The ICD-10 is a diagnostic manual, when used by a professional. A professional psychiatrist (by that I mean a non-pill pushing psychiatrist) and psychologists are supposed to take long-term observations of their patients to evaluate the severity of the personality traits. In all of these cases it's the severity
not the presence that determines if you have the disorder or not.
For those listed in the article, here's my winning score for presence of traits that I'm known to have IRL.
The ICD-10 requires at least 4 of the following for an SPD diagnosis:
1 Emotional coldness, detachment or reduced affect.
2 Limited capacity to express either positive or negative emotions towards others.
3 Consistent preference for solitary activities.
4 Very few, if any, close friends or relationships, and a lack of desire for such.
5 Taking pleasure in few, if any, activities.
6 Indifference to social norms and conventions.
7 Preoccupation with fantasy and introspection.
The ICD-10 requires at least four of the following for an AvPD diagnosis:
1 Persistent and pervasive feelings of tension and apprehension.
2 Belief that one is socially inept, personally unappealing, or inferior to others.
3 Excessive preoccupation with being criticized or rejected in social situations.
4 Unwillingness to become involved with people unless certain of being liked.
5 Restrictions in lifestyle because of need to have physical security.
The ICD-10 requires at least 3 of the following for an APSD diagnosis:
1 Gross and persistent attitude of irresponsibility and disregard for social norms, rules, and obligations.
2 Incapacity to experience guilt or to profit from experience, particularly punishment.
3 Markedly prone to blame others or to offer plausible rationalizations for the behaviour that has brought the person into conflict with society.
I'm 1 short on the others except histrionic personality disorder, which I'm at least satisfied I had a zero on.
