Mental representation is a central construct in psychological development.
A method for assessing the developmental level of representation of self an
d significant figures is described, and changes in the developmental level
of these representations are reported in a sample of forty seriously distur
bed, treatment-resistant adolescents and young adults in intensive, psychoa
nalytically oriented inpatient treatment lasting more than a year. Increase
d differentiation-relatedness of descriptions of self and significant figur
es (mother, father, and therapist) was significantly correlated with improv
ed clinical functioning. Over the course of treatment, representations move
d from descriptions of self and significant figures dominated by polarizati
on and splitting to representations involving the emergence and consolidati
on of object constancy. Improved clinical functioning was correlated with m
ore positive descriptions of self, mother, and therapist and, paradoxically
, with more negative descriptions of father. Two prototypical case studies
of these self- and significant-figure descriptions are presented, one for a
borderline patient and one for a schizophrenic. Intense negative affect, p
redominantly anger, and a relative preservation of self-reflexivity are typ
ical of the self- and object representations of borderline individuals, but
representations in schizophrenic individuals are characterized by affectiv
e muting and marked disturbance in reflexive self-awareness. The assessment
of cognitive-affective schemas of self and significant others provides a m
ethod for investigating therapeutic change and for identifying important di
fferences among various forms of psychopathology.
