The current study examined aspects of communication and intimacy between people with social phobia and their romantic partners. Forty-eight individuals with social phobia and 58 community controls completed a series of questionnaires to measure self-disclosure, emotional expression and levels of intimacy within their romantic relationships. Participants with social phobia reported less emotional expression, self-disclosure and intimacy than controls, even after controlling for a diagnosis of mood disorder. The group differences did not differ significantly by gender. A continuous measure of social anxiety also correlated significantly with the three relationship measures and these associations held for emotional expression and self-disclosure after controlling for levels of dysphoria. People with social phobia report reduced quality within their romantic relationships, which may have implications for impairment, social support and ultimately maintenance of the disorder.
