Hello,
If anyone could help me with this SPSS question I will be forever grateful.
I have three measures in my survey regarding drinking behavior and after conducting a chronbach alpha test they are essentially the same question asking the same thing (alpha= 0.582).
I would like to transform these three separate drinking behavior variables into one drinking behavior variable, however, they are all scaled differently (one is drinks in the past two weeks, one is drinks within two hours, and one is peak drinks in one occasion).
How can I make sure they are all scaled the same? I understand how to compute the three variables into one (using the addition function), but I am unsure how to weight the variables the same.
Help? Thank you!
