study 1: one sample, repeated measures design

1 IV (intervention: yes or no)

1 within group IV (time point post-intervention@ month 1, month 2, month 3, -6)

2 dependent variables: medication adherence and disease state-specific lab

2 covariates: baseline medication adherence and disease state-specific lab (pre-intervention)

For study #1, is MANCOVA appropriate? If so, what are the assumptions and how can I test them?

study 2: two samples, repeated measures design

1 between-group IV (control and intervention)

1 within-group IV (time point post-intervention@ month 1, month 2, month 3, -6)

2 dependent variables: medication adherence and disease state-specific lab

2 covariates: baseline medication adherence and disease state-specific lab (pre-intervention)

For study #2, is MANOVA appropriate? If so, what are the assumptions and how can I test them?
