Hi,

I have a question regarding reliability test and hope that I can get some
help from this forum.

I administered a single-item likert-scale instrument several times within
the week of my experimental study. I want to calculate the reliabiity of
this instrument (I think it should test-retest reliability. Please correct
me if I'm wrong) in my study, but I'm not sure how to do that in SPSS since
the instrument was used more than twice (so a bivariate correlation test
will not work?). Anyone can shed some lights? Thank you very much!

Best,
Huang
