measuring the effectiveness of the intervention

This week, we are examining the use of an intervention using social media to inform the patients, providers, or the public about a particular topic or issue that you have selected for your Informatics Scholarly Paper. To prepare to measure concepts that are a part of your paper, you will need to select an instrument to measure them. For instance, if you plan to teach something that may be a public concern such as a communicable disease, you will need to measure the organism that is infecting the public.

Then, you would want to measure the infection rate after you provide a social media outreach campaign to the public. You could measure the knowledge level of those that participated before and after you teach them. This is normally what is done in a DNP program when the student is conducting their project. To accomplish this, it is necessary to find the best instrument or tool. To do so, reviewing the current literature through a library search is best to look for articles. In addition, you will need to view the YouTube video below and quote one of the best explanations you found useful regarding reliability and validity. Keep in mind that the measure of reliability is conducted using a Cronbach’s alpha score, which should be within 0.70-0.90 for reliability of an instrument or tool to exist. If an instrument or tool is not within these parameters, it is not reliable.

Instruments or Tools

Select one of the instruments below that you think fits best with your topic and informatics theory. Review the corresponding peer reviewed article that explains the psychometric properties of the instrument, including the Cronbach alpha or reliability percentage. Share in your post what you have found.

Initial Post

• For your initial post, please pick one of the instruments or tools provided, read the peer reviewed article, examine the aspects of the instrument or tool, and explain the Cronbach’s alpha reliability coefficient score and usefulness. In addition, share with your peers how the instrument or tool will fit with your paper to use before and after your intervention. It may not be a perfect fit but pick one so we can go through the process.
