Original Question

Doering, L. V., Cross, R., Magsarili, M. C., Howitt, L. Y., & Cowan, M. J. (2007). Utility of observer-rated and self-report instruments for detecting major depression in women after cardiac surgery: a pilot study. American journal of critical care, 16(3), 260-269.‏ According to the previous article please answer the following questions: 1.) Begin with the abstract (summary) of the article. What was the purpose of the study? 2.) Why is this an important clinical issue? At this point you already know what the study is trying to do and why it matters. Great start! Now let’s dive into the article itself. Usually research articles begin with a literature review which establishes what the research already tells us and why the study is being done. Let’s see what role statistics can play in this portion of a research article. 3.) The authors begin by stating that “in adults with coronary artery disease (CAD) depression is common and dangerous.” How do the authors support this statement using statistics and what do these statistics mean? 4.) If depression after CABG surgery were a benign condition, it might not be particularly important to detect. For example, if the presence of depression was only associated with the type of toothpaste you selected the next day, the toothpaste company might want to fund the study but the National Institute of Health probably would not. Therefore, to strengthen the argument that depression in women after CABG surgery is an important issue to address the nurse researchers need to support that the outcomes associated with the presence of depression are significant. How is statistics used to do this? 5.) Now the authors go on to use statistics in another way. They already told us there are few measures of depression in women after CABG surgery but there are reports of rates in a “similar population,” those with coronary heart disease or heart failure. Do they report a difference in the gender specific prevalence rates of depression in these women? 6.) The researchers then present information about the measurement tools they wish to examine in this study. They already have a valid and reliable tool, the structured diagnostic interview, to detect depression. What do we know about this tool from this description? 7.) Why not just keep using this tool if we already know it works? 8.) What are the advantages and disadvantages of the self report and observer instruments used to detect depression? 9.) What test is the “gold standard” (the one that will be used to establish that depression exists and test if the other measures are able to detect it)? 10.) Now let’s look at the actual design of the study. What type of study design was utilized?
