Which statement best characterizes internal variables?

• A. Perceptions of symptoms and the nature of their illness.
• B. Visibility of symptoms.
• C. Cultural background.
• D. Economic variables.

Answer: (A)

Internal variables are those that originate within the person and shape how they experience and interpret illness. Perceptions of symptoms and the nature of the illness are rooted in the individual’s beliefs, prior experiences, and cognitive appraisal, making them internal. The other options describe factors outside the person: visibility of symptoms is something that can be seen by others, while cultural background and economic variables are external social determinants that influence behavior from outside the individual. Understanding this helps explain why two people with the same objective signs may respond very differently based on their internal interpretations.
