MANCOVA and MANOVA Discussion > Repeated Measures MANCOVA?

I am trying to propose a pre-test, post-test longitudinal study with 1 I.V. (mentoring treatment) and 2 groups (treatment group and no-treatment/control group). There are 2 DVs (resilience and quality of life) and potentially 5 covariates (SES, education, physical health and controlling for pre-test measures of resilience and quality of life). I know this is MANCOVA because I have more than one DV and I am including covariates . Am I technically describing a one-way MANCOVA with repeated measures, or just a one-way MANCOVA? I am confused by everything I've read up to this point and have vacillated back and forth on this. Some sources I've read make me think repeated measures do not include control groups. I feel like I"m missing the big picture and have now read too much. HELP ME, please?

Thanks!

Hey JB,

You could actually use either a repeated measures analysis or a regular MANCOVA, depending on whether you want to examine change over time, or just group differences in posttest (controlling for pretest). The difference is examining both within-subjects and between-subjects of effects, or just examining between-subjects effects. Does that make sense?
