Personality traits in social phobia

Abstract

SummaryThe purpose was to assess personality traits in subjects with a DSM-IV diagnosis of social phobia. Thirty-two subjects were administered the Structured Clinical Interview for DSM-IV for Axes I and II disorders (SCID I and II). Personality traits were assessed by means of the Karolinska Scales of Personality (KSP). Current and lifetime axis I co-morbidity was diagnosed in 28% and 53% of the subjects, respectively. In total, 59% had at least one personality disorder and 47% were diagnosed with an avoidant personality disorder.The social phobics scored significantly higher than a Swedish normative sample on the KSP measuring anxiety proneness, irritability, detachment, and indirect aggression but lower on the scales for socialisation and social desirability. The presence as compared to absence of avoidant personality disorder in the social phobics was associated with significantly higher psychic anxiety and inhibition of aggression. In addition, symptom severity was higher in social phobics with an avoidant personality disorder. Generally, the results support the view that social phobia and avoidant personality disorder reflect different aspects of a social anxiety spectrum.
