Purpose:  Summarize and appraise an article for bias and validity in a collaborative environment.

Instructions: Carefully read, summarize, and appraise your group’s assigned article.

  1. Identify and discuss the following:
    • what is known/not known about the topic and the gap in knowledge the study is intended to fill.
    • the research design, purpose of the study, and setting.
    • information about the sample:
      • method;
      • size;
      • inclusion/exclusion criteria,
      • attrition/loss to follow up/response rate, if any;
      • important characteristics of the sample.
  1. Appraise and debate the sampling methods. Consider the following questions:
    • Was the sampling method and inclusion/exclusion criteria adequate to reduce sampling bias?
    • Do the sample characteristics representative of the target population?
    • Was the sample size adequate?
    • Was there a decrease in sample size?  If so, did the researchers identify decreases early and attempt to reduce the impact?  Was a decrease, if any, adequately explained by the researchers?
    • How would you rate the quality of the sampling procedures and your confidence in drawing inferences to the target population?
