Mental Health and Psychiatric Nursing is a specialised course designed to equip nursing students with the knowledge, skills, and professional attitudes required to promote mental well-being, prevent mental illness, and provide holistic care to individuals experiencing psychiatric disorders. The course explores key concepts such as mental health and mental illness, the mental health continuum, therapeutic communication, and the biopsychosocial factors influencing behaviour. It also covers the assessment, diagnosis, treatment, and rehabilitation of individuals with common and severe mental health conditions across the lifespan. Emphasis is placed on evidence-based practice, ethical and legal considerations, and culturally sensitive care within both hospital and community settings. By the end of the course, students are prepared to deliver comprehensive, person-centred mental health care and to contribute effectively to multidisciplinary teams in diverse healthcare environments.
