Antisocial personality disorder

Antisocial personality disorder shows up in court-referred, substance-use and partner-violence cases, and the exam tests one gatekeeping fact more than any other: no conduct disorder before 15, no ASPD.

Criteria at exam depth. A pervasive pattern of disregard for and violation of others' rights occurring since age 15, with three of seven features: repeated unlawful acts, deceitfulness (lying, aliases, conning), impulsivity or failure to plan, irritability and aggression (repeated fights or assaults), reckless disregard for safety, consistent irresponsibility (work, finances), and lack of remorse (indifference or rationalizing harm). Three gatekeepers:

• the client is at least 18;
• there is evidence of conduct disorder with onset before age 15;
• the behavior does not occur only during schizophrenia or bipolar disorder.

Hinge differentials.

• Conduct disorder — the diagnosis for clients under 18; ASPD requires adulthood.
• Substance use disorder — antisocial acts only while obtaining or using substances, without a childhood conduct-disorder history, point to the SUD alone; both can be diagnosed when the pattern predates and extends beyond use.
• Narcissistic PD — exploitation driven by need for admiration and idealize-devalue cycles, usually without the aggression, criminality and childhood conduct problems.
• Intermittent explosive disorder — impulsive outbursts followed by genuine remorse, without the broader pattern of deceit and exploitation.
• Borderline PD — impulsivity driven by abandonment fear and emotional pain, not callous gain.
• Manic episode — antisocial acts confined to a discrete mood episode.
• Adult antisocial behavior (a non-disorder condition) — criminal or exploitative acts without the full personality pattern.

On the NCMHCE. Your first duty is risk to others: assess violence history, access to weapons, intimate-partner and child-safety concerns, and follow duty-to-warn/protect law and mandated-reporting rules for your state. Screen for co-occurring substance use, which is common and often the more treatable target. Gather collateral and records (juvenile history, court documents) because self-report may be unreliable — while staying nonjudgmental. Treatment targets concrete, self-interested goals (staying out of jail, keeping custody), using motivational interviewing and cognitive-behavioral, skills-based approaches; set firm, explicit limits and document carefully. Mandated clients need clear informed consent about what will be reported to the court or probation officer. Guard against bias: arrest records reflect policing patterns as well as behavior, so do not infer the diagnosis from legal history or neighborhood alone — the full pattern, including childhood conduct disorder, must be there.

Clinical Pearl: Age 18+, conduct disorder evidence before 15, three of seven features, not only during psychosis or mania. Genuine remorse after aggression points away from ASPD.
