This article reports two studies. The first attempted to define stable dimensions within the Stuttering Severity (SS) scale. A factor analysis of correlations among its 64 items defined four factor-based subscales, and three additional subscales were developed rationally. Relationships among these seven subscales suggested the existence of two major dimensions. The second study investigated the relationship of the seven subscales to psychopathology. Correlations were obtained among the subscales and MMPI scales for 69 subjects, and were subjected to a second factor analysis. The MMPI scales and the SS subscales clearly loaded on separate factors, indicating little relationship between dimensions of stuttering and psychopathology as defined by MMPI scores. The second analysis also supported the previous identification of two general dimensions for stuttering. Items were selected for two final scales to represent these dimensions, labeled behavior (22 items) and sensitivity (20 items). Norms were developed for them and also for the full 64-item SS scale.
