I am working on my Ph.D. dissertation entitled "Motivation in the Military, Case of the Lebanese Army-Special Units."
I am trying to study the impact of soldiers' motivation on their level of performance
I am using two tools in my study, one for measuring Motivation (dependent variable) and the other for measuring performance (independent variable)
Regarding Motivation, I found a tool used by Allison C. Patterson in her thesis “The Goal of Motivation in the Military: Soldier Satisfaction or Soldier Performance.”
Any recommendation for a tool to measure Performance?
