The Effects of Qigong on Anxiety, Depression, and Psychological Well-Being : A Systematic Review and Meta-Analysis

Abstract EN

Introduction.

The effect of Qigong on psychological well-being is relatively unknown.

This study systematically reviewed the effects of Qigong on anxiety, depression, and psychological well-being.

Methods.

Using fifteen studies published between 2001 and 2011, a systematic review was carried out and meta-analyses were performed on studies with appropriate homogeneity.

The quality of the outcome measures was also assessed.

Results.

We categorized these studies into three groups based on the type of subjects involved as follows: (1) healthy subjects, (2) subjects with chronic illnesses, and (3) subjects with depression.

Based on the heterogeneity assessment of available studies, meta-analyses were conducted in three studies of patients with type II diabetes in the second group, which suggested that Qigong was effective in reducing depression (ES=−0.29; 95% CI, −0.58–0.00) and anxiety (ES=−0.37; 95% CI, −0.66–0.08), as measured by Symptom Checklist 90, and in improving psychological well-being (ES=−0.58; 95% CI, −0.91–0.25) as measured by Diabetes Specific Quality of Life Scale.

Overall, the quality of research methodology of existing studies was poor.

Conclusions.

Preliminary evidence suggests that Gigong may have positive effects on psychological well-being among patients with chronic illnesses.

However the published studies generally had significant methodological limitations.

More high-quality studies are needed.
