Why is this an issue : evaluation of CBT in SZWatch this thread
Kopelowicz + Liberman (1998) found relapse rate was moderate and treatment deemed to be moderately expensive. Why is this an issue?
I cant come up with more points
It shows that they are not effective
If the treatment is also expensive it makes the study less applicable to the real world, as it makes it more difficult to carry out.
hope this helps!
