Hi,
I am studying attitudes towards mental illness and whether they can be changed after an intervention. I will be using a mixed anova to calculate my results, however in order to do so i need to have a total attitude score (i think).

My attitude questionnaire consists of a measure of knowledge, stereotypes and social distance, all with differing scales.
Would i compute an attitude score for each section of my questionnaire and then combine it?

Would really appreciate the help,thanks!

Or would i carry out 3 seperate ANOVA's for each component of my questionnaire?
