“…Drawing from theoretical formulations and clinical observations about very early processes of boundary articulation (Blatt and Wild, 1976;Blatt et al, 1975;Jacobson, 1964;Kernberg, 1975Kernberg, , 1976, processes of separation-individuation (Coonerty, 1986;Mahler, Pine, and Bergman, 1975), the formation of the sense of self (Stern, 1985), and the development of increasingly mature levels of interpersonal relatedness and self-definition Blass, 1990, 1996;Blatt and Shichman, 1983), Diamond, Blatt, and colleagues identified two fundamental dimensions of self and object representation: (a) the differentiation of self from other and the integration of a sense of self; and (b) the establishment of increasingly mature levels of interpersonal relatedness. To assess the level of differentiation and relatedness in descriptions of self and significant others, they developed a 10-point scale on which to rate the following points: a lack of basic differentiation between self and other (Levels 1 and 2); the use of mirroring (Level 3), self-other idealization or denigration (Level 4), and an oscillation between polarized negative and positive attributes (Level 5) as maneuvers to consolidate and stabilize representations; an emergent differentiated, constant, and integrated representation of self and other with increasing tolerance for ambiguity (Levels 6 and 7); representations of self and others as empathically interrelated (Level 8); representations of self and other in reciprocal and mutually facilitating interactions (Level 9); and reflectively constructed integrated representations of self and others in reciprocal and mutual relationships (Level 10).…”
