Predicting treatment outcome analysis


New Member

I have 2 scales: the first one is for quality of life and the second one is symptom measure. I need to see if the quality of life predict treatment outcome (my symptom measure). I need to do an analysis with change of score (pre-post) , so i have change of scores for each one (same subjects) and I need to see if one can predict the other. What analysis do I do? Im using SPSS, would be great if i can have the full name of the analysis. Thanks

Statistics don't know directionality, that should be your content knowledge. So once you, decide which direction you are examing, tell us more about the variables and sample size.
