I plan on using the Emotional Intelligence framework and areas-of-work-life (AW) framework, with the MSCEIT and MBI as my tools in a quantitative study. I am leaning towards a correlational study using multiple linear regression.
Mine is more of an analysis paper right now and I am having a difficult time locating 5 research studies based on my thoughts. My guess will be that Hashimoto's will need a study at least at this point based on the little amount of evidence I am able to find.
The level of burnout can be measured by using a scale of Burnout. One such published scale's citation -
Malach-Pines, A. (2005). The burnout measure, short version. International Journal of Stress Management, 12(1), 78.
First, you might also need a scale such as DASS to measure the level of Anxiety and Stress of leaders. Then, identify the sample from which you collected the data who have high anxiety and stress. After that, you can use the Burnout Inventory on this sample only.
