Responding to Violence, Suicide, Psychosis and Trauma

Antisocial Personality, Sociopathy, and Psychopathy

I’m aware that although I use these terms on various courses (“Difficult, Disturbing and Dangerous Behaviour” and “Working with Violent Perpetrators” there is considerable confusion and media hype about the use of the above terms. So I thought I woulkd put together a series of postings (for the most part lifted from the literature) to sort out what we are talking about. This has been prompted by a very interesting study that I recently came across “Validating female psychopathy subtypes: Differences in personality, antisocial and violent behavior, substance abuse, trauma, and mental health” – unfortunately to interpret the study would, for many of us, be like a new language.

A very helpful article in this respect can be found at I will take some quotes directly from that site:

People who cannot contain their urges to harm (or kill) people repeatedly for no apparent reason are assumed to suffer from some mental illness. However, they may be more cruel than crazy, they may be choosing not to control their urges, they know right from wrong, they know exactly what they’re doing, and they are definitely NOT insane, at least according to the consensus of most scholars (Samenow 2004). In such cases, they usually fall into one of three types that are typically considered aggravating circumstances in addition to their legal guilt — antisocial personality disorder (APD), sociopath, or psychopath — none of which are the same as insanity or psychosis. APD is the most common type, afflicting about 4% of the general population. Sociopaths are the second most common type, with the American Psychiatric Association estimating that 3% of all males in our society are sociopaths. Psychopaths are rare, found in perhaps 1% of the population.
