Factor analysis of the Bell Object Relations Inventory items produced four subscales interpreted to be underlying dimensions of object relations. Replication factor analysis confirmed the factor structure. Subscales had high internal consistency and were free of age, sex, or social desirability response bias. Subscales had low intercorrelations with Brief Psychiatric Rating Scale (BPRS) sum scores, Global Assessment Scale scores, and most BPRS symptoms. Subscales appear to represent common features of personality and to sample a domain that is distinct from symptomatology, but related to variations in psychopathology. Percentage of high scoring subjects and subscale mean values are compared for seven criterion groups. High scores were least frequent among community active adults and most frequent among borderlines. Selected findings from the group comparisons are discussed to illustrate the potential of the instrument for empirical examination of theoretical assumptions about the object relations ego function and its components.
