Structural analysis of social behavior (SASB) is a model that can be used to assess interpersonal and intrapsychic interactions in terms of three underlying dimensions: (a) focus (other, self, introject), (b) affiliation-hostility (love-hate), and (c) interdependence-independence (enmeshment-differentiation). Assessment of individuals or groups in terms of these dimensions can be made by self-ratings on the SASB Intrex questionnaires, ratings by others using the same questionnaires, or by objective observer ratings. Data generated by questionnaires or formal codes yield identical summary parameters, making it possible to compare directly objective observer assessments with self-ratings, if desired. The goal of this chapter is to help the reader understand the structure of SASB, become aware of how it has been used in studying interpersonal and intrapsychic events, assess its validity, assess the substance and relevance of criticisms, and consider future possibilities.

In this article, we describe the development and preliminary psychometric properties of the Structured Interview of Personality Organization (STIPO), a semistructured interview designed for the dimensional assessment of identity, primitive defenses, and reality testing, the three primary content domains in the model of personality health and disorder elaborated by Kernberg (1984;Kernberg & Caligor, 2005). Results of this investigation, conducted in a clinical sample representing a broad range of personality pathology, indicate that identity and primitive defenses as operationalized in the STIPO are internally consistent and that interrater reliability for all 3 content domains is adequate. Validity findings suggest that the assessment of one's sense of self and significant others (Identity) is predictive of measures of positive and negative affect, whereas the maladaptive ways in which the subject uses his or her objects for purposes of regulating one's self experience (Primitive Defenses) is predictive of measures of aggression and personality disorder traits associated with cluster B personality disorders. We discuss implications of these findings in terms of the theory-driven and trait-based assessment of personality pathology.

Attachment theory provides a framework for understanding and predicting critical aspects of aggression in the personality disorders. An association between borderline personality disorder (BPD) and insecure forms of adult attachment marked by high relationship anxiety has been repeatedly observed in the empirical literature. Aggression also has been linked to insecure attachment. The present study extends previous work by exploring the degree to which the underlying attachment dimensions of relationship anxiety and avoidance are associated in BPD with the following forms of hostility: (a) direct aggression (verbal or physical) initiated towards others, (b) expectation/perception of aggression from others (including "reactive" counteraggression when/if provoked), (c) aggression directed towards the self in the form of suicidality or parasuicidality, and (d) affective experience of irritability or anger. The issue was studied in a sample of 92 patients diagnosed with BPD. Results show significant association between more fearful forms of attachment (simultaneous presence of relationship anxiety and avoidance) and the more reactive form of aggression involving expectation of hostility from others. Self-harm was significantly associated only with relational avoidance while anger and irritability were associated only with relational anxiety. Implications for understanding relational aspects of BPD aggression in research and clinical work are discussed.
