    How to do a Validation Study?

    My professor has asked me to do a validation study but I have never done one before and don't know what methodology or statistics to use. Basically the original study took a personality assessment with 27 scales and compared it to an ADHD assessment. A stepwise regression identified six scales that were responsible for a large proportion of variance in the ADHD assessment. A MANOVA identified six subscales that significantly differed between those with ADHD and those without.

    I was asked to validate one or both of the original statistics. Any suggestions on methodology or statistical analyses? Or any validation studies you can recommend I read that may be similar?

    are you familiar with factor analysis/structural equation modeling?

    it would also be helpful if you're familiar with "The Standards for Educational and Psychological Testing" (aka the Standards). everything that has to do with validity and validation there is in the first chapter
