Actually, the placebo effect has a bad rap (note: I’m really impressed by the smart questions you get on this site; this is a treat) in that it does reduce pain, remove depresion and increase confidence. If you want it do these things, the goal is to so in the most cost effective manner (and not have people buy 20,000 dollar magic healing crystals). It becomes problematic as people extend the placebo effect beyond what it can do to doing things like curing cancer and the like. As a treatment for self-efficacy, yes it is a good idea as believing does make it so (in this case).
