Pathology of the mind
Abnormal Psychology is the application of psychological science to the study of mental disorders.
The line dividing normal from abnormal is not always clear.
5. RECOGNIZING THE PRESENCE OF A DISORDER Mental disorders are typically defined by a set of characteristics.
One symptom by itself is seldom sufficient to make a diagnosis.
Syndrome:
A group of symptoms that appear together and are assumed to represent a specific type of disorder.
6. RECOGNIZING THE PRESENCE OF A DISORDER
Mental disorders are defined in terms of:
Duration or persistence of maladaptive behaviors
Impairment in the ability to perform social and occupational roles

Individual experience of personal distress

11. DEFINING ABNORMAL BEHAVIOR Harmful dysfunctionJerome Wakefield
The condition results from the inability of some internal mechanism to perform its natural function.
The condition causes some harm to the person as judged by the standards of the persons culture.
Not every dysfunction leads to a disorder.
12. DEFINING ABNORMAL BEHAVIOR Harmful Dysfunction (continued)
The DSM-IV-TR (APA, 2000) definitions places primary emphasis on the consequences of certain behavioral syndromes.
Mental disorders are defined by clusters of persistent, maladaptive behaviors that are associated with personal distress (ex: anxiety or depression, impairment in social or occupational functioning).
14. DEFINING ABNORMAL BEHAVIOR
Culture is defined in terms of values, beliefs, and practices that are shared by a specific community or group of people. Culture has a profound influence on opinions regarding the difference between normal and abnormal.
15. Culture Relativism --- the conceptions of truth and moral values are not absolute but are relative to the persons or groups holding them. What is considered normal and abnormal differs widely across cultures and over time.
Cultural relativism
Historical relativism

17. Culture There have been many instances in which groups representing particular social values have brought pressure to bear on decisions shaping the diagnostic manual.
18. What is the difference between normal and abnormal behavior? The differences between abnormal and normal behavior are essentially differences in degree, (quantitative differences).

20. WHO EXPERIENCES ABNORMAL BEHAVIOR? Cross-Cultural Comparisons
All mental disorders are shaped, to some extent, by cultural factors.
Do we see eating disorders in countries where there is famine?
Have depression and anxiety increased recently?
No mental disorders are entirely due to cultural or social factors.
Psychotic disorders are less influenced by culture than are nonpsychotic disorders.
The symptoms of certain disorders are more likely to vary across cultures than are the disorders themselves.
21. Who Experiences Abnormal Behavior? Frequency in and Impact on Community Populations
Epidemiology: the scientific study of the frequency and distribution of disorders within a population. Have there been increases/decreases in the diagnosis of disorders? Which ones? In specific areas? What role did gender, SES, race play?
Incidence: the number of new cases of a disorder that appear in a population during a specific period of time.
Lifetime prevalence: total proportion of people in a given population who have been affected by the disorder at some point during their lives.
22. WHO EXPERIENCES ABNORMAL BEHAVIOR? Frequency in and Impact on Community Populations
Lifetime Prevalence and Gender Difference
The National Comorbidity Survey Replication (NCS-R) found that 46% of the surveyed people received at least one lifetime diagnosis. See page 12 Figure 1-1
Epidemiological studies consistently find gender differences for many types of mental disorders.
23. FIGURE 1-1 Lifetime prevalence rates for various mental disorders (NCS-R data)
24. Who Experiences Abnormal Behavior? Frequency in and Impact on Community Populations
Comorbidity and Disease Burden
The presence of more than one condition within the same period of time. 23 percent of the people in the NCS sample had three or more lifetime disorders, and 50% were rated as being severe.
25. How does the impact of mental disorders compare with that of other health problems? Epidemiologists measure disease burden by combining factors of mortality and disability.
Although mental disorders are responsible for only 1% of all deaths, they produce 47% of all disability in developed countries and 28% of all disability worldwide.
26. THE MENTAL HEALTH PROFESSIONS Psychiatry: branch of medicine concerned with the study and treatment of mental disorders.
