Measurement Tools/Instruments

In this DB, you will continue with the example in Module One Discussion Board.

For example (this is just an example), the researcher decides to include temperature as a dependent variable (to support CAUTI) and needs to identify a measurement method for temperature. The researcher decides to use Bard Foley Catheters (Series 400 Temperature Sensing). The author would Include a description of Bard Temperature Sensing Foley Catheters (400 Series) from literature.

The researcher is also interested in anxiety and will include anxiety in their study as a secondary research question. What is the strength of the relationship between the length of foley catheter insertion and anxiety in patients cared for in the critical care environment? The researcher will measure anxiety using the Beck Anxiety Inventory. The tool is a  21-question multiple-choice

 in children and adults. The tool has shown high internal consistency (α = .92) and test-retest reliability over 1 week, r(81) = .75. The BAI discriminated anxious diagnostic groups (panic disorder, generalized anxiety disorder, etc.) from non-anxious diagnostic groups (major depression, dysthymic disorder, etc.). In addition, the BAI was moderately correlated with the revised Hamilton Anxiety Rating Scale, r(150) = .51, and was only mildly correlated with the revised Hamilton Depression Rating Scale, r(153) = .25. (PsycINFO Database Record (c) 2016). The author would also note the reliability and validity of the instruments used in the study. 

Physiological tool: Bard Temperature Sensing Foley Catheter (400 Series)  

Psychosocial tool: Beck Anxiety Inventory 

For this DB, you will identify both a psychosocial AND a physiological measurement tool that could be used to measure a concept in your area of interest. Post a brief description of the two types of measurement tools in your group discussion forum (one paragraph each). Identify support in the literature (can be from your articles you are using for this DB post) for the reliability and validity of the two types of tools and post a summary of the support (one paragraph) in your group discussion forum. Criteria for the physiological critique can be found in Gray, Grove, and Sutherland (2018) Chapter 16. Provide citations. Reply to two peers. The initial post is due on Wednesday and peer replies on Saturday.

GUIDELINES

To receive full credit, your original post should include all elements requested in the prompt (prompt may have multiple parts and/or require an article to be attached). Responses to the prompt should be made directly in the discussion forum (not as an attachment). All posts (original and replies) should be substantive and contribute to the understanding of the topic. Your response can support the view of the other person, lend a different viewpoint, or provide additional information. In addition, peer response can be a question which, if answered, would improve upon the other student’s original idea. Provide a rationale for your views and provide a citation. No credit will be given for peer responses such as “good job” or “I agree.”

Your online participation grade for each week has three parts: 60% for the original post, 20% for your first peer reply, and 20% for your second peer response. Responses should be made to peers who have not already received two peer responses so that everyone receives two responses.
