The purpose of the study is to evaluate the long-term efficacy of dialectical behavior
therapy (DBT) in treatment of adolescents with deliberate self harm compared to enhanced
usual care (EUC). This study follows-up 77 patients in the ages of 12-18 yrs who have been
included in an RCT of DBT-A vs EUC. The main inclusion criterion for this study was
repetitive self-harm behaviour. The patients were randomly allocated to receive 16 weeks of
outpatient DBT or EUC in child and adolescent psychiatric clinics in Oslo. Participants have
been assessed so far on five different time-points: baseline (before starting treatment), 9
weeks, 15 weeks, 19 weeks and 71 weeks after start of the treatment. In the current project
patients will be assessed a 6th time 2 years after treatment completion.
The main study hypotheses are:
- DBT will be significantly more efficacious in reducing the number of self-harm episodes
with or without intent to die, as well as reducing the number of emergency room visits
for self-harm or suicidal behaviour, compared to EUC.
- DBT will be significantly more efficacious in reducing the level of suicidal ideation
and depressive symptoms compared to EUC.
