You are part of an interprofessional team working on a study that looks at the relationship of perception of pain severity and quality of life in advanced cancer patients. Some of your colleagues think it is a cross-sectional design but others think it is a quasi-experimental design because it has several specific hypotheses. How would each group support their argument and how would you collaborate to resolve your differences? Why do you think it is important to have an team made of interprofessional members reviewing and being a part of your study?
