There is a variant of schizoid personality which shows some similar signs of dependency to DPD:
The 'Higher Level' schizoid
"Because the [higher level] schizoid has not had the benefit of an
experience of contact and trust in infancy, the most positive
relationship that he can manage is one in which he is not being
attacked. He accomplishes this by assuming a part self representation of a trapped, helpless, completely comliant person relating to another person whom he perceives as rigid, easily offended, and extremely controlling. These slave and master representations are linked to affects of fear, anxiety, obsessive caution, and control. The higher level schizoid perceives the master/slave unit ambivalently, an acceptable alternative to exile, but one in which he sacrifices his autonomy and much of his self esteem in return for security and some sense of relatedness. He prefers this to the more distancing alternative. (taken from- http://groups.msn.com/SCHIZOIDPERSONALI ... ERCHATSITE )
The "high level" schizoid apparently has many of the fears of
abandonment and rejection, but unlike the DSM dependent is capable of
making decisions for themselves.... its just that they don't choose
to because other people might reject them: "Unable to tolerate the
inability to control human relationships, the schizoid often
transfers his libidinal investment to nonhuman things. What is at
issue is that the other individual in a relationship is free to
reject him. Given his extreme sensitivity to rejection, the schizoid
person cannot tolerate the subjective freedom of the other. If the
schizoid becomes involved in a human relationship, he must be totally
compliant or may attempt to transform the other into a thinglike
object." PS. some more information from the same site:
