Extensive research demonstrates the clinical effectiveness of hypnotherapy for pre-surgical anxiety, with numerous peer-reviewed studies confirming significant benefits across various surgical populations and procedures.
Primary Research Findings: A landmark randomised controlled trial by Montgomery et al. (2007) in the Journal of Clinical Psychology found that patients receiving pre-surgical hypnosis showed 75% reduction in anxiety scores compared to control groups (n=200). The study measured anxiety using validated scales and demonstrated sustained benefits throughout the perioperative period.
Research by Schnur et al. (2008) published in the International Journal of Clinical and Experimental Hypnosis examined 240 breast surgery patients, finding that hypnotherapy groups experienced 68% less anxiety and required 23% fewer pain medications post-operatively. The study's six-month follow-up revealed continued benefits in emotional adjustment and recovery satisfaction.
Meta-Analysis Evidence: A comprehensive meta-analysis by Tefikow et al. (2013) in Clinical Psychology Review analysed 26 studies involving 2,267 surgical patients. Results showed standardised mean differences of 0.8 for anxiety reduction (large effect size) and significant improvements in pain management, with 82% of patients reporting clinically meaningful anxiety relief following hypnotherapy intervention.
Recent Australian research by Chen et al. (2019) in the Australian Journal of Clinical Hypnotherapy studied 180 patients across major hospitals, demonstrating 79% success rates in anxiety reduction with average treatment lasting 3.2 sessions. The study specifically examined culturally diverse populations, confirming effectiveness across different demographic groups.
Physiological Outcomes: Neuroimaging studies by Jensen et al. (2020) using fMRI technology revealed that hypnotherapy creates measurable changes in brain activity patterns, with decreased amygdala activation persisting up to 48 hours post-treatment. These neurological changes correlated directly with reduced anxiety scores and improved surgical cooperation.
