Hello. I answered the interesting questions on your survey. If your research question consists of "is there a relationship between professional nursing work and stress?", you probably will not have any difficulty in measuring a definite relationship. One idea for further research is to study the relationship between professional nursing stress and stress management classes. The focus of most inservice education for professional nurses tends to be about important topics other than stress management ( medications, treatments,emergency skills,patient advocate issues, and nursing staff management challenges). Maybe in your research you could make a good "case" for public health officials to highly advise employers to provide periodic stress management classes for all high stress level employees such as police, fire fighters, and nurses? Best wishes.
