I have conducted a study where participants are split between two groups (treatment and control). I want to measure changes in depression and sleep disturbance pre and post-test (before and after intervention). I want to see interactions between-subjects for depression and sleep. I also want to see interactions within-subjects before and after treatment for both depression and sleep.What analysis would be appropriate? Would I do multiple analysis?
Depression Sleep
Treatment Before After Before After
Control Before After Before After

Treatment Before After Before After
Control Before After Before After
