The Neck Disability Index was developed by Vernon & Mior in 1991 and has since become one of the most widely used outcome measures for neck pain. It has demonstrated strong reliability and validity across various studies, with intraclass correlation coefficients (ICCs) ranging from 0.50 to 0.98.

The Neck Disability Index was developed by Dr. Howard Vernon and Dr. Silvano Mior in 1991. It was adapted from the Oswestry Disability Index (originally designed for low back pain) to specifically assess neck-related disability.
The tool has been validated in numerous studies and is widely used in clinical practice and research to measure patient outcomes and treatment effectiveness for neck pain conditions.
