Which is an external variable influencing illness?

• A. Attitudes toward treatment.
• B. The visibility of symptoms.
• C. Their perceptions of symptoms.
• D. Cultural background.

Answer: (B)

External variables are factors outside the person that shape how illness is recognized and acted upon. The visibility of symptoms is external because it can be observed by others and serves as a concrete signal that prompts attention and response—people are more likely to notice, discuss, and seek care when symptoms are visible, and clinicians may respond sooner. Attitudes toward treatment and perceptions of symptoms are internal beliefs and interpretations, not external signals. Cultural background is part of the surrounding environment, but the most direct external cue among these options that influences illness recognition and action is how visible the symptoms are.
