Study data were collected by the researcher through face-to-face interviews. The study included individuals diagnosed with schizophrenia who met the inclusion criteria (registration in a CMHC, having a diagnosis of schizophrenia, willingness to participate in the study, and openness to communication and collaboration). Pre-test measurement instruments were administered to the participants. The experimental group received eight sessions of respiratory therapy. The control group received no intervention. Post-test data were collected following the training sessions.
