“The Four Ds”:
Deviance – Different, extreme, unusual
Distress – Unpleasant and upsetting
Dysfunction – Causes interference with life
Danger – Poses risk of harm
Deviance: From What?
From behaviors, thoughts & emotions considered normal in a specific place, time and by specific people From social norms
Stated and unstated rules for proper conduct in a given society or culture
According to many clinical guidelines, behavior must be personally distressing before it can be labeled abnormal Breakdown in cognitive, emotional, or behavioural functioning Example:

Personality Disorders
Eating Disorders
Abnormal behavior tends to be dysfunctional – it interferes with daily functioning Difficulty performing appropriate and expected roles
Culture has an influence on determinations of dysfunction as well Dysfunction alone does not mean abnormality
Abnormal behavior may become dangerous to oneself or others Behavior may be careless, hostile, or confused
Although cited as a feature of psychological abnormality, dangerousness is the exception rather than the rule The Elusive Nature of Abnormality
Ultimately, a society selects the general criteria for defining abnormality and then uses those criteria to judge particular cases Szasz argues that, because of the influence of culture, the whole concept of mental illness is invalid {text:list-item} {text:list-item}
