Leonard Jason study - Changes in Activity & Perceived/Available Energy

[Dolphin]

I've also read studies where they make the assumption that drop-outs had no change (rather than checking to see if, oh, I dunno, maybe they got worse) and actually factor that assumption of no change into their final analysis.

Some of the studies use last value carried forward. So they're giving you CBT and GET and things may appear to be going fine, you answer questions, later on you drop out but they use the earlier values before you dropped out.
