In the current study, a questionnaire to evaluate satisfaction levels and related factors upon discharge was completed by 100 patients receiving care for mental illness in a tertiary care hospital in Turkey. The relationships among sociodemographic variables, nonpharmacological interventions, and participants' views about the treatment course and quality of care they received were investigated. Overall satisfaction levels of participants were good. Older participants reported more positive opinions. Involuntary hospitalization, use of restraints/seclusion, or electroconvulsive therapy did not change overall satisfaction. Participants who were hospitalized for the first time were more afraid of other patients, which may imply that this population needs special care from the treatment team. Spending an adequate amount of time and providing necessary information about their treatment plan impact patients' treatment experience positively.
