5. Improving intra-rater reliability is an important part of ensuring researcher reliability. What should a researcher be able to do in order to maintain consistency?

6. Describe what is meant by ’inter-rater’ reliability:

7. How can we improve inter-rater reliability?

8. Describe how we would improve face validity:

9. How is content validity assessed?

10. How do we know if a new test has concurrent validity?

The following questions are to be discussed with a learning partner. If you are having particular difficulty with a question, make a note and we’ll discuss it as a class issue:

11. What are the implications for a test that fails to show predictive validity. You might like to think about a mental disorder such as schizophrenia. Theoretically, if a person is diagnosed with a certain disorder, they should respond to treatments known to control their symptoms, but what if they don’t? Jot down some ideas.

12. How would we know if a test had temporal validity? Could we ever avoid era-dependence?

13. What would we have to do to be able to generalise the findings of our research to other population groups?

14. What are some of the problems faced by researchers trying to apply their findings to other contexts and situations outside of the research setting? Can we ever overcome this problem of ecological validity? From your knowledge of AS studies, give an example of a laboratory experiment that was supported by real-world research:

15. And finally, today we have learned that for our research to have scientific credibility it must be _ _ _ _ _ _ _ _ and _ _ _ _ _.
