I'm analyzing data from a study, where Multidimensional Scale of Perceived Social Support (MSPSS) is included. It seems that there are scores recorded for 12 items, but I don't know how to calculate the score. Do I just take the mean of 12 scores?
I searched online, and found the following statement:
The MSPSS can be scored to measure perceived support from family, friends, and a significant other, or global perceived support.
I'm wondering if that means rating from different individuals. Since I only have one set of scores for each subjects, can I assume that's "global perceived support"?
