In the field of health, many measurement scales have been developed and validated to evaluate the health status, psychological well-being and health-related quality of life. For the purpose of selecting a particular measurement scale or for developing new measurement scales (instruments), a coherent approach, including evaluation criteria, procedures, and evaluation techniques, is needed. Based on the analysis of the literature, the authors presented a set of criteria for evaluating the measurement scales and proposed a methodology for the development and validation of the measurement scales in the health domain. The methodology includes five steps: conceptualization, measure development, model specification, scale evaluation and refinement, scale validation. The evaluation criteria and methodology provide a general framework that can be used in academic research and clinical research to carry out empirical studies on the development and validation of measurement scales.
