Final answer:
Dependent personality disorder significantly predisposes an individual to medication abuse, due to a pervasive psychological reliance on others. It is one of several personality traits, including depression, anger, and anxiety that contribute to substance use disorders.
Step-by-step explanation:
Among the psychological or personality factors that may predispose an individual to medication abuse, dependent personality disorder is a significant factor. This disorder is characterized by a pervasive psychological dependence on others, which might lead to medication abuse as the individual seeks comfort or relief. Other factors, such as low self-esteem and unresolved rage, can also contribute by driving an individual to abuse medication in an attempt to alleviate their emotional distress.
Substance use disorder, as defined in DSM-5, captures the compulsive use of drugs despite the occurrence of negative consequences and includes both physical and psychological dependence as diagnostic criteria. Personality traits such as depression, anger, and anxiety have been identified as risk factors for the development of substance use disorders, as they may influence the abuse of medications and other substances to cope with psychological distress.
