Final answer:
Substance related disorders create a psychological dependence with emotional needs for a drug, often used to relieve psychological distress. Dependence may include compulsive drug use despite adverse effects and includes criteria detailed in the DSM-5. Rehabilitation typically involves psychotherapy and may be supported by medications or mutual aid groups.
Step-by-step explanation:
Substance related disorders satisfy dependency needs by creating a psychological dependence. This form of dependence is characterized by an emotional, rather than physical, need for a substance. The individual may use the drug to alleviate psychological distress, such as anxiety, depression, or paranoia. While physical dependence is associated with withdrawal symptoms of a physiological nature, psychological dependence is linked with psychological withdrawal symptoms when the substance is no longer used.
In the context of substance use disorders, addiction involves a compulsive use of a substance despite the negative consequences that may result. Dependence can be both physical and psychological, with the latter involving drug cravings even when physical symptoms are not present. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) includes both forms of dependence in its criteria for diagnosing substance use disorders. Rehabilitation often includes psychotherapy and may be supported by mutual aid fellowships like Alcoholics Anonymous or by medications that reduce cravings without causing addiction, such as methadone in heroin addiction treatment.
