I am working in the area of digital finance, and i want to develop a scale, but there is no pre existing scale for the concerned variable. All the existing measures are taken from national surveys items. Moreover, there are varied conceptualizations of the concept. I have developed my own conceptual definition using two theoretical models. Now, i am developing my initial pool of items but i facing problems as the concept has not been studied in the digital context. Please suggest some way forward, and any reference. Also, i want to know is it valid if i am developing a scale using theoretical background, and on the basis of those theories i am adding dimensions into my proposed scale. Because usually papers on scale development does not mention any theory. Please guide me.
One possibility is to build in reactions and suggestions from your potential participants. For example, one common way of generating item content is through focus groups. Another is to use Delphi techniques.
But if you need to rely entirely on prior theory, plus your own insights, then what you need to do is operationalize those theories into measurable variables. In terms of the bigger picture, you can frame your own additions to the existing theory as testable hypotheses. In particular, you could test whether your new ideas create additional explained variance, above and beyond the measures from prior theory.
You can generate new scale through inductive and deductive approach.
