There seems to be something quite odd about this--or it's just that I don't understand. So let's back up a bit to understand the story. You have 100 people, all of whom are receiving one of four drugs and you know which of the four drugs each person is receiving.
Did each person have a choice receiving each of the four drugs and they chose the one they are taking or did a unique somebody for each person decide which of the four drugs the person would receive or did a (as in one) somebody decide which drug each person would receive? Next, who did the ratings? The drug receivers or the drug chooser/choosers?
The question 2 ratings. Did the raters a) rate their drug choice relative to the other three possible drug choices, b) did they rate each eligible drug choice or c) something else. The wording of the rating task is critical to understand.
The question 3 ratings is not clear. Did they a) rate the drug that the person was receiving and not any of the other alternatives or b) something else? Let's say is was a). For the people receiving drug 1 what was drug 1 rated relative to?

Ok, lets see if I can explain myself better:
I would like first to understand if there is any relationship between the number of patients that are currently receiving drugs (q11_1, q11_2, q11_3,
q11_4) and the reasons when choosing drugs (q14a_1, q14a_2, q14a_3, q14a_4, q14a_5, q14a_6, q14a_7, q14a_8, q14a_9, q14a_10, q14a_11, q14a_12, q14a_13).
Second I would like to understand if there is any relationship between the number of patients that are currently receiving drug 1 (q11_1) and the reasons when choosing drug 1 (q15a_1, q15a_2, q15a_3, q15a_4, q15a_5, q15a_6, q15a_7, q15a_8, q15a_9, q15a_10, q15a_11, q15a_12, q15a_13). And also for the rest (drug 2, 3 and 4) which I haven't included any data.
Does that make any sense now?
Thanks in advance!
