1. The problem the authors identified as underlying this research.

2. The purpose of this study?

3. Which theory(ies), if any, did the authors use to support their study? How did the authors use theory?

4. On what basis did the authors justify the need for their study? i.e., what was the rationale for conducting this study?

5. To what extent were the research questions supported by the literature review?

6. What was the target population for the study? What inclusion and exclusion criteria, if any, did the authors use to define their population?

7. What were the characteristics of the accessible population and/or sampling frame? Discuss the extent to which the accessible population/sampling frame appeared to provide adequate "coverage" of the target population?

8. What type of sampling procedure did the authors use for obtaining participants? What information in the article suggested this type of sampling?

9. What was the sample size in the current study and was the sample size sufficient to obtain adequate statistical power for all of the statistical analyses? Describe the evidence you're using to support your response regarding sufficiency of the sample size.

10. a. What broad type of research design did the authors use (true experimental, quasi-experimental, or non-experimental)

b. What information in the article suggests this was the design?

c. What specific type of research design did the authors use (within the broad category you identified above)? Briefly explain what information in the article suggests this specific design.

11. Discuss least three possible threats to internal validity or extraneous variables that might have affected the results of this study. For each threat/extraneous variable, indicate how the threat/variable might have affected the results given that it was not controlled in the current study.

12. Discuss at least two possible threats to external validity in this study and explain how these aspects of the study posed external validity threats. These threats should represent aspects of the study not already discussed above.

13. If you were extending the research by conducting a new study on the topic addressed in the article you reviewed, what are at least two changes you could make in an attempt to address the external validity threats you identified in question 12?
