It’s normal to feel nervous in some social situations. For example, going on a date or giving a presentation may cause that feeling of butterflies in your stomach. Feelings of shyness or discomfort in certain situations aren’t necessarily signs of social anxiety disorder. Comfort levels in social situations vary, depending on personality traits and life experiences. Some people are naturally reserved and others are more outgoing. Contrary to everyday nervousness, social anxiety disorder induces fear, anxiety and avoidance that interfere with relationships, daily routines, work, school or other activities. Liebowitz Social Anxiety test assesses the way that social anxiety plays a role in your life across a variety of situations.
