Kevin Gournay qualified as a Registered Nurse in 1972. Soon after, he completed an 18‑month course in Behavioural Psychotherapy at the Maudsley Hospital in London under the supervision of the pioneering psychiatrist Professor Isaac Marks. At the time, this was an exceptional opportunity—very few post‑registration courses existed for mental health nurses in the UK. The programme was highly skills‑focused, and Gournay became one of the country’s few Behavioural Nurse Therapists. This early training shaped the trajectory of his entire career, and he remained clinically active even as he moved into academia and research.

Gournay believed deeply in the powerful and transformative role nurses could play in mental health care. His combined clinical and academic expertise placed him in a strong position to influence both practice and policy.

Over several decades, in the UK and internationally, he helped shape not only how mental health nursing was practised but also the direction in which it evolved. His experience as a Nurse Therapist gave him the insight to recognise that mental health nursing needed to advance its scope and sophistication. Through research and policy work, he consistently identified areas where practice could be strengthened—across primary care, acute inpatient services, prisons, and high‑secure hospitals.

By the early 1990s, concerns had grown that the work of Community Psychiatric Nurses (CPNs) had drifted away from supporting people with serious mental illness. Many CPNs were increasingly focused on short‑term crises and less severe conditions. A landmark study revealed that only 27% of people on CPN caseloads had a diagnosis of schizophrenia, and around a quarter of CPNs had no patients with schizophrenia at all.

Gournay, alongside a group of multidisciplinary colleagues, sought to address this gap. Their efforts led to the development of the Thorn Initiative, a movement that brought together leading figures in mental health practice and research. Initially launched in London and Manchester, the Thorn courses—later known more broadly as psychosocial intervention programmes—were designed primarily for mental health nurses, who were the professionals working most closely with people with schizophrenia. As their value became recognised, the programmes spread across the UK.

These courses challenged traditional, non‑evidence‑based approaches that had limited impact or, in some cases, caused harm by denying people access to effective interventions. At the time, the prevailing nursing approach to psychosis was to avoid engaging with symptoms such as delusions and hallucinations, assuming that only medication could help. Gournay and other forward‑thinking practitioners challenged this view. They argued that nurses could—and should—work directly with service users to help them understand and manage their experiences, reducing distress and improving functioning.

The psychosocial interventions movement introduced evidence‑based approaches including family interventions, physical health improvement, medication education, dual‑diagnosis work, and cognitive behavioural therapy for psychosis. These interventions aimed to instil hope, support carers, enhance social and clinical outcomes, and improve quality of life. Gournay went on to establish the first multidisciplinary master’s programme focused on interventions for serious mental illness.

The impact of this work was transformative for nurses, service users, and families. Research has consistently supported the effectiveness of these interventions, and many practices now considered standard in working with people with serious mental illness emerged from this period of multidisciplinary innovation.

Throughout his career—as clinician, researcher, writer, policy influencer, and educator—Gournay continually challenged mental health services to adopt more evidence‑based approaches. His work not only improved practice but also shaped national policy. Importantly, his collaborations with other professionals and academics helped position nurses as central contributors to the development of modern mental health care.
