Self-harm (deliberate overdoses, cutting, burning, banging head, ligatures)


The experimental group therapy intervention is a manualised treatment specifically designed for adolescents who harmed themselves. The group treatment is based on cognitive behaviour and problem solving techniques. Techniques used in the group integrated empirically based conceptual approaches in common clinical practice within the NHS and advocated by several opinion leaders in the field of deliberate self harm. Participants were asked to attend four group therapy sessions. After this, they can access the group for as long as they are open to CAMHS.

Comparator - Routine Care:
Clinical centres provide routine care that they would normally provide to these patients. Treatment as usual is undertaken by the local CAMHS Team using established protocols and clinical practice. Centres agree that routine care will not include any group intervention.

For both arms of the trial, treatment was given for as long as the Care Manager though it was clinically needed. Some participants were in treatment for over a year.

Primary outcome measures

Frequency and severity of episodes of self harm assessed using an adapted self harm interview schedule. Steps will be taken with the interview schedule to minimise a recall bias towards more recent events and to get a clear picture of the pattern of self harm over the previous year. The self harm interview will be conducted by research assessors (blinded to treatment allocation) and additionally (to allow for reporting bias from young people) clinicians involved with the young person will also undertake the same interview.

Secondary outcome measures

1. Time to first and second repetition, number of severe suicidal acts (defined by medical risk of death)
2. Depression measured using the Moods and Feelings Questionnaire (MFQ)
3. Suicidality measured using the Suicidale Ideation Questionnaire
4. Global outcome assessed by the health of the nation outcome scales for children and adolescents (HoNOSCA)
5. Psychosocial stress assessed using the Kiddie Schedule for Affective Disorders and Scizophrenia (K-SADS)
6. Cost benefit analysis measured using the Service Use Inventory

All the above administered at baseline, 6 and 12 months. At 3 months an assessment to measure emerging personality problems was undertaken (SCID II).
