Sidney Blatt's Object Relations Inventory: Contributions and Future Directions

In this article, we provide a historical overview of the Object Relations Inventory (ORI) and related methods for the assessment of object relations constructed by Sidney Blatt and colleagues (e.g., Blatt, Bers, Blatt, Wein, Chevron, Diamond, Kaslow, Coonerty, & Blatt, 1990 Diamond, D., Kaslow, N., Coonerty, S., & Blatt, S. J. (1990). Change in separation-individuation and intersubjectivity in long-term treatment. Psychoanalytic Psychology, 7, 363–397.Crossref , Google Scholar). We clarify terminology that has been used inconsistently in the literature, especially by way of differentiating the methods used to collect descriptions of significant figures, such as the ORI and its predecessor, the Parental Description (PD) task, and the rating scales that Blatt and colleagues constructed to rate those descriptions. We provide a tabular summary of empirical studies of the measure and offer a critical review of those aspects of the instrument that require further empirical investigation and methodological rigor.
