Total scores of the Raven's Standard Progressive Matrices (SPM) were correlated with Wechsler Adult Intelligence Scale‐Revised Full Scale IQs (WAIS‐R FSIQ) in order to obtain age‐stratified estimates of WAIS‐R FSIQ (N = 308). Results show a significant positive correlation between age‐stratified WAIS‐R FSIQ and SPM in all age groups except those 65 and older and between educational level and SPM for all age groups except the very young (16 to 24 years), the 55‐ to 64‐year‐olds, and the elderly (65 and older). A multiple regression and cross‐validation revealed that race and age also must be used as moderator variables when one is predicting FSIQ in this population. It is concluded that the SPM can be used as an estimate of WAIS‐R FSIQ.

This study is an attempt to delineate symptom clusters that may be considered most distinctive of patients diagnosed with borderline personality disorder (BPD). Medical records were examined to assess the extent to which each of the eight DSM‐III‐R BPD criteria was present in 89 psychiatric inpatients diagnosed with BPD. Structural analysis revealed three symptom clusters that can explain symptomatology for a majority of the sample. BPD patients can be identified initially by a core factor and separated subsequently into several BPD subtypes based on the patients' remaining symptomatology. A hierarchical diagnostic scheme for delineating BPD subtypes is proposed, and the implications of these findings for a theoretical separation of several BPD subtypes are discussed.
