Social phobia, or social anxiety disorder (SAD), is a disorder in which individuals experience overwhelming levels of fear in social situations and interactions. Individuals with social phobia tend to adopt strategic avoidance of social interactions, which makes it challenging for them to disclose themselves to others and reveal emotions. Self-disclosure is the key to foster intimate relationship, in which individuals can receive needed social supports. Close friendship and romantic relationship are two major sources for social supports, which have protective effect and play a crucial role in helping individuals with social phobia to cope with distress. Due to the profound impacts of the anxiety disorder, it has been found that late marriage or staying unmarried for the lifetime is prevailing among population with social phobia. This is problematic, because being unable to gain needed social supports from intimate ones further confines the social phobic in the loneliness and depression that they have been suffering from. In response to the problem, Sparrevohn and Rapee suggest that improving communication skill, particularly self-disclosure and emotional expression, should be included in future social phobia treatment, so the life quality of individuals with social phobia can be improved.
