Pilot study of acupuncture to treat anxiety in children and adolescents.

AIM: This pilot study investigated the use of acupuncture in the treatment of paediatric anxiety. METHODS: Children with anxiety, aged 8-16, were randomised to either the acupuncture or waitlist control groups. Anxiety was measured using the Hamilton Anxiety Rating Scale (HAM-A) for children and adolescents with generalised anxiety disorder and Multidimensional Anxiety Scale for Children 2nd Edition (MASC-2) self-rated and parent-rated forms. RESULTS: Twenty participants were enrolled in the study and 19 completed all the questionnaires to be included in the analysis. There were no differences in socio-demographic characteristics at baseline between the two groups. At the second assessment, the mean MASC-parent score for the acupuncture group was significantly lower than the waitlist group (65.6 (SD 15.0) compared to 81.0 (SD 11.9), P = 0.025) with an effect size = 1.13. The pre- and post-treatment comparisons were also significantly lower for both groups in the anxiety measures. In the acupuncture group, MASC-parent (P = 0.008, effect size 0.75) and the HAM-A (P < 0.001, effect size 1.4). In the waitlist group, MASC-self (P = 0.022; effect size 0.4), MASC-parent (P = 0.048; effect size 0.75) and HAM-A (P = 0.007; effect size 1.21). CONCLUSIONS: This study provided promising results on the potential use of acupuncture to treat children and adolescents with general anxiety. Future research using a randomised control trial with a sufficient sample size to control for confounders and sham (placebo) comparators is warranted.
