Brief Summary

Objective: To establish whether the pilot online hypnosis design was well received by women with persistent pelvic pain and worthy of a full randomised control trial To establish whether hypnosis improves mental health outcomes, including anxiety, depression, life impact and catastrophizing, in women with chronic pelvic pain conditions.

Detailed Description

Design: Pilot Randomised Control Trial Methods: Twenty women with persistent pelvic pain completed assessment questionnaires and were recruited from a variety of social media sites related to persistent pelvic pain and randomly allocated to either control or hypnotic intervention groups. The intervention group completed a seven week online hypnotic intervention. The control group received no intervention. Both groups completed assessment and concluding questionnaires related to demographic information and the outcomes of interest. This included measures for anxiety, depression, pain, coping styles, pain related disability, pain catastrophizing and suggestibility. The results of the intervention and waitlist control groups were compared using linear mixed-effects modelling. Suggestibility was screened for at baseline using the Short Suggestibility Scale, and included in a secondary set of linear effects modelling.

Feasibility of hypnotic intervention according to qualitative responses from women with persistent pelvic pain.	7 weeks	Whether hypnosis was received well by women with persistent pelvic pain in the intervention group according to their qualitative responses during and after the study. Qualitative responses were collected in open text box format and analysed for themes using the thematic analysis software contained in the SurveyMonkey online software.
