Main topic of my dissertation. A critical issue in my research is how to measure intrinsic job motivation. Constructs based on Likert Scales is mostly used in literature. However, ordinal data is good to present a status rather than make calculation. ("Strongly agree" is not two time stronger than "Agree") Thus, Rasch model could be a good solution.  I am not quite sure why Rasch model is not very popular among motivation researches.

Motivation research is one of the main branch in organizational behavior field. It focus on three fundamental questions:  (1) Why do we initiate effort on a task? (2) How much effort do we choose to expend? (3) Why do we persist in working at the task over time?” (Mitchell,1979) They are almost the equivalent of the ultimate question of why humans behave the way they do. At least in social sciencet, it will certainly have no "correct" answer. Maybe we need to know how brain works first. However, people desperately what to know a general answer. By popular demand, scholars built Achievement Motivation Theory, Equity Theory, Expectancy Theories, Goal-Setting Theory, etc. All of them are quite convincing from their own perspective. I will post my literature review here after I finish my dissertation. Before that, Miner's book in 2005 and Latham & Pinder's review are very good sources.

I am still working on my dissertation. So, nothing more could be disclousure online.
