What is a key characteristic of persecutory delusions?

A key characteristic of persecutory delusions is the feeling that one is under constant scrutiny. This type of delusion involves an individual believing that they are being targeted or harmed by others, often leading to a heightened sense of paranoia. Those experiencing persecutory delusions may feel they are being watched, plotted against, or subjected to various forms of conspiracy, which can significantly impact their mental state and behavior.

The other options represent beliefs that do not align with the nature of persecutory delusions. For instance, believing one is universally loved would suggest a positive self-perception and lack of perceived threat, which contradicts the essence of being persecuted. Similarly, the notion of wanting to help others reflects altruism and a connection to others rather than the isolation and fear characteristic of persecution. Feelings of intense happiness and security are also contrary to the distress and anxiety experienced by those with persecutory delusions, as this condition typically engenders feelings of fear and vulnerability.
