Term
Diagnostic Classification System
Definition
Classify the disorders that people have, not the people. Simply put, the person is not the diagnosis.
Term
Disadvantages of Classification
Definition

1. Due to providing information in a shorthand form, an arry of personal details about the actual person is lost.

2. Stigma associated with having a psychiatric diagnosis.

3. Stereotyping (automatic beliefs concerning other people that are based on minimal (often trivial) information)

4. Labeling. Once a group of symptoms is given a name and identified by means of a diagnosis, this "diagnostic label" can be hard to shake even if the person later makes a full recovery.

 

Term
Effect of Classification
Definition

1. Most sciences rely on a classification system that provides us with a nomenclature (a naming system) and enables us to structure information in a more helpful manner.

2. Organizing information within a classification system allows us to study the different disorders and to learn more about what cause them and how they might best be treated.

3. Defining the domain of what is considered to be pathological establishes the range of problems that the mental heal profession can address.

Term
DSM-5 Definition of Mental Disorder
Definition
A behavioral or psychology syndrome (or pattern) that is present in an individual that reflects some kind of underlying psychobiological dysfunction.
Term
DSM-5
Definition
American Psychiatric Association's Manual accepted in the United States, that defines various types of mental disorders.
Term
Culture
Definition
Because decisions about abnormal behavior always involve social judgments and are based on the values and expectations of society at large, means that culture plays a role in determining what is and is not abnormal.
Term
Dangerousness
Definition
Research suggests that in people with mental illness, dangerousness is more the exception than it is the rule.
Term
Irrationality and Unpredictability
Definition
A point at which we consider a given unorthodox behavior abnormal.
Term
Social Discomfort
Definition
When someone violates a social rule, those around her may experience a sense of discomfort or ease
Term
Violations of the Standards of Society
Definition
a behavior is most likely to be viewed as abnormal when it violates the standards of society and is statistically deviant or rare
Term
Statistical Deviancy
Definition
If something is statistically rare and undesirable (as is severely diminished intellectual functioning), we are more likely to consider it abnormal than something that is statistically rate and highly desirable (such as genius) or something that is undesirable but statistically common (such as rudeness)
Term
Maladaptiveness
Definition
Maladaptive behavior is often an indicator of abnormality; however, not all disorders involve maladaptive behavior.
Term
Suffering
Definition
Although suffering is an element of abnormality in many cases, it is neither a sufficient condition (all that is needed) nor even a necessary condition (a feature that all cases of abnormality must show) for us to consider something as abnormal.
Term
The more someone has difficulties in the following areas, the more likely he is to have some form of mental disorder.
Definition

1. Suffering

2. Maladaptiveness

3. Statistical Deviancy

4. Violation of the Standards of Society

5. Social Discomfort

6. Irrationality and Unpredictability

7. Dangerousness

Term
family aggregation
Definition
whether a disorder runs in families
Term
stereotyping
Definition
automatic beliefs concerning other people that we unavoidably learn as a result of growing up in a particular culture
Term
stigma
Definition
a mark of disgrace associated with a particular circumstance, quality, or person.
Term
nomenclature
Definition
naming system
Term
labeling
Definition
assign to a category, especially inaccurately or restrictively
Term
1-year Prevalence figure
Definition
To count everyone who experienced depression at any point in time throughout the entire year.
Term
Point prevalence
Definition
the estimated proportion of actual, active cases of a disorder in a given population at a given point in time.
Term
prevalence
Definition
the number of active cases in a population during any given period of time
Term
Epidemiology
Definition
the study of the distribution of diseases, disorders, or health- related behaviors in a given population
Term
incidence
Definition
refers to the number of new cases that occur over a given period of time
Term
lifetime prevalence
Definition
an estimate of the number of people who have had a particular disorder at any time in their lives
Term
comorbidity
Definition
The presence of two or more disorders in the same person
Term
generalizability
Definition
the extension of research findings and conclusions from a study conducted on a sample population to the population at large
Term
bias
Definition
prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.
Term
case study
Definition
a process or record of research in which detailed consideration is given to the development of a particular person, group, or situation over a period of time.
Term
direct observation
Definition
to have trained observers record the number of times children who are classified as being aggressive hit, bite, push, punch, or kick their playmates
Term
self-report data
Definition
having our research participants complete questionnaires of various types. Another way of collecting self-report data is from interviews. The researcher asks a series of questions and then records what the person says.
Term
hypothesis
Definition
an effort to explain, predict, or explore something.
Term
sampling
Definition
to select people who are representative of the much larger group of individuals with the disorder
Term
criterion group
Definition
People with the disorder being studied
Term
comparison group
Definition
(sometimes called a control group). A group of people who do not exhibit the disorder being studied but who are comparable in all other major respects to the criterion group
Term
internal validity
Definition
reflects how confident we can be in the results of a particular given study
Term
external validity
Definition
The extent to which we can generalize our findings beyond the study itself
Term
correlation coefficient
Definition
The strength that a correlation is measured by
Term
negative correlation
Definition
an inverse correlation  between the variables of interest
Term
positive correlation
Definition
measures vary together in a direct, corresponding manner
Term
correlational research
Definition
studying the world as it is
Term
statistical significance
Definition
the likelihood that a relationship between two or more variables is caused by something other than chance.
Term
third variable problem
Definition
the fact that an observed correlation between two variables may be due to the common correlation between each of the variables and a third variable rather than any underlying relationship (in a causal sense) of the two variables with each other
Term
effect size
Definition
reflects the size of the association between two variables independent of the sample size.
Term
dependent variable
Definition
outcome of interest
Term
independent variable
Definition
factor that is manipulated
Term
experimental research
Definition
scientists control all factors except one—the factor that could have an effect on a variable or outcome of interest
Term
prospective research
Definition
to identify individuals who have a higher-than- average likelihood of becoming psychologically disordered and to focus research attention on them before any disorder manifests.
Term
retrospective research
Definition
to collect information about how the patients behaved early in their lives with the goal of identifying factors that might have been associated with what went wrong later
Term
placebo treatment
Definition
enable experimenters to control for the possibility that simply believing one is getting an effective type of treatment produces a therapeutic benefit
Term
double-blind study
Definition
neither the subjects nor the experimenter who was working with the subjects know who got the actual item, not the placebo
Term
single-case research designs
Definition
case studies used to develop and test therapy techniques within a scientific framework
Term

we study not the true item of interest but an approximation to it.
Term
etiology
Definition
causes of disorders
Term
chronic
Definition
long in duration
Term
acute
