I was on another PTSD site, and amazingly, almost every one of the posters had a narcissist in their life. What gives? Are there that many people diagnosed with narcissistic personality disorder
Eve has already touched on what I'm wanting to say.
There is often a sloppiness in the use of language. Some names and words have very specific and narrow meanings, but very similar word can imply a much looser meaning.
Narcissistic Personality Disorder, is fairly specific.
I had long discussions with my t about the meaning of "personality disorder". My t's day job is working with people who have personality disorders, including NPD.
The names "narcissist", "narcissistic", "psychopathic", "hystrionic" etc
Have far looser meanings, and they don't necessarily imply the level of dysfunction and disorder that a "personality disorder" would describe.
How much dysfunction is required for a diagnosis of "personality disorder" is set out in check lists
For example, someone earlier questioned the credentials of Robert Hare;
The "Hare Psychopathy checklist (revised)" is probably the most used scoring system for diagnosing psychopaths for mental health and legal purposes.
Most places, a score of 30 or above is taken to indicate psychopathic personality disorder. Regular people will score about 3.
But, it is still subjective; for example in Scotland where it's not unusual for people to be obnoxious with drink, foul mouthed, lead parasitic lifestyles (only approximately 1% of the population are net tax contributors), the effective HPCL (R) score for diagnosing someone as a psychopath is about 26 or 27!
There's also the small matter of repeatability between practitioners. This is one of the reasons for the relatively frequent updates of the DSMs, there is great difficulty in achieving repeatability even with specially trained practitioners diagnosing hand picked samples of people in the clinical trials for the DSM!
Ok, just for the sake of simplicity. I'll assume that the diagnostic tools are foolproof and that all of the people out there who qualify for an actual diagnosis of narc personality disorder psychopathic personality disorder etc, have actually been diagnosed
And I'll assume that the figures for each is about 1% of the population.
Those 1%s aren't Island isolated from the main population
They're the extreme tails of some sort of statistical distributions (normal, binomial, log, something of that sort)
Whatever the shape of the distribution, there will still be another group containing several times the number that the group of actual personality disordered people contains,
Who have significantly more traits of the problem personality than the mainstream population do.
They're not clinically personality disordered narcs, psychopaths, histrionics, borderlines, schizoids or whatever
But they have significantly narcissistic, psychopathic, histrionic... personalities
In the case of significantly (but sub clinically) narcissistic or psychopathic people
They're not going to be safe people to be around, and it doesn't need ten years of jumping through
medieval guild professional hoops to realise the gist of where the person is coming from.
I don't know whether the people on the other ptsd site were using the term narc in the strict sense of diagnosed NPD, or the looser sense of narcissistic personality traits.
Language is often used in a sloppy and non precise way.
