In summary, the current findings raise questions as to the validity of the
factor structure of the MSI, specifically in an Irish context, and suggest that
further study and investigation of its reliability are needed. The apparent
weaknesses of the MSI, as the sole instrument designed to measure the
motivational concepts contained within Leonard et al.’s (1999) meta-theory
of motivation, may also be contributing to the lack of research and development
on the meta-theory. Re-examination and possible refinement of the
MSI or development of an alternative instrument may serve to promote
further research in this area
