Numerical Rating Scale (NRS) is set of single items designed to assess overall domains of Quality of Life (QoL), including emtional/mental/physical well-being, social activity and sleep quality. NRS items have 11 response options with scores from 0 to 10, which indicate the best possible or worst possible QoL in each domain. The NRS item for sleep quality was reverse-coded to link to PROMIS Sleep Disturbance.
