Self-administered acupressure for insomnia disorder : a randomized controlled trial

Abstract

Background: Insomnia is a significant health problem in the community. Self-administered acupressure (SAA) may be an alternative strategy to alleviate insomnia. Purpose: This study is the first to investigate the effects of SAA delivered through a training course in alleviating insomnia disorder compared with sleep hygiene education (SHE). Methods: A randomized controlled trial was conducted on 200 participants with insomnia disorder. The eligible participants were randomized into the SAA or SHE group. Both groups attended the allocated training courses (two sessions, 2 h each) and then were followed up at weeks 4 and 8. The primary outcome was the severity of insomnia symptoms and related daytime impairment as measured by the Insomnia Severity Index (ISI). Other measures included a 7-day sleep diary and actigraphy, Hospital Anxiety and Depression Scale (HADS), and Short-Form Six-Dimension (SF6D). Results: The SAA group showed a significantly greater improvement in ISI score than the SHE group at week 4 (mean difference: -1.89 units, 95% CI: 0.85, 2.93; Cohen's d = 0.51, p < 0.001) and week 8 (mean difference: -2.89 units, 95% CI: 1.67, 4.11; d = 0.67, p < 0.001). In addition, the SAA group showed a greater reduction in the HADS anxiety score and HADS depression score and increase in SF6D at week 8. Conclusions: SAA taught in a short training course is a feasible and effective approach to improve sleep and related daytime impairment and mood problems in individuals with insomnia disorder.
