Enhanced Brief CBT for Suicidal Inpatients With Mood Disorders

The goal of this clinical trial is to evaluate whether enhanced brief cognitive behavioral therapy (E-BCBT) can help reduce suicidal thoughts and behaviors among psychiatric inpatients. This therapy is designed to be feasible during hospitalization and includes self-directed worksheets that may later be used independently after discharge, offering potential benefits for suicide prevention outside the hospital setting as well. Participants will be randomly assigned to one of two groups: * E-BCBT group: Participants will receive five sessions of cognitive behavioral therapy (approximately 50-60 minutes each) during their inpatient stay. * TAU (treatment as usual) group: Participants will receive standard care provided on the psychiatric ward. All participants will take part in five assessments: one before treatment, one after treatment, and three monthly follow-up assessments over the three months after discharge. Assessments include interviews, conducted in person or by phone, and questionnaires, completed online via a survey link. The entire study period will take approximately four months.
