Asperger's syndrome and schizoid personality disorder have many features in common: flat affect, monotonous voice, and impaired socialization. I am curious how many of you have traits of a schizoid personality. Although schizoid personality disorder technically excludes Asperger's syndrome, a person with Asperger's syndrome can show traits of a schizoid personality.
For each criterion of schizoid personality disorder, decide how well it applies to you personally. If it doesn't apply at all, score it as 0; if it is somewhat applicable, score it as 1; and, if it describes you quite well, score it as a 2. The minimum possible score is 0; the maximum possible score is 18. For an ICD-10 diagnosis of F60.1 schizoid personality disorder, four criteria must be met. I measured myself as having a score of 8.
ICD-10 wrote:
(a)few, if any, activities, provide pleasure;
(b)emotional coldness, detachment or flattened affectivity;
(c)limited capacity to express either warm, tender feelings or anger towards others;
(d)apparent indifference to either praise or criticism;
(e)little interest in having sexual experiences with another person (taking into account age);
(f)almost invariable preference for solitary activities;
(g)excessive preoccupation with fantasy and introspection;
(h)lack of close friends or confiding relationships (or having only one) and of desire for such relationships;
(i)marked insensitivity to prevailing social norms and conventions.
Excludes: Asperger's syndrome (F84.5)
delusional disorder (F22.0)
schizoid disorder of childhood (F84.5)
schizophrenia (F20.-)
schizotypal disorder (F21)
Additionally, to diagnose schizoid personality disorder, the general criteria for any specific personality disorder must be met.ICD-10 wrote:
F60 SPECIFIC PERSONALITY DISORDERSG1. Evidence that the individual's characteristic and enduring patterns of inner experience and behaviour deviate markedly as a whole from the culturally expected and accepted range (or 'norm'). Such deviation must be manifest in more than one of the following areas:
- cognition (i.e. ways of perceiving and interpreting things, people and events; forming attitudes and images
of self and others); - affectivity (range, intensity and appropriateness of emotional arousaland response);
- control over impulses and need gratification;
- relating to others and manner of handling interpersonal situations.
G2. The deviation must manifest itself pervasively as behaviour that is inflexible, maladaptive, or otherwise dysfunctional across a broad range of personal and social situations (i.e. not being limited to one specific 'triggering' stimulus or situation).
G3. There is personal distress, or adverse impact on the social environment, or both, clearly attributable to the behaviour referred to under G2.
G4. There must be evidence that the deviation is stable and of long duration, having its onset in late childhood or adolescence.
G5. The deviation cannot be explained as a manifestation or consequence of other adult mental disorders, although episodic or chronic conditions from sections F0 to F7 of this classification may co-exist, or be superimposed on it.
G6. Organic brain disease, injury, or dysfunction must be excluded as possible cause of the deviation (if such organic causation is demonstrable, use category F07).
I botched the scoring. Consider 13-18 severe. I miscounted the number of criteria by one with the original post.
