Study design
A randomized controlled clinical trial was conducted, wherein scores on dependent variables were compared before and after the intervention in both the experimental group (EG), consisting of individuals who participated in the BSP, and the control group (CG), comprising individuals who indicated that they would not modify their lifestyle during the study. The experimental procedures adhered to the CONSORT guidelines. The study protocol received approval from the University of León Research Ethics Committee (code: ULE-035–2022) and was registered on ClinicalTrials.gov with the ID: NCT05391165 (registered prospectively on 25/05/2022). All participants provided informed consent to participate, following the principles outlined in the Declaration of Helsinki (2013 version).
