Three studies were conducted using the interpersonal grid, a method for assessing perceptions of agentic and communal behavior based on the interpersonal circumplex. The 1st examined consistency across perceivers and convergence between perceiver and the perceived person. The 2nd examined whether responses to the interpersonal grid were sensitive to an experimental manipulation of portrayed agency and communion. The 3rd used the interpersonal grid in an event-contingent recording study. The reliability and validity of the measure were supported by findings demonstrating generalizability across perceivers, generalizability across perceptions of events involving the same person, convergence between perceiver and perceived person, and sensitivity to changes in levels of agency and communion. Applications of the interpersonal grid to clinical practice and research are described.
