Which of the following was explained in the Psychological Disorders Learning
Resource #5 video (first video in Learning Resource #5)?
A person has a genetic predisposition for addiction due to a family history of substance
abuse. Then the person faces social isolation, unemployment, and personal conflicts. The
genetic vulnerability interacts with adverse life circumstances to increase the risk of
developing a substance use disorder.
In order for abnormal behavior to be identified as a disorder, there must be significant
deviance, distress, and dysfunction.
The two classification systems for diagnosing disorders are the International Classification of
Diseases (ICD-10) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
The DSM-5 is used by psychological professionals for providing consistent criteria for
diagnosing individuals with mental disorders.
Neurotransmitter imbalances, particularly involving GABA (gamma-aminobutyric acid), are
implicated in anxiety disorders. Genetics can also play a role in an individual's susceptibility.
