I'm doing a study with two groups of individuals, one who self harm and one who do not. Within these groups people are assigned to one of two interventions at random. These individuals, at the start of the experiment, also undergo a mood manipulation (all undergo the same negative one). This is then followed by the above intervention. I'm testing mood before the mood induction, after the mood induction and after the intervention. So it goes test mood 1 - mood manipulation - test mood 2 - intervention - test mood 3.
Firstly I need to do a few comparisons. I need to compare test 1 with test 3, test 1 with test 2, and test 2 with test 3. Is a repeated-measures t test the best way to go about this, or some kind of ANOVA? (and if so, which would be recommended?)

I would perform the chi-2 test in the three cases , if the samples are not too high or depending on your software a one-way ANOVa seems also suited to your study

Repeated-measures T is best. good luck!
