Using the structural analysis of social behavior (SASB) to differentiate young adults with borderline personality disorder features.

The present experiment investigated the ability of the Structural Analysis of Social Behavior (SASB) Intrex questionnaires to differentiate nonclinical samples of young adults with features of either borderline personality disorder (BPD), schizotypal personality disorder (SPD), or no personality disorder (no PD). A number of significant differences were demonstrated on the SASB Intrex questionnaires when comparisons were made between the BPD and no PD samples. These results are consistent with those reported in an earlier investigation of BPD using SASB in a clinical sample. Few differences were found between the SPD features sample and the other two samples. These results are not consistent with previous findings that have differentiated BPD and SPD in clinical samples. The results are discussed in terms of the possible implications for SASB to differentiate BPD, the use of nonclinical samples in personality disorder research, and dimensional models for conceptualizing personality disorders.
