Quality of care in nursing homes has begun to address the importance of resident choice in daily life, yet there are no published tools to teach nursing home staff how to offer such choice. In the current study, a formative assessment tool was developed that can provide staff with detailed and concrete feedback on how to realize resident choice. The tool was created and refined through 22 hours of ethnographic observation in two Veterans Health Administration Community Living Centers (CLCs), 22 hours of developmental testing in two CLCs, review by a modified Delphi panel, and use of an algorithm to assess its logical structure. The resulting Supporting Choice Observational Tool (SCOT) documents how choice is or is not offered and is or is not enabled within a singular staff-resident interaction. SCOT findings could be used in clinical teaching, quality improvement, or research efforts intent on enhancing nursing home resident quality of life. [Res Gerontol Nurs. 2017; 10(3):129-138.].
