In social services, if you want to compare the depression, anxiety, and stress levels of participants in two or more groups (meditation group, exercise group, control group) at different time points (pre-measurement, post-measurement, follow-up measurement) If there is a significant difference, you can use mixed analysis of variance. A mixed analysis of variance (ANOVA) can also help understand whether there is an interaction between these two factors (group, time) on the outcome variable (depression, anxiety, stress level).
