Negative attitudes towards mental illnesses are an important problem that negatively affects both the social lives of individuals and the effectiveness of health services. Addressing these prejudices, developing empathy and promoting a patient-centred care approach are key goals that can be achieved through clinical experiences and structured educational programmes for nursing students. This single-centre, single-blind, randomised controlled trial aims to examine the effects of documentaries and psychiatric interviews on nursing students' implicit associations, discriminatory attitudes and empathy skills towards mental illnesses. Within the scope of the study, nursing students working in a psychiatric ward will be divided into two groups: one group will work with documentaries including psychiatric interviews and patient narratives, while the other group will only conduct psychiatric interviews. The Implicit Association Test (IAT) and the Attitudes Towards Mental Patients Scale will be used to assess students' implicit associations and attitudes towards psychiatric patients, and the Jefferson Empathy Scale will assess their level of empathy. Data analysis will be performed using SPSS 25.0 software. Given the widespread stigmatisation of psychiatric patients, this study is expected to make a significant contribution to improving the quality of care provided by nursing students in psychiatric settings.
