That would depend. Where a 75+ means a trait or disorder is likely present (which isn't the verbatim psychological response) its based on a spectrum of sorts depending on other factors within the test.
The first step is to evaluate the MCMI (which isn't as easy as it sounds honestly), interview the client at length, and then follow up with specialized or additional assessments.
The drug and alcohol segments would depict dependency though, possibly. Knowing what we know of her though such a dependency seems unlikely but because of that score I'd expect follow up to focus in part there. Honestly JMO from the little I know of it.
Meanwhile, found this interesting too:
