Step 1: Understanding the Concept:
Delusions are false beliefs that are firmly held despite clear evidence to the contrary. They are a hallmark symptom of psychotic disorders. Different types of delusions have different themes.
Delusion of grandeur: Belief that one has exceptional abilities, wealth, or fame.
Delusion of reference: Belief that neutral events or comments have a special, personal meaning (e.g., a newscaster is sending a secret message).
Delusion of control: Belief that one's thoughts, feelings, or actions are being controlled by an external force.
Delusion of persecution: Belief that one is being plotted against, spied on, threatened, or deliberately victimized.
Step 2: Detailed Explanation:
Archit's beliefs all revolve around the central theme that others are trying to harm him. He believes he is being "spied on," that people are deliberately trying to get him "thrown out," and that they "tamper with his computer" to "attack his personal space." This is the classic presentation of a persecutory delusion.
Step 3: Final Answer:
The kind of delusion Archit is suffering from is a Delusion of persecution.
