Answer:
Not following the theory completely.
Step-by-step explanation:
According to Talcott Parson's Role Theory, there are two aspects to it, the patient has rights and also obligations.
The theory states that the patient can not be blamed for their illness and they have the right to be treated with patience. But the patient also has to acknowledge the disease and make efforts towards getting the right treatment and getting better without solely depending on people around.
In the example given in the question, Melinda is clearly not fulfilling her responsibilities in terms of seeking treatment and making efforts.
I hope this answer helps.
