Researchers from Medical Department Oslo University Hospital in Norway investigated the impact of self-administered relaxation, guided imagery and positive affirmations during the latter part of pregnancy on the experience of childbirth.
Subjects with no prior training were given a CD and accompanying booklet and compared with treatment as usual in this randomized, controlled clinical trial.
Amount of pain and anxiety were measured during different stages of birth and after delivery. Post-delivery Wellbeing (Edmonton Scale), pain, anxiety, Apgar score, duration of birth, complications and degree of anesthesia/analgesic used were recorded. Those in the CD-intervention group also reported how many times they had practiced.
The study found that the CD-intervention group had a significantly better score on total Wellbeing, as measured by the Edmonton Scale.
