Intent: This assessment item focusses on critical appraisal of an epidemiological study published in a peer-reviewed journal article. The purpose of this assessment item is to give students an introduction to the appraisal of epidemiological studies.

Task details:

This assessment group task focuses on critical appraisal of an epidemiological study published in a peer-reviewed journal article. The purpose of this assessment item is to give students an introduction to the appraisal of epidemiological studies.

You have been assigned randomly to groups of four (or two groups of five) in Canvas. Your group will use a standard critical appraisal tool to assess a published research article against some of the items of the critical appraisal tool.

Task

You will need to use the correct JBI critical appraisal tool (https://joannabriggs.org/sites/default/files/2019-05/JBI_Critical_Appraisal-Checklist_for_Cohort_Studies2017_0.pdf (Links to an external site.)) and evaluate items 1 to 5.   Your group will need to include its assessment (ie Yes, No, Unclear or Not Applicable) for each item, and justify your group’s choice.  Also make sure you use appropriate epidemiological language.  For example, if you have concerns about measurement error, indicate what type of measurement error you have identified (eg, non-differential misclassification error) and the effects on the study’s results and validity.

In your answer, you will also need to answer the following questions:

  • what was the research question and is the study design the most appropriate?  
  • based on items 1 to 5 of the critical appraisal checklist, do you have any concerns about the internal validity of the study?

Make sure that you justify your answers appropriately. 

 Paper

The paper is ” Association between active commuting and incident cardiovascular disease, cancer, and mortality: prospective cohort study”. This is available here: https://www.bmj.com/content/bmj/357/bmj.j1456.full.pdf (Links to an external site.)

This will also be the paper for Assignment 4.

Group Work Details

As a group, you are to submit ONE document that details your evaluation of the published paper.  Consider using a Google document for this task that may assist your group to be on the same page.  Alternatively, you could submit a Word document that you have worked on together. You will be provided with a group space within Canvas through which you can collaborate.  You can use any other communication and collaborative tools you wish to complete this task. 

Marking criteria

  • 50% Explains relevant methodological issues, including bias, with available data
  • 40% Constructs critique and summary of issue, including a synthesised view and opinion from readings and class discussion
  • 10% Constructs coherent and cohesive information, including clarity of thought  depth of content, logical organisation and precision of arguments.

Intent: This assessment item focusses on critical appraisal of an epidemiological study published in a peer-reviewed journal article. The purpose of this assessment item is to give students a deeper understanding of the appraisal of epidemiological studies.

Task details:

You will continue to use a standard critical appraisal tool to assess a published research article against some of the items (different to those in assessment 3) of the critical appraisal tool. The published research article will be the same paper from assessment 3.

Task

You will need to use this tool (Links to an external site.) and evaluate items 6 to 10. (Note: you do not need to evaluate item 11 for this assessment.)  You will need to include its assessment (ie Yes, No, Unclear or Not Applicable) for each item, and justify your choice.  Also make sure you use appropriate epidemiological language and reasoning.  For example, if you have concerns about measurement error, indicate what type of measurement error you have identified (eg, non-differential misclassification error) and the effects on the study’s results and validity.

In your answer, you will also need to answer the following question:

  • based on items 1 to 10 of the critical appraisal checklist, do you have any concerns about the internal validity of the study

Make sure that you justify your answer appropriately.   You can base your answer for the final question on Assessment 3 and 4.
