I am trying to develop a construct called social skills of interns who work in some K-12 schools. Interestingly, I used "I tried to avoid school leaders (reversely coded), "whenever I have difficulties, I talk to my lead university mentor" , " my colleagues are supportive" and "my way of communication with my colleagues has been improved" to develop a construct. Before doing any factor analysis, I tried to run a correlation analysis. I found that the first 2 are negatively associated . However, whenever either of them is independently placed in the same correlation analysis with the other 2 variables, they are positively associated with the other 2. How can this be explained? Can I interpret that there may be less communication between school leaders and college mentors? Or can I explain that this may be because that students develop some kind of habit of asking for help from the same individuals?
