Help needed for beginner using SPSS please!

#1
I am a psychology student, I have conducted an experiment. It involved 3 groups;
group 1- viewed neutral stimuli
group 2- viewed enhanced stimuli
group 2- viewed real stimuli

There were 25 participants in each group. They completed a Self Esteem Questionnaire before and after being shown the stimuli and a Body Shape Questionnaire before and after being shown the stimuli.

I have put the data in with the variables as: Group (nominal), SEQ score before (ordinal), SEQ after(ordinal), BSQ before (ordinal) and BSQ (after). I have given the group variable values according to the group.

I think I need to perform a 3 way ANOVA? But I am not sure.
Please could some one give me some advice, talk me through the process on SPSS.

Thank you!

That depends on your research question. You did not mention any.

I often read that Andy Field's SPSS book is very good for beginners.

Kind regards

Hi thank you I will have a look at the book you have suggested to get my head round SPSS some more!

I have two Hypothesis:

H1- There will be a significant decrease in SEQ and BSQ scores when participants view airbrushed/enhanced images.

H2- There will be a significant increase in SEQ and BSQ scores when participants view positive/real images of beauty.

So I am looking for the differences between the scores for each group.

So you just have 1 hypothesis concerning group 2 and 1 hypothesis
concerning group 3? These hypotheses could be tested using simple
pre-post comparisons (dependent samples t-test or Wilcoxon signed
rank test). But why did you think you'd need a 3way (three-factorial?)
ANOVA? And why did you include a "neutral stimulus" group, if none
of your research questions/hypotheses concern that group?

Kind regards
