Abstract Objective: to assess the effectiveness of auriculotherapy in reducing occupational stress among Family Health Strategy workers during the COVID-19 pandemic. Method: a controlled randomized clinical trial divided into two groups, namely: auriculotherapy for stress group and placebo group. The Shapiro-Wilk test was used to assess data normality. The ANOVA test for repeated measures and the Tukey post-hoc test were applied to the group with normal samples. In turn, the Friedman and Durbin-Conover tests were employed in the group with non-normal distribution. Cohen’s d index was calculated for the therapy effect size. A 95% significance level and p<0.05 were considered. Results: the auriculotherapy group presented 16.3% and 23.7% reductions in occupational stress after the third and sixth auriculotherapy sessions, with Cohen’s d indices of 1.12 (large effect) and 1.82 (very large effect), respectively. Conclusion: auriculotherapy proved to be effective in reducing occupational stress among Family Health Strategy workers during the COVID-19 pandemic. It is suggested that new studies are developed both during and after the pandemic in order to improve health workers’ Quality of Life. ReBEC registration: RBR - 38hjyt3.
