  1. aTo what extent participants expect the simple activity to increase or decrease their number of childbirth-related intrusive memories (0 = Extreme decrease; 20 = Extreme increase, 0 corresponding to No effect).
  2. bTo what extent participants find the activity easy, helpful, burdensome (1 = Not at all easy/helpful/burdensome; 10 = Extremely easy/helpful/burdensome).
  3. cTo what extent would participants be willing to do this activity again, if they had another UCS and the activity was scientifically shown to be useful (1 = Not at all; 10 = Absolutely).
  4. dTo what extent would participants recommend the activity to a friend who has had an UCS (1 = Not at all; 10 = Absolutely).
