Q

What are the key mechanisms of effective treatments to optimize changes?

A
  • refining interventions by distilling them to their most essential elements
  • teaching providers what key elements need to be delivered
  • helping providers understand how to individualize treatments in a way that will maximize effects

Q

What are some difficulties with mechanisms?

A
  • how do we find them?
  • need to know what causes the target
  • unclear for most psychological targets
  • need to experimentally manipulate to determine the importance on the distal outcome
