Objective: to evaluate the potential effectiveness of Balint groups with health professionals using an m-Health device called “Coletivos em Saúde Mental”, during the SARS-COV-2. Method: a quasi-experimental pilot study, developed in three phases: initial assessment; longitudinal monitoring and reassessment. Eight health professionals participated in the study, mean age of 35.5 years old, of different genders and with various schooling levels. The instruments used were the following: Demographic questionnaire; Mental health; Depression, Anxiety and Stress Scale; COVID-19 Fear Scale; Post-Traumatic Stress Disorder. The Balint interventions totaled 24 sessions using an m-Health device between December 2021 to February 2022. Results: the health assessment indicated mental distress: before, 75%; after, 50% (mean, 1.70±0.05 vs 1.54±0.05; SD=0.378; 0.377; p=0.387); depression: before, 62.5%; after, 12.5% (mean, 1.91±0.05 vs 1.50±0.05; SD=0.688; 0.497; p=0.242); anxiety: before, 50%; after, 37.5% (mean, 1.71±0.05 vs 1.98±0.05; SD=0.703; 0.624; p=0.208); stress: before, 75%; after, 37.5% (mean, 2.36±0.05 vs 1.98±0.05; SD=0.697; 0.547; p=0.260); COVID-19 fear: before, from 14 to 31; after, from 10 to 26 (mean, 3.57±0.05 vs 2.82±0.05; SD=1.043; 1.038; p=0.005), with a 100% reduction; post-traumatic stress disorder, re-experiencing the trauma: before, 37.5%; after, 12.5%; avoidance: before, 25%; after, 25%; hyperstimulation: before, 25%; after, 12.5% (mean, 2.11±0.05 vs 1.66±0.05; SD=0.734; 0.615; p=0.133). Conclusion: the findings of this study show the potential of Balint groups to promote health professionals' mental health. These results cannot be generalized and further research is required to evaluate the effectiveness of Balint groups.
