Hello again. I think the analyses worked, but I am just hoping to double-check that the model is doing what I think it is doing (copied again below). Since I have anxiety at time one (T1) and time two (T2) for each subject, is this model testing change in anxiety T2-T1 or is it T2/T1 or something else? We are hoping to test whether increases in functional connectivity are associated with decreases in anxiety over time.
Thank you again.
