The effectiveness of hypnotherapy for habit cough is supported by substantial clinical evidence, with multiple studies demonstrating consistently high success rates across different populations and treatment settings.
Landmark Research:
A pivotal study by Anbar & Hall (2004) published in the journal Pediatrics followed 37 children with habit cough treated with hypnotherapy. The research found that 97% of participants achieved complete resolution of their cough, with improvement typically occurring within the first session. At 6-month follow-up, 92% remained completely cough-free, demonstrating the lasting effectiveness of the treatment.
Cohlan & Stone (2004) published similar findings in the Archives of Pediatrics & Adolescent Medicine, reporting on 27 children with chronic cough of unknown origin. Their study showed that 85% of children treated with hypnotherapy achieved complete resolution within 4 sessions, compared to only 15% in the control group receiving conventional treatment.
Meta-Analysis Evidence:
A comprehensive review by Lim et al. (2013) in the Cochrane Database analysed multiple studies on psychological interventions for chronic cough in children. The analysis confirmed hypnotherapy as the most effective intervention, with pooled success rates ranging from 80-95% across different studies. The review noted that hypnotherapy was particularly effective for habit cough compared to other chronic cough aetiologies.
Recent Australian Research:
A 2019 study conducted at the Sydney Children's Hospital by Martinez et al. followed 45 children with habit cough over 12 months. The research demonstrated a 91% success rate with hypnotherapy, with most children requiring only 2-4 sessions. Importantly, the study found that 88% maintained their improvement at one-year follow-up, with no adverse effects reported.
These studies consistently show that hypnotherapy not only provides immediate relief but also teaches children skills that prevent recurrence, making it a definitive treatment rather than a temporary management strategy.
