This is my first post on here, I've recently started to learn about R and Rstudio.
There are a lot of things in my job that I think it will be useful for, but the thing that interests me the most at the minute is finding out if I can use it to create internally consistent item scales automatically.
Just to explain the situation that leads up to the analysis - I send out 16 slider questions which all aim to measure the same thing ("adaptability" for example) to a sample of 300 participants. When I get the data back, I use Cronbachs α to create two 6-item scales (Named "Scale A" and "Scale B"), hopefully with α>.7. Out of the 16 slider items, 8 of them will be measuring one facet of adaptability, and 8 of them will be measuring another facet, so i need to make sure that when i create my two slider scales, they both have 3 items from each facet. A single item can't appear in both scales (so for example, item 3 cant be in Scale A and Scale B).
Currently I do this with a mixture of Excel/Jamovi (My company is too cheap to buy SPSS) - is there a way that I can do the above actions using a single R script, so that I can input the 16 items and it will output for me two 6-item scales, consisting of 3 items from each facet, with no one item being used more than once, with the highest cronbachs α possible?
I'm not asking if someone can write this script for me, my question is more around "is this theoretically possible to do?" before i start trying to figure it out myself
