- How were the survey respondents selected? What were the people who responded to the survey like (in terms of age, education, income, sex, etc.)? Did this group form a representative sample of all people who seek psychotherapeutic help?

- What did Seligman propose as the strongest points of the CR study? What did Jacobson and Christensen propose as the weakest?
- What is a retrospective study? What is wrong with retrospective studies? Was the CR study retrospetive?
