Five 18 week skills training groups based on Dialectical Behaviour Therapy (DBT) were provided for 34 participants with parasuicidal behaviours; 26 participants completed the programme. Monthly support/education groups for their keyworkers were also provided. Inpatient admissions decreased by 30% and out-patient appointments for those without admission by 61% over the 18 months from the initial pre-group formulation meeting, compared with the preceding 18 months. Statistical analysis (N = 17) showed significant reduction in CORE scores over the intervention period, and a similar effect in scores on the Work and Social Adjustment Scale. User satisfaction was high and drop out low (23.5%). Results indicate DBT skills group might be a useful service where full DBT is unavailable.
