Which term defines a disability factor with external etiology?

• A. Exogenous Factors
• B. Endogenous Factors
• C. Intrinsic Factors
• D. Internal Factors

Answer: (A)

The concept being tested is origin of disability factors—whether they come from outside or inside the individual. A factor with external etiology is described by exogenous factors. “Exogenous” means outward or external to the person, such as environmental influences, accidents, or external exposures that contribute to disability. In contrast, endogenous or intrinsic factors originate from within the person, and internal factors is a general internal-origin term. Since the question specifies an external source, exogenous factors best fit.
