What analysis should be used

I have a study where patients either get a treatment or no treatment. Each patient has a total of 4 visits. As part of each visit, they complete a quality of life questionnaire (reported as a number).

I am trying to determine if there is a difference in quality of life between the treatment vs no treatment group over time.

Is it correct to use a two way ANOVA test?
