- The person recognizes that the fear is excessive or unreasonable.
- The phobic situation(s) is avoided or else is endured with intense anxiety or distress.
- The avoidance, anxious anticipation, or distress in the feared situation(s) interferes significantly with the person's normal routine, occupational (or academic) functioning, or social activities or relationships, or there is marked distress about having the phobia.
Social Phobia (Social Anxiety Disorder)
- Marked and persistent fear (at least 6 months) of one or more social or performance situations in which the person is exposed to unfamiliar people or to possible scrutiny by others. The individual fears that he or she will act in a way (or show anxiety symptoms) that will be humiliating or embarrassing.
- Exposure to the feared social situation almost invariably provokes anxiety.
- The person recognizes that the fear is excessive or unreasonable.
- The feared social or performance situations are avoided or else are endured with intense anxiety or distress.

Either obsessions or compulsions:
- Recurrent and persistent thoughts, impulses, or images that are experienced, at some time during the disturbance, as intrusive and inappropriate and that cause marked anxiety or distress.
- The thoughts, impulses, or images are not simply excessive worries about real-life problems.

- the person recognizes that the obsessional thoughts, impulses, or images are a product of his or her own mind.
- Repetitive behaviors (e.g., hand washing, ordering, checking) or mental acts (e.g., praying, counting, repeating words silently) that the person feels driven to perform in response to an obsession, or according to rules that must be applied rigidly.
- The behaviors or mental acts are aimed at preventing or reducing distress or preventing some dreaded event or situation; however, these behaviors or mental acts either are not connected in a realistic way with what they are designed to neutralize or prevent or are clearly excessive.
- At some point during the course of the disorder, the person has recognized that the obsessions or compulsions are excessive or unreasonable.
