Mixed Repeated Measures and Independent Measures One-Way ANOVA [SPSS]

#1
Hello,

I am trying to determine the best way to carry out my one-way ANOVA in SPSS.

I have three groups: Pre-Surgery, Post-Surgery, and Control.

Technically, the Pre- and Post-Surgery groups are repeated measures but the comparison to the control would be independent. How would I go about running this ANOVA to compare one variable (ie. HR) between these three groups. Mixed-model perhaps?

I can run a simple one-way ANOVA in SPSS but I would be ignoring that two of the groups contain the same people (Pre- and Post-Surgery).

Any direction would be helpful! Thanks!
