Q

Why is SD good for treating fear of flying?

A
  1. Confrontation exposure - ppl travel on planes but still scared
  2. Can be used in vitro - not easy to recreate all scenarios in vivo
  3. Less dependent on therapist - success rate higher
  4. SD not as stressful as flooding - ppts more likely to stick to treatment
