Two main phases were carried out. First, the tool was developed based on expert opinion through three focus groups. Second, the tool was tested with exploratory factor analysis and confirmatory factor analysis in a sample of 458 postmenopausal women. The reliability of the developed Quality of Life Osteoporosis Scale-Nonvertebral Fractures (QoLOS-NVFX) was measured using Cronbach's α, maximal reliability (MR), composite reliability (CR), and average variance extracted (AVE). The QoLOS-NVFX resulted in a unidimensional scale with 23 items and showed good reliability, with a Cronbach's α of 0.94, an MR of 0.96, a CR of 0.96, and an AVE of 0.70. The QoLOS-NVFX shows good psychometric properties and can be used to assess the impact of NVFX on QoL in osteoporotic women. Furthermore, it can be easily used in clinical practice and research.Morning stiffness is known to exert a significant impact on functional ability, quality of life, and employment status. There is an increasing need for a valid, reliable tool to comprehensively assess morning stiffness. T
