Deviation from social standards of acceptable behavior
Ideas of "normal" and "abnormal" are largely shaped by social standards and can have profound social ramifications
What is considered "normal" changes with changing societal standards
Despite the challenges inherent in defining "normal," it is still important to establish guidelines so as to be able to identify and help people who are suffering
The DSM-5 attempts to explicitly distinguish normality from abnormality based on specific symptoms
Society generally sees normality as good and abnormality as bad
Being labeled as "normal" or "abnormal" can have profound ramifications for an individual, such as exclusion or stigmatization by society
Stigma and discrimination can add to the suffering and disability of those who are diagnosed with (or perceived to have) a mental disorder
A recent move has been made toward the adoption of person-centered language: referring to people as "individuals with mental illness" rather than "mentally ill individuals"
Psychological disorder
A condition characterized by abnormal thoughts, feelings, and behaviors
Defining what is "normal" and "abnormal" is a subject of much debate
Definitions of normality vary widely by person, time, place, culture, and situation
"Normal" is a subjective perception, and also an amorphous one—it is often easier to describe what is not normal than what is normal
In simple terms, society at large often perceives or labels "normal" as "good," and "abnormal" as "bad"
It is important to establish guidelines in order to be able to identify and help people who are suffering
The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) lays out explicit and specific guidelines for identifying and categorizing symptoms and diagnoses
According to the World Health Organization (WHO), more than a third of people globally meet the criteria for at least one diagnosable mental disorder at some point in their lives
Stigma and discrimination can add to the suffering and disability of those with mental illness
Stigma
The societal disapproval and judgment of a person or group of people because they do not fit their community's social norms
In the context of mental illness, social stigma is characterized as prejudiced attitudes and discriminatory behavior directed toward individuals with mental illness as a result of the label they have been given
In the United States, people are often pressured to be "normal"—or at least perceived as such—in order to gain acceptance by society
Society tends to be uncomfortable with "abnormality"—so if someone does not conform to what is perceived as normal, they might be given a number of negative labels, such as "sick","crazy", or "psycho"
These labels lead to discrimination, marginalization, and isolation of—even violence against—the individual
Self-stigmatization
When someone internalizes society's negative perceptions of them or of people they think are like them
Self-stigmatization contributes to feelings of shame and usually leads to poorer treatment outcomes
Experience of stigma or self-stigma can lead to refusal to receive treatment, social isolation, and distorted perception of the incidence of mental illness
Stigmas are usually deeply ingrained in society over many years and so cannot be eradicated instantly
With the rising awareness that mental illness affects so many people globally, more and more is being done to reduce the stigma associated with such illnesses
The field of psychology has recently moved toward using deliberate person-centered language—referring to people as individuals with mental illness rather than mentally ill individuals
Abnormal behavior
The scientific study of abnormal behavior, with the intent to be able to reliably predict, explain, diagnose, identify the causes of, and treat maladaptive behavior
