ 18 ] pointed out that valid diagnostic criteria are of little use if clinicians cannot consistently agree about a diagnosis attained through application of the criteria, as determined through inter-rater reliability.

The development and measurement of reliability using validated diagnostic criteria, however, would have to await the advent of structured interview methods, which were developed over the next few years and used to document acceptable reliability of established diagnostic criteria [ 19 , 20 , 21 , 22 ].

The American Psychiatric Association set out to create a unified and definitive diagnostic system for all of American psychiatry. Axis V is where the clinician gives their impression of the client's overall level of functioning.

Based on this assessment, clinicians could better understand how the other four axes interacted and the effect on the individual's life. The most immediately obvious change is the shift from using Roman numerals to Arabic numbers. Perhaps most notably, the DSM-5 eliminated the multiaxial system. Instead, the DSM-5 lists categories of disorders along with a number of different related disorders.

Example categories in the DSM-5 include anxiety disorders, bipolar and related disorders, depressive disorders , feeding and eating disorders, obsessive-compulsive and related disorders, and personality disorders. A few other changes in the DSM While the DSM is an important tool, only those who have received specialized training and possess sufficient experience are qualified to diagnose and treat mental illnesses.

Philos Ethics Humanit Med. Despite this, it gained acceptance. Changes in the DSM-II included eleven major diagnostic categories, with total diagnoses for mental disorders. For example the diagnostic category of Behavior Disorders of Childhood-Adolescence was presented for the first time. This dramatically changed the field of psychology. Robert L. Spitzer was appointed to lead the changes to the DSM in He was largely involved in creating the discrete diagnostic categories of the DSM-III, as opposed to a dimensional model of diagnosis.

Before the DSM, there were several different diagnostic systems. So there was a real need for a classification that minimized the confusion, created a consensus among the field and helped mental health professionals communicate using a common diagnostic language. The term reflected a psychodynamic slant Sanders, At the time, American psychiatrists were adopting the psychodynamic approach. It represents a group of psychotic disorders characterized by fundamental disturbances in reality relationships and concept formations, with affective, behavioral, and intellectual disturbances in varying degrees and mixtures.

The former grouping was subdivided into acute brain disorders, chronic brain disorders, and mental deficiency. The latter was subdivided into psychotic disorders including affective and schizophrenic reactions , psychophysiologic autonomic and visceral disorders psychophysiologic reactions, which appear related to somatization , psychoneurotic disorders including anxiety, phobic, obsessive—compulsive, and depressive reactions , personality disorders including schizoid personality, antisocial reaction, and addiction , and transient situational personality disorders including adjustment reaction and conduct disturbance.

It was only slightly different from the first edition. DSM-III dropped the psychodynamic perspective in favor of empiricism and expanded to pages with diagnostic categories. The reason for the big shift? Not only was psychiatric diagnosis viewed as unclear and unreliable but suspicion and contempt about psychiatry started brewing in America. Public perception was far from favorable.

Kraepelin believed that biology and genetics played a key role in mental disorders. Learn more about Kraepelin here and here. Louis, MO, who were dissatisfied with psychodynamically oriented American psychiatry.

Eli Robins, Samuel Guze, and George Winokur, who sought to return psychiatry to its medical roots, were called the neo-Kraepelinians Klerman, They were dissatisfied with the lack of clear diagnoses and classification, low interrater reliability among psychiatrists, and blurred distinction between mental health and illness.
