A physicаl therаpist wаnts tо knоw if stress management techniques prоduce an improvement in pain management for patients with chronic neck pain. A quasi-experimental study design that compares a control group vs intervention group was completed. The intervention consisted of a one-month stress management program. The outcome variables of pain intensity and Neck Disability Index (NDI) (both measured as continuous variables) were collected at the end of treatment, 3-months and 6 months follow up.    To assess treatment effectiveness, both groups were compared by the variable of pain at the end of treatment, 3 months and 6 months follow up.  What statistical test do you expect to be used to compare each group improvement from baseline to all follow up points?
