Step-by-step explanation:
According to research, the prevalence of antisocial personality disorder in the general population ranges from 0.2% to 3.3%, depending on the definition used. A study conducted in the United States reported a prevalence of 1% for antisocial personality disorder. It's important to note that the diagnosis and classification of personality disorders can be controversial and there may be variations in estimates.
In terms of prognosis, there is evidence to suggest that individuals with antisocial personality disorder who do not have psychopathic traits are more likely to see improvement in their symptoms. Psychopathic traits, such as a lack of remorse or empathy, are associated with a poorer prognosis. However, it's important to consult with a mental health professional for a comprehensive evaluation and personalized prognosis.
