Hello.
The panel advised me to use a sequential exploratory design for scale development. However, the construct that I will be studying is from the 70s. Also, there are existing scales about it.
My question is: should I write an RRL before conducting interviews? Aside from that, if RRL is advisable, how should it guide my interview questions?
Thank you.
Your answer is more than yes or now. First, most research institutions and grants require a review of the literature. Secondly, depending on one's aims, not all qualitative methodologies push for a review of the literature first. Go back to your aims, purpose, and research questions. Thirdly, most psychological organizations, like the APA, state that an instrument is valid until it no longer is. That is a generic way of stating that over time, as society and the sociocultural change, instruments sometimes no longer capture what they purport to do. Every instrument can generally profit from examining validity and reliability with the particular target population and sample. Many researchers neither have time nor understand that validity/reliability is not universal/static/not-always-transferable.
A review of related literature is hardly the same as a sequential exploratory design, because the latter requires the collection of data.
If you have existing scales that are adequate for you purpose, then that should be sufficient.
I understood your question very differently than David Morgan. Were you suggesting your literature review would be your qualitative component? I presumed your interviews (qualitative) were phase 1, and being exploratory, that the scale (quantitative) would be phase 2. Nevertheless, it is never unwise to examine each scale for reliability and validity with your sample and context. Please clarify.
