Psychological Disorders

SECTION 1

What Are Psychological Disorders?

Quick Definitions

Psychological Disorders: patterns of thoughts or behaviors that interfere with lives or cause suffering

Culture-Bound Syndromes: what we consider a disorder may actually be considered normal in other areas

Did You Know?

How many Americans suffer from psychological disorders?

Studies vary, but the results range from one-fourth up to half!

For the test, we’ll say: One-third of adults in the United States

have experienced some type of psychological disorder.

Symptoms

1. Typicality—is the behavior average of the rest of society?

2. Maladaptive Behavior—determines whether the behavior is harmful to self or others

3. Emotional Discomfort—if a person suffers from extreme or long-lasting feelings of hopelessness or helplessness

4. Socially Unacceptable Behaviors—actions that violate society’s norms

Classifying Psychological Disorders

It’s important to have a system for classifying disorders for diagnosis and treatment.

Disorders were first classified based on their presumed causes.

Today, psychologists use the DSM-IV to classify disorders. DSM-V: Diagnostic and Statistical Manual of

Mental Disorders; 5th edition (first published in 1960)
