# How to analyse pre-post quasi-experimental study with an additional baseline measure?

I am having a hard time with what seems to be a very basic research design issue.

The study has 3 variables:

• Self-control and adjustment are the main ones, since they were measured in pre and post tests, before and after a year long social and emotional program in two different high schools. (I guess this part of the design would be quasi-experimental)
• The third variable is values in interpersonal relationships. This was measured only one time at the beginning of the program since it tends to be more permanent. Also, the program wasn't designed to have an effect on this, except values can also affect the adjustment and self control of the students. The results show the groups tend to the individualist values vs. collectivistic ones (descriptive design).

I wanted to add hypothesis about this last variable to my paper, but a teacher told me it would be better not to include those, since those are more descriptive hypotheses.

• What is the best and correct way to include all this information on the paper, so it´s statistically sound?
