Fully one-third of the older adult population has foot problems that can lead to decreased mobility and independence. Foot problems such as corns, calluses, dry and cracking skin, and long or thick toenails can be managed through proper self-care, potentially increasing quality of life and functional status. Until recently, no tools existed to measure the presence and severity of nail and skin conditions that can be improved through self-management. The Foot Health Score, a 15-item, quantitative, provider assessment of skin and nail conditions amenable to self-management, had not undergone psychometric testing. Investigators refined the FHS tool and then evaluated content validity, discriminate validity, intra-rater reliability, and sensitivity to change.
