Introject and identity: structural-interpersonal analysis and psychological assessment of multiple personality disorder.
Revisions of the diagnostic nomenclature have contributed to renewed interest in multiple personality disorder (MPD). Identity and self-organization in MPD are assessed using a sophisticated structural-interpersonal measurement system, Structural Analysis of Social Behavior (SASB). Two important features of the SASB model applied to MPD are the assessments of interpersonal perceptions of childhood initiators of abuse and of the introject or self-organization of host and secondary personalities. SASB findings from a clinical series of six cases of MPD are analyzed to illustrate the use of this assessment technique. Host personalities and abused secondary personalities differed in their identity and self-organization. Host personalities evidenced internalization of abuse dynamics related to self-destructive trends. Secondary personalities, despite having experienced abuse, did not manifest such dynamics. Implications for understanding personality processes in MPD and for further research are discussed.
