It is known that through optimal sample definitions and data collection, test norms are not absolute. With this they can change with time or with a different norm group. Knowing this, I need help with developing a description of the information that can be anticipated when collecting through looking at the proposed instrument when assessing childhood aggression. Then explain how one would optimally define the given sample and collect the data if allotted UNLIMITED resources (The key phrase is unlimited resources). Finally, explain advantages and disadvantages of the chosen data collection method. Please also include at least one journal reference.
First of all, I'd like to point you to the Mental Measurements Yearbook. It is the very best resource on finding specific psychological tests and assessments for any area you are interested in researching. It helped me a lot when I was in my masters and PhD programs. I used the print version from my professors, but I did a little digging and was able to find an online version for you. Buros is the company that produces the MMY; here is their website: http://buros.unl.edu/buros/jsp/search.jsp. If you go to that site, you should be able to search for instruments and filter out for aggression and child vs. adult versions. I was given a question similar to yours when I was a first year PhD student: I had to use the Mental Measurements Yearbook to find instruments to assess for childhood anxiety, and I had to write out what kind of data could be collected based on the instrument. In regards to your question as to what type of information can be collected from an assessment tool, I would think there would be general ...
