Hi I am planning to conduct a within subject study: where we are trying to test the effectiveness of an intervention: the study will test participants on 3 occasions i.e. Time 1 (baseline without the intervention)
Time 2 (with the intervention)
Time 3(with the intervention)
I am testing the (i)Parental distress using the subscale from (PSI short form)
(ii) Perceived stress scale (PSS)
(iii) Brief COPE
I want to see if the intervention affects the stress levels and if there is a relationship between coping and stress. What would be the best analysis to conduct to find this out?
Any help will be much appreciated!!
