Assessment of sensitivity to interpersonal stress in stutterers.
The Willoughby Personality Schedule-R was administered to adult male Yugoslav stutterers who were not yet in treatment. Internal consistency of the WPS-R was assessed by computing item-scale score correlations. Twenty-two of 25 items were significantly correlated with WPS-R total score. Confirmatory factor analysis revealed three separate and reliable dimensions: Social Isolation (ssca .85), Social Confidence (ssca .74), and Social Sensitivity (ssca = .62), that were identical to those previously found for American stutterers. Although WPS-R scores were unrelated to several measures of stuttering severity, analysis of extreme scores suggested support for the hypothesis that general anxiety moderates stuttering severity. Overall the results are consistent with the contention that hypersensitivity to interpersonal stress is manifested in stutterers as general anxiety, which is better conceptualized as occurring along a continuum than as reflecting generic "overwhelming anxiety" in stutterers.
