Final answer:
Antisocial personality disorder, characterized by persistent disregard for others' rights, deceit, and irresponsibility, can explain an individual's chronic irritability, aggression, and irresponsibility. DSM-5 recognizes antagonism and disinhibition as the primary traits associated with this disorder. Both genetic and environmental factors contribute to its development.
Step-by-step explanation:
An individual who is typically irritable, aggressive, and irresponsible might be diagnosed with antisocial personality disorder. This disorder is characterized by a sustained disregard for the rights of others, expressed through recurring illegal acts, deceit, impulsivity, reckless behaviors, and failure to act responsibly (APA, 2013). People with antisocial personality disorder are unremorseful; they can harm, manipulate, and exploit others without experiencing guilt. The disorder manifests itself early in life, but a diagnosis cannot be made until the individual is at least 18 years old.
According to DSM-5, antisocial personality disorder is primarily characterized by antagonism and disinhibition. Antagonism includes disregard for others' needs, manipulative or deceitful behavior while disinhibition involves impulsivity, irresponsibility, and risk-taking.
Genetic and environmental factors both play a role in this disorder. Antisocial personality disorder is seen in approximately 3.6% of the population and is more common in men and those of lower socioeconomic status. Women with this disorder frequently report a history of emotional neglect and sexual abuse in their childhood (Alegria et al., 2013).
