Understanding Antisocial Personality Disorder

Antisocial personality disorder is a personality disorder involving a long term pattern of disregarding or violating the rights of others. Features can include deceitfulness, impulsivity, irritability and aggression, reckless disregard for safety, ongoing irresponsibility and a lack of remorse. It is diagnosed only in adults by a qualified clinician, and there must be signs of related difficulties from childhood. Key points: many people have experienced childhood adversity or trauma; substance use and other mental health conditions often occur alongside it; psychopath and sociopath are not diagnoses; and some features can lessen with age and support.

Antisocial personality disorder can affect relationships, housing, work, money, health and contact with the justice system. The person may struggle with trust, rules, conflict and planning ahead, and may have lost many relationships and services along the way. They also face higher risks of injury, substance use, depression and suicide. Key points: people are often excluded from services, which increases risk; many carry histories of trauma; behaviour can affect other participants and workers, so safety planning matters; and support should focus on the person's goals and strengths as well as risk.

Supporting a person with antisocial personality disorder works best when you are respectful, consistent and clear. This lesson covers practical approaches: be clear and honest about expectations and limits, apply agreed boundaries the same way every time, avoid power struggles, focus on the person's goals, stay calm, and follow the support plan, behaviour support plan and safety plan. It also covers language: say a person living with antisocial personality disorder, never a psychopath, sociopath or bad person. Key points: respect and safety go together, and consistency across the whole team is essential.

This lesson covers warning signs that need escalating when supporting a person living with antisocial personality disorder, including threats or aggression, carrying weapons, pressuring or exploiting other participants, increasing alcohol or drug use, suspected criminal activity, and self harm or suicidal talk. Key points: your safety matters, so leave and call 000 if there is immediate danger; follow the safety plan and our incident reporting procedures; tell your team leader straight away; record facts; support workers do not diagnose, treat or use restrictive practices outside an authorised behaviour support plan; and Lifeline is on 13 11 14.

This case study follows Wayne, a man living with antisocial personality disorder who has recently moved into supported accommodation after leaving prison. His support plan sets out clear expectations that he helped agree to. When Wayne pushes a support worker to break the plan, the worker needs to stay calm, polite and consistent. The lesson shows how clear boundaries, links to Wayne's own goals and team consistency help him keep his housing. Key points: refer to the agreed plan, avoid power struggles, link to goals and record every boundary test.

This case study is set in a shared supported home where Dean, who lives with antisocial personality disorder, has been pressuring a housemate with an intellectual disability for money and cigarettes. A support worker sees the housemate hand over his bank card. The lesson covers recognising possible financial abuse between participants, keeping everyone safe without confronting anyone alone, and reporting promptly, including incidents that may need to be reported to the NDIS Quality and Safeguards Commission. Key points: protect the person at risk, never investigate alone, report straight away and record the facts.

This case study follows Craig, a man living with antisocial personality disorder who loses his job and starts drinking more. He tells his support worker that everyone would be better off without him, and later becomes angry and blocks a doorway. The lesson covers taking talk of suicide seriously, even when the person has a history of conflict, and putting safety first when there is a threat. It also covers escalation, reporting and debriefing. Key points: always take suicide risk seriously, leave unsafe situations, call 000 when needed and never cope alone.
