Diagnostic boundaries, reasoning and depressive disorder, I. Development of a probabilistic morbidity model for public health psychiatry.

In recent years, diagnostic methods in psychiatry have become more systematic, attempting to standardize disease definitions and improve reliability. At the same time, there is a growing awareness of the need to take uncertainty in diagnostic decision-making into account. In most cases, the diagnosis is still represented by binary results, and it is known that large amounts of information are lost. In many diagnostic scenarios, you need a threshold to get the number of symptoms from the list of symptoms.

This is a model that uses ideas derived from potential category analysis to extend these schemes from binary to mental case state probability measurements and to replace thresholds with smooth transitions.

Without changing the meaning of the original measurement value, a result measurement is generated in which the disordered state is probably represented. Estimates of prevalence (using ICD-10 depression episode criteria) are more stable and can be shown more accurately

The disordered state thus expressed preserves more diagnostic information and provides a useful extension to traditional dual analysis when viewing estimates of prevalence and risk factors.

Throughout the history of psychiatry, experts have discussed the boundary between BPD and other mental health conditions such as schizophrenia, depression, posttraumatic stress disorder, bipolar disorder. The diagnostic criteria for BPD were first published in the 1970's and then officially included in the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM - III). In 1992, the World Health Organization added this condition to the ICD - 10. Today, researchers and psychiatrists agree that BPD is a unique disease.

Since many symptoms overlap with other mental health conditions such as depression, substance abuse, eating disorders, post traumatic stress disorder, bipolar disorder, psychosis and other personality disorders, accurate diagnosis of BPD It is often difficult. Individuals may have signs of BPD diagnosis and complications of other psychoses. For accurate assessment, nurses and nurses need to be able to identify risk factors, aura, and related clinical features.

Children and adolescents are facing major challenges in diagnosing drug abuse disorders. Diagnostic evaluation often focuses on certain co-morbidities such as depression and / or behavior disorders or pre-complication symptoms. This can lead to abuse or abuse of substance abuse. This is a common issue for young people, as young people are often concerned about being punished for their actions and in most cases refuse to try drugs. They may also feel intimidated if the interviewees are not sufficiently sensitive to the substance abuse issue. The need for young people to experiment and break through the limit also causes confusion. Therefore, careful collection of information that can quantify existing conditions related to abuse is required for evaluation of substance abuse.
