answer the following discussion board question

NOTE: As you work on the following items below, you may want to refer back to Appendix B in Engel and Schutt.

Based upon your reading of Pomeroy, Kiam, and Abel (1999; see the attached .pdf), address the following:

Section I: Critique of the Article’s Introduction/Literature Review (p. 171–174)

In your own words, what was the overall purpose of Pomeroy et al.’s research study? Was the literature review adequate and relevant? That is, did it lend support to the current study? If yes, how so? If no, speak to the limitations/weaknesses of the literature review and provide recommendations for how it could be strengthened.

Section II: Critique of the Article’s Methodology (p. 174–179)

What type of sampling approach was used in general (re: probability or non–probability) and specifically (e.g., simple random, stratified random, etc.)? Identify the research design. That is, would you classify this as a pre–experimental, quasi–experimental, or experimental study? How did you come to that conclusion? Did Pomeroy et al. sufficiently inform their audience of potential threats to the internal and/or external validity of their study that stem from the research design? Briefly explain your response.

Section III: Critique of the Article’s Discussion (p. 182–185)

Did Pomeroy et al. adequately acknowledge the strengths and limitations of their study? Briefly explain your response. Are there other strengths and limitations that were not identified? Be specific. If you were to build upon this study, discuss how you would handle the sampling strategy and research design in order to enhance causality (re: strengthen enhance your ability to make causal inferences that the intervention is responsible for the outcomes).

NOTE: As you review the article, back up your critique by citing the relevant page(s) from the article. Please note, initial posts should be between 300 and 500 words. As applicable, relate and support your initial post with what you learned from the course materials for this week and any other resources you want to share (e.g., from prior courses), using standard APA citations. In addition to starting a discussion by making your initial post, you are required to read the postings of fellow students and respond to at least two other initial posts. Your responses should elaborate on the initial postings of your colleagues (e.g., exchange ideas, debate points, and/or add to their ideas) and should be approximately 150 words each.
