As defined by the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV-TR, 2000), a personality disorder (PD) is a persistent pattern of thoughts, feelings, and behaviours that is significantly different from what is considered normal within the person's own culture.

Antisocial personality disorder is specifically a pervasive pattern of disregarding and violating the rights of others. Diagnostic criteria for this disorder state that this pattern must include at least three of the following specific signs and symptoms:
