This study established standard reference values for three questionnaires that measure different types of health concerns: body image worries, health anxiety, and fatigue/weakness. Researchers compared how 648 healthy people and 823 patients with these conditions answered the questionnaires, so doctors now have clear cutoff scores to help decide if treatments are working and when to adjust or stop therapy.
