I first thought of the work by Albert Bandura - who has written extensively in this field.
Eric Anderman, a member of ResearchGate, has written extensively (as listed on his page in ResearchGate) in this area, e.g. (as available in full text on RG):
Anderman, E. M., & Midgley, C. (1997). Changes in achievement goal orientations, perceived academic competence, and grades across the transition to middle-level schools. Contemporary Educational Psychology, 22(3), 269-298.
Perhaps he could give you further advice.
Another member of ResearchGate - Einar M. Skaalvik - has also done work on these topics. A paper he co-authored with Mimi Bong is available on ResearchGate. Perhaps he also could give you further advice:
Bong, M., & Skaalvik, E. M. (2003). Academic self-concept and self-efficacy: How different are they really?. Educational psychology review, 15(1), 1-40.
Other possible papers include two in the same journal - the initial paper is then discussed by Pintrich:
Murphy, P. K., & Alexander, P. A. (2000). A motivated exploration of motivation terminology. Contemporary educational psychology, 25(1), 3-53.
Pintrich, P. R. (2000). An achievement goal theory perspective on issues in motivation terminology, theory, and research. Contemporary educational psychology, 25(1), 92-104.
If you read the article "Effects of management by objectives : studies of Swedish upper secondary schools and the Influence of role stress and self-efficacy on school leaders" in Journal of Applied Social Psychology you will becomw inspired and get some new knowledge in this area.
