Abstract
The companion article by the Group for the Advancement of Psychiatry (GAP) Committee on the Family (see p. 155, this issue) describes the development of the Global Assessment of Relational Functioning (GARF) scale. The present study evaluated the reliability and concurrent validity of a manualized version of the GARF in recently episodic bipolar patients (N = 73) participating with family members in laboratory interaction tasks. The GARF was applied with high reliability by raters with little clinical experience. GARF ratings discriminated between families rated high and low in expressed emotion, with families rated as high in emotional overinvolvement showing the lowest relational functioning scores. GARF scores also correlated with affective negativity scores derived from the interactional task-based affective style and coping style coding systems. However, relational ratings were independent of levels of concurrent symptoms or illness chronicity among individual patients. GARF ratings may inform the treatment plans for patients with psychiatric disorders, but the optimal methods of data collection and rater training must be determined.
