Hey guys,

I’m new here so I hope I on the right website here.

I am trying to prepare my data for analysis, and am not quite sure in which form I have to sort them.

I am doing a SEM analysis of dyads (APIMextendedMediation) by using an existing dataset. Now for every variable (x, y, m), I have several measures as the participants filled out questionnaires two times a day for 5 days.

So now I wanna see if same day x predicts same evening m which then predicts next-day y.

As I have several measures of each variable, I would like to use that data so that I have more power.

So I will have several seperate cases/case sets per person (Day 1 x, Day 1 m, Day 2 y; Day 2 x, Day 2 m, Day 3 y, Day 3 x, Day 3 m, Day 4 y, and so on…)

Like this, I will have 4 times more data than the actual sample.

My question now: Is this even “allowed”??? How do I have to state this in a paper, or what is this procedure even called?

And most importantly: how do I display this in my database? Will every separate “data set” be its own case/row, or do I do rows by person? I will use SPSS for the analysis, and I don’t really know how it will understand which variable is predicted by which one when I put everything in one single model together.

Hope my description makes at least some sense. I am very grateful about your answers!!
