What type of delusion is the client experiencing if they believe their internal organs have turned to stone?

The belief that one's internal organs have turned to stone is classified as a somatic delusion. Somatic delusions involve a person believing that they have a physical illness or medical condition, despite medical evidence to the contrary. This type of delusion focuses on the body's sensations or functions, often leading individuals to feel that something is drastically wrong with their physical state. In this case, the individual perceives a significant and unusual transformation of their internal organs, which aligns with the characteristics of somatic delusions.

Paranoid delusions typically involve beliefs that one is being persecuted or conspired against, often causing significant anxiety. Grandiose delusions involve an inflated sense of self-importance or power, such as believing one has exceptional abilities or is a famous figure. Reference delusions include thoughts that common elements of the environment are directly related to oneself, such as believing that a song on the radio is specifically targeting them. These types of delusions differ fundamentally from the somatic delusion presented in the scenario, reinforcing why the belief in one’s organs turning to stone is classified as somatic.
