<OpenstaxParagraph>
	<OpenstaxTerm>Social anxiety disorder</OpenstaxTerm> (formerly called social phobia) is characterized by extreme and persistent fear or anxiety and avoidance of social situations in which the person could potentially be evaluated negatively by others (APA, 2013). As with specific phobias, social anxiety disorder is common in the United States; a little over 12% of all Americans experience social anxiety disorder during their lifetime (Kessler et al., 2005).
</OpenstaxParagraph>
<OpenstaxParagraph>
	The heart of the fear and anxiety in social anxiety disorder is the person’s concern that they may act in a humiliating or embarrassing way, such as appearing foolish, showing symptoms of anxiety (blushing), or doing or saying something that might lead to rejection (such as offending others). The kinds of social situations in which individuals with social anxiety disorder usually have problems include public speaking, having a conversation, meeting strangers, eating in restaurants, and, in some cases, using public restrooms. Although many people become anxious in social situations like public speaking, the fear, anxiety, and avoidance experienced in social anxiety disorder are highly distressing and lead to serious impairments in life. Adults with this disorder are more likely to experience lower educational attainment and lower earnings (Katzelnick et al., 2001), perform more poorly at work and are more likely to be unemployed (Moitra, Beard, Weisberg, &amp; Keller, 2011), and report greater dissatisfaction with their family lives, friends, leisure activities, and income (Stein &amp; Kean, 2000).
</OpenstaxParagraph>
<OpenstaxParagraph>
	When people with social anxiety disorder are unable to avoid situations that provoke anxiety, they typically perform <OpenstaxTerm>safety behaviors</OpenstaxTerm>: mental or behavioral acts that reduce anxiety in social situations by reducing the chance of negative social outcomes. Safety behaviors include avoiding eye contact, rehearsing sentences before speaking, talking only briefly, and not talking about oneself (Alden &amp; Bieling, 1998). Other examples of safety behaviors include the following (Marker, 2013):
</OpenstaxParagraph>
<OpenstaxUl>
	<OpenstaxLi>
		assuming roles in social situations that minimize interaction with others (e.g., taking pictures, setting up equipment, or helping prepare food)
	</OpenstaxLi>
	<OpenstaxLi>
		asking people many questions to keep the focus off of oneself
	</OpenstaxLi>
	<OpenstaxLi>
		selecting a position to avoid scrutiny or contact with others (sitting in the back of the room)
	</OpenstaxLi>
	<OpenstaxLi>
		wearing bland, neutral clothes to avoid drawing attention to oneself
	</OpenstaxLi>
	<OpenstaxLi>
		avoiding substances or activities that might cause anxiety symptoms (such as caffeine, warm clothing, and physical exercise)
	</OpenstaxLi>
</OpenstaxUl>
<OpenstaxParagraph>
	Although these behaviors are intended to prevent the person with social anxiety disorder from doing something awkward that might draw criticism, these actions usually exacerbate the problem because they do not allow the individual to disconfirm their negative beliefs, often eliciting rejection and other negative reactions from others (Alden &amp; Bieling, 1998).
</OpenstaxParagraph>
<OpenstaxParagraph>
	People with social anxiety disorder may resort to self-medication, such as drinking alcohol, as a means to avert the anxiety symptoms they experience in social situations (Battista &amp; Kocovski, 2010). The use of alcohol when faced with such situations may become negatively reinforcing: encouraging individuals with social anxiety disorder to turn to the substance whenever they experience anxiety symptoms. The tendency to use alcohol as a coping mechanism for social anxiety, however, can come with a hefty price tag: a number of large scale studies have reported a high rate of comorbidity between social anxiety disorder and alcohol use disorder (Morris, Stewart, &amp; Ham, 2005).
</OpenstaxParagraph>
<OpenstaxParagraph>
	As with specific phobias, it is highly probable that the fears inherent to social anxiety disorder can develop through conditioning experiences. For example, a child who is subjected to early unpleasant social experiences (e.g., bullying at school) may develop negative social images of herself that become activated later in anxiety-provoking situations (Hackmann, Clark, &amp; McManus, 2000). Indeed, one study reported that 92% of a sample of adults with social anxiety disorder reported a history of severe teasing in childhood, compared to only 35% of a sample of adults with panic disorder (McCabe, Antony, Summerfeldt, Liss, &amp; Swinson, 2003).
</OpenstaxParagraph>
<OpenstaxParagraph>
	One of the most well-established risk factors for developing social anxiety disorder is behavioral inhibition (Clauss &amp; Blackford, 2012). Behavioral inhibition is thought to be an inherited trait, and it is characterized by a consistent tendency to show fear and restraint when presented with unfamiliar people or situations (Kagan, Reznick, &amp; Snidman, 1988). Behavioral inhibition is displayed very early in life; behaviorally inhibited toddlers and children respond with great caution and restraint in unfamiliar situations, and they are often timid, fearful, and shy around unfamiliar people (Fox, Henderson, Marshall, Nichols, &amp; Ghera, 2005). A recent statistical review of studies demonstrated that behavioral inhibition was associated with more than a sevenfold increase in the risk of development of social anxiety disorder, demonstrating that behavioral inhibition is a major risk factor for the disorder (Clauss &amp; Blackford, 2012).
