Which psychological concept is characterized by beliefs tied to personal significance in everyday life?

The concept of reference delusion involves the belief that ordinary events, objects, or the behavior of others hold personal significance or specific messages directed at the individual. This typically manifests in a way where the person perceives these everyday occurrences as being directly related to them, often with no basis in reality. For instance, someone might believe that a news broadcast is discussing their life or that strangers are speaking about them when they are not.

This concept is distinct from delusional disorder, which encompasses a broader range of false beliefs that are not limited to personal significance. In compulsive disorders and obsessive-compulsive disorder, the focus is not on the personal significance of external events but rather on intrusive thoughts and the behaviors that individuals feel compelled to perform to alleviate anxiety. Hence, reference delusion specifically captures the essence of linking everyday phenomena to personal meaning, making it the correct choice in this context.
