Which instrument is most appropriate for assessing general health status across multiple domains?

• A. Tegner
• B. SF-36
• C. LEFS
• D. ACL-RSI

Answer: (B)

Assessing general health across multiple domains needs a generic, multi-domain instrument rather than a tool tied to a single aspect of health. The SF-36 fits this purpose because it’s a widely used generic health survey that covers eight domains of health status: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health. It also provides physical and mental component summary scores, enabling broad comparisons across populations and over time without being tied to a specific condition or knee function. The other instruments are more specialized: Tegner focuses on activity level in knee-related sports, not overall health; the Lower Extremity Functional Scale targets function of the lower limb in daily activities, a domain-specific physical measure; and the ACL-RSI assesses psychological readiness to return to sport after ACL injury, which is a focused emotional/cognitive domain. Thus, SF-36 is the best choice for evaluating general health status across multiple domains.
