Calculation Formula
Now, let’s get serious. The PHQ-15 score is calculated by assigning scores of 0, 1, 2, and 3 to the response categories of “not at all”, “bothered a little”, and “bothered a lot”. The total score can range from 0 to 30.
score = 0
for response in responses:
if response == "not at all":
score += 0
elif response == "bothered a little":
score += 1
elif response == "bothered a lot":
score += 2
