Introduction: Suicide is a leading cause of death globally. People with psychosis are at increased risk of suicide death and up to half experience suicidal thoughts and/or engage in suicidal behaviors in their lifetime. Talking therapies can be effective in alleviating suicidal experiences. However, research is yet to be translated into practice, demonstrating a gap in service provision. The barriers and facilitators in therapy implementation require a thorough investigation including the perspectives of different stakeholders such as service users and mental health professionals. This study aimed to investigate stakeholders’ (health professionals and service users) perspectives of implementing a suicide-focused psychological therapy for people experiencing psychosis in mental health services. Methods: Face-to-face, semi-structured interviews with 20 healthcare professionals and 18 service users were conducted. Interviews were audio recorded and transcribed verbatim. Data were analyzed and managed using reflexive thematic analysis and NVivo software. Results: For suicide-focused therapy to be successfully implemented in services for people with psychosis, there are four key aspects that need to be considered: (i) Creating safe spaces to be understood; (ii) Gaining a voice; (iii) Accessing therapy at the right time; and (iv) Ensuring a straightforward pathway to accessing therapy. Discussion: Whilst all stakeholders viewed a suicide-focused therapy as valuable for people experiencing psychosis, they also recognize that enabling successful implementation of such interventions will require additional training, flexibility, and resources to existing services.
