Is this qualitative or quantitative?

Using the study, A Randomized, Clinical Trial of Education or Motivational-Interviewing-Based Coaching Compared to Usual Care to Improve Cancer Pain Management, which is Appendix A in your text, answer the following. 

• Is this a qualitative or quantitative study?  State your rationale for your answer.
• What is the study design?
• Is the design appropriate for the research question/hypothesis?
• What are some possible threats to internal validity?

   

  This doesnt have to be in a certain format and there isnt a requirement on the word count. As long as all parts of the question are answered, I should be okay.
