Which disorder might involve symptoms of panic in situations perceived as dangerous, leading to avoidance behavior?

The disorder that involves symptoms of panic in situations perceived as dangerous, leading to avoidance behavior, is indeed agoraphobia. This condition is characterized by an intense fear or anxiety about situations where escape might be difficult or help unavailable in the event of a panic attack. Individuals with agoraphobia often avoid being in crowded places, public transportation, or even leaving their homes, as they may fear experiencing panic attacks in those situations. This avoidance is a critical feature of the disorder, as it often leads to significant impairment in daily functioning.

In contrast, generalized anxiety disorder is characterized by persistent and excessive worry about a variety of different aspects of daily life, rather than specific panic-inducing situations. Obsessive-compulsive disorder revolves around unwanted and intrusive thoughts (obsessions) and ritualistic behaviors (compulsions) aimed at reducing anxiety, which is different from the panic symptoms and avoidance seen in agoraphobia. Dissociative identity disorder involves a fragmentation of personality and is not primarily focused on panic or avoidance related to perceived danger. Thus, agoraphobia is the most fitting disorder for the symptoms described in the question.
