Implementing dialectical behaviour therapy in routine practice: an evaluation of a national CAMHS DBT service for adolescents

Abstract Self-harming behaviours are reported to be increasing amongst young people and are associated with increased risk of suicide. The recently published UK clinical guidelines highlight that cross-sector awareness and early psychosocial assessment of self-harming is necessary, alongside careful triaging as to the level of support required. Dialectical behaviour therapy for adolescents (DBT-A) is a recommended intervention for young people with more severe difficulties. The current study aims to contribute to the data available to inform ongoing clinical decisions about the feasibility and implementation of DBT-A by reporting the intervention method, participant characteristics, and clinical outcomes of a national (UK) DBT service for young people with high levels of need and risk. Young people who commenced treatment between 2015 and 2021 were included. Completion rates, reasons for non-completion, and discharge pathways are reported. Measurement and changes in outcomes, including self-harm, in-patient bed days, accident and emergency department attendances and education/work status, are reported, as well as for routine outcome measures assessing emotion dysregulation and symptoms of emerging borderline personality disorder, depression and anxiety. The clinical significance of these outcomes are considered. Ideas for service evaluation, which are feasible and replicable in busy clinical settings are proposed, as well as a discussion of potential adaptations to standardised protocols needed in this context to fit with National Health Service (NHS) resources and the needs of the target population. Key learning aims (1) To learn about the implementation of dialectical behaviour therapy (DBT) and concurrent outcome monitoring in a UK National Health Service CAMHS out-patient setting. (2) To understand the clinical profile and response to treatment of young people with high levels of suicidal and non-suicidal self-harming behaviours. (3) To present a potential method for outcome monitoring and collection for CAMHS DBT services.
