Abstract
Objective: To investigate the effects of musical intervention on the anxiety level of patients undergoing treatment at a Psychosocial Care Center (CAPS) in southeast Pará. Methods: Quasi-experimental study, approved by the Research Ethics Committee, which involves 10 patients with the application of the Anxiety Inventory, before and after the musical intervention sessions. The 10-song musical repertoire had mostly positive messages and soft melodies. The data obtained was analyzed using descriptive statistics using the IBM SPSS Statistics software. Results: The highest proportion of patients is between 29 and 36 years old (40%), women (70%), incomplete primary school (30.0%), complete secondary school (30.0%), are single (60, 0%), have depression (40.0%), has been treated for at least 6 years (40.0%), takes controlled medications (90%), and has no other health problems (60%). There was a significant reduction in the mean level of anxiety, which went from 48.60 to 39.30 (p = 0.0001). Conclusion: Musical intervention showed that it can significantly reduce anxiety in patients with mental disorders. This study is a pioneer in the CAPS in question and music should be promoted in other centers.
