The goal of this study is to determine whether Brief Cognitive Behaviour Therapy (BCBT), a four-session psychological treatment aimed at reducing suicide attempts, is acceptable and feasible to deliver during psychiatric inpatient care for adults who have been hospitalised following a suicide attempt or who are at high risk of suicide. The main questions it aims to answer are:
1. Is BCBT acceptable among suicidal psychiatric inpatients, and in what ways can the treatment and its delivery be improved to enhance patient engagement and adherence?
2. Is BCBT feasible from the perspectives of treating clinicians, clinic managers, and other relevant personnel, and what are the key facilitators and barriers to its implementation within routine inpatient psychiatric care in Sweden?
Participants will:
* Receive four structured BCBT therapy sessions delivered during hospitalisation, in addition to usual care
* Be contacted for follow-up assessments at 1 and 3 months after completing treatment
* Take part in an interview about the participants' experience with the treatment 1 month after completing it
Clinical staff, treating psychologists, and managers will also be interviewed to explore the participants' experiences, as well as barriers and facilitators to implementation. Overall, the findings from this study will inform the design of a future randomised trial to test the effectiveness of BCBT in reducing suicide attempts after discharge from inpatient psychiatric care.
