Hi all,

I am undertaking a thesis and it has been a long while since I've been at university (and using Stata!) and am looking for some clarification:

My experiment is a within-subjects design whereby participants watch 4 consecutive videos (2 different conditions) and rate the videos on 3 measures after each video (Attitudes towards help-seeking, Trivialisation and Stigma - all continuous). Participants also undertake a big 5 measure of personality (which includes 5+1 continuous predictors)

The experiment is really: 6x personality IV's x 2x condition IV levels x 3 DV measures.

My plan was to run 3 separate ANCOVA's (as I am only really interested in 3 of the personality measures) controlling for gender and source credibility but am wondering if this is the best analysis to use.

As a mature-aged student, this is confusing the heck out of me and for some reason I'm unable to wrap my head around the interaction syntax.

Any help is greatly appreciated. Thanks in advance
