(Cost)-Effectiveness of ABFT for Suicidal Youth.

Young adults who attempt to kill themselves is a common and serious mental health problem worldwide and certainly in Belgium and the Netherlands. Fatal suicide is the leading cause of death among young adults. It has devastating consequences both for the young adults themselves and for their families. It also has substantial economic costs. However, up until now, there is little research on the treatment of suicidality among young adults. The current psychological therapy approaches and drug treatments for young people at very high risk of fatal suicide attempts have only limited success. Increasing evidence indicates the importance of involving significant others in treatment and the importance of the unfulfilled need for belonging and secure attachment. The WHO recommends involving significant others in the treatment of suicidal young adults. However, in Belgium and the Netherlands, there is little knowledge on the effectiveness of family based treatments. Attachment Based Family Therapy, or ABFT, was shown to work well in several studies in the US. Also in Belgium and the Netherlands, ABFT is being used to treat suicidal young adults. However, how well it works compared to the current treatment and if it provides good value for money have not been studied in young adults. In the proposed study the investigators will test, in a real-life situation, whether ABFT works better than the current treatment and if it provides good value for money. This study is a collaboration between the Netherlands and Belgium and 6 or 7 sites will participate from each country. Sites can be hospitals, mental health centres, student health centres or private practices. Participants (138 individuals) are young adults between 18 and 25 years old who have frequent thoughts about killing themselves, and who seek mental health treatment. The investigators predict that, compared to current treatment, ABFT will reduce suicidal thoughts and suicide attempts and that this improvement will be maintained over time, and that it will be better value for money. The project will contribute to improving care for suicidal young adults with high suicide risk. Results will inform clinical guidelines and policymakers and improve the treatment of young adults with a high risk for fatal suicide, and their families.
