I was in the library earlier today re-reading the section on SPD in Personality Disorders in Modern Life, and I noted that Millon makes a distinction between people who have schizoid personality disorder and what he calls a "schizoid style," which is a less severe, non-pathologized form of SPD.
I've written down the descriptions of schizoid personality disorder versus the schizoid style. Which do you think applies more to you? I'd wager that most people who participate on this forum are more accurately described by the schizoid style, but perhaps I'm wrong.
Here it is:
"Those who are disordered neither desire nor enjoy any close relationships, including that of family. This can be contrasted with individuals manifesting a schizoid style; though they are comforted by the quiet and solitude of an asocial lifestyle, they possess the capability to relate to others when necessary.
A schizoid personality usually selects solitary activities resulting in social isolation. Similar to an extent, a schizoid style prefers minimal to no contact when engaged in an activity, yet, unlike the disordered, is willing and able to productively interact when necessary to accomplish a goal.
Sexuality is an undesirable and unexplored realm for a schizoid personality. The schizoid style is also not very sexual, though to a lesser extent; they do occasionally experience sexual feelings.
...the feature distinguishing the schizoid style from the schizoid personality is capability. Both the schizoid style and personality prefer to be asocial, isolated, and asexual, yet only the schizoid style is capable of executing the alternative when necessary.

The disordered find little pleasure in most activities, whereas the style can become engaged in certain hobbies or interests.
In addition, the disordered have no friends or confidants other than those in the immediate family. The styled, on the other hand, have more acquaintances and can sometimes find enjoyment from being part of a small social group.
Much of this is attributed to the fact that those with the disorder are so uninterested in the reactions of others that they remain indifferent to criticism or praise. Conversely, the styled are capable of productively receiving feedback and changing their behavior accordingly if needed.
Emotionally, the disordered may seem cold and detached, with only feeble emotional experiences. This is contrasted with the styled, who are even-tempered with some range of emotion and are capable of experiencing a degree of pleasure and sadness."
