| Summary: | 碩士 === 南華大學 === 自然醫學研究所 === 95 === The main objective of this study is to assess the effectiveness of hypnotherapy in the treatment of depressive disorder and depressive mood. As these two depressive conditions are different, separated analyses were conducted. A systematic review was performed to assess the effectiveness of hypnotherapy for depressive disorder and meta-analysis was used to provide a quantitative pooled estimate of the effect of hypnotherapy for depressive mood.
To identify the literature, seven electronic databases (PubMed; The Cochrane Collaboration Depression, Anxiety and Neurosis Review Group (CCDAN); Cochrane Library; Ebsco-Medline; PsiTri; PsycLit; and Embase) and a website (Google Scholar) were searched. Five studies (n=1167) were identified in the systematic review of hypnotherapy for depressive disorder(n=185). None of the studies were able to clearly demonstrate the effectiveness of hypnotherapy in the treatment of depressive disorder. Six studies (n=314) that fulfilled the inclusion criteria were included in the meta-analysis of hypnotherapy in the treatment of depressive mood. A combined effect -0.566 (p<0.001) was estimated with the Comprehensive Meta-Analysis, Version 2 software.
Future studies should pay attention to the study design and adopt the use of control group, double-blind, randomization, and adequate sample size to reduce experimental bias and enhance the statistical power. The report of the experiment should also be recorded accordingly to the Consort Checklist for the benefit of future meta-analysis to be carried out. Findings from this study showed that hypnotherapy has medium level effectiveness in the treatment of depressive mood while the effectiveness of hypnotherapy in the treatment of depressive disorder is still unclear. The application of the hypnotherapy in the treatment of mood disorders is still in its infancy stage but the findings are encouraging for further research.
