statistical test for psychology lab report

Hi guys! I'm working on a lab report, and am struggling to work out which statistical test I need to use for 2 of my research questions. For context, I have a continuous dependent variable, which is measured both at pre-test and during a 1 month follow up, and the independent variable has three levels compared alongside a control group

1) does the DV change from before the IV a 1-month followup after using the IV
2) does the type of IV influence how the DV scores change from pre-test to a 1 month follow-up

I've narrowed down my choices to ANOVA, but am struggling to understand which one would work specifically for either question. Any help would be really appreciated :smile:
