Questions: What belief(s) and/or behavior(s) contribute to Social Anxiety Disorder? - Viewing the self as socially unskilled - Avoiding social situations - Unrealistically high standards for performance in social situations - All of the above

The answer is D: All of the above.

Explanation for each option:

1. Viewing the self as socially unskilled: This belief can contribute to Social Anxiety Disorder (SAD) because individuals may perceive themselves as inadequate or incapable in social interactions. This negative self-view can lead to increased anxiety and avoidance of social situations, reinforcing the disorder.

2. Avoiding social situations: Avoidance is a common behavior in individuals with SAD. By avoiding social interactions, they temporarily reduce their anxiety, but this behavior prevents them from learning that their fears may be unfounded or manageable. Over time, avoidance can exacerbate the disorder by reinforcing the belief that social situations are threatening.

3. Unrealistically high standards for performance in social situations: People with SAD often set excessively high standards for themselves in social contexts, fearing judgment or rejection if they do not meet these standards. This can lead to heightened anxiety and self-criticism, contributing to the maintenance of the disorder.

Each of these beliefs and behaviors plays a role in the development and maintenance of Social Anxiety Disorder, making option D the most comprehensive answer.
