Hypnotherapy for public speaking anxiety has a developing evidence base, and Norwest Wellbeing's own reported outcomes (a typical 80-85% success rate over 2-5 sessions) sit alongside this research rather than replacing it.
The most relevant controlled study is Schoenberger, Kirsch, Gearan, Montgomery and Pastyrnak (1997), published in Behavior Therapy. It compared a cognitive behavioural treatment for public speaking anxiety with the same treatment enhanced by hypnosis, plus a wait-list control. Both active treatments outperformed wait-list. The hypnotic version also produced larger average effects and higher expectancies for change, and on observer-rated fear during an impromptu speech, only the hypnotic group differed significantly from the control group.
Golden (2012), in the American Journal of Clinical Hypnosis, reviewed cognitive-behavioural hypnotherapy across anxiety disorders, including performance-related fears. The review concluded this combined approach appears at least as effective as behaviour therapy or CBT that already use imagery and relaxation, while noting that rigorous comparative trials remain limited.
Hammond (2010) reviewed hypnosis for anxiety- and stress-related conditions in Expert Review of Neurotherapeutics and found compelling evidence for several presentations, while recommending further controlled research on chronic anxiety patterns.
Valentine, Milling, Clark and Moriarty (2019), in the International Journal of Clinical and Experimental Hypnosis, pooled 17 trials of hypnosis for anxiety, including performance anxiety. They found a meaningful reduction in anxiety symptoms, broadly comparable to CBT, with benefits maintained or growing at follow-up.
Taken together, this research supports hypnotherapy as a reasonable, evidence-informed option for public speaking anxiety. It does not replace skills practice or a clinical assessment if broader social anxiety, panic, or another condition is also present.
