I have data from a questionnaire to determine the level of diabetic foot care knowledge (DFCK) among undergraduate Podiatry students. The DFCK (i.e. outcome) is a score based on the total number of the right answers given by the students for 25 questions related to podiatry.

I want to determine whether there is an association between certain characteristics of the students like age (categorical: < 25 and >=25), gender (M/F), podiatric clinical interest (a list of clinical interests from which the students can choose one or more interests), previous degree (yes/no), previous diabetic foot care experience (yes/no), personal or family history of diabetes (yes/no) and DFCK among undergraduate Podiatry students.

I am doing a Mann-Whitney test for all the variables to determine whether they are associated with DFCK score but podiatric clinical interest.

As the podiatric clinical interest is a multiple choice question, can someone please help me what method to use to determine whether it is associated with the DFCK score.

my data looks like this. enter image description here

A (too?) simple approach would be to transform your podiatric interest variable into multiples dummy variables (one for each interest, i.e. Diabetes : yes/no, Routine : yes/no, etc.) and perform Mann-Whitney tests as previously. But this won't work if you are more interested in the association between interests.
